Pump Issues

[superduperwesman]

The air has got to be coming in somewhere?

do you have any elbows close to the intake?

I glued all the PVC together and fit the softpipe section onto the barbs with a heat gun and ty-wraps. Any easy ways to check for air leaks? I left the pump off for a few hours and there was no moisture on any of the connections.

I do have a 90 right off the end of the pump for the intake but how would this allow air into the lines?

I am starting to think its the pump... it is pretty old by the looks of it and they sell new O rings online so I am thinking that O ring is a seal that keeps the air out which is failing. It would be a bummer if it was the pump cause its the second one I have bought for this tank. The first was a Q1 3000 which was way underpowered. Might get a Q1 6000 if I cant find a fix in the next week or so, JL has it onsale.

Not likely but it could just be the plumbing, the pressure drop on the pump input might be too low which could in theory liberate dissolved gasses. To test for this try restricting the output and see if the bubbles stop.

The ty-wraps look a little ghetto but I tried to tighten up the connetions in desparation...
