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.
