Tricks for putting the lid on the pump basket back on?

[pmcd]

I have a Pentair Dynamo pump. I removed the glass lid to clean out the strainer. Now I can' get it back on. It has to be rotated so that it fits into two groves. The problem is that the lid isn't flat enough for both sides to fit into the groves. I thought turning on the pump would suck the lid flat on so I could turn it but that didn't work. Can I hammer it in?
Very frustrating. It looks like it should be easy but it Isn't!

Any hints would be much appreciated.

Are you sure the o-ring is completely in place?

Try a little pool lube (plumbers lube, silicon based) on the o-ring. That could be holding the lid off just enough to cause what you describe.

If it is warped, you may need to buy a new lid.

This may or may not help...i have the intex sandfilter...and when i tried to put the lid back on when I cleaned the basket i had one hard time....i had forgotten to close the return valve! I only closed the outlet valve...so water was coming backwards through the pump and making it hard for me to screw on properly

Thanks for all the help. Putting some vegetable oil on the o-ring seemed to help. It finally went back on. Am getting a new pump this year so I hope I can get a different design.

Why would you use vegetable oil and not a gasket or pool lube? You always need to lube the o-ring to ensure a good seal.

It's better than petroleum oil!

Valid point

Wonder if peanut oil works to?

I read about that in some thread here. Couldn't hurt and I didn't have any pool lube. This had just never happened before. I guess I should go out and get the proper stuff.

In any case, it did seem to work though it might have just been a fluke. The whole waterworks' structure is a real mystery to me. The terminology, types of pipes, flow rates, leaks, etc... you name it. Just seems very complicated.
