Quieten noisy main in bedroom?

[bpowell555]

Got a 15mm main rising from the bedroom floor on the first floor straight up to the cold tank in the loft. Its frickin noisy whenever the tank is filling, especially with the shower in the morning. Its currently exposed, covered in grey pipe lagging, in a cupboard. 2 year old reckons its rubbish.

I don't really want to reduce the pressure as its only a small tank and if you run a bath - big taps and bath - the tank will generally empty as it refills the immersion heater below, which will only happen sooner if the pressure (flow?) is reduced at the stop cock.. air in pipes ... blah blah blah!

Is there anything I can do other than box that pipe in? Replace it with a length of plastic pipe or a wider bore? Would that help?

Cheers!

Replace the float valve in the cistern in the loft with a Fluidmaster.
Put some flexible pipe in the supply to the cistern, to stop the noise transmitting back down it. You could use a good quality flexible tap connector (they fit the valves) or (I would prefer) a loop of plastic pipe going into the valve. Makes a vast difference.

Sounds like a great "mod" ... I'll leave this for a while and probably come back when I know a few more details,

Cheers!

Also/or try fitting a pressure reducing valve to the cold main

But for the same pipe that would reduce the flow right? Don't want to do that... ?

No, a pressure reducing valve reduces the pressure!
Flow rate is virtually unaffected

'Wow' why didn't we get one of these before (customer comment)!

Woo Hoo!!! Done it And in LESS THAN 2 YEARS!!! The thing is incredible. I can't hear it filling a half empty tank above the noise of the computer fan. Just waiting to see the fill level is up ... yep all good and soooo easy to adjust.

Cheers chaps!

I tried it without the tap connector and was fine. Have a service valve to add so when I get round to that - 2010? - I might add the tap connector, since the existing elbow is a bit ropey.
