pump pressure

[Poconos]

Vacuum hoses are notorious for leaking and it only takes a pinhole to mess things up. Maybe do a good eyeball inspection for damage and you can try just submerging all of the hose you can to see if the pressure holds.

I once had a similiar problem with vacuming. I had a bad O-ring gasket on the clear top of my pump filter, and it was leaking air. Fixed that and now I get about 9-10psi of vacuming pressure.

thanks for your help!
the hose was the problem

Another easy and cheap fix and a happy ending. Hoses like that I've successfully used vinyl electrical tape if the hose is in generally good condition and got a small cut or something. But if it shows its age then it gets replaced.
