Evening Chaps, I have recently installed a bath mixer tap, It is a 3 hole design, the spout occupying the centre hole and the taps the 2 outer holes. I guess the water mixes in the pipes before the spout as aposed to within the spout. My problem is that when the bath taps are off and either the the taps on the basin are used or if the toilet is flushed, the bath tap sometimes trickles a small amount of water. Clearly if someone is in the bath at the time and this happens, it can be quite unpleasant and sometimes painful if the hot tap was last used, I have 2 young children, which obviously heightens my concern. The cold supplies to the bath, basin and toilet are from the rising main and the hot from the gravity fed dhwc. Sorry for the long post but if anyone can point me in the right direction, I would greatly appreciate it. Thanks, Ian.
