I have just fitted a new Wickes 'Vision Tall' Kitchen monobloc mixer tap.
http://www.wickes.co.uk/Vision-Tall-Sink-Mixer/invt/417166
The hot flow from it is great, but the cold is very weak. The tap is only 2 feet down the pipe from the cold stop tap, and the water flow/pressure in the house is fantastic - almost too high!
The isolation/service valve is fully open, so thats not the fault. There is a non return valve on the end of the flexi, where it attaches to the pipe/service valve.
Is it the return valve that is killing the cold flow? How can I test the non return valve?
