    Deformed Piping Near Heater Outlet - Melted?

    I've read that schedule 40 PVC can melt close to the heater outlet, but never it expected to see it as my Aqualink has a "heater cooldown" enabled. Today, while backwashing, I noticed a deformity my pipes (attempted to capture it in the picture below). I assume it has gotten too hot. I have confirmed that Aqualink still kicks in the cooldown period after the heater has been on and increases the variable speed when the heater is on.My questions:

    * How urgent is it that I get the deformed pipe replaced?
    * Is there anything else it can be other than the heater melting the pipe?
    * What can I do to prevent recurrence?



    Thanks,
    Rob

    That almost looks like flex PVC on the vertical section. Are you sure it's melted and not just collapsed a little from being too long?

    I'm not sure it's melted, just my best guess. But it doesn't feel flexible at all.

    Defective pipe? A thinner wall section bulging?

    Again not sure. It's hard like any other pipe section. It doesn't deform if it give it a good squeeze.
