ive just brought a 2 way thermostatic shower unit off ebay, and was wondering if i should buy a pump to give it some more umff?? i have a worcester bosch combi boiler which is running at about 1 1/2 bar pressure. the shower says it runs at 1 min and 5 max. its has a huge head on the shower but im unsure as to weather u can use a pump with any shower or is it specific units only??? also how do the pumps work are they connected to mains and do u need to switch them on before the shower, hope someone can help........thanks eddy
