Hi All,
Would appreciate some advice. I have just had my cold water storage tank in the loft replaced and after 2 to 3 days I lose all pressure in the cold water supply to the mixer tap in the wash-hand basin. The plumber who did the job said it was an airlock and back-flushed the open cold connection using the supply from our power shower. After a day the flow began to diminish again and on day 3 it became a trickle only. Plumber returned and back-flushed again and the flow was reinstated but the same has happened again after 2 to 3 days but this time the is no cold water at all. He has recommended that we have additional work done by tapping into the cold water feed to supply the washbasin and toilet. All other cold water taps in the house are working OK and the problem is limited to the cold water supply to this one mixer tap. This is the first time I have had this problem and the back-flushing seems to only be a temporary solution as the pressure drops of over the next couple of days. The plumber says it is not related to anything he has done? Any suggestions as to what may be causing the problem and is his recommendation of connecting direct to the cold water feed the right thing to do? Appreciate any feedback.
