Hi
I've recently had a new bathroom installed. I've noticed when I flush the downstairs loo there was a hammer type noise under the bathroom floor when the cold feed for the loo turned off/ same with the washing machine.
So I turned off the mains water supply. Opened the highest tap first (bathroom sink) and then all the others down to the lowest , which I thought was the garage water tap (about 2.5 ft off the ground). This appeared to work! Great I thought, until I switched on the dishwasher and ran a bath upstairs. Whilst in the bath I noticed every time the cold feed for DW stopped it clunked/ hammered under bathroom floor, even rattled the new towel rail.
I tried the downstairs toilet again and sure enough the same hammer noise is back!
Any ideas? One thing i notice when running the bath is that the flow isn't brilliant and seems to be a bit spurty. And after I turned off the mixed taps it throws out water 3 times over several seconds. I bought these taps as seconds in a reputable bathroom place but wonder if they are faulty? Can they cause air locks?
Or was it that I needed to have the dishwasher on when I drained the system? The dish washer was all plumbed in etc but not turned on when I drained the system.
My house was built in 1978 and not sure if it has air chambers
Any ideas gratefully received.

P.s. I tried ringing the bathroom fitter but he is ignoring me. Its worrying as he's used all push fit stuff and I had the bath switched around, and toilet cold feed moved slightly and sink moved. So now all the pipes are loose under floorboards/ bath and not fixed. Can't easily get the boards up anymore as they've put hundreds of screws down in a plywood floor (ready for me to tile onto)
