Regarding power shower replacement
Power showers should have isolation valves already fitted just before connections to the power shower - Sometimes they are visible above the shower on the wall, in the loft directly above the power shower or behind the shower in a cupboard. The reason there should be isolation valves is to allow replacement of your old power shower without the need to drain down the tank . Draining down the system, fitting isolation valves and refilling will take 1.5 - 2 hours above our normal shower replacement time and opens up the possibility of creating air locks in the system when refilling.
We charge £99 for the extra time taken emptying the water tank, fitting full bore lever isolation valves, re filling the system... if it is discovered when we arrive that no isolation valves have previously been fitted.
If your original power shower was fitted by a professional then there will be isolation valves already in place.
Central heating valves ( Gate Valves ) are NOT isolation valves - they are there to regulate flow and 99% of time leak after opening or closing them ! We will not try to turn off water supplies using these gate valves as they are probably seized or they will leak after closing them.
