When you hve bunged the system and think you have closed all the AAVs you still need to release the system pressure before you go cutting into any pipe. You release system pressure by attaching a hose to drain valve and letting water out, if the system is successfully bunged the flow from the drain valve will gradually slow down and stop after about a minute, if not, air is getting in somehow and the system is draining.
Please feel free to ask any questions about bunging the system as it is something i do all the time
Sorry about the typos, just finished my first bottle of wine for the evening
