Noisy TRV.
I recently replaced one of my radiators and took the opportunity to
fit a TRV. (There are none fitted to any of the other radiators). Now the radiator (or just the valve?) makes a loud noise when the system is running - not quite a hissing noise - more like a "rushing of water" type noise. If I turn the TRV up or down a notch, the noise stops for 5 minutes. then starts again. Any idea what could be wrong? Thanks, Mark. |

Is the TRV bi-directional? If it is, you may well have installed it set for the 'wrong' direction. If it's like ours, you simply remove the sensor head, rotate a collar and then reinstall the head. No need to get wet! -- F (Beware of spam trap - remove the negative) I'm not sure - how do I tell if it's bi-directional? It doesn't stop the radiator from getting hot at all - everything seems to work just fine. Thanks, Mark. |

If you've not got the box then perhaps someone will be ale to tell you if you post details of the make and model on here or do a search on the manufacturer's website. Alternatively does it have an arrow marked on the body in the direction of flow? Andrew |

It should have an arrow on the body indicating the recommended direction of
flow. Modern good quality TRVs such as Danfoss, Pegler, Honeywell etc are bi-directional and quiet. If yours is a cheaper make then it may not be bi-directional or quiet. Davy wrote in message ...
