I have recently had a new bathroom suite fitted but now have low hot water pressure in my hot taps in the kitchen and my bathroom sink. The bath is still okay.the plumber who fitted it says it's the position of the water tank and that there is no air lock.he says there is nothing we can do. Surely there is? Can anyone help me please.

There are two questions that come to mind when I here about low pressure, the first is what size pipes were used for the hot side of your lines? The second is did the plumber check the fittings on the faucets? A lot of times what I see is that excess glue or gunk build up on theses valves and does not allow full flow, shut off your water supply under the sinks and take the hot water valve apart and check for gunk,glue or broken washers, open your water supply a little to allow water to clear out the line, put it back together and check. If you have any trouble or question let me know.
