Purchasing a High Efficiency Dual Pass HEDP Softening System for your home?

On very hard water supplies (> 75 Gpg), it’s common for hard water to “slip” through the system to your taps and appliances.

The High-Efficiency Dual Pass (HEDP) Water Softener uses a two tank system to prevent this problem.

The first tank acts as the workhorse by significantly reducing the water hardness. The second tank acts as a ‘polisher’ and prevents slippage as the overpowering high hardness condition has been significantly reduced.

This also increases the contact time with the softening resin meaning more consistent, softer water. Salt efficiency is even more important on high hardness situations.

The Hydrotech HEDP offers salt-efficient Up Flow regeneration with precision brining for ultimate salt savings.
