am trying to take out old washing machine, but am unable to turn of stop valves on water pipes as they appear to be in a fixed position with a mall screw in top- how do i turn them of? do i have to turn water of at stop cock and will this affect my combi boiler?
This might be better suited in the plumbing forum.
Sometimes I feel like if I answer any more questions it is like someone trying to climb over a fence to jump off a bridge and me giving them a boost.
