Re: Head's raw water intake not working.
I have a similar but different problem on my Jabsco head...
I "loose" the prime on the RW intake and have to pull the line to bowl off, put my finger over the pump hole and pull release, pull release to get water up to pump...then it will work fine for awhile...till it looses prime again...
Sounds like this "check valve" is leaking back, but not so sure I have one in line from the RW intake thru hull..
When did you service the pump
