Chuck,

That is GREAT news about your pump! It is a beautiful pump and VERY quiet!
I guess I may have gotten a dud.(not the 1st time)
I thought about doing the same thing to my check valves but didn't want to screw them up.They are pretty expensive and they were on the small side for me anyway.
I have since replumbed my tanks to a common switching valve with no need for a check valve.It is the most simple setup I could come up with and it works great.


I'm glad I could help.

P.s. If anyone needs a set of the check valves,let me know! I will make you a great deal!!!
