I'm still planning to get a Megaflow system installed (eventually), but I read somewhere that you had to make sure that the incoming water main was of sufficient pressure and flow in order for it to work properly (i.e. provide adequate flow at the taps, etc.) The article suggested that 15mm mains supply was not sufficient unless it was a very short run from the road, and that 22mm should be used. The article gave the example of flushing the WC which reduced the water from the taps to a dribble.
Well, I've got a 15mm copper main supply and it's about 3m from the road (where it changes to water company plastic, I've no idea, because we don't have a stop cock in the road. We have a shared supply with our neighbour, with a joint stop cock about 200m away). There seems to be pretty good flow (even with the WC filling up), but how can I assess whether my mains supply is adequate for a Megaflow system to work at its best?
P.S. What's a tundish?
