H356 washdown install

[Bob 04 H260]

I am interested in adding a washdown to our anchor locker. I am thinking about T-ing into the AC pickup with a 3-way selector valve, mounting the pump right there and then running the water outlet hose to the anchor locker using 3/4" PVC reinforced hose.
Have any 356 owners done this job ? was it possible to run the hose forward through the bilge ? any advice ?
thanks, Bob

washdown

I teed into the seawater input from toilet and used plastic pipe just like what hunter used for water and found it to be very good and easy to run along the port side of the boat with the wash down pump right in where all my thruhulls are at bottom steps and put the switch under the nav station and also ran a hook up at the stern also.
Sorry can't show photo's are home hard drive and I am up north traveling
around.

thanks Nick, just the type of thing I was looking for, running a second wash down to the stern is a good idea, I had not considered that. I will look at the water lines Hunter used. I thought the flexible PVC would be easier to run.

thanks, Bob

Good idea, but....

I like your concept. The only suggestion I could make is that the pump should be the kind that shuts off at a predetermined pressure, like the fresh water supply pump. The tubing to the anchor locker should terminate inside the locker in a quick disconnect fitting. That way you can just turn on the pump and take your time to get topsides, open the locker, and when you are ready for washing down the anchor chain or deck just attach the hose and nozzle to the quick disconnect and voila!-- pressurized water. Just as easy to disconnect, all in reverse. Keep in mind that the pump you need is one that is specifically designed for washdown, as that requires much higher pressure than the usual 40 psi of the water system.

Ivan, thanks for the advice. I intended to use the 5 gal/min, 70 psi, Jabsco wash down pump. I can buy it for $183 locally much cheaper than WM, http://www.thechandleryonline.com/product_info.php?products_id=7088

The quick connect seems over priced at $72 but I'll include one of those as well.

Looking at other sites it seems most suggest using the head pick-up for the water supply as Nick did. They also suggest two brass check valves, one in each line instead of the 3 way valve I was considering.

It might be a good idea to plumb it so it could be used as a back up bilge pump in case of a problem .....

I have T's on all my other thru-hulls so I could supply my engine and generator cooling water from my bilge if needed in an emergency. It also makes it easier to flush the engines with fresh water when needed. I'll probably want to flush this wash down pump as well with fresh water when the boat is hauled for summer storage.

thanks again, Bob

Bob: quick disconnect.

A quick disconnect, male and female, can be bought at Home Depot or other hardware store for under 10 dollars. They are rated for garden hose use, so will easily withstand 100 psi pressure. Some have check valve built in, so that you don't need to shut down the pump immediately when disconnecting.

Do consider a stern outlet too. I have both and we use for the anchor, but in fresh water, I use th stern one all the time to clean off the boat in the morning when the cockpit and deck are covered in bugs after a night on the hook. On a hot day, I spray mist water on me to keep cool while sailing. I use coiling hoses and just leave them on the outlet all the time with a good nozzle. I disconnect them in the winter when I winterized after running antifreeze through the entire system.

Mine also taps off the head pick-up.

thanks Jerry, good suggestions.

I just looked at your profile and noticed you also owned a Hunter 260, I think a number of 356 owners have come that route. I guess the 260 showed us how well the overall design works for us. Although when we decided to move up to a bigger boat we looked at them all before buying the H356. It felt the most comfortable for our lifestyle and I also liked being able to ask the factory a question and get an instant answer from someone that really knew what they were talking about.

Hunter 40.5 Anchor Washdown Design

Hi,

I'm hoping to get some good feedback on my design for a new Anchor Washdown setup. My plan is to use the existing thru hull for the head intake, I never use that anyway. Run to a new 60 psi washdown pump which I'll mount in the forward compartment, under the bunk, where the thru hulls are located. The pump comes with a strainer and I'll install a Y-connector in front to let the head intake stay connected to the head just in case. From the strainer to the pump to a flush mount deck fitting located in the anchor well. The flush fitting has a quick connector for a coiled 25' hose and nozzle. The real question is; can I power this new pump from the windlass power? I will use it only when using the anchor so it will have power when I need it and I will install an inline 15 amp fuse to the pump to protect that and the wire. I don't see any issues except exactly where to connect the power, on the windlass or on the control panel/relay panel, I don't know where either of them are yet until I do some investigating.

Any issues, suggestions, or concerns? Thanks in advance.

You may want to consider that the windlass and the pump together may overload the windlass breaker.
Here is a thread with thoughts by others.

Thanks Genesis, I did see that post and saw one response saying he's used the windlass power tap for about 12 years without problems, and others saying it is smarter to use it's own breaker. I think it's better to use the windlass because that is ONLY on, in my boat, when I'm at anchor and I turn it off when underway. That way I won't forget to turn off the pump and in case of a leak I won't flood everything. Additionally, I can't see me using the windlass and the pump simultaneously, I usually crank up the chain, wash it off, crank more, wash, etc. and the pump is pretty small. BUT, I'll certainly have to keep an eye on it and if I do trip things will have to rewire it.

Thanks
