after having a new worcester bosch combi fitted the bath water pressure is very low. the kitchen pressure and shower are fantastic, what can i do to solve the problem. the fitter claims " there's nowt we can do."

your shower and basin taps are usually fed by 15mm pipe, the bath will be 22mm. the larger pipe gives the impression of less flow. it's similar to if you put your finger over the end of a hose, the same amount of water comes out but it seems faster. check the amount of water coming out of both sets of taps using a weir gauge, if they're not the same then you have a restriction in the pipes, or a valve isn't fully opened. it won't be a problem with the boiler.

read the spec on you boiler they can heat so many litres a minute.A lower flow rate boiler will struggle on a bath
