Electricity
Electrical Costs
POWER = WATTS
Current (Amps) x Voltage (120v or 230v)
FORMULA: WATTS = CURRENT X VOLTAGE
CURRENT = AMPS
Power (Watts) / Voltage (120v or 230v)
FORMULA: AMPS = POWER / VOLTAGE
Electricity Costs
Amps x Voltage / 1000 x KWH Cost x 24hrs x 30days

Retaining Wall Waterfall
How it Works...
A Retaining Wall Waterfall works much like a pond-less waterfall.
The Formal Falls molded Basin is placed on a suitable base with the pump protected inside the basin. Wall block or other suitable material is stacked all around the molded basin. The Formal Falls spillway rests inside the wall block and is covered. The pump inside the basin pumps the water via tubing to the Formal Falls where the water returns via a waterfall into the basin. An LED light strip, located inside the Formal Falls unit, illuminates the waterfall for a spectacular night display.
Formal Falls Basin
How it Works...
Formal Falls Basins can be sunk in-ground or used above grade with NO Winterizing needed. In the spring simply drain and add fresh water. The basin come equipped with dual pump access (left or right side) through a stainless steel access panel located just under the splash mat. Additionally, if you are looking to install our Elite AutoFill Valve to maintain the water level or to reduce manual filling, a pre-installed spinweld located on both the left and right makes installation fast and easy.
