Heads up: Water Quality is in early access. Expect changes and new features as we continue to improve the module.

Overview

Water quality parameters are the individual values you want to measure (e.g. Free Chlorine, pH, Total Dissolved Solids). Each parameter must have a minimum and maximum value defined in the ruleset. These thresholds ensure checks are validated consistently across your organization.


How to configure measurement parameters

Open your ruleset

  1. Go to Configuration → Checklists → Water Quality Ruleset.

  2. Select the ruleset you want to configure.


Add or edit a parameter

  1. Open the subrule (e.g. “Deep Water Pools”).

  2. Locate the parameter you want to configure (e.g. Free Chlorine, pH, Calcium Hardness).

  3. Enter a minimum value and a maximum value.

  4. Click Save.


Required values

All parameters in a ruleset are required to have a value. However, you can control in the Water Quality Question configuration when adding the Water Quality question to a checklist whether staff are required to check that parameter in the field.

Tip: Use this flexibility to avoid unnecessary checks — for example, enable pH and chlorine for pools, but skip bromine unless it applies to your site.


Available parameters to configure

  • Free Chlorine – ensures disinfectant levels are effective.

  • Combined Chlorine – monitors buildup of chloramines.

  • Total Chlorine – total disinfectant measurement.

  • pH – water acidity or alkalinity.

  • Alkalinity – buffer to stabilize pH.

  • Calcium Hardness – prevents corrosion or scaling.

  • Cyanuric Acid – stabilizer for chlorine.

  • Total Dissolved Solids (TDS) – overall water quality balance.

  • Salt – for saltwater pools.

  • Bromine – alternative disinfectant.

  • Phosphates – nutrient monitoring to prevent algae.

  • ORP (Oxidation Reduction Potential) – real-time measure of disinfection capacity.


Best practices

  • Set values based on local health regulations and industry standards.

  • Use different subrules if pools, spas, or water features require different thresholds.

  • Review thresholds regularly to ensure they meet current operational standards.


Frequently Asked Questions

Q: Can I leave a parameter blank?
A: No. All parameters must have a minimum and maximum value, even if they are not required in the field.

Q: Can I change parameter values after staff have started using them?
A: Yes, but changes only apply to future checks. Historical results will not be updated.

Q: What happens if staff enter a value outside the min/max range?
A: They will see a validation warning and be prompted to address the issue before completing the checklist.
