Re: yet another rain water setup questions 26Aug 27, 2015 9:51 pm just an update slabs poured but got hit with a massive extra for foundations so have cut alot of stuff back. that also means normal pump. and very small pressure tank will still be doing sediment traps but that's about it until i get some more funds Re: yet another rain water setup questions 27Nov 25, 2015 9:04 pm tanks just delivered needing to sort out some flexible hose for the tank to pump. where's the best place to buy some of that pond flex hose? im looking for 40mm and would need some hose clamps are there special ones for that type? Re: yet another rain water setup questions 28Nov 25, 2015 10:49 pm Clearpond Pondflex hose is available at most irrigation stores. They will usually have rolls of different sizes that they will cut to length for you. http://www.clearpond.com.au/products/al ... ccessories We use it mainly to connect to a wet system low restriction inlet. I don't know what the pressure rating is and I have never used it to connect a pump to a tank, that is something that you would need to check. What length of hose would you be looking at? The 40mm Pondflex is expensive per metre. Blue Stripe poly pipe is the usual choice for your intended use. Note that Blue Stripe is measured as an outside diameter (OD) and comes in different pressure ratings. Your requirement would have an internal diameter (ID) of about 35mm. You might find it difficult to find an irrigation store that will cut a Blue Stripe roll to size but if you require a reasonable length, then it may be cheaper to buy a roll because they usually charge more per metre when they cut to size. I think that the 40mm Pondflex has an ID of 38mm but I am not sure, you would need to check. The spiral clamps are shown in the link I have pasted. I assume that reducing friction losses over a long run is your focus, have you considered using 32mm pipe? Most house fixtures are low flow and the 32mm Blue Stripe pipe you would require has an ID of about 28mm due to it's wall not being as thick as the 40mm pipe. A bit of news about the leaf diverter that I am working on. I have developed a superior 500 micron aperture, high yield, low maintenance filter but the body's design has not yet been finalised. It has proven to be more challenging than anticipated to keep the body as small as possible when using our filter but we are still hopeful of proceeding to manufacture. The project however is behind schedule. 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage. Cleaner Neater Smarter Cheaper Supa Gutter Pumper.

Re: yet another rain water setup questions 29Nov 26, 2015 6:22 am If that's the case can i just use 40mm rural poly? as between tank and pump only has tank volume pressure. where blue line is pressure rated and cost more I thought I would need to use something a bit more flexible especially for plastic tanks good news your leaf diverted Is getting there. Good things take time. can't wait to see it in production. Re: yet another rain water setup questions 30Nov 26, 2015 2:02 pm The blue line fittings are cheaper but you won't be using many. The rural Green Stripe is also measured as ID and so the nominal diameters for both pipes are not strictly comparable. Flexible couplings/hoses should always be used. Still have the fingers crossed on the leaf diverter, it will make a big difference but there are no guarantees at the moment. If it can't be kept small, it won't be manufactured. 3in1 Supadiverta.

Re: yet another rain water setup questions 31Jan 22, 2016 6:32 pm ok so things are getting very close to move in. what a hassle i have had with everything! builders plumbers the bank it just goes on just can't take a trick . I have a few check valve (non return valve, one way valve) questions is it normal to have a check valve straight after a ball valve from the tank? - must there be one there? the only reason i can think of is to keep the pump primed is it normal not have a check valve at the house where the ball valves are to switch between bore and rainwater for the house? This means - if both taps are accidently left on i can basically push bore water backwards through the dedicated rain water pipe and contaminate the rain water (drinking) or push (precious) rainwater back through the bore pipe and will go to anywhere the pipe runs eg. outside watering and irrigation ie. waste it. - say i accidently cut a pipe anywhere after the check valve on the pump (so basically any piece of pipe) i can lose all water out of the house, hot water and tank as there's nothing stopping any of it from not returning (i can understand i cant stop the tank from losing water but a well positioned check valve could stop everything else) i cant see that as a good design also i dont have a check valve on the hot water system i can see theres one on my old house. I thought it was required? - that means that turning the water off and draining a cold water pipe can drain the whole hot water system imo i need 3 check valves they have installed 2 of which both appear to be in the wrong location and one on the HWS am i correct or have they done the bare minimum required by australian standard? Re: yet another rain water setup questions 32Feb 01, 2016 12:03 pm B-Man is it normal to have a check valve straight after a ball valve from the tank? - must there be one there? the only reason i can think of is to keep the pump primed If the pump isn't flooded and the tank's water supply can drop below the level of the pump, then a check valve should be fitted. People have also had unexpected high water bills when an automatic switching device has pushed mains water back into the tank and the tank has then overflowed to the stormwater. A check valve should prevent this. Your other questions are plumbing questions, I am not a plumber. Some councils also over-rule some plumbing regulations or add additional mandates, therefore I am reluctant to give an opinion, particularly in the absence of diagrams. 3in1 Supadiverta.

I recommend you read the first few posts in this thread as I tried to make it easy for someone to copy it and fill in there own information Can a plumber put a tap on a rain water tank which is full? Tank is similar to one in photo. Cheers. 0 1668 Hi, does anyone have any experience with using Trex rain escape or EPDM rubber to waterproof a deck so you have dry space underneath.
