filters leaking between dome and tank body

[tigerucla]

A few weeks ago, our filters started leaking water when the pump would prime. Now they leak whenever the pump is at high speed as well. I'm thinking they need new o-rings. Could it be something else?

Is there some way to clean and relube the o-rings to get them to seal better?

Where's the best place to buy new o-rings? If I buy new o-rings, is it better to stick with OEM? Or are there any recommended after market parts?

Thanks!

Inspect the o-rings for tears, stretching, or other signs of deterioration. If they look ok rinse them well with fresh water, rinse any dirt or debris out of the track they rest in, and use some silicone pool lube to help them seal well. Make sure the lid is tightened down well and the o-rings are not getting pinched in the lid.

If the o-rings are damaged, your local pool store should be able to order them if they do not keep them in stock.

It could be as simple as turning the o-rings over ... I have to do this every time I clean ...
