    Pentair Quad DE filter crack

    I was doing a filter clean on my 2014 Pentair Quad DE and I reassembled the filter and started it started it up.

    Went it started, water was rushing from the bottom of the filter. I took apart the filter again and I found a huge crack at the base of the pressurized shell?

    What the heck? Has anyone seen such a thing?

    Welcome to TFP!!!

    Was it leaking before you took it apart?

    It can happen, I had a Hayward split on the side (replaced under warranty).

    Hope yours is still under warranty too.

    No it was not leaking, however we have had a ton of rain in Houston and it has been hard to see anything dry. Pentair will cover it under warranty!

    Grids were a mess and I am battling algae now.

    I am not too familiar with that type of filter, so I am not clear if it is possible that the act of taking it apart and putting it back together could have caused the crack.

    Great that they are replacing it

    That's got to be a manufacturing defect. There's nothing at the bottom that is removed or displaced with a disassembly.
