[G.A.S.]

5 bad brand new pumps right out of the box in one summer. (4 months).
Went to a different supplyer and not a problem sence.
Make sure you do the tests and inspections of lines per wildman.
and just for chitz and giggles I wounder about the new filter. I dont know if you can install it backwards or not. some filters have a anti flow back valve and should be installed per the arrow, only flows one way.
Just a thought
