Top Instant Gas Hot Water System Problems (and How to Fix Them)
1. No Hot Water at All
Nothing’s worse than turning on the tap and getting icy water. This could be due to:
- Pilot light issues (especially in LPG systems)
- No gas supply
- Faulty ignition system
✅ Quick Fix: Check if your pilot light is on and ensure the gas valve is open. Still no luck? Book an urgent repair with SEQ Pipeworks.
2. Inconsistent Water Temperature
Water that suddenly turns cold mid-shower? That’s a common complaint.
Causes include:
- Mineral build-up in the heat exchanger
- Malfunctioning thermostat
- Fluctuating water pressure
✅ Solution: Regular descaling, pressure checks, and thermostat replacement. SEQ Pipeworks can handle it all—book your system service today!
3. Low Water Pressure
If your taps are trickling, it could mean:
- Blocked inlet filters
- Pipe corrosion or buildup
- Partially closed valves
✅ What to do: Open all valves fully and clean out filters. For persistent pressure issues, our Gold Coast plumbers are just a call away.
