Just installed new filter and pump. Upgraded my filter from 100sqft to 320sqft for 13000 gallon pool. Everything seem to work except the filter window in the pump shows air bubbles, which start as the size of a couple of quarters, then over night covers almost the whole lid. I am afraid there is air coming from somewhere. The installer checked the water pipes with pressure, and they are OK. He says nothing is wrong with the pump. My single speed old pump had no air in the filter. I am worried that the pump is no good, since we checked everything, and it is brand new (including a second lid o-ring we checked). Should I get the pump replaced, is this common for Pentair pumps?

Bruce,
the cartridge element system you have is designed to be used for at least two seasons before needing to replace the elements. You are correct thinking that the pressure going through the filter is causing the problems with the cleaner.
if you take the elements out of the filter and see if cleaner works that will show you whether or not it is time to change the filter elements. That filter is very expensive to replace. cheaper to just change the elements.

Here are a couple of thoughts. If you install an intelliflo pump and run it for the same amount of time and at the same rpm as your current pump, you will still have a savings. If you drop the rpms by 1k, you will have an exponential savings. Go to the pentair website and use the program to estimate your actual savings. You can still run the heater at a reduced flow setting but there is a limit, you have to check with the heater manufacturer to see what the minimum is.
If you are running a conventional pump 24/7 you are using a ton of energy. You should be able to run the pump for 8 hours a day and achieve the same results. For instance, running the pump from 4am to noon should give you a good window to maintain the heat and not run it all the time. It also depends on if you have a cover on your pool when it's not in use. If you don't, you will lose significant heat when it's not running, however, running it early morning should give it a chance to heat back up before you want to use it again. You will have to experiment with timer settings, etc..
I really do think the intelliflo pump is a great pump. The rare earth magnet design allows it to be way more efficient than the conventional pump. It is so much more efficient that when it's running, you can hold your hand on the motor and it is just warm. Your pump motor probably runs very hot, heat is a by product of inefficiency. I hope this helps.

More than likly it's a square flange motor. If the noise is just starting when you take the pump apart you can check the impeller for problems but the most likley is a bearing going bad from a seal leak. If you remove the wires and take the motor with the back half of the pump to a pool store they can diagnose it for you and do the nessary repairs at the shop. Usually they will do this for a small bench fee or for just the price of the nessary parts.

check the connector on the back of the motor as shown below:
