Re: Water tank and pump configuration 12Apr 28, 2019 9:26 pm aaronmurray1987 Yep have purchased some food grade suction hose, some floats, strainers and stainless steel wire. Reckon the cost for me to make two is less then $100. They were about $240 when they first came out but a lot of places have copied them since but the cheapest is still about $240. When I get time, I'll make them myself and sell them for a more realistic price. aaronmurray1987 This is the one i have bought, it looks very similar to the icon drawing on the icon catalogue website. https://www.bunnings.com.au/rain-harves ... d_p4774053 The problem with the one linked is that solid bird droppings fall through the course outer mesh and wash through the inner mosquito proof mesh. The ICON one is below. It was designed in NZ and the original outer screen wasn't something that I would put my name on. The current outer screen is much better. I have linked an eBay seller below who is charging more than double what the latest version can be bought for in Bunnings. Note the old honeycomb outer filter design! https://www.ebay.com.au/i/252601999957?chn=ps Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ I can't find a photo of the latest screen, only the sketch below. I will take a photo of one tomorrow. Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ aaronmurray1987 Great i will use 100mm for the FFD abd grab some of those brackets from your wesite also. They are not available on the website because they are manufactured in a family die as two non matching caps and if I sell them, I am left with an unusable cap. Just contact me and I will send you some. 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage. Cleaner Neater Smarter Cheaper Supa Gutter Pumper.

Re: Water tank and pump configuration 13Apr 28, 2019 9:27 pm Also have you done a DIY on a tank Vac system, another rediculous price for some PVC pipe with holes in it? Re: Water tank and pump configuration 14Apr 28, 2019 9:40 pm The total cross sectional area of the holes (suction velocity) is vital to match the discharge flow rate plus you have to have a vacuum break at the top of the internal overflow pipe so that the tank doesn't syphon dry. I can make something that will purge the outside pipe to create the syphon easy enough. I have no plans to DIY one though, my Supadiverta system eliminates the need for an overflow pipe and very little sediment builds up in the tank, what is there is like talcum powder, just the settled fine suspended particles that passed through. I intend having the website show a simple plan for a similar floor vacuum that simply connects to a very low inlet that people can open once a year or so when the tank is full and rain is expected. It won't be an overflow, just a simple tank cleaning system. It isn't worth my while selling it as a kit, just easier to show some diagrams. 3in1 Supadiverta.

There are cheaper options such as these, but these do not have a pipe accross the tank floor. It will only take it from one spot. http://www.enter-shop.com.au/catalogue/c2/c13/p108 Re: Water tank and pump configuration 16Apr 29, 2019 11:33 am I have a very simple tank cleaner design that is like a vacuum head that you push slowly over the floor and it works well. In time I will have it on the website at a cost including postage that will be cheaper than someone buying the parts and then having to calculate suction angles and velocities. You can fit a simple and inexpensive DIY sediment trap to a non turbulent section of 100mm DWV wet system pipe that will capture the bed load and discharge it manually through a reduced sized pipe. Bed load is settled suspended sediment and heavier debris that clumps in 'colonies' on the bottom of the pipe but when it travels and comes to the sediment trap, it simply falls down the 'hole'. The trap not only dramatically alters the amount of sediment that is common to rain water tanks, it also alters the type of sediment to something that resembles fine talcum powder. Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ We now use an invert taper and not a pipe reducer to downsize the pipe because the pipe reducer retains some sediment at the bottom below the outlet. Reducing the pipe size increases the velocity, decreases the flush yield loss and allows the purchase of a smaller and cheaper valve. A 40mm DWV pipe holds roughly 1 1/4 litres per metre. There is usually a low restriction inlet fitted and this is closed when the collected bedload is flushed. A one year summary of a 4 tank system that used this sediment trap is linked below. See post 61. The happy home owner also made the above diagram! Thanks John. viewtopic.php?p=1146540#p1146540 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage.

Re: Water tank and pump configuration 17May 09, 2020 11:57 am Here's how Ive done my rain water system. Its similar in terms of have 2 tank sites and transfer between. Im lucky not to have leaf problem. Northern Adelaide, Format Homes '16-'17 after failed Bondor OB Building Standards; Getting It Right! Thank you for the generous offer. I need to get the plumber out to give me an explanation. As mentioned I haven't seen any rain water discharge from pipes 1& 3. It… 7 10834 If you can calculate the reasonable charged head from let's say 100mm below the gutter to the top of where the vertical riser's horizontal discharge pipe will be, that… 11 17539 Can a plumber put a tap on a rain water tank which is full? Tank is similar to one in photo. Cheers. 0 1670 |
