If so, the capped pipe might be someone's idea of a charged system's inspection opening/flush outlet. I can only guess at this one. 3in1 Supadiverta.

It looks like an inspection point. So is it normal that there is full of water in it? A large amount of water came out when I opened it. Re: Rainwater Tank Wet System - DWV outlet 4Mar 22, 2021 6:14 pm It will be part of the charged system and water in the downpipes will be the same height as the tank's vertical riser. Every 1 meter in a water column generates 9.82 kPa pressure. Because a standard wet system divert downpipes and the stormwater system is altered, the small capped riser may once have been an inspection point on the annexed original stormwater system. 100mm DWV pipes are sometimes used for stormwater and charged systems, they are certainly much more robust than the thin 90mm pvc stormwater pipes. 3in1 Supadiverta.

Thanks for your help mate Re: Rainwater Tank Wet System - DWV outlet 6Jul 12, 2022 8:50 pm Just revisited this thread by accident. Stormwater pipe regulations factor a 1:100 year storm event to facilitate the pipework having to also accept surface drainage and water from silt pits that ag pipes connect to, The cover may be capping a previous stormwater surface drain that was left connected in case the wet system ever blocked so that access would be more readily available rather than having to dig up the paving. Using it as a flush outlet would be messy. 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage. Cleaner Neater Smarter Cheaper Supa Gutter Pumper.

But 1st i'll need to read about NRV cleaning/replaing stuff. I… 7 31940 That's brilliant would appreciate if you have you can locate the other doc so I can use it with my discussion with the building surveyor 10 1437 Once you know the basics, the rest is easy.
