Hi All
In a bit of a quandary. I am in a position to change the Mains water pipe that runs under the floors downstairs.
The Mains from the road is probably 1958 Galvanised but as it comes alongside the house there is a raiser that changes to a 20mm blue pipe MDPE. Without digging up a concrete path I can T off this 20mm and take this into the new boiler position (Vaillant 837) with more 20mm (which I have got already) or do you think it is worth going to 25mm? One small problem is that I have not found a 20*25*20 T for MDPE?
I have just checked the flow rate from the 20mm ~ this via a (double?) check valve and a standard garden tap with a garden hose adaptor on because the water was going every where but the bucket. The T off to the house will be before the check valve.
Flow is 10 Litres in 25secs more like 22 secs.
Just some further info from our bedroom windows we look UP to the Water Tower about 1000 yards away.
Thanks in advance
Mike
