Other Bilge pumps Home Made ish check valve

[Yashoo]

I think I looked hard enough and didn't see 3/4" check valves anywhere for bilge pump exits. I know you can loop up and over, but it would be nice to keep hoses short and direct if possible for engine bay cleanliness. I tried some plumbing places and only found heavy brass with strong springs on the ball. These would also need barb adapters which is too much adapting. Also looked at sump, irrigation, and other PVC check valve options, however they were all large, like 1 1/4" and up. So I came accross this idea. Let me know your opinions . Please be kind.

At my local automotive store. (for local canadians, Canadian Tire) they have these things as seen on TV in pic 1. It's the cheesy shake to start siphoning fuel out a car, lawnmower, power sport machine , etc. hose.

not for salt water use!!

Its perfect on one side to use the existing hose to attached to your bilge outlet barb. The other side has a lip and I just sanded/grinded it down to fit the 3/4 " bilge hose and then I sleeved over a bit of clear heat shrink tube first . Then sleeved over the 3/4" plastic bilge hose . This gives a non slippery surface for the short overlap of hose to not slip off easily. Clamped it up and installed. In my case thats 2- 3/4" holes that wont be taking on water in my KRASH hull.

I am trying this idea with running 2 bilge pumps as well as my versiplug. I have the one bilge pump located in the regular spot near the mid shaft. and I installed a mini bilge pump down the built in tunnel on the port side of the rear of the hull . This is where the old scupper / new versiplug is installed. For me, this pump will be an alarm indicating when the versiplug is leaking or not working. We'll see.

Sounds interesting,you’re just gonna have to try it out.May be a good solution

I admire your creativity! I had the same concern with my SJ. The previous owner put the bilge outlet way too low and it would frequently suck in water. With that said, you have a couple options. Rule actually does make a 3/4" check valve. Here's a pic of it. These actually fit really nicely inside the 3/4" outlets we use and then you just put the hose on like normal. Super clean install. Here is one place you can buy them. https://www.thechandleryonline.com/product_info.php?products_id=10767

Another option is to just buy a newer style Rule bilge pump. The newer style ones, like in the pic below actually have that exact check valve built into the outlet of the bilge pump. So you wouldn't need to worry about putting one somewhere else in the line. The only downsides to the newer style is that the hose barb potion sticks out a little bit further than the older style pumps.

I could be mistaken, but I thought they changed the design of the new Rule to have a built in check valve. If you look at the new ones the side outlet is different. “Our next generation of Rule pumps include check valves and to do this, we've created hidden air vent to prevent airlocking. Under each strainer tab there is a small hole that vents any air trapped in the pump housing preventing airlocks...and that's how we do it.”

Thanks guys. Definitely some good solutions here. Maybe this will help someone else not waste the time I already did. However was FUN.


Some comments:

The Jabsco is large 4" x 2" x 2" footprint and expensive (can almost buy the new style Rule pump with built in check valve for 30% more $)

The external Rule check valve looks perfect and cost/size is very good for someone not wanting to buy a new pump.

Definitely, I’ll test out this custom job first, just for curiosity in the spring, and when my bilge pump goes, a new Rule pump with Inc. check valve goes in would be the cleanest.

Some of the sit downs came with a check valve as well. The outlet size is a bit too small to adapt to 3/4” bilge line but it might work inline with stock rubber hoses as a retrofit.

Thank OCD Solutions. Thats a good idea as well.
