In brief: Pentair replacement drain plug for Cristal-Flo II sand filter. Pentair part number 154712Z.
The plug that saves your filter from freezing
The filter drain plug is used to drain the water from the tank when closing the pool. A filter tank that retains water through a Quebec winter can crack under the pressure of the ice.
Like a pump plug, it is handled twice a year and wears out over time: worn threads, a hardened gasket, or simply getting lost.
A plug that no longer seals properly causes a continuous leak at the base of the filter during the season.

Frequently asked questions
Do I really need to drain the filter when closing the pool?
Yes. This is one of the most important steps in winterizing a pool in Quebec. A full tank that freezes will crack, and a cracked tank must be replaced.
How tight should I screw in the plug?
Hand-tight, without tools. The gasket provides the seal. Forcing it can crack the tank threads.
Does the sand need to be drained too?
No. The drain is used to remove the water. The sand stays in place and should be replaced every five to seven years.
