Water & Gas Test Gauges

About Water & Gas Test Gauges

Water and gas test gauges are essential diagnostic instruments used to measure pressure in water and gas systems, ensuring installations meet safety standards and operate efficiently. MyToolShed.co.uk supplies professional-grade test gauges designed for accurate pressure testing, leak detection, and system commissioning across domestic and commercial properties. These precision instruments are indispensable for verifying system integrity before final connection and throughout routine maintenance schedules.

Available in two specialist categories—gas test gauges and water test gauges—these tools are engineered to withstand the demanding conditions of on-site testing whilst delivering reliable, repeatable readings. Whether you're pressure testing new installations, diagnosing faults, or certifying gas-safe compliance, MyToolShed stocks gauges calibrated to meet UK regulations and industry best practices for plumbing and gas fitting professionals.

Applications

• Gas Safe registered engineers – testing gas pipework for leaks and pressure drops during installation and servicing
• Plumbers and heating engineers – commissioning central heating systems and testing water supply pressures
• Maintenance contractors – routine inspection and fault-finding on commercial gas and water systems
• Building services engineers – verifying system pressures meet design specifications on new builds
• Landlords and property managers – ensuring rental properties comply with gas safety regulations
• Water utility companies – mains pressure testing and supply verification
• Domestic installers – certifying domestic boiler installations and water systems

Choosing The Right Water & Gas Test Gauges

Select gauges appropriate to your testing requirements and the systems you work with regularly. Gas test gauges typically measure in millibars (mbar) and must comply with Gas Safe standards, whilst water test gauges generally measure in bar or PSI for higher pressure ranges. Consider whether you need analogue dial gauges for traditional ease of reading or digital models offering enhanced precision and data logging capabilities.

Pressure range is critical—ensure your gauge covers both the working pressure and test pressure required for your applications. Build quality matters significantly; look for robust casings that protect against drops and site conditions, with clear, well-marked dials for quick reading. Many professional gauges available at MyToolShed.co.uk feature protective rubber boots and calibration certificates for compliance documentation.

Check compatibility with your existing test equipment, including hose connections and adaptor fittings. For gas work, gauges with fine resolution around the 20-21mbar working pressure range provide the accuracy needed for drop testing, whilst water testing may require gauges reading up to 10 bar or higher depending on system type.

Safety Information

Gas testing must only be performed by Gas Safe registered engineers in accordance with current regulations. Always use correctly calibrated equipment and ensure test gauges are within their certification period. Never exceed the maximum pressure rating of any gauge, as this may damage the instrument and compromise readings. When testing gas systems, follow purging and tightness testing procedures as specified in industry standards, and never use water test equipment on gas installations or vice versa.

Frequently Asked Questions

How often should test gauges be calibrated?

Professional test gauges should be calibrated annually to maintain accuracy and compliance with Gas Safe and industry standards. Keep calibration certificates with your equipment for inspection purposes.

What's the difference between gas and water test gauges?

Gas test gauges measure lower pressures (typically 0-100mbar) with high precision for leak detection, whilst water test gauges handle higher pressures (often 0-10 bar or more) for hydraulic testing. They're not interchangeable due to different pressure ranges and accuracy requirements.

Can I use digital gauges instead of analogue?

Yes, digital gauges are acceptable and often preferred for their precision and data recording features. Ensure any digital gauge meets the relevant British Standards and is suitable for your specific testing requirements.
