RAINPOD™ is a gravity-fed system, so the ground under your water butts matters. See what happens on level, higher and lower ground, and the simple fix for each.
In most cases this is the ideal setup, with level ground from your drainpipe to your water butt(s). Keeping your RAINPOD™ "funnel" slightly lower than the top of your water butt means excess water goes back into your drainpipe through the built-in overflow, instead of overflowing your water butt.
As your water butt fills, so will your RAINPOD™, and the water levels will always be the same. This is because the system relies on gravity, also known as a gravity-fed system.

This shows what happens if the water butt sits where the ground is higher than your RAINPOD™.
The water in the water butt will only rise to the level of the built-in overflow, at the same height as the "funnel" section at the top of your RAINPOD™.

In this case, simply raise the height of your RAINPOD™ until the built-in overflow is slightly lower than the top of your water butts. This works depending on how high you need to raise it, as your tap may become hard to reach.
This setup suits any water tank or water butt up to 1250mm tall, which lets the top of the tank sit slightly higher than the built-in overflow on the RAINPOD™.
If this isn't an option, we can build you a custom extended version. Please get in touch for this option.

The water butt will fill up and overflow. In this case we recommend drilling a hole near the top of the water butt and attaching an overflow pipe.
The flow from the RAINPOD™ tap will be slower here because of the lower water level.

First solution: raise the level of your water butts. If you can't, follow these steps (see the large diagram below):
The built-in overflow in the RAINPOD™ won't be in use with this method. Want to hide the lower level water butts? Add a RAINTAP to reach your water in a more convenient spot.
Lower ground levels: the full solution with a 25mm overflow bend and a main overflow on the lower butts.
