I've been doing the service work at a nearby three story office building.
The building was built about 8 years ago and when the restrooms were plumbed, water hammer arrestors were installed in all the required locations.
Since then, every time a toilet or urinal flush valve is activated, the pipes hammer. The arrestors are sized correctly and were changed shortly after the building was done.
I recently went to a seminar for Zurn and learned that if you install a triple filtering diaphragm kit, either in a Sloan or a Zurn flush valve, the hammering will go away.
Needing 30 flush kits and not so sure this idea would work, I talked the Rep into giving the kits to me If it didn't eliminate the hammering.
Eight years of hammering is gone!
