Air in Pump Skimmer Help

[les_garten]

I just redid the plumbing and Filter on my system to plumb in a new Filter. I also changed out the Volute on the pump(Intelliflo VF) Put a lot of Unions in. Removed the non functional Heater.

Now I have a problem keeping prime. Loses it pretty fast. Have air in the skimmer of the pump.

I replaced the lid O-ring on the skimmer. When I had the volute off, I replaced the large Volute gasket/o-ring, that seals the pump plate.

Today I put plastic film and tape around the intake pluming to the pump to see if the leak goes away or slows down. Didn't seem to change it.

I also replaced all the seals in the three Pentair valves on the plumbing from the pool to the pump.

Quite a bit of air and you can hear it running through the pipes to the filter, sound like sand flowing through the pipe.

I made a few videos if that helps. I also know that I used some PVC 90's and 45's that are not rated for pressure, so I'm aware of that, no need to point it out.

Did it have a suction side leak/air in the pump before you did the new plumbing?

No it didn't. But I also had a backcheck valve before. When I removed the heater I removed it as well. I just bought another one, maybe that will change something.

it will not, there is a leak somewhere that you changed.. you can do one of a couple things...

1. this may or may not work.. This stuff is amazing, I filled a hole in a 90 degree on the pressure side 9 years ago, it still does not leak..

2.. change everything again making sure you glue and keep the connection held all the way in for 15 seconds allowing it to seal completely allowing no air in..

I use rain and shine blue glue, it is strong and fast stuff, if over 80 to 90 degrees out you have about 3 seconds to get the pipe set before it is there forever..
