Disconnect and remove 2 solar hot water heaters

$250

Neutral Bay NSW 2089, Australia

27th Jul 2026

These solar hot water heaters (not powered, just has water running through it) are rusty and leaking, I need to decommission and remove. Each heater panel is about 2x1m. I am fit and able to help lift, but I can’t do it alone; ideally I need a plumber who can disconnect / block off the pipes from the internal HSW. All i really need is for someone to disconnect it at the source, and then help me get it off the roof. I’ll do the rest. Flat room, easy access.

Brilliant work, helped me solve a lot of problems as we went. Very professional. Thank you ☺️

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!

Need a plumber to inspect an issue with hot water not travelling to bathroom taps. Only working in kitchen. Added a picture of the current water boiler (under the kitchen bend) which is quite old. May need a new one installed as I believe the root issue is the water boiler isn’t able to send hot water to the other side of the house. It’s a red brick building.

Hot water heater Problem

$200

West Ryde NSW 2114, Australia

6th Jul 2026

I require a licenced plumber to diagnose and fix issues with the hot water in the house. Even though the heater is set at the highest setting of 7, the water in the taps in the house is luke warm (around 30 degrees). Looks like the external valve need to be adjusted/replaced. The heater is a Dux Prodigy-storage tank gas heater (135 litres) that is about 3 years old - bought from and installed by Bunnings / Dux. Please quote for the labour costs to fix the issue. We will pay for materials (e.g. replacement valves) on actuals of the receipts provided. Dates available - Wednesday, Friday, Monday
