How to Maintain and Prevent Problems
Once a month, boil a few gallons of water and carefully pour it down the sink. Boiled water is significantly hotter than tap water and it will help dissolve soapy, greasy materials that are coating the walls of your pipes.

Utility Room
Closing and reopening the water faucets that supply the washer each month is a good idea, especially if you have hard water. Otherwise they may bind up and not be able to be closed when needed, or leak at intermediate positions.

Hot Water Heater
All water heaters should be frequently checked for leaks. It's important to check the pipe connections, the valves and underneath the unit. Simple preventive maintenance will help you avoid lasting damage from a leaking water heater.
