Ultimate Compensator, 1 1/2″ MPT, Winterizing Accessory CST003
Give the ice somewhere else to go.
Ultimate Compensator, 1 1/2″ MPT, part CST003 is a pool closing accessory stocked under SKU PST-CST003. Compensators sit in the skimmer and take up the pressure of expanding ice so the skimmer wall does not, and blowout plugs let you clear a line with air and then hold it sealed, and both come down to the same thing: no trapped water where a freeze can split a fitting. Match the size in the part name to your skimmer or plumbing before ordering, then set it as the last step of the closing.
