The most common cause in the city of Lynnwood for dirty water concerns is rusty pipes. Pressure fluctuations inside the water pipes, especially if the service has been off for a time, turned on and off, tend to loosen the rust that has been clinging to the inner walls of the pipes. The rust comes in contact with flowing water and an off color will appear brown.
To eliminate anything in the water we must first find the source. If only the hot water side is colored, the suspect maybe a bad water anode rod that needs replaced. Talking with your plumber is recommend for this work. Also flushing the hot water tank is sometime recommended to improve the vessels life, again talk first with your plumber.
Galvanized pipes are also a cause of dirty water and normal use usually will aid in keeping your water clear and fresh. However, flushing your homes water system and normal use seems to be the best method in clearing up dirty water concerns for almost all our customers.
Please feel free to contact your water department for more ideas.
