frogs in bilge pump outlet

[Timeking]

I couldn't figure out why my bilge pump wasn't working, so I took the hose off the pump and squirted water thru only to see a little green head pop out of the outlet fitting. I'm in Florida and there are a zillion mosquitoes where I live and thus a zillion frogs. I have googled all about to see if I could find an outlet fitting with a flap, to no avail. Thus this post. Any ideas?

That's a new one. Do you keep the boat covered?

maybe you need to install a screen over the bilge pump outlet fitting like folks do for their live well pump inlet fitting. JMHO!

Sounds like a good idea to me.

I loop all my bilge hoses verticaly before they exit the boat. Keeps the water from siphoning back in under heavy seas and in your frog case probably would keep them out.

Here is what you are looking for.... Make sure it doesn't seal completely tho as that could trap water in the hose and cause an air lock stopping your pump from working..... you may need to cut a notch in the flap so water in the hose can drain back once the pump turns off.

Thanks for the suggestions, but the outlet hose is 3/4. I'm just going to keep a cork in it and hope I remember to take it out when I'm on the water. That said, it is hard for me to imagine that I'm the first to have this problem. It turned out that there was so much frog poop down in the line that it ruined the bilge pump, and/or the pump simply died of natural causes since it was installed in 1988. Probably a combination of both.

I have quite a bit of tree frogs and regular toads (tons of them little critters when they first hatch ever year) and I have never had any issues with frogs in any tube on all the boats I've owned. Don't know what to tell you other then the screen.

The diameters listed on the descriptions of the valves are NOT the hose diameters, they are the max allowable diameter of the flange of the thru hull fitting on the outside of the boat.... As long as you measure that fitting and it is not bigger than the spec for the valve, it will fit over.

Thanks, smnokeonthewater...I had a bunch of yellow jackets nesting in my bilge hose and blew them out with my air compressor. They kept coming back until I sprayed insecticide in the outlet. I'll get one of these to keep them and anything else that may want to get in.

Would a common plumbing check valve work? They are used in many commercial setting to prevent siphoning.

You don't want any sort of check valve in a bilge pump outlet. It could stick or freeze up. I'd even be leery of a screen over the outlet end. Seems to me that junk from the bilge could lodge there and block it. The flap idea seems best, as long as the flap is larger than the hose outlet.
