Tap water pressure problem

[crt]

Right, I've done the searches and found all the useful info on this site and elsewhere about how to clear an airlock.

Now it seems to me, if I've got pressure at the shower and flow to the loo (I think), but no hot and cold to the taps in the bathroom and the kitchen, I must have an airlock (if it is an airlock) between (1) where the cold feed goes to the shower and loo and (2) the boiler and where the cold feed goes to the taps. This being so, if I force some mains pressure water back up the taps is it going to clear the airlock if the boiler is in between? Presumably I just try to clear along the cold tap route and then the boiler will regain pressure once the airlock is cleared in the cold feed?

do you have a hot water cylinder and tank in the loft

or a combi or megaflo

The boiler is a simple immersion heater - just supplying hot water, with heating from storage heaters.

if you have a washing m/c fed from the cold main link the valves

if not you need a mains pressure cold tap and a hose to the hot

carrier bag comes in handy if you put your hands thro the handles

Hi, we've got an odd problem with our pressurised system.

you do not have a pressurised system

Sorry, you're right that we don't have a pressurised system in the conventional sense, but I think the immersion heater is pressurised from the mains to give hot water pressure (there are no tanks in the roof).

Sort of. Much smaller, fewer bits on the outside.

then you do have an unvented system

you should not have any airlocks there must be a restriction somewhere

Answer? Fancy modern mixer taps with a filter mesh at the spout. Completely full of crap. Unscrew the end, clean the filter. Job done.
