So, further to my quest to improve the bathroom, I'm now looking at pumps... Stuart Turner seems to be highly recomended, but we blew the budget on the bath... So we're looking at their "Showermate" range rather than their "Monsoon" range... and what I've just noticed is that basically the showermate range use 15mm fittings and the monsoon use 22mm, and we need a dual pump.
Our plumbing round the HW tank and from there to the bathroom (both hot and cold) is 22mm. So would fitting adapters to an ST Showermate pump have any adverse effeect? We're probably looking at the 1.4 or possibly the 1.8 bar pump. It's only to drive a single shower and fill the bath. (Which already fills reasonably quick anyway, probably due to all the 22mm piping)
Or should I really squeeze the budget and got for a 1 bar Monsoon? (the performance curves are almost better, despite the reduced pressure)
Current max. head of water from the top of the shower to the bottom of the cold tank in the loft is only about 1 metre and while the shower is adequate, it's nothing to write home about, so just about anything will feel better!
I looked at other pumps (on the Plumbworld site) and while some of them have 22mm fittings for less money, none of them seem to have the flow rate for the same pressure as the ST pumps do!
Cheers,
Gordon
