Looking to improve the energy efficiency of your pool?

Waterco’s 50 mm PVC Sweep Elbow features a long radius that results in efficient water flow, a solution to improving a pool’s hydraulic efficiency, particularly when using energy-efficient pumps

Research comparing the 50 mm PVC Sweep Elbow to traditional 90° elbows shows a marked difference in water flow and head loss.

The chart below illustrates the difference in pressure drop between a 50mm Elbow and a 50mm sweep elbow at different flow rates.

Sweep Elbow comparison chart

If a pool filtration plumbing system used 10 x 50 mm PVC sweep elbows in place of 90° elbows, this would reduce the overall system head loss by 1.5 m and improve the pool’s hydraulic efficiency.

Additionally, by improving the hydraulic efficiency, it enables a multispeed or variable speed pump to operate at a lower speed without sacrificing flow rate through the pool’s filtration circuit or reducing the pool’s turnover rate.

  • Sweep elbows increase your flow rate
  • Improves water hydraulics, particularly when using energy-efficient pumps
  • Improves backwashing ability
  • Decreases stress on equipment
  • For the ultimate in efficiency and good looks you cannot go past a sweep elbow.
