Installation Instructions
Thank you for purchasing this high-quality Polymer Piston Domestic Water Meter.
The steps below will guide you through the proper installation process for your Polymer Piston Water Meter to ensure top performance and compliance with warranty conditions provided by The Water Company.
Step 1: Protecting the Meter
Firstly start by ensuring all plastic water meters are covered post installation.
This protects the meter from direct sunlight, which can be done using a housing or
meter box.
Step 2: Sizing
Secondly make sure the water meter is correctly sized according to the pipe size or the flow rate.
Step 3: Flushing Pipework
Before installation:
Flush all pipework to remove debris or sand, ensuring a clean pipeline.
Step 4: Meter Orientation
Install piston meters either horizontally or vertically.
Step 5: Avoiding Pressure
Ensure no pressure is applied to the meter during installation from misaligned pipes or excessive vibration, which can lead to failure.
Step 6: Fitting Installation
Avoid over-tightening fittings and excessive use of sealing materials like sealing tape, which can cause leaks.
Step 7: Thread Treatment
Only use thread tape or PTFE tape, ideally with tailpieces.
Step 8: Soldering Precautions
Avoid soldering near the meter, especially where brass fittings are involved, to prevent damage from heat.
Step 9: Water Type
Ensure the meter installed for cold water is not used in a hot water pipeline.
Step 10: Appropriate Usage
Use the meter only for clean potable water to avoid damage and inaccuracies.
Step 11: Handling Care
Handle the meter carefully as it is a precision measuring instrument.
Do not drop it or break the meter seal.
Step 12: Thread Fittings
Avoid using tapered thread fittings; Use of tailpieces is preferable.
Step 13: Additional Protection
Install a strainer before the water meter to protect it from sand or foreign debris.
