Have read all the other posts on this problem and before i try some mods would like to see what others think,the washing machine solenoid is the start of the noise and so far have fitted a Mini Rester to the m/c and it has lessened the noise but that is with the water pressure at 1 1/2-2bar with a prv and the main problem arises when someone is using the elecric shower and the mains water is drawn off the temp rockets before the stat can adjust.
The cold feed to m/c comes down the kitchen wall and has a 90% bend then along to a washing m/c fitting with shutoff.it then carries on to the sink via a half turn full bore shutoff valve and then outside tap but that is not fitted at the moment,all pipework is well clipped and i have fitted a new stopcock on the rising main but having done lots of reading on this i am coming to the conclusion that the full bore shutoff is not what it states and coupled with the other bends in pipework close to m/c is acclerating the water when the solenoid shuts off and causing the noise,just wondered if i am thinking to hard or on the right track before i tackle this problem again
