Just wanted to update this. Ray PM'd last night to ask how I wanted to get the new pump swapped over. I said I would go into my local branch, I did so today and it was swapped over with no hassle at all. I think the new one is even a TT60, that's what it says on the box but I haven't had a chance to open it yet.
Brilliant service.
I got a boiler from Williams a couple of weeks ago delivered on time very well packaged spot on price and service well done ray I will be back for more .
