I've just moved into a new house, and I have a problem with the
shower. It's a mixer shower in a cubicle gravity fed from the hot
water cylinder on the same floor, and the cold tank in the loft just
above. It produces not so much a shower as a dribble.


Just a thought - it's not just an airlock in the feed pipework is it?
Reason I ask is 'cause that's exactly the problem I have with my new
shower/bath/toilet. Will try to fix by attaching cold bath tap to
hosepipe tonight.
