yes its very simple the Y valve (3 way port has gone!) which is in the airing couboard. it is a electronic valve which is normly just above the pump. They are about £40 to £ 60 and very easy to change you don't have to be corgi to touch it! Because its water. turn the cold mains off first. drain the water out of the rads with a hose pipe. when empty of water undo the three nuts on the valve and fit new valve body. turn the fused sper off!!!! and wire the 5 cables into the electric junction box one by one matching the colours. if you have a combi boiler it is the diaphram that has split, call a gasman it is a big job that you can't do!!!!
