Hi
I recently purchased a refurbished top (2nd) floor flat and have a little issue with the shower, which I would appreciate your opinions on (I would note I have no plumbing knowledge!):
I should set out the following I suspect:
The water main is 22mm in diameter (new stopcock- fitted by our family plumber recently, fully on and back half a turn), this connects to a (sept 2004) Worcester Junior 24i combi, serviced by them last week. This was said to be fine when serviced. Hot water taps and rads all function fine. The problem pre/post-dates the service.
There is what I believe to be a 'thermostatic' shower in the cubicle. It's a chrome bar with a flow knob at one end, temp the other. No brand name apparent. Again late 2004 install.
I have used it everyday for the month we've been in, set at c.
34degrees and flow i guess on just enough to be a sensible power (which is very nice indeed). No problem.However, when my girlfriend uses it, which of course takes longer, at the same temp and flow rate, the shower goes cold/cool for
10-20seconds, after a while, then warms up again. I would note NO other taps/rads are on at this time of the morning in 'our' flat. This happens every day to her, never me.I have read various posts/talked to people and various things have been suggested, including
- reducing the mains flow (bolier manual) which will increase water temp?
- remove a 'flow restrictor' from the boiler, (worcester engineer) as he thought the hot water tap in the kitchen seemed a little cool/slow (i have not noticed this, but he knows what he's doing!).
- replace wax thingy in shower unit??
Thanks for your time.
