Re: Rainwater tank issues 18Feb 16, 2018 11:52 am Monty4 Sorry, probably a silly question......but "IMHO"? In my humble opinion. Monty4 The top of the bell mouth still needs to be as high as the top of the horizontal pipe exiting the tank. Looking at the arrangement at the top of my tank, I can't see how the bell mouth would fit under the top of the tank. The return vertical pipe should only come up as high as the overflow's invert as a maximum. A small drain hole would need to be drilled at the pipe's lowest point. PVC becomes malleable when heated and you could mold a bellmouth of sorts from a fitting (easiest) or the pipe. There are videos on You Tube showing how to do this. https://www.youtube.com/watch?v=fzdnlBkG2mI A big possible/most probable problem is with the tank's design and the inflow pipe...the overflow's extended internal orifice obviously cannot be under the wet system flow path. This is why I have been thinking of an internal extended short horizontal pipe or fitting with part of the bottom section cut out (or drilled with holes) but it too can't be impacted by the inflowing water because of the stress on the fitting. The pipe or fitting needn't be long though. 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage. Cleaner Neater Smarter Cheaper Supa Gutter Pumper.

In consultation with our builder, it was agreed that he would reduce the roof catchment being diverted to the tank to the northern roof area only (about 1/3 of what it had been). The charged underground system now has a screw cap in the storm water sump that can be removed to allow the system to be flushed. We have had a few torrential winter downpours since this modification and no tank over flows ! Yeehah!! Clearly the cost has been a reduction in the catchment and we will spend more often over the dryer months with an empty tank, but we are happy with the outcome that we have got to overall. Many thanks to SaveH2O for your valuable advice. Re: Rainwater tank issues 20Jul 16, 2020 10:20 pm My wife and I have just moved into a house with 3 x 3000 litre water tanks in Heathmont VIC, and almost zero knowledge of them. Almost all of this thread goes over my head. We had a plumber do some other work on a toilet and determined that 2 of the tanks are joined together, and feed the toilets and laundry via a pump and tank to main auto changeover switch, although the pump was unplugged when we got here. There is also a tap that appears to make the tanks feed the entire house, this was open, even though the pump was off. That tap is now off for the moment. Inlet filters on the top of each tank had a couple of cms of sludge plus a ton of leaves and other much. I have cleaned them and we are now using it for toilets and laundry, and looks/smells clean to the eye/nose. Can someone reccomend a tank specialist to come out and assess the entire system and give us some advice on it. We would be interested in if it can be used for showers and/or hot water and issues with that. 18 90357 DIY, Home Maintenance & Repair But if it is a ground level open pit, then it is not a charged system. No surprises there. The pipes have obviously been altered and there would be a reason for this.… 3 31230 Grate, thank you!
