You will start off by getting a five gallon bucket and small electric pump with two washing machine hoses. Mix 1-one pound box of TSP (Tri-Sodium Phosphate), 16 ounces (2 cups) of bleach and hot water in the five gallon bucket. Drain enough water from your system to allow this mixture to be pumped into the water lines, and circulate throughout the system for one hour. The best location for hose connections is the hot and cold washing machine valves. Drain the system completely and repeat this process again. After the second application, you will want to flush the system out through each fixture for at least 15 minutes.
