Job for my father so not charging. Nah no probs draining down and filling is easy there never have any problems with air locks it's a bungalow with surspended timber floor so pipe work just goes down from combi primary's shoot across the bungalow under the floor and rads are just teed off the primary's. I'm just interested to know. That's a shame as I'm not GSR so I can't remove the boiler case to shut the AAV so I have to drain down ha.
