err um . . whats a 'primatic cylinder'?. The house has a conventional vented heating system with a copper cylinder on the first floor.
The water tastes 'metalic'. If the cold tap is run for 5 mins then the water tastes fine. :oops:
Recently changed kitchen mono mixer tap, now cold water tastes bad, even after 6 weeks regular use. Should I have fitted non return valves on hot or / and cold supply to the tap flexi-tails? :roll:
