hot water wont run after draining system to carry out a repair

plumbing faults

if your domestic hot water wont run after you have drained the system an almost certain remedy is very symply if your cold is running and you have a mixer tap unit block the outlet firmly a cloth on the palm of your hand is usually enough and open both taps the cold will force the air lock back up the hot to the expansion tank a minute or two is usually enough then the hot should start to run if you dont have a mixrr tap unit you will need a short piece of pipe or may be a garden hose to join the hot and cold and this should do the trick

This Works! Thanks man for saving me a plumbing bill.You have to push back the cold water hard with a good seal with a cloth and you will get wet but it works.
