Vent & Drain lines......

[rushin]

xpjim1,
Looking at your diy ballast install thread, did you use the same thru-hull for the drain & vent with a Tee & a check valve in the vent line?

[xpjim1]

Yes I did.

I got some 3/4" spring check valves this weekend at Lowe's.

When the bag is filling and venting, is there enough pressure to compress the spring?

[xpjim1]

Not sure. i used the swing check valves

[rushin]

Aaahhhh crap!!

Where did you get those?

[spooner]

on my system the pumps would not open the spring type check valves. I upgraded to swing valves this winter. BTW I am using simmers which I suspect pump more psi than centrifugal style pumps

[rushin]

ok, again where can I get swing type check valves?

Sorry, but I dont see the swing-door check valves listed on there now

What about this check valve, it needs very low pressure to open. Check Valve.

I got mine at mcmaster carr. 1 Inch swing check valves

I ordered mine from mcmaster carr today. I liked the idea of a 0.1 psi cracking pressure.

What about this check valve, it needs very low pressure to open. Check Valve.

Unless you use the water puppy pump it will push a spring valve open.
