Re: Drainage issues - Can someone please help.... 17Apr 16, 2019 12:13 am An additional fact that you need to know to understand the system is that the friction loss expressed as equivalent pipe length of the pipe between the pit and the intersecting junction is about 46m. A 250 mm water level above the pipe's invert in the pit will provide a maximum flow rate of about 390 lpm provided that the intersecting water through the junction has good velocity and (I think) not act as a flow restriction that the current slow flow from dp 1, 2, 3 & 4 does. The real life pit to kerb figure will be less than this because of the flow restricting and volume reducing entrained air produced from jetting water in communication from dp5 and dp6 to the stormwater pipe (the same cause of the bubbling you have seen in the pit) and also from the additional intersecting water in the junction and the remaining pipe to kerb, the reason why achieving good stratified flow velocity from dp1, dp2 & dp3 will be vital. There will be some minor pipe slope between the junction and the kerb. There would be no air entrainment generated by the 32mm valve because it would operate under full flow conditions but fitting an air release valve further along the storm water pipe will need consideration. There are also a couple of other but similar variations to my initial suggestion. NOTE: The surface level at the junction is 200mm lower than at the pit but we don’t know what the pipe’s depth at the junction is. The plumber however has said that the cam showed ponding in the pipe and it would be expected that the pipe depth at the junction was not as deep as the pipe level in the pit. No allowance for any additional (unknown) pipe slope was made in the head/flow calculations but some minor additional head should be reasonably expected. 3in1 Supadiverta.

Need more photos from around the house including your gutters. We have had 3 of the wettest years in a row for some time so that wouldn't be helping 3 5427 Hi there everyone i was hoping to get some details and some clarification on some potential defects that may have occurred our recent bathroom renovation. 1. There seems… 0 5239 That's very helpful, thank you. I was mostly interested in knowing if a spoon drain requires a specific slope, but I appreciate the extra information. 4 3820 |
