Plumbing, Head, Part 9, Finishing Touches

The new head, fully replumbed
Having completed many subprojects in the replumbing of the head of Oystercatcher, my Ericson 25, all I needed to do now was to add a few finishing touches to call this full makeover of the head a done deal.
When I purchased the boat in the fall of 2009, she had a toilet paper roller. Now I needed to figure out where to reinstall it. This seemingly simple task actually ended up taking a considerable amount of time, only because I had the installations of several other components to take into consideration in this limited space. I had a custom built magazine rack; I had a custom built Maptech chart rack; and I had a small trash can that I needed to fit within this head.
Ultimately, I decided to mount this roller in the narrow space between the discharge hoses. It didn't encroach on the user's space, it provided easy access, and it occupied space that was out-of-the-way and otherwise wasted. Yes, we're talking about toilet paper, but after all the time and effort and money I had put into this project, I took this subject seriously. Besides, it had to be something that the Admiral would find acceptable. Otherwise, my lovely bride would remind me of this ad infinitum.
The latch for the mahogany door was another issue that I had to address. This was on the exterior of the door. The previous owner obviously had installed it for the purpose of keeping the door from swinging back and forth while the boat was underway or docked or at anchor.
It appeared that he had adjusted the catch for the latch several times. There were numerous screw holes here and there. In my experience the swing of the door can vary by as much as 1/8 inch, depending upon how the boat sits on the trailer or depending upon how you tie the boat up to a dock. I suppose it's just an expression of the natural flex of the hull.
I readjusted the catch, so that the barrel bolt would easily pass back and forth. Later, after I launched the boat, there was again a lot of friction between the bolt and the catch. I suppose there is no way around this issue, unless you adjust the catch depending upon whether you're tied up at the dock or sitting on the trailer.
The door never possessed a handle. I found this a little strange. The only way you could open it from the outside was to grasp the the little protrusion on the barrel bolt. This was uncomfortable. The only way you could shut it on the inside was to grab the eye for the hook-and-eye latch and pull it toward you. I was tried of this foolishness. Therefore, I purchased two solid brass handles from my local hardware store. These were actually marketed as window sash handles, but to me they were marine grade door handles. These cost me a little over five dollars a piece. Similar solid brass "marine" door handles at chandleries were four or five times the price. I considered using a spare stainless steel cleat, but I was worried that things might get snagged by it.
Here's a view of the underside of these solid brass handles. Yes, they were solid, not brass plated zinc.
I didn't just grab the drill, put a screw on the bit, and drive it into the mahogany. I thought the whole thing out and figured out the best location - the one that felt most natural and looked most natural for this space.
Nice and plumb, nice and level. If I'd paid someone to do it, I bet it would have been crooked. Have you ever noticed how crooked some things are these days - pieces of trim, electrical receptacles, even chimneys? I'm not kidding. A few years back I saw a crooked chimney in one of those neighborhoods they slapped together in a few month's time. So this is the work of professional carpenters, electricians, etc.? Whatever happened to craftsmanship? It's good that there are some who still practice it. They're just hard to find. I know a few, and they're amazing.
I installed the interior handle at a slightly different height so that the screws for the two handles would not interfere with each other.
The handle made the closing of the door much more simple. No more grabbing of the eye with your index finger and thumb.
I decided to install the custom mahogany chart rack on the bulkhead, between the discharge hose and the conduits for the mast wiring. As was the case with the location for the toilet paper roller, this one was high and out of the way. You might ask why I installed this chart rack here, rather than in the main salon. The answer is that there was no room for it there. It was easy to reach around the bulkhead to access these charts, so I figured that it would be just fine.
I considered installing the custom mahogany magazine rack on the opposite bulkhead, but ended up deciding to install it on the back of the door. As you can see, it does not encroach on the user's knees, and it provides easy access to that reading material that so many find so essential to a space such as this one. By the way, those are knee pads on my knees. They were an essential part of my work gear during this refitting. Some might find kneeling on fiberglass comforting. I never have.
After I had completed the installation of the above described components I climbed up on deck and took a picture of the head while looking down through the forward hatch. This was shortly before I relaunched the boat after this lengthy refitting.
Before I launched, I made sure to add some wooden plugs to the head. As I recall, I ordered these from Defender in Connecticut.
I taped these to the hull liner with some Gorilla brand duct tape, not far from the through-hulls.
After the boat came off the trailer, my friend tied the boat to the dock while I pulled the trailer out of the water and parked. The first thing he did was to inspect the through hulls. Fortunately, he found no leaks.
I leased a slip and docked the boat. Every day for the first several weeks I visited the boat and inspected the through-hulls. Again, good news.
During this time I continued to add some finishing touches to the head - some finishing touches that I didn't have time to complete prior to the launch. One of these was the installation of the trash can. This I joined to the bulkhead with black shock cord. This was the perfect place for this trash can. It was easy to access, and it was out of the way. I also added a canister of Lysol wipes. This I joined to the bulkhead with black shock cord. Why was a trash can necessary? Read on to find out.
On the other side of the toilet I installed a plastic basin with a Scotch-Brite pad dedicated to the head. Notice that I have cut a certain number of corners off of the pad to indicate that this pad belongs in the head. There were other pads in the galley with a different number of corners removed to signal their purpose. This was something I had learned on the tall ships on which I'd sailed.
Also at this time I shoved a wad of gray plastic grocery bags behind the hose for the Whale brand manual pump. This was a convenient place for them, especially because I would need them often. These bags fit the trash can perfectly. Spare rolls of toilet paper and cleaning supplies I stowed in dedicated spots within the hanging locker opposite the head.
I never left the handle for the toilet's pump in the handle housing. I only put it there while flushing the toilet. Otherwise, I stowed it behind the mags in the magazine rack.
During this early period, not long after the launch, I was also taking regular trips from the boat to the marina office to use the the marina head. There was great reluctance on my part to use the head. It was so pristine . . . and what if, after all this work, it itself did not work? That was my thinking. Finally, having grown tired of walking back and forth to the marina's head, I made the inaugural flush. I was overjoyed that everything worked just fine. After this, I used it a couple of more times, and then . . . and then . . . things started going badly.
It was that damn joker valve. Seawater and . . . other things . . . were leaking out of it steadily whenever I flushed the toilet. What could have gone wrong? The problem, as I discovered from my reading of old threads on various online sailing forums, was that I had tightened down the screws on the plastic flanges surrounding the joker valve too tightly. This apparently had caused the plastic to warp, thus causing the seal around the joker valve to be broken.
I had no choice but to remove the hose that led from the toilet to the holding tank. This created some unpleasant spillage in the area around the toilet.

The joker valve looked perfectly fine after I removed it from the housing and cleaned it up.
There were no obstructions within the neck of the valve.
Some persons said online that once you over-tightened the plastic flange you'd never get a good seal around the joker valve again. Some said they had ordered new flanges, only to warp these new ones.
I decided to try a risky solution that was untried by any before me, at least as far as I could tell.
I applied butyl tape to the flange of the joker valve. I figured that this would compensate for any warp that existed in the flange of the plastic housing.
I also applied it to the other side of the joker valve flange. I considered this risky due to the incredibly sticky nature of the butyl tape itself. I was worried that it would create a clog in the system.
I put everything back together.
The plastic flange appeared to cause the butyl tape to squeeze outward, sort of like deck hardware causes butyl tape to squeeze outward when you tighten down the screws.
Here's a close up.
Fortunately, this solution to the problem was a sound one. From this point forward there was never another leak, and the butyl tape created no clogs.
As far as the head itself was concerned, I next applied labels to the different components. As I said in my previous posting, it's not very much help to the Admiral or anyone else if I'm the only one who knows how all of this stuff works. On the lid of the toilet I added the following injunction: "Attention Males, No Standing Allowed." This was a rule on some of the tall ships on which I had sailed, and I thought it was a good one. It keeps you from banging your head on something while the boat is underway, and it keeps your aim more true. Who wants to clean up unnecessary spills?
I also added several injunctions to the bulkhead, just beneath the toilet paper. Here, not a soul aboard could miss them.
Again, these were rules that I had learned on some of the tall ships on which I had sailed, and I thought they were good ones. I don't care what Raritan says about the PH II being able to handle toilet paper. If you read the directions carefully, it can only handle a minuscule amount. Why risk it? Unless, of course, you don't mind assuming the job title of Joker Valve Specialist.
There were several other things that I added to the head as time went along. First, was the coat hook. Like the door handles, this was solid brass, and it was an item that I had found at my local hardware store. I had earlier installed three of these hooks on the exterior of the door and found them to be very useful. There were times, however, when I preferred to hang a jacket on the inside of the door, just to keep it out of the way. This hook served that purpose. The porthole style mirror was something that a previous owner had added at some point. This was a keeper. If you needed to use it, you simply sat on the closed lid of the porcelain throne, as if it were a chair.
I also added a thermometer. I also found this at my local hardware store. The base of the thermometer was painted aluminum, so I did not have to worry about rust. Why the thermometer? I found it to be useful in the monitoring of the temperature differences between the head and the main salon. By securing the door of the head in an open position, I could equalize the temperatures.
Speaking of temperature differences . . . the main culprit certainly had to be the forward hatch, which was located directly above the head. The bronze colored Lexan that I had installed on the hatch when I rebuilt it did little to deflect the sun's rays. Therefore, I temporarily installed a piece of cotton fabric - cut from an old sheet - as a shade of sorts. This made a big difference, and it also protected the varnish from UV rays.
Later, I gave the hatch a more professional touch by sewing a Sunbrella cover for it.

Yes, all of the time, effort, and money that I expended for this project were worthwhile. The quality holding tank, the quality hose, and the dual-vent system for the holding tank meant that this head would remain pleasant, despite frequent use. The air conditioner made the interior of this boat almost like a hotel room, and the Admiral and I considered this head to be first class.
This ends this article on my replumbing and refitting of the head of Oystercatcher, my Ericson 25.

Plumbing, Head, Part 7, Installation of Toilet, Seacocks, Manual Pump, Strainer, and Starboard Vent Valve

The toilet and other components of the new plumbing system, installed and ready for the hoses
Having accomplished many preliminary steps, I could now install the toilet and other components of the new plumbing system. How I did this on Oystercatcher, my Ericson 25, is the subject of this posting.
I wanted to install the toilet first, but I needed to do a few things before I could carry this out.
For one thing, I needed to check the mounting holes for the toilet. Back in 1975 when Ericson had manufactured this boat, they had installed a block of wood underneath the fiberglass shelf in the head. I knew there was wood under the shelf, because the original, coarse-threaded, square-headed wood screws that held the original toilet in place would have small grains of wood on them whenever I removed the screws from the platform (remember that I had reinstalled the old toilet a number of times in my replumbing of the head). The screws also made a distinctive squeaking sound whenever I turned them. I could only assume that this wood was teak, since it had held up this well for this long.
Nevertheless, I didn't want to give it any opportunities to begin to fail now. Therefore, I beveled the original holes with a countersink bit. My plan was to install the new toilet with butyl tape on the mounting legs. This tape would form a gasket of sorts around the screws when I tightened them down on the legs.
Long before this time I had installed the new bronze through-hulls and the mahogany backing plates and bronze flanges that supported the through-hulls. Now I could install the bronze seacocks. I started with the waste discharge through-hull. I wrapped Teflon tape around the threads of the flange, and then I screwed on the seacock. Notice that I removed the handle of the seacock prior to my installation of bronze valve.
If I had not been able to remove the handle, then I never would have been able to install the seacock. The mahogany bulkhead would have been an obstruction. I had thought through all of this in advance. I had also thought through the issue of the handle itself. This Groco brand seacock was designed to give the user some flexibility in terms of the positioning of the handle for the opening and closing of the seacock, where either pushing it away from you or pulling it toward you would open it. This was a good thing, especially for tight spaces.
There was, though, the issue of the orientation of the valve mechanism to which the handle was joined. In the pictures above and below, the valve mechanism is facing the bulkhead. I have not yet fully seated the seacock into position on the flange. I took this picture for illustrative purposes. If this were the fully seated position of the seacock, then there would be no way for you to install the handle, and there would be no way for you to use the seacock. Why? Because the bulkhead would be in the way. The valve mechanism needed to be facing the other direction in its fully seated position. How did I ensure that this would happen? Forethought. Back when I had installed the flange, I had fully dry-fitted the seacock to ensure that the flange itself was oriented correctly.This was the only way that I could have figured this out in advance.
One other thing . . . notice that on top of the seacock I have installed a bronze tailpiece with Teflon tape. I had purchased a straight tailpiece (as opposed to a right-angle one) because I had determined that this one would provide the fairer lead for the hose.
After I had installed this seacock, I moved on to the other one - the one that would supply seawater for the flushing of the toilet. For some reason I did not take any pictures of my installation of it. The picture, below, however, from an earlier stage in this project, gives you some idea of what I had to work with. Notice that the tailpiece for this seacock is right-angled. I had determined in advance that this would provide the fairer lead for the hose that would join it than would a straight tailpiece. Because of this right-angle piece, the installation of this seacock required even more forethought than than the previous one. Not only did I have to take into account the angle of the handle, but also the angle of this tailpiece. I have a better picture of the final installation later in this posting.
Now I could focus on the toilet. This Raritan PH II came out of the box preassembled, for the most part. It too had a right-angle piece that I had to take into consideration. Below, we see that this plastic tailpiece is oriented downward. I needed to turn it around so that it worked for my set-up. I can't imagine how the downward orientation would work for anyone's set-up, but I guess that's beside the point.
My re-orientation of the tailpiece enabled me to get a glimpse of that all-important joker-valve. This is that part of the toilet that gets so much discussion on all those online forums. Everything that you put into that toilet has to go through that narrow slit. The joker valve is the gatekeeper - an easily disgruntled one, I might add, who'll walk off the job at a moment's notice, if you don't respect him. Speaking of job positions, have you every heard of this one - Joker Valve Specialist? That's the position you fill when the gatekeeper quits.
Ah, yes, so funny to imagine the Joker Valve Specialist at work. It's not so funny, though, when you're the first one called upon to fill that position . . . because of your own dumb mistake. Forethought . . . oh, how I elevated that virtue to the stars. Now the tables would be turned. Why didn't I read more on those online forums about the tightening of the plastic flange? I should have. I instinctively dogged down the nuts on this flange. We'll discuss the consequences of my actions in the final posting of this article.
I mentioned that I would install this toilet with butyl tape, right? Well, here it is.
Before I set the toilet into place, I needed to install the toilet seat lid.
Raritan Engineering in Millville, New Jersey might have made the porcelain toilet, but they didn't make the toilet seat lid. That honor goes to Bemis Manufacturing in Sheboygan Falls, Wisconsin.
This was the Raritan PH II, Marine Style (not the Household Style, which was too big for the space). I had purchased this toilet from West Marine, back when they did real price-matching, not like the price-matching they do now in 2016 where they have a million different restrictions. They matched the price that Defender was offering during their annual spring sales event. That made it worth my while to buy it locally from the normally high-priced West Marine. Ever since they changed their price-matching policy, I've given most of my business to Defender and depended upon West Marine for little, last-minute things. This just makes the most economic sense to me, the consumer.
This Bemis lid joined the Raritan bowl in the same fashion that household lids join household bowls. It was an easy installation.
The hose that you see pictured above and blow was preinstalled. This was for the seawater that would provide the flushing action for the bowl.
See the pump housing on the right? By working the pump up and down by hand you draw seawater up through the seacock, up through the anti-siphon loop, down through the seawater strainer, and then down into the manual pump.
Speaking of seawater strainers . . . now it was time for me to install mine in the head. The Groco brand plastic strainer came with an aluminum mounting rack, but it did not come with any fittings. I had purchased the black Marelon right-angle fittings separately.
For the time being, I installed the fittings loosely, with a downward orientation. Later, when I installed the hoses, I would orient them correctly. The correctness of anyone's orientation depends upon his set-up. For mine, one would point upwards, the other down.
Now let's take a look at the orientation of the seawater seacock handle and the right-angle tailpiece. Everything turned out as I had planned when I installed the flange long before this time. When I fully screwed the seacock into position on the flange, the valve mechanism ended up adjacent to the fiberglass bulkhead. This allowed me to install the handle as you see pictured. To me, this was the most natural position for the handle. The user of the toilet could reach down beside him and push the handle downward to open the seacock. Then, he could reach down and pull the handle upward to close it. As far as the orientation of the tailpiece was concerned, it too ended up being close to what I had planned. This one was more difficult to plan in advance. As I recall, I wrapped the threads several different times to different thicknesses to get the tailpiece to end up where I wanted it to be.
Below, we see a picture of the waste outlet seacock as it appeared after I had installed the toilet. There was just enough room for the handle. Note that the tailpiece for the head is now oriented 45 degrees to the left. Yes, this orientation is possible on the Raritan PH II tailpiece. This ended up being necessary, not only for the sake of the hose that I would soon install, but also because I needed the room for the seacock handle. Yes, the handle was oriented, for the most part, where I had planned in advance for it to be, but it was not exactly where I had wanted it. I had wanted it to be in the the 10 o'clock position, not the 7 o'clock. As it turned out, the 10 o'clock was actually better for the reason I just described. Just as is the case when sailing, the ability to adapt to changing conditions is a must.
The last thing I needed to do for this part of the project was to install the holding tank vent valve on the hull of the head. I used flat head screws in counter-sunk holes so that the heads of the screws would not interfere with anything.
Now I needed to install all the hoses that I had previously pre-cut for this new plumbing system. That's the subject of my next posting. That part of the project, just like this one, would require some adaptation to changing, real-world conditions.
This ends this posting on how I installed the toilet and other components of the new head for Oystercatcher, my Ericson 25.
