How high is the waterfall going to be?
The average is about 5′. Look at the box at head pressure, which is the ability for the pump to push the water at various heights. Water weighs 8 lbs/gallon. 2nd – How wide will the falls be? Let’s say 3′ wide, which is about average. We like to figure 100 gallons of water for every inch of waterfall width. That also figures 1/4″ thick of water going over the fall. This figures out to 3600 gallons/hour we need to go over the top, so we need to look for a pump that will flow 3600 gph at 5′ of head. Piece of cake! Next are the waterfalls……. Waterfalls – However you want to do them is all right. Just a few things to think about. 1st – Make sure you have a piece of liner behind the waterfall to catch the water that leaks from the waterfall. Also overlap it in the pond at least 1′. 2nd – Flat stone or field stone, field stone is usually less expensive. Flat stone you can use just about any flat stone, except sandstone.
