Have a Telford Direct Combination tank.
Turn on the tap and some hot water comes for 10s or so, then trickles
to a stop. Wait a minute, repeat, same thing.
Any ideas what the problem could be?
Thanks in advance,
This sounds like a partial blockage in the pipe that feeds cold water
into the bottom of the hot cylinder. Having had a quick look at a
picture on the Telford website this may not easy to fix :(
I had a similar problem with a differnet style of combination tank - In
my case it was limescale build up that blocked the bottom entry and I
used a bucket load of Fernox poured slowly into the small header tank
that was part of the hot water side. It looks like your tank may not
have this - just the main cold tank on top?
Thanks Peter. Cold tank is indeed on top. Tried pipe unblocker down
the feed hole and can feel/hear lumps of limescale moving around at
the bottom. Managed to get a good flow for 10 minutes or so, then the
damn thing blocked again.
Have tried 2KG DS3 through a funnel, but not having much luck. Will
try another dose later. How effective is DS3? Any more aggressive
cleaners that are safe with this type of kit? If I cut the supply off
from any plastic pipes, is DS40 a good idea?
