Re: How to reduce the maintenance of tank filters ? 5Jun 16, 2021 11:26 am SaveH2O Can you confirm that it is the tank's top meshed inlet screen that is clogging thanks. Yes, it is the tanks top meshed inlet screen that is clogging. There are two inlets, one from the shed (the shed gutters are much higher than the inlet), and one from the house (the house gutters are only a little bit higher). SaveH2O If you are unable to fit leaf diverters to the downpipes due to head loss, the sediment trap will help a lot but it isn't effective with suspended organic matter although lighter organic matter will settle as bed load after the rain stops. The ICON Leaf and Debris Controller is the most effective leaf diverter currently on the market but it does have more head loss than others sold due to its height. On the house, we do have a leaf eater on each downpipe, however, as they have a very fine mesh underneath the wire mesh, these clog up very quickly. On the shed, there are no leaf eater/diverters at all, just PVC from the gutters to the tank inlet. The tank is a Clarke tank and we will never buy one again. Not as strong or not as well made as the Polymaster up on the hill. We pump uphill every few weeks to the Polymaster, for the gravity feed back to the house. The Clarke tank had a huge poly pipe inside for structural reasons, to support the tank roof, yet the pipe has dislodged due to the force of water coming into the tank and hitting that pipe in the middle. Why I mention all that is because the Clarke tank only came with one inlet, so we had to cut another inlet in the tank roof. In hindsight, I would have preferred two smaller Poymaster tanks rather then the one large (45,000 litres I think) Clarke tank. SaveH2O I hope to still be here! Well I hope you are. Are you okay ? SaveH2O You can also cut out a piece of oversized shade cloth (so it forms a saucer shape) and place it on the mesh. It also makes cleaning a lot easier. Okay thanks, good idea. Especially good idea for us, when we need to clean the inlet thoroughly, it means unfastening text screws that are holding the inlet sieve down.

Whoever designed the early leaf diverters that had a coarse outer mesh and a mosquito proof inner mesh must have been having a real bad day! You can convert the old Leaf Eaters like you have to have the mosquito proof mesh on the outside. I am pretty sure that Bunnings sell the kit. I have designed a superior smaller leaf diverter with 500 micron filtration and high drainage capacity but I need to wait until a UV stabilised resin is developed to allow the filter to be SLA 3D printed. It should be possible to design a dry system sediment trap for the shed pipe. Can you post a photo? 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage.

Re: How to reduce the maintenance of tank filters ? 7May 07, 2022 8:55 am Thanks for your reply "SaveH2O", much appreciated. As with many projects, the "squeakiest wheel gets oiled the most" so haven't had the time or energy to get this looked at any further. We have had a few chats about these problems, and as I remembered that doing anything serious with "first flush" or similar systems relied on having sufficient drop in levels, have now at least had the levels checked with a laser level. These are now all recorded, so a small step at least. Re: How to reduce the maintenance of tank filters ? 9May 08, 2022 4:27 pm Yes, I know.The filter screen has too shallow an angle and the larger aperture outside mesh is a failed design. The dominant market leader has mosquito proof outer mesh but its outer mesh also has the same shallow angle PLUS it also has a flat recess at the bottom that traps debris amongst other faults. The ICON Leaf and Debris Controller has a superior steeper outside filter screen but the unit is a conventional rain head shape and taller than the market leader and so everyone bought the inferior market leader because of the lesser head loss, the reason Bunnings ceased stocking the ICON unit. If you use the ICON diverter, you can 'reclaim' the head loss by replumbing the wet system pipe with a sediment trap and divert water directly into the tank via a low restriction inlet that also eliminates the head sapping vertical riser.
