Hello,

I have some water hammer caused by the washing machine and dishwasher.
Should I get some of those arrestors and fit one by each appliance?

I measured the water pressure and it is 4 bar. I'm sure I read here
that it is useful to have a pressure reducing valve set to reduce
incoming pressure to 3 bar. Is that right? Would that be a better
idea?

Thanks,
Stephen.


Before reducing you pressure have a dig around you CW system for any €œdead
legs€� that might have become air filled. These can be a potent cause of
mains water hammers.
