Flow & Return or Return & Flow Centrral Heating
Had a calamity the other day when we found that we had a leak in our
central heating system pipework.
In the excitement (!) to dig up the tiled bathroom floor we MAY have
managed to reverse the polarity of the two pipes concerned that feed
from the boiler.
Does it matter which way round the water flows through the system ?
Is the there any simple way to discover if I have them the wrong way
round ?
Thanks
