Hi All,
Following installation of a new hot water cylinder located on the first floor of my house (indirect system) I noticed a drop in hot water pressure. The installers couldn't find any fault but hinted at a possible partial blockage in the pipework predating their work! This situation has continued now for some months and I haven't been able to find a plumber interested in solving my problem (guess there's other more lucrative jobs to do).
As a reasonably skilled DIYer I thought the best way was to use the old washing machine trick and hook up the mains and hot supply (normally feeding the washing machine) and flush the cr*p out.
The risk is that I might blow the cylinder but if the cold feed to the cylinder is in the closed position, I reasoned that the water (now under mains pressure) will exit via the expansion pipe in the loft along with the offending cra*p!
It's not an airlock incidentally (sometimes you can hear a noise downstairs when the hot tap in the kitchen is turn on) sort of humming ossolating sound which will stop if you turn the tap off, then on again.
What do you think guys?
regards
Barry
