Waterhammer
Waterhammer
(OP)
We live in a 2 storey home with washrooms upstairs and downstairs. In the last week, we have a waterhammer noise that continues until a tap in the washroom to allow water to run.
Can anyone suggest the cause of the waterhammer 'buzz' and a means of stopping it, or even where to try? It is just recent event, but, is annoying.

"Waterhammer" is not a continuous thing, and in a typical house, it's more of an echo of the valve being closed, given the speed of sound in water.
What's initiating the noise? Have you tried changing the speed of closure of the valve?

RE: Waterhammer
I ask because in my current house, my AHU drain to the master bath drain line. About two years ago I noticed noises and it would stop when I turned on that sink (the water muffled the sounds coming from the open AHU drain). I installed a vent on the AHU drain line to minimize the pressurization of the line and I cleaned the line. The sounds went away for over a year. When the flex hose section starts to clog (located in the vanity in the master bath) it will start to pop occasionally, so I just pull out the hose and clean it.

Is that the valve that 'fills' the toilet tank?

It's just started in the last few days.

I haven't been able to locate an expansion tank.

You toilet valve may be chattering, dropping the pressure by opening the downstairs sink lets it shut fully. The toilet valve may need to be replaced but the root problem may still be excessive water pressure.

RE: Waterhammer
As a point of fact, a toilet flush typically cannot create a water hammer; the shutoff of flow into the tank is gradually reduced by the float valve, depending on type of float valve. The older ones with the floating ball and arm had a slightly quicker shutoff than the column float types.

Just change the washer or diaphragm seal on the toilet in question and it will go away.
Been there, done that. It works.

If you watch the level in the tank, sometimes you can see it setting up a wave in the tank, sometimes it just makes a strange noise as it gets close to closing.
Let us know.
