Main Drain - Can"t run pump off MD

[ellry99]

Thanks for your response.

The wierd thing is - even if I have all the gate valves off - when I open the ball valve that leads to the gate valves I instantly lose prime. If I open ball valve slowly - there is tons of air in pump and then the prime eventually goes.

ellry99,

I don't think I would be helping you to just throw more possibilites your way. There are a number of pool equipment experts on this forum that will be able to guide your diagnosis based on their experience....

If you can figure out how to send a PM to waste, mas985, poconos or pool clown -- I'm sure there are others, too -- you'll be in more competent hands and may get this thing figured out sooner rather than later.

good luck!

Problem was resolved by my pool guy. He said my MD, Spa Skimmer, and Pool skimmer valves were bad. Replaced valves and all is running well.

Thanks,

All at the pad, huh? Sure beats having to dig up concrete!

Thanks for reporting back -- I'm glad it worked out for you.
