hi all
has anyone heard of a harco pack, we had it fitted in the 70's and instead of a hot water cylinder in the bathroom we have a double tank in the loft suppling both hot and cold water.
recently the overflow has started dripping but it only seems to do it when the c/h and/or h/w is on
the pack stands about 7ft so is hard to reach
any ideas about what the drip could be is appreciated
