Quick, efficient and no bs
Take old hot water tank
$75
AIDAN IS THE BEST PLUMBER I HAVE EVER HAD! We recently had another plumber from airtasker out who said they cleaned and fixed our gutter problem but they never did. Aidan took photos before and after to show us the job was completed and found the issue for a leak we had. He also supplied and installed a hot water unit for us and was so reasonably priced unlike other plumbers we recieved quotes from prior. While he was completing the jobs around our place he also quoted us for backyard drainage and again his prices are so reasonably priced we honestly feel like we have been ripped of prior to finding aidan! We will definitely be using him as our family plumber from now on! Thank you again aidan such a polite and honest plumber!

Abbas fixed my shower head and sink. He was on time, polite and very professional. I would definitely call him again for all my plumbing needs.
Hot water not coming out of shower head
$100
The job was completed successfully but with a delay. Being without hot water in winter made this an urgent task. It would have been nice to have had the task completed on Tuesday (the day I posted the job) but since it was not confirmed until the middle of the day it would have been unreasonable to expect it done then. The fact that it was not done until Friday because of other work was, however, quite inconvenient and in my opinion this was unreasonable. It was disappointing that the job was accepted if it could not be done within a time frame appropriate for an urgent job. Replacing a thermostat is a fairly quick (around 30 minutes) and routine job for a plumber. If had known it would take that long I would have pursued other alternatives.

Voyager Point NSW, Australia

My Rinnai Infinity 26 gas hot water system stopped working last night, and we currently have no hot water. I believe the unit was installed more than 20 years ago, so it may need major repairs or full replacement. I am looking for a licensed and experienced gas hot water technician to inspect the system and provide a quotation as soon as possible, preferably with the issue resolved by Monday. If the system cannot be repaired economically, please provide replacement options including: Recommended brand and model Supply and installation cost Warranty details Estimated timeframe for installation The work can be completed on Saturday or Sunday if needed, although I would prefer standard rates without additional weekend charges where possible. Please contact me with your availability and quote details. Thank you.

Hi, the property currently has no hot water. The electric hot water system breaker is tripping and sitting in the middle position at the switchboard, indicating a fault with the hot water system. Could you please attend and repair the issue tomorrow. Thanks
Fantastic service from start to finish. They came out within a day and replaced our hot water tank quickly and professionally.

我家里有一台用了约17年的旧燃气热水器,已无法正常工作,需要更换。 这台旧机器比较特殊,是一台商业/工业级的即热式(瞬时)燃气热水器。 标签显示其燃气入口压力为 50 mbar (Pinlet max 50 mbar),由 SIT 在墨西哥组装。 目前在设备上能找到的标签照片已附上。 “预算 $200 是上门检测费和出方案的费用。换热水器的全包价请在报价时另外报。” 需要您完成的四项工作: 上门检测:请持牌燃气工携带专业设备,实测我家现有的燃气管道压力 (kPa/mbar) 和燃气类型 (Natural Gas 或 LPG)。 评估管径:我家的燃气管道较细 (目测约10mm),请评估是否需要更换管道以满足新家用热水器的供气需求。 提供解决方案:根据检测结果,请告知: 目前的燃气压力能否直接安装普通家用燃气热水器? 如果需要降压,安装一个调压器的费用是多少? 应该选哪种合适的家用热水器 (比如Dux 135L储水式或Rheem即热式),以及对应的全包报价。 提供总包报价:包含拆旧 + 运走旧机 + 提供并安装新机 + 必要的燃气调压器/管道改造 + 调试的固定包干价。 请带着您的 NSW Gasfitting Licence 来报价。任务发布地点在 Glenfield 2167,我可以拍照提供更多旧机细节。
Tehsein was professional and an excellent communicator during the heater inspection. He has great attention to detail and went beyond his scope of work by pointing out that our gas meter had a leak. Much appreciated!

Fix shower taps - getting either hot water or cold water
$10
Quakers Hill NSW 2763, Australia
19th Apr 2026
We are getting either hot water or cold water in our shower taps. For eg. When turning the cold tap, instead of progressively getting increasing water pressure, nothing happens and then at some stage, you get a strong stream of cold water. There is likely a problem with the pressure valve. This needs to be fixed in two showers.
Great bloke to work with, punctual, great communication, great piece, very efficient. Would definitely book again
