First Solution: Raise the level of your water butts
If you can't raise the level of your water butts, follow these steps...
(See large diagram below)
Step 1: Ensure you connect at least one water butt at the correct level to your RAINPOD™.
Step 2: Add a 25mm 90 degree overflow bend at the max water level you would like to fill your first water butt(s).
Step 3: Ensure your RAINPOD™ overflow is HIGHER than the water level in step 2.
Step 4: Connect your hose to the 90 degree bend in step 2 and connect the remaining water butts in the lower garden section.
Step 5: Add an addition water butt tap to any of these water butts to access your lower level water or install a water butt pump.
Step 6: Add an overflow to one of these water butts. This will serve as your main overflow to your system.
The built in over flow in the RAINPOD™ will not be in use by using this method.
If you wanted to hide the lower level water butts, simply add a RAINTAP to access your water in a more convenient location.
