I'm near the end of a loft conversion. During this the tanks were disposed of and now the plumbing is direct, no tanks, no megaflow.
The mains pipe from the road is still lead but the flow is quite good... so far. But I fear the pressure in the loft will be poor as its quite a long way up. All the piping from the new boiler appears to be 15mm.
So I was wondering would it be best to bite the bullet and go for an upgrade of the mains supply pipe, I assume the current one is a lead equivalent of old 3/4 inch - and get it upgraded to a new size in the blue plastic ? If so what size would be best.
Alternatively I understand that AquaLisa do a pump for showers that works off the direct supply - have I got that right? A plumber told me about it while installing the new boiler.
