Designing with Aqua Gratis

Check the model options and water route, take a worksheet to your design review, or ask Cascade for current drawings and connection details.

Bath and shower water is filtered and stored. It can feed a dedicated cistern by gravity or supply an upstairs toilet via a pump.

Design resources.

Use the schematic at concept stage and the worksheet at a design review. For setting out on site, request the current drawing for your chosen model.

Product reference

Model schedule.

Use the family reference and the intended configuration in your enquiry. Optional Zypho shower heat recovery can be discussed for any of the three families.

01 Layout and access
  • Mark bath and shower outlets, toilet positions, floor levels and the proposed unit location.
  • Identify the WC mounting and soil pipe handing if the design uses an AG-100.
  • Ask for the model envelope, maintenance clearances and access for removing serviceable parts.
02 Building services
  • Review proposed collection and supply routes. Identify which cisterns may need a pumped supply.
  • Request model-specific pipe connections, electrical supply and control requirements.
  • If shower heat recovery is in scope, ask how the exchanger affects connections and access.
03 Commissioning and handover
  • Ask Cascade for the commissioning checks and operating information for the selected configuration.
  • Agree who will maintain the system, how they will reach it and who will handle fault reports.
  • Record the installed model, drawing revision and handover documents with the building records.
