I hope that the pump has a cover that you have only removed to take the photo. If the cover is subject to direct sunlight, just make sure that there are holes for cross ventilation on hot days. The Einhell pump with the 20 litre pressure tank is now $299 at Bunnings which is still a good price but the original $249 was an absolute steal. They have done everything to ensure that the pump has an easy life and I have yet to hear any complaints. akapacker I did buy a mainrain changeover valve, but I will install this a bit later or not at all. My plumber called up the Victorian plumbing auditor about installing a manual changeover valve with a water tank, and the auditor said that I needed a regulator worth a cool $1000 to prevent backflow into the mains system, if the pump goes wrong. So my toilets are only on rainwater at the moment, but with 10kL, this is not a pressing problem in Winter in Melbourne. If the rainwater is diverted to the cistern(s) via a separate pipe, the isolation valve and the air gap is all you need. If rainwater is plumbed into the house mains water pipe, you need a couple of check valves, that is all. A "regulator" generally refers to an electronic controller like you would find on an automatic switching device, it sounds like you have been told that you have to have an electronic switching device fitted to a manual control...which is absurd but I can't think of any other possible explanation. I don't understand how your rainwater is plumbed to the toilet cistern(s) given that the cistern(s) are not supplied by mains water yet. Is it a direct connection via a dedicated rainwater pipe to a second cistern valve as shown in the diagram below? http://www.vba.vic.gov.au/__data/assets ... sterns.pdf Does the water pass through a silt pit before entering the underground tank? It is a good idea to have one, they are inexpensive and easy to fit. http://rainharvesting.com/product/filter-pits/ I don't know how you would go making a floating inlet for an underground tank but if you do, you have to keep the inlet about 200mm under the surface to avoid drawing a free surface vortex that will deliver air to the pump. Not good! 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage. Cleaner Neater Smarter Cheaper Supa Gutter Pumper. A low cost syphonic eaves gutter overflow solution. Re: Water tank pumps.... 18Jul 07, 2016 1:31 pm Thanks SaveH2O! Oops, maybe I had better put a cover on the pump. It's just sitting out in the rain, because I assumed it was weatherproof. Could be a $300 mistake! Doh! Each toilet has its own green rainwater pipe going to it. The pipes all go back to a single point, outside the house, and near the water pump. There is also a mains water point next to the rainwater point, but it is stopped up and unconnected at the moment. Before I build the deck, I will get the plumber back to install the changeover valve, to switch the water to the toilets from the water tank to the mains supply, as well as an isolating valve, to prevent back flow into the mains. Thanks for your help! Cheers David Re: Water tank pumps.... 19Jul 07, 2016 2:06 pm Hi David, It isn't the pump so much, it is the electronic controller that you need to protect but it is still wise to protect the pump. Not all pumps are water proof. What area are you in? There is a water tank manufacturer near me, they also make accessories including pump covers and they sell direct to the public at big savings. If you do connect to the mains water, the plumber will also need to fit a check valve, is this what you meant by "isolating" valve? Did you find out any more about the $1,000 'regulator' you were told you 'had' to have? What size is the tank? I forget...sorry. 3in1 Supadiverta.

Re: Water tank pumps.... 20Jul 12, 2016 6:11 am Hi SaveH2O, I am in Camberwell. I had intended on building a roof over all that equipment at a later date, when I build screening for it. But, it's not hard to chuck a bit of plywood over the top of it now. Thanks for the advice once again! My plumber was awesome and helped me out here. I don't need a regulator, because the tank is only plumbed into the toilets, on a separate mains water circuit. The tank is 10kL, and would be full now, after all the rains we've had!
