Air testing above ground drainage pipework - Building Regs H (4K). 

Thank you for this. Presumably the 38mm WG is not enough pressure to displace the water you put into traps to seal them. Good tip on placing the manometer on a board to prevent kinking.

Has anybody invented the long reach donut plug so you dont have to reach down into a stinking drain?

You’re the best ❤

Hi Great video. Where can I buy the testing equipment from?
