How to check the pressure of water is good enough for a mixer shower connector or Power shower

All showers require a minimum flow rate of 9L/min, all combi boilers are designed to achieve at least that. But consider if you boiler breaks down = no heat and no hot water. Get a litre measuring jug turn the hot water tap on, start a stop watch at the same time, when it reaches 1 litre stop the watch (be quick) divide the amount of seconds it takes into 1 minute this will give your boiler hot water flow rate E.G. 6 seconds ÷ 60 seconds = 10 ltr/min flow rate. If you choose a regular boiler this will involve having a hot water cylinder fitted too, which means that you have an auxiliary form of hot water by means of an immersion heater if the boiler breaks down, worth considering if only for the sake of having a back up supply of hot water!

You must use a 2/5mil bar thermostatic bar shower mixer made for combi boilers. The boiler will pump the water round at a standard pressure of 2/5mbar.
