Need advice for a washdown pump installation

I am going to install an anchor washdown pump with a hose outlet in the anchor locker of my 40.5. I am interested if anyone out there has done this themselves or if they have a pump installed. I would like to know: 1) Where to locate the pump? Servicing requires a convienent location; I am considering installation in the keel area just under the floor or under the vee berth. 2) Water inlet? I would like to use an existing thru-hull such as for the A/C in the keel or a tee-off from the forward head inlet. 3) If I use the A/C thru-hull, is there a easy route for the outlet hose to the anchor locker? Any tips for this installation project?

washdown

I put one on my h410. I have the hose connection mounted above the rear transom locker. I used the aft head thru hull. I mounted the pump in the shaft area under the aft stateroom bunk. The hose run was an easy one to the transom from here. Doing the electrical work was the biggest pain. Know that's not exactly what your looking for but it was an easy install here. I use it more for deck and cockpit washdown, especially spring pine pollen in New England. Bryce S/V Spellbinder

This is what I did...

I'll echo Bryce's post. I tee'd off of the head through-hull, I also installed an anti-syphon on the hose leading to the head for that problem. I used an old fresh water pump that I had replaced and rebuilt. Ran the outlet hose to the cockpit with a faucet head on it. It's very conveinent for washing the cockpit and the boat with a longer hose, and it saves on the freshwater usage at our docks! Good Luck and Good Sailing!

I did it too, (sounds like a song)

I have a 40.5, and did a really neat install as I'm a little obsessive in that regard. First of all, I installed an extra through hull fitting with its own seacock valve. Oh, stop moaning all you guys out there, there's a good reason for it. Basically, when I'm not using the pump, I shut the seacock off, so I am not risking a major hull leak. You see, the proper installation is to use a fresh water strainer before the pump, and these guys can and do leak. Furthermore, the pump needs to be winterized properly, which means disconnecting the input and output hoses. If you just T off an existing through hull, you can't do that. I installed the through hull in the midships locker under the aft berth, and the inline strainer in the same locker on the starboard wall. The pump is actually mounted on the aft wall of this locker, but on the other side of the wall; e.g in already dead storage space. You must run a #14 minumum wire run from the panel, on a dedicated breaker. The pump has a nasty inrush, so this is required. Next, I installed a flange mount Perko male hose unit on the port rear transon locker wall. This allows for easy access. A good tip is to buy Garneda roll up hose, as this will reach anywhere on the boat from there. In other words, don't bother putting the fitting in the anchor locker, just run a hose from the cockpit. I also have a 10 foot section of hose availabe for quick cockpit spray down. My kids spill cokes at the rate of 6 per hour. Good luck Art

wash down

Art I guess I cringe at the thought of putting more holes in the bottom of a perfectly good hull. I forgot to mention I placed a Y-valve before the water strainer and attached an additional hose and ran it to the bilge. The high volum pump is an exceptional emergency bilge pump.

Great Idea Bryce!

I plan on a wash down pump using the through hull/seacock for the A/C. It is installed on the port side of the keel. It already has a strainer. I'll add a Y-valve. I should never need A/C during a wash down. I too, will use it as an emergency bilge pump by installing a second Y-valve with a pickup hose in the bilge. Cheaper than another pump. I will route the discharge to the anchor locker since I already have a fresh water outlet at the transome.

Just for the Anchor?

I notice the previous posts use the pump installation for more than the anchor locker and that's fantastic, but if you just want something to spray off the contents of the anchor locker, you can install a high-output manual bilge pump in the area. How you do it is your preference but here's a few options: 1. Permanently mount the pump on bulkhead of anchor locker (may limit ability to pump) 2. Mount pump to anchor locker lid/door (you can pump while door is open if mounted underneath door, or pump while door is closed if mounted through door. Disadvantage is you can't see how clean the anchor and rode is getting and you have to leave room for it when the door closes. 3. Mount the pump to a plate that slides into another plate permanently mounted to the bow pulpit. Disadvantage: You have to move the pump to get to the anchor/rode. 4. Mount pump with foot actuation aft of anchor locker. Disadvantage: Goes through the foredeck and has potential for leaks and you'd want to build a box to cover the pump on the inside of the v-berth. 5. Permanently mount pump to bow pulpit. Disadvantage: looks like hell Requirements: Have long enough hose to reach the water. (Disadvantage: Occassionally difficult to prime, but it does work.) Major Advantages: No electrical power required, no thru-hull required, no electrical pump required, manual bilge pumps are cheaper and easy to service and rebuild, no major hoses required other than intake and short gusher output, no faucet required, no in-hull hose run, will still pump water onto the deck. (With a long-enough hose and a manual pumping crew member, you can still reach the whole boat.) Less weight??? Less cost, less installation, longer life???, more "nautical" :) Any comments?

Thanks for the ideas

Thanks to all for your ideas. My primary desire is for an anchor washdown, so an outlet in the anchor locker is my best choice. I can leave a self-coiling 10' hose attached at all times and it won't be in the way. If I need to wash the entire boat, I can connect a longer hose that I carry. I already have a thru-hull in the midship aft cabin locker for my generator, so there is no more room for another one. I already have an A/C thru-hull in the keel area with an existing raw water strainer, and I am going to plan to tap off of that connection. This gives me a filtered supply without a new thru-hull or another strainer. I know that I can easily provide an electrical circuit from the main breaker panel. The only real unknown is what route to use for the hose to the anchor locker from the keel area. Maybe Mickey and I can collaborate on this issue since he is planning on the same installation. Jay: Your solution is unique, but too many disadvantages for me. I want to just pick up a hose and squeeze the handle. Thanks for the thoughts.

Rich, This weekend

I'll will route the hose to the anchor locker from the fwd bilge. I'll post my installation. BTW, for the last 2.5 years I have used one of those extendable boat hook poles that lets you change to a stiff brush to clean the chain and the anchor while it is still in the water. Keeps alot of the mud off the boat and out of the locker. But the wash down should get it all.
