Our Gas Geyser & Water Heater Diagnostic Process
Step 1: Initial Inspection & Ignition Testing
We start by visually inspecting your gas geyser or water heater and testing the ignition system. For battery-operated units, we check battery voltage and spark electrode function. For 220V units, we verify power supply, PC board status, and ignition circuit.
- Visual unit inspection
- Battery voltage testing (if applicable)
- Spark electrode condition check
- Ignition sequence verification
- 220V power supply check (if applicable)
Step 2: Pressure Testing & Flow Analysis
We perform comprehensive pressure testing to ensure your gas geyser or water heater is operating within safe parameters. Water flow rates and gas pressure are checked to verify proper operation and heating performance.
- Gas pressure measurement
- Water inlet pressure check
- Flow rate analysis
- Safety valve verification
Step 3: Full System Testing & Bench Diagnostics
Once on-site testing is complete, we perform comprehensive system diagnostics on your gas geyser or water heater to ensure all components function correctly. This includes temperature stability checks and full water heating performance validation.
- Full water flow heating test
- Temperature stability check
- Control valve testing
- Electronic component verification (220V units)

What's the difference between battery and 220V gas geysers and water heaters?
Battery-operated gas geysers use AA or D batteries for the ignition spark and require no electricity. 220V water heaters use mains power for the PC board, fan, and ignition - they're more complex but more reliable. We service both types of gas geysers and water heaters.
How do I know if my gas geyser or water heater battery needs replacing?
If you hear clicking sounds when turning on a tap but the unit won't ignite, or the spark is very weak, the battery is likely dead. Try replacing the batteries first (usually AA or D cells) before calling for service. Most gas geyser units take 2-4 batteries.
Why is my gas water heater or geyser not igniting?
Several reasons could cause ignition failure in your water heater or gas geyser: weak/dead battery (if battery-operated), clogged spark electrode, water not triggering the flow sensor, insufficient gas pressure, or faulty ignition circuit. Check battery first if applicable, then call for professional diagnostics on your geyser.
How can I improve weak hot water pressure in my gas geyser?
First, check if the inlet water filter is clogged in your water heater or gas geyser. Many units have a small filter screen at the water inlet that can be cleaned. If that doesn't help, the issue may be low inlet pressure from your main supply, low gas pressure, or a faulty flow sensor - these require professional testing of your geyser.
What should I do if I smell gas from my water heater or geyser?
Leave the area immediately and turn off the gas at the meter if you can do so safely. Do NOT use any electrical switches or create sparks. Call us or emergency services right away. A gas smell indicates a potential leak in your gas geyser or water heater and is a serious safety issue.
How long does a typical gas geyser or water heater repair take?
Most repairs take between 30 minutes to 2 hours depending on the issue with your water heater or geyser. Simple diagnostics and battery replacements are quicker. Complex repairs requiring component replacement or testing may take longer. We give you a time estimate after diagnosis on your gas geyser.
Do you offer same-day service for gas geyser and water heater repairs?
Yes, we offer same-day service on most gas geyser and water heater issues. During business hours, we often have availability for emergency calls. Contact us to check availability for your location and the type of service you need for your geyser or water heater.
Can you repair all gas geyser and water heater brands?
Yes, we service and repair all brands of gas geysers and gas instant water heaters. We carry parts for most common geyser and water heater models and can source others quickly if needed.
