I finished making all the plumbing connections for the cabins.
99% of the connections are under the sole in the bathroom. This space has turned into a busy area as it has passing through it four fill lines for the water tanks, the shower/sink pump sump, the water supply lines for the two sinks, the drain lines for the two sinks, the drain line for the shower, the "Y" valve for directing the sump discharge, the transport lines for the sump discharge, the 1 1/2" transport line for
a possible future macerating type toilet, and the wiring for the sump. I made a valid attempt at keeping this space orderly, and if I had used some more fittings on the drain and discharge lines, I could have kept things really tight but I instead opted for less fittings and more flexible pipe.I'm going to build the shower stall out of tile. Since I was working in this area, I decided to install the backer board for the tile, and
the shower pan. Before I installed the backer board, I glued a closed cell foam gasket to the flange of the port light to stop condensation. Once the tile is installed along with the port light, I'll detail the gasket more so it will make more sense to anyone reading. As per a request from the three woman in the house, I built a ledge in the shower stall for a place to prop up a leg.After making all the connections, I ran the shower sump to verify the flow rate. The shower sump is not going to have enough ass to move the shower water to my proposed gray water tank area ( the rear of the boat). I'm going to have to find another area for my gray water holding tank. The best place for this tank is going to be close to the overboard discharge point in the forward cabins. The tank will probably end up in the "V" up against the crash bulkhead @ station #1. I think I'll be able to fit a 40 gallon tank. My other choice is going to be under one of the kids bunks. The problem with going under the bunk, is that I'll eliminate a much needed storage cabinet.
I'm ready to sheath the bathroom, the dressing room/hallway, and part of the kids cabin. I'm going to have to hold off on sheathing the rest of the cabin until I get the gray water
tank installed.I'm going to use a composting toilet, but just in cast it does not perform, I installed a transport line for a future macerating style toilet. I
plumbed this in with 1 1/2" sch. for pipe, using pressure fittings. I wanted to stay away from flexible pipe for this application so I had to use a few 45 degree fittings to get the pipe squared back up with the framing as it enters the bathroom area. This 1 1/2" line goes to the rear of the boat where I'll have a black water tank. The folks at Raritan assure me that their toilets can handle the lift and length of pipe just fine.
Hi, I notice that you have a through-hull for the sink's gray water. Assuming you have done this for all 3 bedroom sinks as well as the kitchen sink that makes for 4 possibly superfluous through-hulls.
ReplyDeleteAs each through-hull is a potential problem I wonder why you went down that route. I would have simply routed everything to your holding tank. That would have had the added benefit of eliminating the possibility of getting a fine for discharging gray water where it's prohibited due to human error.
By routing everything to the holding tank you simply everything, don't run that risk and eliminate possible problems with the through-hulls.
My main assumption here is that you can pump overboard the holding tank in the same areas where you can run the gray water overboard.
What's wrong with my reasoning?
Hi Shtrudel,
ReplyDeleteThe master cabin sink and shower exit the boat via a sump pump. The guest cabin sink exits the boat via the same sump pump or it can gravity flow out the starboard side above the water line. If I"m in a situation where I have to hold the gray water, the guest cabin sink can be diverted to the gray water holing tank. So, in a nut shell, the boat has one through hull fitting ( above the water line) to handle the cabin sinks and showers.
The boat has one through hull fitting below the water line that acts as a sea chest for generator cooling, and a wash down pump. I have a total of 4 available ports on my sea chest manifold, but I doubt I'll use them. The main engine is keel cooled, so no below the water line through hull is needed for the main engine.
I agree with everything you said. Thanks for the observation.

Look in your local parish magazine. Often the plumbers who advertise there live close by - in an emergency someone who is just down the road may well be quicker, cheaper and, more importantly, willing to turn out. Columbus plumber
