AQUA Rainwater Systems Compatibility and Flow Guide
Quick guide to AQUA rainwater system compatibility and flow capacity specifications. Check manufacturer compatibility and flow rates for 112mm and 150mm gutter systems.
Table of contents
Quick guide from the manual
This document provides technical specifications for AQUA rainwater systems. It serves as a reference for determining compatibility with existing gutter systems from various manufacturers and provides flow capacity data to assist in system planning and installation.
Compatibility Chart
The compatibility chart outlines which AQUA gutter systems (112mm Half Round, Square Line, Deep Flow, Krown Ogee, and 150mm Kommercial) are compatible with products from other manufacturers. Always verify the manufacturer of your existing system against this chart before attempting to connect or integrate components.
Gutter Flow Capacity
The document provides flow capacity data measured in Litres/Sec. These figures are categorized by the position of the outlet and the gradient of the gutter run:
- Outlet at the centre of the gutter run: Provides higher flow capacity compared to end-outlet configurations.
- Outlet at the end of the gutter: Provides lower flow capacity.
- Gutter Level vs. 1:350 Gradient: Data is provided for both level installations and those with a 1:350 gradient, which improves water flow.
Important Warnings
The information provided in this document is for guidance only. The manufacturer does not recommend mixing systems from different brands, as all manufacturers have slightly different tolerances which may lead to leaks or improper fitment.
Practical help
Common problems
Mixing systems from different manufacturers
Do not mix systems. Different manufacturers have slightly different tolerances, which can lead to installation issues.
Before use
- Identify the manufacturer of the existing gutter system.
- Consult the compatibility chart to ensure the AQUA system is compatible.
- Determine the required flow capacity based on the planned outlet position (center or end).
- Check the installation gradient (Level or 1:350) to ensure it meets flow requirements.
Specs in practice
- 1:350 Gradient
- A slope ratio used to calculate water flow capacity; a gradient allows for higher flow rates compared to a level installation.
- Gutter Level
- Refers to the flow capacity when the gutter is installed horizontally without a slope.
- Outlet Position
- The location of the downpipe outlet (center or end of the gutter run) significantly affects the total flow capacity of the system.
Model compatibility
- The compatibility chart is for guidance only.
- Mixing systems is not recommended due to tolerance differences.
