How to install the EcoDepot Tank Cleaner System For Rainwater Tanks

How does the Tank Cleaner System work?

The EcoDepot Tank Cleaner System For Rainwater Tanks works by vacuuming up settled contaminants from the bottom of your tank and discharging them every time your tank overflows. As soon as the water level reaches the height of the overflow, our specially designed flow booster triggers a syphon effect and starts to vacuum water at a flow rate of 4 litres per second (that is more than a 1.1kW pressure booster pump can produce).

The powerful vacuum sucks up the sludge and contaminants, removing them from your 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 start another cleansing vacuum cycle.

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

How to install the EcoDepot Tank Cleaner System

Step 1
First measure the diameter of the rainwater tank. If needed, cut the vacuum pipe extension so that the length of the complete vacuum pipe (end cap, pre-drilled vacuum pipe, coupler, pre-drilled vacuum pipe extension and elbow) matches the inside diameter of your rainwater tank.
Next, glue the components together, and wipe off any excess glue.

Step 2
Remove the current fitting of your overflow and replace it with the tank connector. Make sure it is a tight fit, but do not push through to the inner ridge.
Alternatively, if you do not have a current fitting, choose a point that is near to the opening to drill a hole for the overflow. The hole should be drilled on the second groove from the top.

Connect the syphon breaker fitting to the tank connector on the inside of the tank (but do not glue yet).

Step 3
Cut a piece of 40mm PVC pipe to connect to the vacuum pipe (which is situated at the bottom of the tank) and to the syphon breaker (situated near the tank overflow at the top of the tank). Measure from the base of the tank to the tank connector on the inside of the tank.

Then, glue the plain PVC pipe to the elbow of the vacuum pipe.

Step 4
Place the assembled vacuum pipe and plain PVC pipe inside of the tank. The vacuum pipe should be placed at the bottom of the tank.
Glue the plain PVC pipe to the syphon breaker. The syphon breaker should face the direction of the outside of the tank. Then glue the syphon breaker to the tank connector.

Step 5
Next glue the syphon pipe with the flow booster to the tank connector, which will be placed on the outside of the tank.
