As of the last 2 weeks my mains water pressure is dipping quite low at times. Used to get 2.5 bar + but now it sinks as low as 1.4 during morning and evening "rush hours" and will just about hit 2 bar at night. I realise that their small print says they are only obliged to provide 1 bar at ground floor level, but seeing that my pressure has been much better pretty much all the time for the last 10 years, can Thames Water be 'pressured' into sorting out the pressure 'that I am accustomed to'? There is no leak under my garden path, and i am concerned that all the many recent conversions to flats in my area has effectively doubled the number of working bathrooms and kitchens in my street.
