How to Fix / Troubleshooting
Safety: Turn off the main water supply and relieve pressure before altering plumbing.
- Verify flow direction: Check the arrows on the Tapworks valve body and ensure the inlet is connected to the mains supply and the outlet to the house.
- Inspect bypass loop: Confirm that the bypass valves are configured according to the Tapworks installation diagram.
- Test hardness at multiple points: Use a hardness test kit at different taps to identify which lines are softened and which are not.
- Correct plumbing: If lines are reversed or incorrectly teed, have a qualified plumber re‑pipe according to the Tapworks installation instructions.
