Mira Combiforce 415

Your shower will probably have come with the 150.58 which is1.25mts long you may prefer the 150.60 which is a little longer.

Regarding the temperature fluctuation or cool running it could be a faulty cartridge however to check this, see if you can get hold of the hot supply pipe before it enters the shower or perhaps as it leaves the boiler.

If when holding this pipe the temperature fluctuates or goes cool then the problem is not with the shower but more likely with the boiler as the shower can only deliver what the boiler sends to it.        #

Disregard the temperature at the taps as they have a different flow rate.
