Very glad of that, as a local supplier would only have only sent a driver. Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ the 40mm will be dug in at the end of the path. To the left of the central inlet is the CFA outlet and fittings. The "standard" top meshed inlet is immediately above the 50mm central inlet but there'll be no riser, just the 40mm uPVC feed. Quote: We use 40mm wye junctions but they are hard to find The sediment trap will be using the 40mm wye as the online shop you mentioned in WA did have some and were able to sell without me being "in the trade". Might be a new policy, didn't ask. trying to control costs, I've kept the smaller Pondflex. Quote: That's good but are you sure that 1 metre will be long enough? With the tank in place, I've set up a dummy run on the inlet. From right to left, 40mm 45º angle, at ground level from the main 40mm pipe. a little masking tape in place of short inner 40mm pipe, to a threaded adaptor ( faucet??), into a Poly Director and the Pondflex. Another Poly Director, then a slightly different adaptor, and another 45º elbow, which is is angled for height as well as turn. yet another threaded adaptor and a 40mm to 50º adaptor into the inlet valve. I hope this will be sufficient in rising the 300mm or so. the 40mm poly underneath will be the centre outlet of the 3 Supadivertas, feeding the pit, which also has 2 aggie drains and the channel drain from the path. Once settled, the poly may be replaced by the proper Supadiverta flush devices but for the moment these are on hold due to the multiple step construction required, and the myriad of other works concurrently underway. Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ The tank was provided with an overflow and cap. I intend to use solvent to fix the cap in place, in order to allow the tank to fill even higher, unless there's a problem in doing so? If it's OK, I've marked around walls etc to set the upper part of the overflow to match the overflow level of the Supadivertas, that being the line of the web address. Further delays with builders, roofing plumber and the project plumber are likely to see a wait of another 3 weeks before any further progress.. Re: Tank - 3rd try 13Apr 25, 2016 10:58 pm That is a very neat low restriction flow path and no vertical riser or overflow pipe to really confuse your visitors...it always does!!! You will have very good quality water in the tank but I do have a very big query...is the very low drain outlet on the RHS intended to supply the pump? If so, it is fitted to draw water from the anaerobic zone...it is fitted very, very low. I consider that not to be best practice. We would normally fit a faucet socket straight to the 40mm PVCu supply pipe but maybe you need the 45 degree elbow for alignment...I can't tell from the photo. It also looks like a 90 degree faucet elbow would have been better than a 45 degree elbow at the tank's inlet valve but again I am not there to see it in real life. You can also use nyglass threaded elbows and these come in different M-F combinations. The one that I have posted below is obviously a F-F. Nyglass threaded fittings are more compact than pressure pipe fittings but they can be exxy. Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ You will almost certainly need a check valve between the pump and the tank. I wouldn't use solvent to fit the cap to the overflow outlet, just use a tad of silicone on the cap's outside edge. The cap will be under no pressure. Is there enough room to fit the CFA hose? Regarding the sediment trap at the second tank...the water will be unfiltered and fitting a tee at the inflow pipe's lowest point (base of the vertical riser) will serve as a good trap. The principle is very simple. 3in1 Supadiverta. Rainwater Harvesting Best Practice using siphonic drainage. Cleaner Neater Smarter Cheaper Supa Gutter Pumper.

I neglected to mention that outlet, which was an error by the manufacturer. For CFA purposes, the outlet was ordered at above the 10,000 litre level, at 1,100mm. They will be travelling here to rectify the problem, and instead of the 25mm outlet, will put in a 32mm one to match the same gauge Metric Poly pipe and fittings. Quote: We would normally fit a faucet socket straight to the pipe but maybe you need the 45 degree elbow for alignment.. It took some juggling to arrive at the inlet configuration, and the 45º at both ends so it aligned with both ends. Quote: You will almost certainly need a check valve between the pump and the tank.

Quote: Regarding the sediment trap at the second tank...the water will be unfiltered and fitting a tee at the inflow pipe's lowest point (base of the vertical riser) will serve as a good trap. The principle is very simple. The second tank currently has the Tee system. It has proven effective, though a couple of issues make it awkward in use. The ball valves are quite low, and given that the tanks surroundings are on sloping dirt, and bending is difficult for me, makes it tricky. Supporting the Tee and with 3 metres of unsupported horizontal pipe has meant a lot of weight in both pipes, and several re-adjustments due to lack of a "frame" under them all.That's why I am considering the Wye option on the 2 horizontal pipes, with a custom support system. The valves would be much easier to access this way. I've got 2 PVC Stepped Reducers, which go down to 40mm, if that's sufficient to then add small pipe and ball valve. Re: Tank - 3rd try 15Apr 26, 2016 10:07 am ![]() I neglected to mention that outlet, which was an error by the manufacturer. For CFA purposes, the outlet was ordered at above the 10,000 litre level, at 1,100mm. They will be travelling here to rectify the problem..... I completely overlooked the detention requirement and the necessary minimum height (1.1 metres) of the pump's draw valve. ![]() I hope that the manufacturer doesn't supply tanks to their customers with the pump outlet fitted as low as yours, their other customers won't have negligible sediment like you. Your 'sediment' will be more like a fine powder, totally different to what normally goes into a tank and very easy to syphon vacuum if you ever get the urge many years down the track. Tank manufacturers also invariably fit the tank's top meshed inlet immediately above the pump's draw valve. I have never worked out the craziness of this 'logic' either. ![]() It took some juggling to arrive at the inlet configuration, and the 45º at both ends so it aligned with both ends. Looking at it, I would use a nyglass 90 degree elbow and a straight run of hose but I say that without the benefit of being on site. ![]() By the way I've stretched the budget with a Grundfos CMBE 3-62 pump. It's a good sized quality energy efficient pump, a very good choice for you. ![]() The second tank currently has the Tee system.

Re: Tank - 3rd try 16Apr 26, 2016 1:41 pm once again your comments and the time spent are greatly appreciated. I hope the final installation makes it all worthwhile. Quote: Looking at it, I would use a nyglass 90 degree elbow and a straight run of hose but I say that without the benefit of being on site. I'll see if I can get one locally on a trip to town, as it'd be uneconomical as a one off online buy with added freight costs. I had put the 45º elbows in as I'd believed this was part of the design philosophy, and thought I'd seen in mentioned in more than one article as a means of reducing turbulence. A cursory search found one thread where it was discussed, and have a vague memory of it being mentioned when taking off from a system with a full vertical riser. There are only 2 x 90 degree elbows elsewhere on the horizontal flow path. The vertical pipes down from the Supadivertas have 45º elbows, and the Tee on the horizontal path is twisted to "meet and match" that angle, eliminating the need for a 2nd 45º elbow. Quote: Note that the term “low restriction inlet” references the smaller pipe’s flow path. You need to use 45 degree elbows rather than 90 degree elbows to reduce turbulence and Pondflex UV stabilised hose or similar should be used as a reasonable length of flexible coupling. Quote: I hope that the manufacturer doesn't supply tanks to their customers with the pump outlet fitted as low as yours, I did find the manufacturer to have an excellent Customer Order form that allows detailed specifications to be provided. They also require you to re-confirm prior to production. This appears just to have been one that slipped through. - to avoid naming names I've sent the form as an attachment to your commercial email - [quoteI can't quite follow the rest of the explanation in your previous post but yes, pipes do need to be supported.][/quote] there's a pic on the final post of an earlier thread that gives an idea of the layout. I think since then I add one or 2 star pickets near the Tee junction. i now have a fair amount of offcuts of timber and steel to eventually create a solid structure along the horizontal feed, and that location will also enable far easier access to a sediment trap valve(s) on each pipe. http://forum.homeone.com.au/viewtopic.php?f=35&t=72079 Re: Tank - 3rd try 17Apr 26, 2016 2:26 pm ![]() I had put the 45º elbows in as I'd believed this was part of the design philosophy, and thought I'd seen in mentioned in more than one article as a means of reducing turbulence. Yes, it is and you are correct. A 40mm 45 degree elbow will save about 0.7 metres of equivelent pipe length in friction loss as opposed to using a 90 degree 40mm elbow but you have two 45 degree elbows plus additional fittings. To keep it neater and simpler, I would just use a 90 degree faucet elbow and a straight hose for your situation but if you are happy with the current connection, then just use that. What I want people to avoid doing is plumbing two 90 degree elbows, one at the outlet connected to a vertical pipe and another 90 degree elbow at the bottom of the pipe as this generates unnecessary friction loss and turbulence. It is much better to use one elbow at the valve and then connect a flexible hose to the horizontal pipe. If the pipe comes in from the side as yours does, using a threaded elbow is neater. You cannot buy a 45 degree threaded elbow as far as I know. 3in1 Supadiverta. Rainwater Harvesting Best Practice using siphonic drainage. Cleaner Neater Smarter Cheaper Supa Gutter Pumper.

Re: Tank - 3rd try 18Apr 26, 2016 9:42 pm All good, now have a better understanding and will grab a 90º 50mm elbow, and convert down to 40mm on the vertical drop into the Pondflex. Quote: You cannot buy a 45 degree threaded elbow as far as I know. But you may make your own when you have your 3D Printer setup. ![]() Re: Tank - 3rd try 19Apr 26, 2016 10:23 pm You already have a 50mm x 40mm M M reducing nipple fitted to the inlet, you only need 40mm fittings. You have two best options. Because you can only buy 90 degree PVCu faucet elbows (female thread at one end only), you can use a 40mm faucet adapter to fit into a 40mm faucet elbow to provide a female thread at one end for the director. The easiest and neatest way is to use a nyglass F F elbow like the one I posted as this will connect to the reducing nipple and the director. If you already have a 40mm faucet adapter, then your easiest way is to use the faucet elbow + faucet adapter combination. If you are happy with what you already have, then go with that. I am only referring to aesthetics here. Do you have your own 3D printer? I have all of my prototyping done on 3D and have done for 10 years now. It's all done in nylon. 3in1 Supadiverta.
