Water providers generally require assemblies to be tested once a year by a certified tester, with the results filed, and commercial properties and homes with irrigation or fire lines are the most common cases.

Heat, hard water and shifting clay soil do most of the damage here. Summer heat and hard water wear out water heaters and irrigation valves ahead of schedule. Half of the homes in Oak Glen were built before about 1992. That era means mostly copper supply lines and plastic drains. Some homes from the late 1970s to mid 1990s used polybutylene pipe, which has a history of failing and is worth checking for. At around 3,137 feet, winter nights can drop below freezing, so insulate exposed pipes and know where your shutoff is.
