Default Brainstorming: Livewell tubing to rinse deck

Currently my boat has a livewell pump into the hatch that I deem my "fishbox." It's nice to know it's there, but essentially a wasted pump... but even if I used it, I think this might could work.

Seems a pain sometimes to run stretch out the washdown hose to the front of the boat, where it barely reaches, and often kinks... when there's a water source already there, just dying to dump a little rinse water to help the brush rid some blood, poop and slime. Not a full fledge wash and rinse, mind you... just a rinse to make the real washdown easier. (am I the only one who does this?)

Idea 1: Short hose, to go from well "nozzle" to be held by hand to release water to deck.
The current little "valve/nozzle/flow adjuster" in my well is a male 3/4" relatively fine thread. (finer than hardware plumbing fittings.) So I need some kind male 3/4" to tubing adapter. This 3/4" female screws into a larger, probably a 1", so could also use a 1" male threaded to tubed (barbed?)

Idea 2: Have 1-3 nozzles mounted on fish box that sprays onto deck with a push of the livewell pump button. Ideally, the "nozzles" would be flat and mount virtually flush against the front deck "wall", (which happens to be the backside of my fishbox.) Guessing the proper strainer/filter would be the key here, as nozzles like to get stopped up.

I could with relative ease, plumb this same line into a washdown pump.

What you think? See problems? Where to find such fittings?

Storm me.

I've got a 2004 SeaCat that has these two little holes in the base of the console. In the rear are two TH marine manual levers that switch a valve so that water comes out those two holes in the console when the livewell or washdown is on. I will try and take a pic of them in my boat tmrw.

Here is a link to the setup. It comes in a full kit.

Mine setup kind of sucks but I think it's because of my pump. It needs to be replaced. It does work, however. I think it's easier just using a coiled hose.

Interesting. I figured that someone had to have tried to have a built in deck wash somewhere somehow.

Yes, I'd like to see a pic if possible.

The thing about livewell pumps is, like bilge pumps, they are designed to pump high volumes of water, but they don't produce much pressure.

If your goal is getting some water on the deck, your idea would probably work. But if you need to perform tough washdown tasks like cleaning fish blood then there may be a better way. You could install a y valve from your wash down pump and run a hose forward where you instal a second washdown fitting. Of course this would require access to the pump and a way to run the hose below deck.

idea #2 sounds flawed to me. need to direct the water where its needed.

Idea #1 worth a try. I woulf change the livewell fitting to one with pipe threads then adapt it as needed.

Pumps on boats are the biggest PITA. I just pulled a livewell pump out yesterday.

Limp washdown pressure never worked well for me anyway. My sollution is as low tec as you can get but works well. I keep a sturdy pail with heavy rope attached to it on board. When the deck gets bad I scoop up 2-3 gallons of water and blast the deck with it. The volume moves a lot of blood out the scuppers quickly. And it works just fine as a "wet" toilet in emergencys and better than those tiny port a pottys.

I plumbed a tee into my live well pump discharge line and added a pair of valves, one goes to the live well and the other goes to a hose bib bulkhead fitting at the transom. Closing one and opening the other routes the water appropriately. Yes, they are cheap HD PVC valves, but I have a proper seacock where it passes through the hull.

I've since updated the system by adding a second line to the pump input (pump has a built in second inlet port) with a valve that goes to the freshwater tank, and added a shower head / 6' hose teed into the hose bib bulkhead fitting. By manipulating valves I can use the live well pump to run the live well, use a wash down hose / shower with seawater or with freshwater. My freshwater tank is about 8 gallons, and the pump will empty it in about 2 minutes, so I get about 4 gpm flow with the hose extended 5' vertically above the deck - enough for rinsing off after being in the water. If underway, the clamshell pickup would probably boost seawater flow a bit.

As stated above, live well pumps aren't going to give you high pressure, so it is more of a rinse than a wash down. The 800 gph Shurflo Bait Sentry pump I have has a shutoff head of 12 feet which works out to about 5 psi.

thanks for the input guys, and your detailed description of your system, louiefl.

I'm going to try a couple things and report back...
