Are they the same? I can switch the heads between our two valves easily if one fails.

Can I ask, our combi boiler which is a Worcester something is about 12 years old now and sometimes when you switch the hot tap on it gives an almighty clattering for a few seconds, like something is struggling to open maybe. It is not something that happens every time, it wouldn't happen for instance when we had the boiler serviced and the engineer was on site and he serviced it and found apparently no problems but of late it seems to be getting worse and even now getting a buzzing vibration when the heating kicks in. Is that a common problem or do I need a guy on site when the noise happens?

I’m going to bell the local plumbers merchant and see if they have them.

I just replaced the motor, rather than the entire valve assembly.

Buzzing when the heating is on can sometimes be something as simple as the case vibrating slightly, you can tell if it’s this by pressing slightly on the case whilst it’s running. As for the noise on the water, it could be the divertor valve sticking, but as there’s so many things it could be you need to hear the noise to correctly identify the source.
