●
The basic rule of thumb is that you need 100 GPH of flow for every 1 in. of width for your waterfall.
○ Example: if you have an 16 in. wide waterfall and the waterfall is at a height of 8 ft., then you need a pump
to be able to deliver 1600 GPH at 8 ft.
●
If you prefer a more subtle flow of water, cut the flow rate in half, making 50 GPH your target for every 1 in. of waterfall width.
●
If you prefer a more robust flow of water, double the flow rate, making 200 GPH your target for every 1 in. of waterfall width.
●
Don't forget to take friction loss into account when selecting the pump. Remember, this results from bends in the water flow such as an
elbow or bringing the flow through a pressure filter prior to delivering to the waterfall. For this reason it is recommended to use a
dedicated pump that is plumbed directly to the waterfall and a separate pump for filters and water features.
