I had this same problem a few months ago, especially on the hot. How is your pressure ? Mine was very high, about 6.5 bar,. I installed a pressure reducing valve taking the pressure down to 3 bar and this sorted the problem.

Why not install a Pressure Reducing Valve on you incoming mains, they are generally preset at 3bar, altho can be lowered further. Available from A Plumbers Merchant, and very easy to install.
hi all, anyone tried breaking up a steel bath ? If so, whats the best way ?
Was thinking of taking an angle grinder to it.
Need to break it as the stairs are too steep even for a mountain goat !!
