Rainwater harvesting is very popular in South Africa and keeping the water in your tanks clean and debris free is vital if the water is intended for use inside the house. Even with a leaf catcher and a first flush system installed, plant matter, waste & sediment can settle at the bottom of your tank, which enables the growth of blood worms, mosquito larvae, bacteria/protozoa (including E. Coli, Giardia and Salmonella) and algae.

How the EcoDepot Tank Cleaner System works:

The EcoDepot Tank Cleaner System works by vacuuming up these settled contaminants and discharging them every time your tank overflows. Once the water level reaches the height of the overflow, our specially designed flow booster triggers a siphon effect and starts vacuuming water with a flow rate of 4 litres per second (this is more than a 1.1kW pressure booster pump can produce). This powerful vacuum sucks up the sludge & contaminants, removing them from your tank.

Without the EcoDepot Tank Cleaner system installed, every time your tank fills up with rain and overflows, fresh water from the top of the tank is discharged through the overflow while any contaminants that enter the tank can settle and decompose at the bottom of the tank.

The vacuum is broken when the water level reaches a pre-set hole in the pipe, allowing the water level to rise again and begin another cleansing vacuum cycle.

Ask a Question
  • The tank connector has a 50mm BSP thread. The fittings on both the JoJo & ECO tanks have a 40mm BSP thread on the overflow outlet. How do you connect?

    Hi, You need to replace the original tank fitting with the one included in the tank cleaner kit. It should fit exactly for Jojo, Ecotank and most common brands sold in SA. This video shows how to do it (jump t 2min18s to see the part about the overflow outlet:

  • I see Nel tanks are not on the supported list. Can it be modified to work with them?

    We've seen instals on Nel tanks in the Western Cape, it probably doesn't require any modification - if it does, it will be the fitting of the overflow on top of the tank.

  • I have two 2500l Jojo tanks connected in series to each other.Do I need two tank cleaner systems. With the tanks being connected at the bottom to each other, will one system be able suction the dirt from both tanks?

    For the tank cleaner(s) to work, you need the 2 tanks (let's call them A and B) to be at the exact same level, connected by their bottom outlets, and of the exact same dimensions.
    1. I am asssuming that water is collected by 1 tank only (tank A).
    - It is very likely that tank A that has the most dirt at the bottom. Tank A needs a tank cleaner to remove that dirt.
    - Water from the parallel tank (tank B) is not going to be affected by the tank cleaner of tank A. You would need a second tank cleaner to remove the dirt of tank B.
    Note that from what we've seen, tank B is likely to have a LOT less dirt than tank A => we would normally recommend only 1 tank cleaner on tank A.
    2. If water is collected by both tanks separately, you need 2 tank cleaners.

  • how to make a filter to collect sand and leaves in a jojo tank

    To prevent leaves and sediments from entering your water tank, we recommend you combine a leaf catcher and a first flush diverter. Once the leaves and sediments have entered the tank, you can do two things: empty it and clean it, or use this tank cleaner and make the tank overflow to syphon out bottom tank water.
