Re: Rainwater system install - Perth 17Sep 03, 2021 10:08 am You know more than the plumber does about this subject. Are you trenching and fitting the pipes or is the plumber doing it? If you use mosquito proof leaf diverters on downpipes 5-12, you could also use 65mm or even 50mm DWV pipe for the initial pipe lengths as no large objects will reach the subsurface pipe. The 65mm pipe has an internal diameter of 63.6mm that provides a volume of 3.2 litres per metre which would require an unobtainable 77 lpm to achieve a velocity of 0.4 metres per second but its use would be better than the 80mm pipe. The 50mm pipe has an internal diameter of 51.5mm that provides a volume of 2 litres per metre and so a velocity of 0.4 metres per second is attained at 48 lpm. This equates to a rain intensity of 1.8 mm/min for your average size roof area. Standard gutter flow along the bottom of a stormwater pipe requires a design minimum flushing velocity of 0.7 metres per second but larger heavier objects fall down open downpipes not fitted with mosquito proof filter mesh. The video linked below may interest you as it demonstrates different types of debris transferred along a flooded (charged) pipe line. Unfortunately it doesn't use dye to verify laminar flow nor use fine sand spread along the pipe but it is a good video nevertheless. https://www.youtube.com/watch?v=c1xX90ZfBj4 The standard mosquito proof leaf diverters use 955 micron mesh but I have a as yet unreleased compact leaf diverter with intended 500 micron filtration. I have previously mentioned this in the past on this forum and while a 2016 release was the intended goal, the filter screen which includes surface effects can't be made by injection molding. Right now I am waiting for new product developments in SLA 3D printing that include a suitable UV stabilised resin and while the technology is advancing at a rapid rate and there have been many new resins released lately, I am still waiting and commercialisation is unlikely to happen soon unfortunately. The only current leaf diverter that I recommend is the ICON Leaf and Debris Controller. Being larger than others, it loses about 70mm more head when compared to the market leader but this would not be an issue with DPs 5-12. 3in1 Supadiverta.

Re: Rainwater system install - Perth 18Sep 03, 2021 9:04 pm The trench is dug and I plan to do the pipe installation myself. The roof has stainless gutter guard installed with access hatches for cleaning and maintenance. Id did have a thought of also installing some mosquito mesh cut to size and install it inside the gutter over the top of each DP outlet, essentially giving me a dual barrier for debris. Have you seen this done before? Re: Rainwater system install - Perth 19Sep 03, 2021 9:23 pm DIY-DAN The roof has stainless gutter guard installed with access hatches for cleaning and maintenance. Access hatches are essential yet commonly overlooked in the design. Well done. No problem then if you use subsurface pipe smaller than the downpipe for all initial runs and then upsize just before the second DP on the run. DIY-DAN Id did have a thought of also installing some mosquito mesh cut to size and install it inside the gutter over the top of each DP outlet, essentially giving me a dual barrier for debris. Have you seen this done before? I don't recommend it. It isn't needed for your set up and is only asking for trouble. It must also be remembered that most gutter debris is flushed from the gutter during heavy rain. It reminds me of the early leaf diverters that had a course outer mesh (about 8mm apertures) and a small inner mosquito proof mesh. They constantly blocked and overflowed, particularly during heavy rain,,,a bad idea proven! Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ 3in1 Supadiverta.
