Potable Water Systems

Galley Water Systems

With the countertop installed and covered in Formica, I ordered a deep sink.  The basin is 13" x 17" and is over 9" deep.  When the sink arrived, I laid out for the cutout, applied masking tape (to prevent splintering and abrasion damage to the laminate) and cut out the hole,  The sink is now loosely in place, awaiting final plumbing before attaching it permanently with the supplied brackets and caulk.

At some point after the sink had been installed, but before the boat was launched, I awoke in the middle of the night with a thought:  would the new sink, being as deep as it is, be above the waterline of the boat?  It would be close, to be sure.  All I could do was wait and find out.

Of course, the sink ended up being too deep for its location.  The bottom of the sink ended up being a couple inches below the waterline of the boat, which, of course, means that there was always a couple inches of water in the bowl.  This was unacceptable, of course.  One reason for this is because I lowered the countertop in the galley area by several inches when I rebuilt.  This was to provide more clear space above the countertop where it extends beneath the cockpit bridgedeck; before, there was a scant few inches, far to tight to utilize the space for any real storage, or even to use the space beneath the countertop effectively since there was no real way to access it from the top.

Now I was faced with a problem:  I had to replace the sink.  I was not pleased with this development, since I was looking forward to the deep sink for washing dishes, storing things during the day while sailing, etc.  Now I had to find a sink with the same flange dimensions, but with a bowl no deeper than 5".  This proved to be difficult!  I searched low and high on the Internet and finally found what I needed at The Plumbing Store, with one minor exception:  the flange had two holes cut out for faucet installation.  I had already installed my fresh and salt water taps through the countertop, so this meant that the holes in the sink flange were redundant.  Oh well...for now, I'll leave it be and address the situation more permanently in the future.  I may try and install the two taps through those flange holes, and then patch the holes in the countertop through which they are currently installed.

Removing the old sink was a little bit of a trick, as the polysulfide bedding I used to secure it was holding fast.  I finally got it out, and cleaned up the countertop in preparation for the new sink.   Then, I installed the new sink in a bed of polysulfide and weighted it down all around to hold it in place while the adhesive cured.   Then, it was a matter of reattaching my drain hose, and the installation was complete.  The new sink functions well; after a season of use, I moved the faucets so that they came up through the holes in the sink flange, which broadened their reach and made things function much better.

At the start of the second season with the new sink, a new problem developed, in part because the boat was more heavily loaded and therefore sitting lower in the water:  the sink did not drain properly.  At rest, the water level in the drain hose (equal to the level of the waterline outside) was just below the bottom of the sink.  Weight in the cockpit would cause water to flow into even the shallower sink, and if the seacock was not closed, water would flood into the sink when sailing on port tack.  Dishwater would stagnate in the sink and leave a disgusting residue when it finally drained overnight.  Clearly, a solution was needed.

Update:  2008

After dealing with a variety of ultimately unsuitable modifications to the galley sink setup, I decided to completely reconfigure the system, reverting to a deep sink and locating a new sump chamber in the bilge, far removed from the sink itself so as to address several issues with the "third try's a charm" semi-original setup that I installed in 2003.

We are, for the moment at least, keeping things simple by installing only foot manual pumps for water.  In addition, manual pumps help conserve water on board, an important consideration with only 23 gallons in the forward tank.  I installed two Whale gusher foot pumps in the space beneath the stove, hidden behind the settee cabinetry.  There is access for future service by removing the bottom panel of the stove enclosure, which is possible even with the stove installed.  The foot pedals protrude into the cabin for use.    To cut the slots through the cabinets for the pedals, I first cut 5/8" holes top and bottom with a Forstner bit, then connected the holes with my jig saw.  The pumps were installed from the inside with screws through the holes provided; access was tight because of the curvature of the hull, so I had to use a hand screwdriver.  (The horror...the horror!)  One pump is for fresh water, the other for a salt water spigot.

Head Water Systems

I also installed a foot pump in the head, in the new vanity, using the same method described above.  I made a mistake, and placed it a little too far aft so that the seacock handle hits the pump when I tried to close it.  Oops!  To fix this, I removed the handle and bent the end 90 degrees; this enables the handle to clear the pump body, yet still makes it easy to turn.

I installed the spigot at the head sink the same way as described above.  Then, I connected more hoses as necessary, running from the tank to a T fitting in the line, then to the head pump and beyond to the galley pump.  I cleaned the water tank, filled it, and we were ready to go.

Rather than install a complicated and water-hungry shower and/or electric pump, we chose to stay simple.  For a shower, we use a regular garden sprayer--the kind with a tank that you pump up for pressure.   Believe it or not, the very fine spray from this works great as a shower, or to rinse off after a swim in salt water--and it uses very little water.  For privacy, we have a Sunshower enclosure that we can hang from the boom.

During the course of installing the new holding tank and plumbing, I had to make a small modification to the water tank.  The Triton, as delivered, did not have a deck fill pipe for the water tank.  This is inconvenient.  Last year, I filled the tank by running a hose into the large inspection port in the tank that I installed.  Less than perfect.  My sanitation plans call for a manual waste pump to be located just forward of the holding tank, on a platform over the existing water tank.  This will make access to the tank even less convenient (though still possible if necessary), so I thought I would take a moment and address the issue.  I discovered that the 1-1/2" PVC threaded fittings that came with my holding tank fit perfectly into the threads of a standard waste deck pipe.  So, I drilled a hole in the tank and installed one of these in a thick bed of 3M 101, holding it in place with screws.  Later, I installed  a simple straight nipple, one end threaded (1-1/2") and the other end barbed, and secured a length of flexible bilge pump hose to it with a hose clamp.  I ran the hose forward beneath the vee berth into the chain locker, then up to a new deck fitting.  Voila!  A new remote water tank fill.
