Installation Instructions

Thank you for choosing the Precision Meters, Brass Multi-jet Water Meter (Hot).

This device has undergone thorough testing and verification at Precision Meters’ SANAS Accredited Verification Laboratory, conducted by a certified Verification Officer, to ensure it meets SANS 1529-1:2019 Class B specifications. It is supplied in full working order.

As a precision instrument, the water meter features exacting tolerances between its moving parts and is designed exclusively for measuring potable water. Exposure to grit, sand, or other suspended solids can cause permanent damage to the meter. Such damage incurred during installation is not covered by the Precision Meters warranty.

To ensure proper installation, it is imperative that the installer maintains cleanliness throughout the process. Thoroughly flush the pipeline before installing the meter.

This water meter is approved by the NRCS for both vertical and horizontal installations. Its accuracy is unaffected by the angle of installation.

For installation, use the appropriate water meter tailpieces, which are available separately. Note: Standard female pipe adaptors must not be directly screwed onto the inlet/outlet of the water meter.

Please be aware that this meter is designed for hot water with a maximum operating temperature of 90 °C. Higher temperatures will irreparably damage the meter. Avoid using solder or applying heat near the meter during installation, as heat can travel through the pipe and damage the meter's internal components.

To prevent damage, do not install the meter where it may be exposed to shock, cavitation, water hammer, or surges caused by rapid valve operation. Ensure that the pipework aligns properly to avoid installation stresses on the meter. Additionally, the meter must be installed in a location protected from freezing, as frozen water can damage or burst the meter. Install at least one meter away from areas with potential freeze risks, such as a standpipe.

  1. Attach the separately supplied tailpieces to the water meter using the included sealing washers.
  2. Apply P.T.F.E. thread sealing tape to the male threads of the tailpiece linings.
  3. Screw appropriate female pipe adaptors onto the male end of the tailpiece lining. Note: Do not overtighten to prevent leaks; the thread sealing tape ensures the waterproof seal.
  4. Select a position where the meter will always remain full of water and avoid placing it at the discharge end of a pipe.
  5. Follow the flow direction arrow cast into the meter body, and ensure the meter is installed correctly. A built-in non-return valve will prevent flow if installed in reverse.
  6. Install a shutoff valve in the pipeline upstream of the meter for easier future maintenance.
  7. Fit the meter by connecting the pipe to the adaptors and tightening the fittings.
  8. When charging the lines, turn the water on gradually to expel air before fully opening the valve. Introducing high-velocity air can irreparably damage the meter. The pipeline must be entirely filled with water and all air expelled before the valve is fully opened to ensure correct operation.
