Water Quality - Dead End Mains

We are working with a client that is getting periodic water quality complaints. It is a complicated problem related to dead end mains and very low water use but one area of concern at one home is the fire suppression system that was install when the home was build. The water service to the home is 1 ½ inch. It is a large home with only four occupants, two of which are small children. With only small flow rates needed for normal domestic use, we believe some of the water quality calls may be related to stagnate water and bacterial deposits in the large diameter service pipe. In light of recent events regarding the State Fire Marshal calling for all private homes to have fire suppression systems, we have a question for our membership.

For those members that have fire suppression systems (wet sprinkler systems) install in homes, have there been any water quality issues within the home that could be linked to the large diameter water service which is required to feed the suppression system?

My company manufacturers AUTOMATIC flushing devices for dead end mains. Using only a 9 volt battery, these devices will spill a little water every night to keep up residuals and pass byproducts. Freezeproof and lockable. My name is Dan and cell is 314 374 6470.... see website at
