Hardness 3 Ph 7.8 Chlorine .9 ppm Pressure 60psi Arrived to the home, customer states that whenever they flush the toilet they are experiencing water hammer. There are many reasons for water hammer can happen, mainly with high pressure in the home. I tested the water quality and water pressure during my through evaluation and discovered that the water quality and pressure fine. The sound does not seem to really appear as water hammer. It’s more of a ticking noise coming from the meter itself. Client stated this only started to happen 6 months ago and the existing meter is the older style. I advised to the client to have the water company swap out the meter to see if that resolves the issue. If the water company does swap out the meter and the home’s water pressure were to increase, I will need to install a pressure reducing valve “PRV” at the main with an expansion tank. If clients calls back to have us put a PRV in, I will credit today’s diagnostic fee towards that service.
