Grateful if somebody could help.
I have a gravity fed DHW system (cold water tank/indirect vented cylinder) with a Worcester system boiler. No FE tank.
My trouble is with the hot water from all taps/showers-its at a trickle (about 1litre/min!!), the cold water outlets are all fed from the mains and are fine. The cylinder is about 10-13 years old. The pipework from the cylinder to the 1st upstairs outlet is about 12m long in 28mm, mostly running horizontally. The dramatic decrease in flow has happened quite suddenly over the past few weeks. The water although at a trickle does heat properly (some consolation!!). The problem goes away for about a week if we drain the whole system but comes back after about a week.
any suggestions?!
