Plumbers Bellows

About Plumbers Bellows

Plumbers bellows are essential hand tools used for testing drainage systems, pipework, and sanitary installations. These manual air pumps generate controlled air pressure to detect leaks, blockages, and faulty connections in drainage systems before they're put into service. MyToolShed.co.uk stocks professional-grade plumbers bellows from trusted brands including Bailey and Monument, designed to meet the demanding requirements of professional plumbers and heating engineers.

A typical plumbers bellows set includes the hand bellows unit itself, along with compatible rubber tubing and connection pieces such as Y-pieces that allow testing of different pipe configurations. These drain testing tools are built with durable rubber construction and reliable valve mechanisms to maintain consistent pressure during testing procedures, making them indispensable for compliance testing and quality assurance work.

Applications

Plumbers bellows are primarily used by:

• Plumbers and heating engineers – testing new drainage installations and sanitary pipework
• Building contractors – verifying drainage systems meet building regulations before handover
• Property maintenance professionals – diagnosing drainage problems and testing repairs
• Construction site managers – ensuring compliance with water regulations and drainage standards
• DIY enthusiasts – testing home plumbing projects and bathroom installations

Common applications include air testing soil stacks, waste pipes, vent systems, and underground drainage connections to identify leaks before commissioning.

Choosing The Right Plumbers Bellows

When selecting plumbers bellows from MyToolShed.co.uk, consider these key factors:

• Capacity and pressure range – Ensure the bellows can generate sufficient pressure for the pipe diameter and system type you're testing
• Build quality – Look for robust rubber construction with reinforced seams that won't perish or leak during regular use
• Valve reliability – A quality non-return valve is essential for maintaining steady pressure during extended tests
• Compatible accessories – Check that appropriate tubing, adaptors, and Y-pieces are available for your specific testing requirements
• Brand reputation – Established manufacturers like Bailey and Monument offer proven reliability for professional tradespeople

Frequently Asked Questions

What pressure should I test drainage pipes at?

Standard air testing for domestic drainage typically requires maintaining 100mm water gauge (approximately 10mbar) for three minutes. Always consult current building regulations and manufacturer specifications for your specific installation.

How do I maintain my plumbers bellows?

After use, release all pressure and store in a cool, dry place away from direct sunlight. Check rubber components regularly for perishing or cracks, and ensure valves remain clean and unobstructed. Replace tubing connections if they show signs of deterioration.

Can plumbers bellows be used for water testing?

No, plumbers bellows are designed exclusively for air testing drainage systems. Water testing requires different equipment and procedures. Air testing is often preferred as it's cleaner, easier to perform, and quickly identifies leak locations.
