Electric Bilge Pump

Where did you get that check valve? I have seen the 3/4" Threaded ones that OEX sells, but that would only mean I have to buy two adapters for the ends in order to connect the hose, I like this one better. Please if you dont mind posting a link to where we can find this check valve, that be great! Thanks in advance bro!

I got the check valve at west marine for about $20 bucks. Here is a link with the model # and picture, it's the 3/4" model.

Now before anybody gets crazy and starts to build this thing I just want to let you know that the biggest problem in this whole system is attaching the pump to the hull. Not many adhesives will stick to polyethylene so you cannot use goop or epoxy, it's not strong enough. I've tried that and they don't work, the pump usually ends up peeling right off the hull. What you need to use is a special glue for poly, I used (3M Scotch-Weld Structural Plastic Adhesive DP-8005). This adhesive is super strong and is permanent. The down side is that once it's on it's on and is not going to come off, so don't screw it up! And in order to use DP-8005 you also have to have a special gun and 10:1 tips Other than that it's pretty simple. So please let me know if you have any questions.

Tony.

Ful-rac,

Where did you get your DP-8005. I have been looking for this in Sad Diego with no luck.

You can get it off amazon.com or at your local grainger, you might pass out when you find out how much the gun, adhesive, plunger and tips cost....especially when you only need just a tiny bit of adhesive...but when you flip that switch and the water starts shoot'n out... it's worth it to me at least...

Thanks. I figure I'll use it for my wet mount box for the FF transducer as well.

Thanks for the link bro! By the way that bilge pump has a built in check valve it it! Read the description in the link below. So having an additional check valve on the hose make it that much more reliable and safer!

No, the pump does not have a built in check valve. Read it again. You must install a check valve, or else you risk taking on water thru the fitting! Don't skip the check valve! You need it.
