it's a system on the top floor flat i can't find any outlet for draining and as the pipes are the lowest part of the system (under the floor) how do i drain the pipes...
Use a washing machine self-cutting valve to drain the system from the lowest accessible point... Once drained, replace the bit of pipe where you cut a hole in it with a compression T-piece and a capillary drain cock to save getting the problem again.
