Electric Bilge Pump

[ful-rac]

Hi Jim, I appreciate your feedback and your suggestions, I highly respect your opinion. The check valve I am using is not the traditional ball and spring type setup, if you take it apart it reminds me of a heart valve. I believe it's made out of some sort of silicone rubber type material, nothing to rust or get stuck. Raising the bottom hose is a great idea, like you said it would force the water to go uphill makes sense. As far as water splashing and getting into the thru hull fitting....very minimal almost none in most situations. The check valve seems to work very well, it's not completely water tight, if I spray with water it will let in a few drops but I'm not going to worry about that.

Fair enough..
I wondered if it was a ball of flap type check valve. That pretty much get's rid of my concerns. I would still run fresh water through it after each trip.. just for the pump.

I actually put bilge pump on my original plastic kayak a FND. Instead of running the outlet out the side I ran it to the rear well and then added a cap that I could open or close too keep water out

Good stuff.

For me it's interesting to watch the kayaks as they become more like boats each year, at least in the manner people are rigging them.

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.
