Hot Tap on Bath Keeps Going Off After Installing new Taps Drainage and wastage systems and plumbing help, advice and answers

[blossom]

Hi! We had some new bath taps fitted recently. The cold one is fine, but the hot one keeps cutting out. When I'm running a bath the water stops completely. There's not even a trickle or a drip. If I turn the tap off and then on again the water comes back as normal.

Any help would be appreciated.
