Water Hammer

Water Hammer

Water Hammer

(OP)
We have  an apartment building client that is  experiencing water hammer severly. The  building is  more than 30 yearsold and allegedly the condition did not start  to occur until 1.5 to 2 years ago  and has  gotten worse. I believe that there is  either a leak in the piping that is going undetected or that air is somehow entering the system thru the recirculation pump.

Does any one else  have  any  ideas or experiences similar.

The system serves for units on two levels and has a condensing type gas water heater that appears in good condition.

The condition usually  manifests it self first in the morning and after periods of very low or no water use.

RE: Water Hammer

Does the service main have a PRV? I'm assuming the building is tied into the public water main. Was there any recent changes to the public service, increase flow or pressure? Were new fixtures (ie flush valves) added that required more pressure?
