<p>Good deal Don,</p>

<p>Did you glue them or use sealant? I use plumbers tape on most fittings now but Im glad you got it resolved. </p>

<p>I found this, hope it helps. Based on the below numbers in green, a 2" pipe should be more then enough.</p>

<p>I added a 2" vend pipe, found some of my bell caps were leaking air and I think that fixed the problem.</p>

<p>TCLynx, Yea i know but it was a thought. Thats why i suggested a larger drain line. By the way, I've herded cats before, get rid of the horse and rope cause they come running for cat food. If you can't push it, then pull it. Same thought with herding cats. It can be done.</p>
