Pool Filter Broken?

99% of the time when I see this it’s because the person who installed it had no idea what they were doing. Its because they plumbed your filter backwards, that’s right backwards, so call them up and have them come back and switch the unions around doesn’t take long and replace the parts. This part is less than a year old and look at the damage.

The filters are done for, they got a way to dirty to be cleaned. So this client will need all new filters, and the plumbing flipped around.
