Re: solutions to overflowing gutter 6May 22, 2015 3:15 am SaveH20, I just checked out your website. You have a great informative site with some products that i never knew existed. There are some great solutions to storm water issues. I am saving your site and recommend all forum members have a good read of the products you have. Re: solutions to overflowing gutter 8May 22, 2015 7:18 am Do you have a filter in it - like in a shower ? We have a tank so the gutters had these filters. No problem until it really poured down. Funny thing was it had a main filter to stop most things - then this smaller filter that the water could just not pass though quickly. If this second filter is removed - you still have the main filter - then the water flows well. We don't drink this water - only garden - so no worries with health. Re: solutions to overflowing gutter 9May 22, 2015 12:07 pm goody59 SaveH20, I just checked out your website. You have a great informative site with some products that i never knew existed. I only research and develop products for myself these days and they are unique because I don't copy other products. The Gutter Pumper is a highly efficient 20 mm inverted nozzle. A standard inverted nozzle is simply a 50mm pipe fitted near the gutter's high point with the top of the pipe rising above the gutter's sole. When the water level rises, it flows into the top of the pipe and invariably discharges to atmosphere. Because a 50 mm pipe presents a substantial obstruction inside the gutter, the BCA requires inverted nozzles to be fitted at the gutter's high point. I am against having devices overflowing to atmosphere because the water falls next to the house foundations. goody59 SaveH20, do you get that vortex effect in a rectangle shaped downpipe? Do you sell just a baffle to prevant the vortex effect to retrofit ontop of standard downpipes? The gutter is drained by a tapered pop that the downpipe fits to. Pops are also known by other names in different States. A 100mm x 50mm pop for example will usually be 92mm x 42mm at the bottom but it is the larger opening at the top that drains the gutter. Because water falls as weir flow, rectangular downpipes also have an air core. As a result and unless the downpipe's flow is obstructed, a downpipe will never have less than 3/4 air. The idea of having a baffle over the pop effectively describes an anti vortex plate but it is not a good idea for downpipes because having a supported flat plate above the pop would present an obstruction that accumulated debris. A pipe draining syphonically also generates negative atmospheric pressure and tougher pipes are used. Saint Mike Do you have a filter in it - like in a shower ? The Gutter Pumper is fitted to the gutter's high point unless there is leaf guard fitted. The high point is what determines the gutter's slope and the roof area drained to each downpipe. Water only drains into the Gutter Pumper once the depth exceeds 5mm and full syphonic flow requires a water depth of 25mm to cover the anti vortex baffle. By the time the water depth exceeds 25 mm at the high point during heavy rain, any debris is long gone. The inlet face is designed with narrow gaps and should a leaf block half of the inlet's face, the device will still operate with 80% efficiency. When the water level drops, the suction stops and the leaf simply washes off. Saint Mike We have a tank so the gutters had these filters. No problem until it really poured down. Funny thing was it had a main filter to stop most things - then this smaller filter that the water could just not pass though quickly. If this second filter is removed - you still have the main filter - then the water flows well. What you have described sounds like a leaf diverter with a coarse (usually about 6-10mm) outer mesh and a mosquito proof inner mesh. Mosquito proof mesh has to have apertures that are less than 1mm (1,000 micron) and 955 micron mesh is commonly used.The problem is that bird droppings and other finer decomposing organic matter fall through the coarse outer mesh and then either wash through or block the inner mesh, causing overflows. The situation is compounded during heavy rain because that is when most debris is washed from the gutters. I am currently doing final prototyping on a very low maintenance leaf diverter that has non meshed surface effect 500 micron filtration. With over 836,000 properties in Australia not on a water grid, the unit will offer higher yield and better first stage filtration than anything else currently on the market. The water savings potential is huge. UPDATE 23/10/22 We were unable to injection mold the filter because its intricate flow paths and surface effects that sucked water through 500 micron passages made building a molding die impossible. We are now considering the viability of commercialising a modified version that can be 3D Printed in ASA plastic but for now, the project is still on hold. 3in1 Supadiverta.

Re: solutions to overflowing gutter 11May 22, 2015 12:45 pm Hi goody59 Syphonic drainage was invented in Scandanavia about 30 years ago and is used to drain large roof areas with smaller and fewer downpipes. The pipes are specially constructed because the high velocity flow creates sub atmospheric pressures within the pipes. If you Google "syphonic drainage" or "siphonic drainage", you will access a lot of information. I have linked a site below that has some nice videos including the 4 priming stages. The third "bubble flow" stage has a 'scouring' (cleaning) action on the pipes walls. The link takes you directly to that page. http://www.hydromax.com/144_HowdoesHydr ... eWork.html 3in1 Supadiverta.
