Temp Posted March 9, 2022 Posted March 9, 2022 Oh sorry I miss read your question. For some reason I thought you were talking about pressure testing the drains. Face palm.

dpmiller Posted March 9, 2022 Posted March 9, 2022 the MIs for mine stated to keep it bagged til all building works were complete, anyway.
Dan F Posted March 9, 2022 Posted March 9, 2022 (edited) We just had a final air test done and result was a fair bit worse than last test after first-fix. Thinking about this last night, it is almost certainly all the AAV's we have! We have 4x50mmm AAV's in the warm loft and couple of mini-AAV type things in the plant room for condensates and a pressure relief valve. Edited March 9, 2022 by Dan F
