Hi folks,
First time poster here. I’m looking for some help in addressing a water hammering issue. This is not a new issue - we bought the house a while ago and have always experienced some kind of hammering going on.
System setup:
* In-ground pump that fills a holding tank
* Pressure pump with two inline pressure tanks
* Taps off to the three supply pipes (feeding two houses and apartment)
When the pressure pump runs, we hear pipes banging pipes in the basement ceiling of one of the houses. Looking at the supply pressure entering the house I see it fluctuate widely while the hammering is going on. I recently repressurized the tanks to 48psi with pressure cut off set to ~50 - 52 psi.
I did some research and learned about check valves. Looking at my setup, I wasn’t able to find any check valves on the system. In particular after the pressure switch (base of tanks) and before the well meters. Also nothing inside the house either. Could this be the cause of the problem? If so where should I install the valve(s) and how many?
I’ve posted more details hires pictures of the setup at https://photos.app.goo.gl/XLVa5DsnQXfJx2uK6
Thanks for any help or suggestions,
Nigel.
