What a great post. My pump pressure dropped dramatically and my cleaner had no pressure. i was going to call the pool guy, but after reading this forum took out the basket and checked the pump impeller - full of pine needles and hair. Problem now solved!

Great Posts....My basket just ahead of the pump is worn and cracked. My back pressure had recently dropped from 16 psi to about 6 psi. The open crack in the basket had allowed debris to enter the impeller blocking some of the ports. It was easy to pull off and clean. Put it back on and it's back at 16 psi and works great! I'm heading to the store tomorrow to get a new basket.

Baskets with a simple split can be "woven" together with fishing line, which can add another few months to their life.

8 psi is about 2 pounds lower than most DE filter systems running without the DE media.
I would make sure there is no bypass of filter involved.
But was going to respond to problems with baskets initially.
Baskets that are full of leaves and debris cannot pass sufficient flow that the suction of pump demands.
So sooner or later, the bottom will start breaking of the basket. Same applies to a pump strainer.
It is the most easy maintenance around the pool that even the kids can do on regular basis.
The debris and leaves are exposed to a great force of rushing water, that strips and deposit decomposed particles into the filter, adding phosphates into the water as a potential food for algae.
Same occur in a Polaris bag left uncleaned for a week.
The fact, that the junk is in the bag does not mean that we cleaned the pool!!

You need to give a bit more info.
Is the booster pump still running after 2 minutes?
What is the back pressure on the filter?

I have a inground pool. I have air bubbles coming out the returns. someone told me it could be the O ring on the lid of my pump. Also when the filter goes off the DE comes out the main drain at the bottom of the pool. i also notice this season when i closed the pool the main drain at the bottom of the pool did not blow. Please Help. :(
