(A) With the approval of the Indiana State Board of Health, the water utility is now installing check valves on all water services.
(1) This is to prevent backflows due to high water temperatures that some new appliances require.
(2) The water pressure caused by high temperature when the water is heated results in the pressure release valve operating.
(3) If the pressure relief valve does not operate properly, the water pressure could raise to a level that might cause damage to some appliances.
(B) To alleviate this problem, the water utility recommends that all water heaters have an expansion tank installed on them.
(C) The water utility also recommends the use of a pressure reducing valve where the water pressure exceeds 80 p.s.i. Pressure reducing valves can be supplied at the owner’s request per the appropriate sections of this code of ordinances.
