Why Choose a SQE?

✔ Consistent Shower Pressure
✔ Better Performance with Multiple Outlets
✔ Reduced Power Consumption
✔ Less Pump Cycling
✔ Longer Pump Life
✔ Premium User Comfort
For customers wanting the closest thing to a SCALA2 supplied directly from a bore, the SQE is often considered the ultimate solution.
