One noisy upstairs radiator

[qzwxec10]

Hi all,

I registered on here with the hope you’ll be able to help me.

I have one radiator which when the CH is turned on it makes a loud rushing noise (the only way I can describe it) it’s loud enough to wake you up in the morning.

The only way to stop it is by turning the pump down but then the rads furthest away from the pump will only warm up slightly.

The rad in question does not have a TRV, it’s just the normal valve and is the first radiator in the cycle.

This is the only radiator with any issues and all of them have been bled.

Thanks all.

Try adjusting the lockshield valve on the noisy rad

Try adjusting the lockshield valve on the noisy rad

I adjusted it this morning while the CH was on to see if the noise changed, no luck.

Is the locksheild on the outlet side ? If not try adjus the other valve

Sorry for the late reply, lock shield is on the outlet side.
