I'm getting my ballast system drawn out and can't seem to find any check valves i would like to have them in a 1" or 3/4" size. I would love to have some with a spring loaded flap in it so I have some pressure when filling sacs. But I'll go for any type. Please help me out. <BR> <BR>Thanks

My local Home Depot has them in both sizes for irrigation systems, nice free flowing units.

Shawn... <BR>You should let us know more about the system you are you installing... <BR>I am pretty sure you are you using simer reversible... <BR>where are you thinking of putting in your check valves? are you emptying out the same hole you are filling? <BR>if you are you only need one ball valve on your thru hull fitting(the simers will only let water flow when they are turned on thus acting like a check valve)

haha yeah gordon I'm using the pumps you shipped me. THANKS A MILLION I want a check valve on the overflow line so no air comes back into the sac, and I want another before the through hull so I can redirect the empty overboard so I can see when they are empty. oh yeah they are going to go into a 05 wakesetter lsv.

kewl... <BR>ok, I did not put overfil lines cause I can see all my sacs, and I just pump back out the thruhull mushroom fitting

you should definitely use swing check valves for that. most of the spring loaded types won't open below 3-5 psi, which is too much.

you can use PVC pipe (cut to size and glued) as an adapter to fit into your check valves. its a fast and easy, inexpensive fix. works great for me
