I'm replacing the galley sink because it was one of the first things to go in the refit so I'm getting the biggest sink I can find but I'm looking at the drain that goes straight down to a through hull. I would not be surprised but that was changed from something with a vacuum break but someone please tell me if that correct. I'd love to just hook the sink up and call it good because the next thing I have to figure out is the pressurized water system.

Right now it appears the line comes off the pressure side of the freshwater pump and directly into the hot water tank which then, I think, acts as the accumulator for the whole system but since it's apparently hooked up backwards provides only scalding water to every tap in the boat when the engine is running. Can someone please tell me how the system works? are the tanks pressurized by the pump or does the pump suck off the tanks? I could probably figure it out if I spent a Saturday with my head in the bilge but while the wiring is all new and pretty, the plumbing is spaghetti.

Thanks ever so!

Hope to run some running rigging through deck organizers and clutches and mount some winches soon so we can actually go sailing since our sailing season is just starting. Woo hoo!

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

Take this with a grain of salt but for a hose or system tied into a through hull I'm not sure I would feel safe with a quick connect push fitting. I might just be a fussy old hen over it but a hose with a double hose clamp or threaded directly together sound a little more resistant to accidental damage.

I once found out a backing plate on that same through hull was rotten, not 2 days after putting back in from a annual haul out by grabing the plumbing to brace myself while leaning under there to check on the fresh water pump that is located under the cabinet floor under the sink in my boat. The hose and everything shifted a few inches to the side and moved the through hull fitting sideways at an angle to the hull. Water started pouring in around between the hull and fitting. Talk about a hollow sick to your stomach feeling. I CAREFULLY, moved the hose back straight and therefore the through hull back straight and the water flow slowed to a trickle. Then called haul out place and was headed back that way within 30 minutes. New through hull is bedded with fiberglass backing plate.

Scary thing watching water pour into your boat from an under water fitting. I go overboard on anything attached to an underwater opening in my hull now.

Just picture in your head how yours is setup now, and think about bouncing around in rough seas and for some reason someone needs to access where it is and in bouncing around reaches out and braces themselves on that fitting, pipe or hose and think how comfortable you are with someones 150 to 200 lbs of body weight pushing or pulling on it if they lose their balance or if they just think its okay to use it as a support/brace. It only takes one moment of carelessness by you or even worse someone else that doesn't know they shouldn't do that and that it might be dangerous to ruin a great day on the water. Or make a bad day worse! :)

as I said above i am always wondering what would happen worse case!

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.

Hi Rick...

 

Sorry, Ive been busy and haven't visited lately...

 

Galley sink

Yes, my galley sink drains tie together ( double sink) under the starboard one, and then the hose drops straight down to a thru-hull fitting.

I believe this to be a factory setup.  1" line.

 

I've also added a "Y" directly under the sink, and use it to dump a shower sump pump in, as well as a secondary bilge pump. I located the shower sump pump under the sole, just forward of the fuel tank ( pretty much under the sink, admidships)

 

Hope that helps

Bob

The sink should be above the waterline on heel and no worries of water coming in. If your still worried you could put a valve inline on the hose to the through hull that you can reach without having to take everything from under the sink to get to the through hull itself.

 

SoloBob,

 

We had a drain from the shower that went back to a aft through hull or bilge? can't remember which now. It was a major disaster on a regular basis. There was a pump on the line to help and it kept getting clogged up. Actually there was a filter in front of the pump and it was what would constantly clog. Finally put bilge box with integrated pump just forward of the shower/head under and to the side of the forward hatch in the   vberth sole. hose went from 15 to 20 ft long to about 2.5 ft long. Just a gravity drop from shower floor to bilge box. Also went from about 1/2 or 3/4 inch to 1 inch in size. Then we sealed the anchor locker from the rest of the boat and tied a 1 1/4 inch hose from there to the same sump/bilge box. Also at that time we still had a heat pump ac/heater on the boat and we ran the condensate line from it to the bilge box.  Then a 3/4 inch line up to a above waterline through hull in the starboard closet in the vberth. with a anti-siphon valve installed in the top of the closet. And a one way valve just outside the bilge box on the 3/4 inch line to keep water from back flowing from the near side of anti siphon setup. It Has worked for years without maintenance or effort.
