Try somewhere like Plumbcenter. They list TRV4s at around £19, but
you should be able to negotiate them down a fair way - I think I paid
about £12 for mine a couple of years ago.

Alternatively......

Pegler Terrier from Plumbcenter for £15 list......

Honeywell from BES (www.bes.ltd.uk) for about £10

should all be OK.

To email, substitute .nospam with .gl

Thanks for the link to BES I hadn't found them. I did come across Drayton
RT212 for 8.45 incl VAT here though

They seem heavily discounted so I will probably order those.

I take it that Fernox MB1 will be sufficient as an additive.

So now I feel ready to tackle the job!
