Whenever I turn off any tap (H or C) in my house, there is an almighty bang as the water shuts off unless I do it v-e-r-y slowly indeed. Is this known as 'water hammer', or is that just the 'juddering' sound some folk experience?
I've been googling about this here, but am nor sure how to cure this easily? I don't want to close the stop c*ck or any in-line valves to reduce the pressure, as it's really not that great anyway (and I have a combi feeding the shower - the whole place has mains pressure water, no H or C tanks).
Is an 'arrestor' what I need, or is that just for juddering pipes? If this would do the trick, does it matter whereabouts it is fitted in the system?
Thanks
