my kitchen sink isn't draining.
I thought at first that the water in the gulley had frozen, but after
several kettles of water to get through the accumulated ice and snow on top,
I've found that it's OK - the problem is in the pipes leading from the sink
to the gulley.
I hadn't noticed before but at one point, the pipe has sagged and this part
has clogged up with ice due to a dripping tap, of course the entire length
back from this, towards the sink - a run of 10 feet including 3 90deg bends
as subsequently completely blocked with ice, so a word of warning to
everyone, check these ASAP, especially if you have a washing machine
draining into a run.
