The PVC Union Socket 20mm x 20mm is designed for joining equal-size compatible PVC pipe sections with a serviceable union connection in compatible professional PVC irrigation and water-distribution systems.

Correct pipe and adaptor selection helps maintain clean alignment, serviceability and reliable connections throughout fixed irrigation installations.

Key benefits

  • Product type: PVC Union Socket
  • Designed for joining equal-size compatible PVC pipe sections with a serviceable union connection
  • Dimensions retained from source specification
  • For compatible professional PVC irrigation systems

Joining PVC pipe with service access

A union socket joins compatible pipe while allowing the connection to be separated later for servicing. Install it where there is sufficient access to undo and remove components without placing strain on adjacent pipework.

Pipe preparation & solvent welding

Cut PVC pipe squarely, remove burrs and clean the mating surfaces. Dry-fit the layout where practical before applying compatible cleaner and adhesive.

Follow the adhesive manufacturer's current application and curing instructions. Do not assume one curing time is suitable for every pipe diameter, temperature or installation condition.

Supporting the installation

Support rigid pipework at suitable intervals and around valves, unions and heavy equipment. Avoid transferring mechanical strain into threaded adaptors or solvent-weld joints.

Commissioning & pressure checks

After the applicable curing period, commission the system gradually and inspect joints for leakage. Operating pressure must remain within the requirements of every component in the complete system, not simply the pipe itself.

Maintenance

Inspect accessible pipe and fittings periodically for leakage, movement, impact damage or cracking. Isolate the system before servicing and repair faults using compatible components and proper joint preparation.

PVC Union Socket 20mm x 20mm FAQs

What is this product used for?

Joining equal-size compatible pvc pipe sections with a serviceable union connection.

How do I check the correct size?

Match every stated pipe diameter, thread and connection type to the intended system.

Should PVC pipe be cut squarely?

Yes. Square, deburred cuts help fittings seat correctly and support reliable solvent-weld preparation.

Can I force an adaptor onto a different size?

No. Use components specifically compatible with the stated dimensions and thread type.

Should rigid PVC pipe be supported?

Yes. Support runs so joints and equipment connections are not carrying avoidable mechanical loads.

When can a solvent-weld system be pressurised?

Follow the adhesive manufacturer's current curing and commissioning instructions.

Does pipe diameter affect irrigation performance?

Yes. Diameter, run length and flow affect water velocity and pressure loss through the system.

What should I do if a joint leaks?

Safely isolate the system and repair the joint correctly rather than relying on temporary external sealing.
