I have a problem with my shower - it started dropping in temperature to where even on the hottest setting it now runs lukewarm at best. Previously has been taken apart and adjusted the flow from the inside which seemed to solve the problem for a while, albeit I had to have our boiler on preheated water to ensure it was hot enough, instead of the 'eco' setting (combi boiler). It's now started happening again and taking it apart previously was a ballache, so was wondering if anyone knew the cause of this? Other relevant info is other hot taps upstairs and downstairs are all fine, the shower has a mixer tap and our boiler is kettling relatively often.
