I have fitted a bathroom suite in our loft conversion, previously it only had an electric shower, WC & small basin.
I have fitted a bath, WC and new basin.
Because it's a bungalow and the cylinder is downstairs and cylinder feed tank is in loft I had great problems in getting the hot to flow to the new upstairs bathroom. So I have fitted a Warwick flange and a Grundfos electric demand pump. This works great on the bath tap ( which is piped in 22mm all the way ). But the basin wont flow Unless I momentarily turn the bath hot tap on, this obviously creates a big enough pressure drop to switch the pump on, where as the basin tap doesn't because it's ultimately piped in 22 to 15 to 10mm.
Any ideas to fix this ?
