PRV and noise from taps

[Craig24]

Hi,

When we bought our house the tap in the bathroom made quite a loud noise when turned on, both hot and cold, kind of screeching / vibrating. We replaced the tap and still have the same problem. I installed a PRV (this one) after the stop tap and it did fix the issue with the taps but it reduced my shower flow to much unfortunately.

I can attach the gauge to the PRV to get the pressure if that’s helpful. I already have isolating valves for each tap supply under the sink. Turning this down helps, but I end up with just a trickle of water if I turn it down enough to eliminate the noise.

I don't have much space under the sink to fit the PRV there, also its all open so it would also be on view. Any other ideas on how I can resolve my issue? I'm not 100% sure why its happening, my taps in the kitchen are fine with no noise at all.

There are a few options available,onsite investigation will determine the best solution.

Some plumbing is already badly installed with incompatible imported plumbing products but there are options,should be an easy fix thou.

Thanks Old&Cold, I should be able to pick one of these up from Screwfix, I'll report back. The tap did come with an aerator for for high pressure but that didn't seem to do anything.

The tap seems to make the noise when you open it a little, if you open it all the way its normally ok but very powerful.

My original aerator is like this

Cache Honeycomb TT Flow Regulator / Aerator M16.5 x 1 M16 x 1 https://www.amazon.co.uk/dp/B004PQQ8JC/ref=cm_sw_r_cp_api_EyGGAbQ3WC4P1

I don’t seem to be able to find a flow restricting one in that size.

Trace the noise, you might find it down to poorly supported pipework or an ISO valve not opened fully.

A lot of that type of noise is down to pipework sizing that's not properly designed to ensure water velocity is kept below levels that can create noise or sympathetic vibration in pipework and valve gear.

You can install inline flow regulators that will reduce flow without effecting pressure.

Just an update. I spoke with Burlington and they suggest changing my cartridges for quarter turn instead of screw down. They sent me some out to try, I fitted them this weekend and its resolved my issue. No more noise!
