ESI ZV 222 Problem - Noisy!

[derbyphil]

There’s a horrible squealing noise sporadivally coming from our hot water tank cupboard and it seems to be due to the ESI ZV 222V which is also very hot (is that usual?)

I’ve looked into it and can see that this can be replaced for about £30.

Is this a known issue for those units and would a direct replacement for it work - and how easy it to replace it for a real novice? How much would someone charge to do it?

Thanks!

It depends on the noise, if it’s fitted incorrectly, then just replacing it wouldn’t work, although I’d expect it to make noise every time. Can you video/record noise and upload?

Hi, this just started up again this evening. Very loud!
Video uploaded and attached. Any advice/suggestions?
Thanks!

Heads gone

Thanks - is that just a case of replacing that part? Or rather getting someone to do it?
Expensive?

Just the head so if you can get the exact same model just a simple swap over

Thanks - when I search for the exact model number I get lots looking very similar but none identical! Will keep looking! (2 port head valve)?
