Noisy header tank

[Thomas]

Hello

I recently had to replace the 25 year old ball valve in my header tank due to it not shutting off fully. The new valve shuts off ok but generates a very high pitched whistling when the tank is filling which is quite irritating at night when someone has had a shower.

One difference I've noticed is that water exited the old valve from its underside, whilst water exits upwards from the new valve and is diverted back down via a short plastic tube. Apparently this is required by new regulations? I've tried playing with the water pressure and I've also tried fitting a rubber tube to the valve but neither of these measures has much effect.

Can someone recommend a silent ball-valve or is this a problem they all have?

Thanks Thomas

Try a farm supplier - I bet their ball valves for troughs don't have this feature.

You could try a torbeck type of valve, these are very quiet in operation

1. change the rubber washer
2. clamp is firmly to something solid
3. wrap pipe in absorbent material
4. Fit a valve somewhre around halfway along the supply pipework, and turn it down till the noise stops.

Usually 1 does the job, if not progress down the list.
