Hi we have a tender with a builder and he has on it a water tank with a Vada pump, are these brands any good?
Cheers

Re: Vada water pump 11Jul 11, 2016 8:43 am SaveH2O The only 3 other alternatives would be to either have a large pressure tank (very expensive), a roof tank that could gravity feed but also operate with a small pump when there was power or else have a solar PV system with battery storage. At Bunnings I just spotted 12V pressure pump. I will have a look if I can use it to build in redundancy to run off two car batteries and kick in case of power failure. I am interested in off grid solar but have not yet got around to have a serious look. I hope home storage batteries come down in price soon. I have also spotted $300 constant pressure pump but you get what you pay for.

Well worth having a look at. The pressure tank is set at 20 psi which should draw down slightly more than 6 litres. If you have 6/3 flush cisterns, it should do two 1/2 flushes before the pump starts. If it doesn't quite manage to do two 1/2 flushes without starting, you can simply lower the pressure slightly. Another alternative is to fit another pressure tank in tandem to increase the draw down. I paid $190 for a 60 litre Pressure Wave tank two years ago but that was a good price...the next best price was $210-220. It has made a huge difference because it is used to supplement an existing pressure tank. I am not sure what the current prices are. They have given this pump the best chance of having a long life but fitting the filter and pressure tank. Numerous short start/stops on a strangled pump accelerate pump wear but a pump will operate at maximum efficiency when recharging a pressure tank. Another cause of premature pump wear is when the suction line is fitted to an elbow that is fitted directly to the pump. This is very commonly done. A straight section of suction hose that respects at least 8 diameters should only be connected to the pump. I mentioned earlier that having the tank's pump draw valve fitted at the very bottom of the tank is another very common mistake...but great if you want to draw the worst quality water in the tank from the sediment layer. I am astounded that so many tanks are plumbed like the one below. Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage.
