Possible Causes

Inlet and outlet reversed, Bypass plumbed incorrectly, House fixtures still connected to raw water line, AquaHouse softener installed on hot line by mistake

How to Fix / Troubleshooting

Safety first: Shut off main water and relieve pressure before altering plumbing. If unsure, hire a licensed plumber.

Step-by-step:

  • 1. Verify inlet/outlet: Check the arrows on the AquaHouse control valve body and ensure the inlet is connected to the supply and outlet to the house.
  • 2. Inspect bypass piping: Confirm that the bypass is correctly installed and not allowing raw water to mix with softened water.
  • 3. Trace lines: Follow the piping to ensure all desired fixtures are supplied from the softener outlet.
  • 4. Correct mis-plumbing: Reconfigure piping as needed to match AquaHouse installation diagrams.
