any plumbers around Blackburn / boiler problems.

[a boardman]

my boiler has stopped working, the low pressure light is lit but there is 1.5 bar on the gauge, the boiler is an ariston eurocombi a23.

i did have a problem with the radiators downstairs staying cool whilst upstairs where warm (boiler upstairs) yesterday no heat at all in radiators downstairs.

the low pressure light comes on when it trys to fire up even when i change to hot water only,

someone suggested a stuck pressure switch is this a simple fix and plumbers around. or any other advice.

should i drain the system to stop the pipes from freezing.

thanks.
