Simple explanations for plumbing problems

Radiator cold at top,hot at the bottom

Most radiators have a standard sized key, take this along with a cloth to the radiator.  Place the cloth behind the radiator to protect the wall put the key  on the bleed point give it a gentle turn anti clockwise until you hear air coming out. Stop turning as soon as you hear the hiss of the air leaving the key on the bleed point.  When water starts coming out turn the key clockwise to reseal the bleed point.  Remember the bleed point only needs to be turned until it is just tightened up.   Its only made of brass so turning it hard will snap it off in the radiator causing more trouble.

Remember to check the pressure on the boiler when you are finished bleeding radiators if you have a sealed central heating system.
