We previously had a lever mixer valve for our power shower (i.e. left to right for temp, up or down for flow).
We then had a new boiler put in during the summer (this may or may not be relevant!) and a new hot water cylinder.
The pump subsequently broke, but that could have been age anyway.
We replaced it with one from Wickes for about £100.
We then started getting what I would descibe as water pressure surges and temperature changes (i.e. going cold)
So I thought the ceramic valves had gone on the old mixer and therefore bought one of the bar thermostatic mixers.
We don't get temperature surges now, but - depending on time of day (and I've found no consistency in it - does it when water is heating up or not, and when central heating is warming up or not), the pressure just dwindles away.
So, we got a Surrey Flange put in.
We still have the problem. It can be partly rectified by turning down the water pressure until it almost dies off, then turning it back on - result is a full flow.
I wonder whether we changed the mixer for nothing, but what is causing the problem now? How can we get a decent flow, all the time, from the moment it's turned on without having to turn it down and then up again?
Thanks in advance!!!
