i have 75gal salt tank. i am using an under gravel jet system for my return. my sump is below the tank. from the pump i have 5/8" tubing going to a 3/4" pipe over the top and to the bottem were it T's off to 1/2" pipe with 6 jets. i have 2 problems.... 1 i need a bigger pump to push all the way up over and down to the bottom and i need a pump that can give me good preassure at the jets any ideas were to get one and how big it should be (GPM)? keeping in mind i need a lot of preassure not flow rate.
but what i really need is an in line check valve i can put in the return line either 5/8" to install in the tubing or 3/4" with thread i can install in the riser pipe. i have a spring check valve now but it seems to not seal all the way so i would like to get a ball or flapper type valve. any ideas were to get one? o have tried lowes and home depot but to no avail.
just a quick walk through of my set up....
pump to 5/8" tubing to 3/4" pipe up and over to to 1/2" pipe to UGJ
the pipe is pvc rated for drinking water
i estimate about 24 lbs of head preassure to the top of the tank and about another 9 psi from the top to the bottom of the tank so the valve and pump need to be compatable
