After returning from our holiday my children informed
me that one of the loft overflow pipes had been dripping whilst we
were away. I decided to have a look around tonight when I put the
cases away i was suprised to find the water
in the expansion tank was hot! i have been told it might be a leaking
coil in the cylinder tank. i have bailed it out a few time and the
water looks a bit brown near the bottom of the tank .
im a bit short of money at the moment has anyone any ideas what it
could be .what would happen if i left it dripping
thanks jane

How old is the cylinder? I had exactly the same prob. with mine which
was 35 yrs. old. Cost around £250 to replace and fit.
Leaving it like this will increase your fuel bills and make a wet mess
under the overflow.

If it is leaking of water from the hot water system into the heating
circuit it is likely to accelerate corrosion, rusting and sludging of
the heating circuit.

It really does need to be fixed. The brown water in the bottom of the
tank is a tell-tale sign.
