galley sink drain General Forum Forums

OK, all you guys were not helpful with this so I figured it out on my own. I still don't know about the sink going straight down to the through hull without a vacuum break but that's the way the PO had done it so I'm going with that. I figured I needed to do everything that had anything to do with the (cavernous) space below the galley sink before I installed the sink and that turned into a complete plumbing job as the last one was an abomination. I swear the PO must have gotten really high or drunk before they started any boat projects. 

I'm using a push-fit system with 5/8" OD plastic pipe and push fit fittings from Freshwater Systems. It could not be easier! The water heater was an old Roritan (whatever) which appeared to have been pretty consistently leaking so that was replaced with an Isotherm 8 gallon (stainless inside, poly outside after much research. Fit just right in that spot.

I'll have about 4 days and $800 into the whole job. Turns out the Flojet pump was built to not need an accumulator tank but the system got a tank anyway. I've even stuck a shower into the starboard side of the cockpit footwell which is right over the hot/cold pipes and is intended, more than anything, to keep the first mate happy over a longer period of time. I figure the more creature comforts I can afford her, the more she'll be able to consider the boat a home away from home.

I still need someone to tell me if I can drain the shower in the head into the raw water intake for the head which is right there. I asked that a long time ago and am just getting to that project. When I first started digging into the bilge after buying the boat I found that the shower was led to the deep bilge under the galley sink which seemed like a guaranteed stinky mess. 

Thanks!

The guys in the yard who have been watching the project are starting to give me crap that all I do is work on the boat, I never take her out. Just getting the main genny winches bolted down which should be the last of the running rigging then I might screw up the courage to take her out. Winter time is our sailing time but getting a 16 ton Hippo in and out of a tight slip next to a lot of shiny fiberglass has me sweating just thinking about it. The easterlies want to turn her bow in the wrong direction and while I had a great system on my little 25 footer, this is a whole new deal.

Wish me luck

Not to worry! The pressurized fresh hot and cold water are all push fittings but the through hulls are all double clamped hoses. I am interested to know if everyone else's galley sink goes straight down from the bottom of the sink to the through hull. I don't have a good feel for where the water level is so I don't know how high above it the sink drain is but if it isn't high enough, and I don't know what high enough is, above the water line I would think a high loop would be advisable. There is not one now.

I'm nervous about all my through hulls until I change them out which hopefully won't be until next summer when we haul again. 

I think it's portlights next as the water should be done and functioning soon.

Fingers crossed.
