we had an electric Mira shower for approxamately 8 years, which worked well until the temperature began fluctuating from stone cold to intensly hot, regardless of med or high setting or temperature setting.
A friend donated a new electric Mira Sport which was duly fitted only to find, although not as severe, the same problem exsisted. This has been sufferable until now.
Now when the button is is pushed, irrespective of any settings, it cuts out after approx 3 seconds. If the button is jammed in at least it works, but still temperature fluctuating.
The mains water pressure to the bath tap is strong, so I assume it wont drop on the rise to the unit to significantly effect the shower. (will it?)
Just a bit of guidence as to whether it is in fact the shower itself, dont want to purchase a new shower if it could be other reasons for the problem.
Any advice would be greatly appreciated.
