Water hammer keeps cropping up in the mains feed coldwater system in my house.
It used to effect the downstairs toilet cistern, so I replaced the valve with fluidmaster type. that fixed it for a bit.
Then the upstairs toilet cistern whistled and whined when filling, fixed that with fluid master valve.
Also a big 'thump' when washing machine/ dish washer shuts off durring filling.
( adjusting stop cock helped that a bit )
Now another toilet cistern makes whining/ juddering noise when it fills, and the other one whistles when cold water is turned on anywhere else in the house!
Have I misinterpreted whats happening?
What next? Some type of damper on the cold water mains or new mains stop cock.
The mains pressure in this house is high and the stopcock is only open a quarter turn, it that the cause?
I know lots of questions, but what do you think I should try next?
