When water freezes, it expands by approximately 9%. When this water is in your pool skimmer, that expansion is just enough to cause damage. Instead of repairing or replacing your pool skimmer each spring, protect it with a Skimmer Guard when you winterize your in ground or above ground pool in the fall. This handy (and affordable) little gadget is made to absorb the expansion that occurs during a freeze, so it protects your skimmer all winter from damage caused by expanding water. Instead of expanding outward and cracking the skimmer, freezing water will actually compress the Skimmer Guard.
Skimmer Guard proves to be an easy and inexpensive way of saving yourself the hassle and expense of dealing with a damaged skimmer each spring.
