Relight pilot light on gas hot water heater - Newtown - URGENT today

$100

Newtown NSW 2042, Australia

24th Jul 2026

Pilot light on my gas hot water system went out after a gas supply shutoff (gas supply confirmed working - stove runs fine). Need it relit asap - before 9:30am or after 1pm please. It’s a standard outdoor gas storage tank with easy access. Should be a quick job for someone who’s done these before. If the pilot won’t stay lit it may need a new part - if you’re a licensed gasfitter, happy for you to quote on the spot. Bonus $10 if you bring surface spray and give the area around the unit a quick hit - there are some spiders in there.

Tristan was swift, punctual and thorough. Highly recommend!
