Water down tundish

[Talkingbollox]

Hi, can I have some advice please?

Water is being expelled down the tundish B on my sealed system. The pressure vessel A was replaced about a year ago and is holding pressure, and sounds empty and hollow, so I don't think it's the PV. The water expelled is cold.

What could be wrong please? Is it the Inlet Control Set below the white PV? What about the Pressure & Temperature Relief Valve attached to the cylinder?

Thanks

If it's constant it will be your pressure reducing valve

It is not piped exactly correctly as the tun dish should be within 500 mm of the T&P valve.

Work on unventeds should only be done by someone who holds the appropriate certificate.

So the advice might be to call in someone qualified.

They should also be serviced every year.

Also a flexi looks like it has a kink and what is that big of rag doing ?

Thanks, all

I'm going to buy the part and get someone qualified to replace it. However, the part is clearly TS201 per the manual:

However, if I do a search online for the part I get something like this:
http://buyplumbingonline.co.uk/prod...ntrol-Set-Cold-Water-Control-Valve-TS201.html, which looks different in that it's not as long? Where can I get the correct part please?

Thanks in advance

Probably superceded by now. I'd leave that responsibility to the fitter to be honest to make sure the pressures are correct or ring a company like advance water who will give the correct replacement from a description of the old one.
