Ben,

Waterfalls are a whole different area. It is not necessarily the height,
but the amount of water going over the cascade. Lift of a pump is important
for this will tell you what gallonage you pump is going to put over the
falls.

Here is a pretty good rule of thumb for water falls. For every 100gph at
the discharge of the waterfall, the pump will create a flow 1/2 inch deep
and 1 inch wide. So as an example, a 600 gph discharge at the top of falls
will have a flow producing a stream 6 inches wide and 1/2 inch deep. To
expand this if you pump at the top of the falls was discharging 1,200gph and
the stream was only 6 inches wide the depth of water cascading over the
falls would be an inch deep.

Waterfall pumps are usually inefficient and require more power to run.

I am in the process of building a pond about 1500 gallons.

I currently have two submersible pumps. 1 535 gph beckett, 1 200 gph
(not sure)

My wife wants a waterfall probably about 2 ft high..


I am trying to understand the Pluses and Minuses of a normal pond pump
vs a waterfall pump...

I know one thing to keep in mind is the max lift..

But when I compare prices the Waterfall pumps seem to be cheaper..

EX..

Pond pump 500 GPH $89.99 and a waterfall pump 2000 GPH $119.99

So what I am wondering is... If a 2000 GPH waterfall pump is only
$30 more.. Than why not go with that..
