Re: Bilge Pumps Won't Suck
I had a bilge pump that wouldn't seem to "prime" and start sucking unless I waggled it about.
I replaced it with a new bigger one and seem to have the same problem. Even when there are a few inches, well above the impeller, it won't prime and suck.
The height to the hull outlet seems ok. Any ideas?
Get rid of the in-line check valve, which will cause exactly what you are seeing....
