Had this for a few years tried the arrestors you pressurise with a bike pump, but they loose pressure over a few weeks, bought two Pegler sprung ones fitted one made no difference so took them back.
So any ideas or recommendations?
Had a similar problem in an old house of ours, tried arrestors etc, nothing worked. Fitted a pressure reducing valve just after the stop tap and adjusted the pressure to a level that it didn't hammer, worked a treat.
