Installing a wash down system

I am going to install a wash down system with the hose connector to be in the cockpit somewhere. I was wondering if anyone has done the same and has any good ideas on where to install the thru hull fitting. I'd like it to be easily accessible to the shut off valve. I'm considering under the galley sink, and was considering using the drain thru hull but it's too large and I fear something large may get sucked up there. Thankyou

Hi Mike, you got me thinking, why would you....

want to use raw water for wash down? But then it looks like you're boat is in fresh water? I would tee into an existing intake through hull line rather than cutting a new hole. It sounds like that is your intention? You may not have many intake lines to choose from. I'm not sure about using the one for the engine. If you used the sink drain you could always install a sea strainer to catch any debris. You should be able to find a plastic tee fitting large enough to couple the sink drain hose with a reduced fitting for the wash down line. Just be sure to double clamp all fittings. But then I'm probably preaching to the choir. Terry

Wash down

I have a hot & cold fresh water shower on the stern of my H34, it has a nice door that you can hardly notice, the lines are plumbed to the galley sink. I also have a swim platform on the stern, the shower is great for a quick warm rinse off after a swim. It was not hard to do and works great. The shower line is long enough to rinse down the cockpit area when needed.

I used the AC water inlet

On my 40.5 I used the AC raw water inlet because it already had a strainer and it was in a handy location. I however ran the hose outlet into the anchor locker because that is where I need to do most of my washing of anchor and chain. On your boat an existing inlet thru-hull may not be an option. I guess the sink drain would work if the strainer was in the pump line. As long as you have a good strainer, I wouldn't fear sucking something big up into the drain. You could keep a flexible snake handy to run out the drain if it were a problem.

Use the head intake

I did this on my 37.5 and am in the process of running hose fore and aft to provide washdown points at both ends, so to speak. You might have to search for the correct adapter to take the head intake hose down/up to the size of the washdown pump but you can find it. That was the hardest part of my installation (although, admittedly, my father did all the work.)

Dave, do you have pictures

I will be upgrading the shower on the stern of our H34 and am interested in ideas on a platform. Thanks, Fred

I am heading up to the boat in a few days and will snap a few for you.

Mine is in the anchor locker

and I T-ed off of the head intake. The pump is mounted in the locker above the head. I use it to clean the anchor chain when it comes on board

Mine is next to the head intake

I put the pump behind a strainer and a two way valve. The valve allows the head or the pump to connect to the strainer. All of this is next to the head intake seacock. I ran one 1/2 inch pipe forward to the side of the anchor well. A 90 fitting takes the pipe through the side of the well and is sealed with polysulfide.The anchor hose will be just long enough to reach over the bow and spray the chain and anchor. The white pipe in the picture just below the seacock is the pipe aft. The pipe forward goes through one of the many holes that Hunter drilled when the holding tank was in this area. I also ran a half inch line to the starboard aft lazerette and added a faucet and 35' of hose. The boat is still on the hard so I cannot tell you if I will have any problems. I will post some pictures as soon as I get time.
