Went to my daughter's flat this morning intending to flush out her
radiators. Stuck a hose on the drain cock and opened it a little, water
poured out around the screw. The cock is very close to the floor, so not
enough room for a container to catch the water, and in any case it was
coming out quite fast. Is this a normal scenario? I'm going to leave the job
for another day, but would welcome any advice as it will have to be done at
some time.
