Low pressure water supply in cold water tap in washbasin

Postby Dora Downes » Wed Jun 09, 2010 12:51 am

We used to have a separate toilet next to the bathroom. When we have the loft extension built the WC was relocated to the bathroom to make way for the new staircase. Since then we have very low pressure supply in the washbasin cold water tap. Every time we use and flush the toilet, there is hardly any water from the cold water tap to wash the hand. I suspect the plumber who relocated the WC might have connected the feed for the cold water tap to the lavatory cistern as well. Is it right to do this or should the plumber have provided a separate feed for the lavatory cistern from the tank in the loft? Can anybody advise what's the remedial work required now to sort this out. Please help!

IT was once regulation that toilets should flush in the event of mains failure and in certain situations, bath and basin colds should be tank fed too.

Although there are a few special exceptions, this is now accepted as bad practice and cold feeds to basins, toilets and baths should be mains fed.

Insist the tap is mains fed.
