pot luck mostly on a gravity system open the mot valves to manual can stop air locks.
i try not to drain if ican help it just bung the system saves alot of time.

what do you mean bung the system?

in the f/e tank put a rubber bung in the vent pipe and one in the feed pipe that then creates a vacuum in the system so you can do work on the rads etc and only loose a cup of water.

Im guessing he means bung the pipe that he cuts temporarily until he connects it, instead of draining the full system. this is doable with compression fittings but obviously not soldered.

Its also possible to get freeze kits, these have been suprisingly good the times ive used them. They freeze the water in the pipe solid, so you freeze both ends of the pipe your cutting, then you have about 10-15 minutes before the ice plug defrosts.

edit : no he didnt mean that then , however i see how that would work.

City & Guilds level 2 and they dont teach you the basics of bunging the system.

Next youll be saying you dont know how to backfill a system to get rid of airlocks.

Fill the system slowly, dont allow water to gush into F&E.

Go to your local Plumbcenter and purchase a Backfiller!

It will all become obvious then!!
