Bilge Pump Emptying into the Cockpit

I was rewiring my boat after smoking a little herb and now whenever I run my bilge pump, the bilge water empties into the cockpit while, at the same time, pushing some of the bilge water out of the boat like it should.

When the bilge pump is turned off, the water slowly drains from the cockpit back into the bilge.

Now get this, my other bilge pump sucks water from my cockpit and empties it into the bilge, but on only one side. I think the other side is clogged or something.

So while one bilge pump sucks, the other one blows. Damn I've been watching too much FAP.

Suggestions?

Unclog the obstruction. There must be at least one.

Between the lines it says your bilge pump and cockpit drains are tee'd together.

Re: bilge pump emptying into the cockpit

As the water flows from the cockpit back to the bilge could you install a little paddle wheel to generate electricity to run the pumps?

We have a small pump which empties into the cockpit so that on passage if there is a leak the crew get wet feet and therefore might spark and do something about it.

However, I don't think you really need them all emptying into the cockpit, how about plumbing them in overboard.

Small wager - there is an infamous prone-to-fail check valve involved???

Pete
Now that makes sense, but I think here his bilge is just T'd into his cockpit drain and there is at least a partial blockage somewhere.
It might just have something to do with his opening sentence though
I like your high water alarm, good thinking.

Only thing check valves are good for is sticking, you know some people want to use those things in fuel systems

can you elaborate a bit? this would be great for me while single handing.

do you have your main bilge going overboard and a small, 2nd, bilge T(ed) into one of the cockpit drains so a small amount of what is in the bilge wets the toes of those in the cockpit (and then self drains from the other cockpit drains?)

how do you prevent the cycle of cockpit water running to the bilge to be pumped back into the cockpit?

liveaboardL... you are taking the wrong drug.

switch to acid you can just pretend u r hallucinating the water in the cockpit OR switch to coke and u will have all the energy you need to bail the cockpit with a bucket OR smoke enough weed that u just stare and giggle.

maybe the solution is to build a hard doger so u can get the whole fishbowl affect going...

Re: bilge pump emptying into the cockpit

Easier to add an audible alarm that sounds when the pump is running. I have one on my big pump that is up higher in the bilge that doesn't turn on unless something is wrong.

Re: bilge pump emptying into the cockpit

I jumped in the river and got some oysters out of the hole when I saw alligator eyes a few feet away. Just as quickly, I jumped in the dinghy and got the rest reaching over the dink. Didn't do the job. Got a high pressure water hose and rammed it into the drain on full blast while turning the hose. That did the job. Still, I think one of my bilge pumps might be wired backwards, so I'm going to make sure it's not sucking water into the boat before go eat some chips and a sandwich.

Duh! A check valve ! (I kid peeps)

Re: bilge pump emptying into the cockpit

Eliminate the T and add a separate overboard discharge, one for the cockpit and one for the bilge pump, complete with a shut off valve at each of the overboard discharges. This is the correct way of doing this.

It's a bad idea to use a check valve for a bilge pump. They can stick remaining open, closed or part way open or add unneeded resistance.

Use a loop to prevent water from flowing backwards through a bilge pump.
