Recent Hot Water System Installation & Repair reviews in NSW

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.

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!

Plumber hot water

Marsden Park NSW, Australia

Chromagen M26/50 continuous flow hot water system needs flow rate recalibration. A Chromagen-appointed plumber has attended twice before and used a specialist recalibration device to fix the same recurring issue (system cutting out, intermittent hot water loss).

Fix wiring on hot water top and bottom element to solar timer switch.

$75

Hornsby Heights NSW 2077, Australia

30th May 2026

Had recently installed Analog Timer and Switch to connect hot water bottom element only on general rate + solar timer with a switch (up). It can also revert back to off peak (down switch) as before without timer. The problem is hot water only warm in the afternoon and cold again at night until the next afternoon. Guessing the problem is the top element not connected properly to continuous off peak as said in the manual (2nd pic), causing the bottom to never heats up. Task is to fix the existing wiring correctly on newly installed parts.

Bath tap leaking with hot water .temperature control faulty

$100

Mosman, New South Wales

30th May 2026

This morning, no shower had been taken. The bath tap was only turned on briefly. After that, the water coming from the bath tap was extremely hot and the tap continued to drip even after both bath taps were fully turned off. The wall tiles behind the bath also felt warm. A slight hissing noise was noticed near the hot water system. To stop the leaking, the hot water system was turned off. However, the bath tap continued to drip and the water coming from the drip was still warm. The mains water supply was then turned off, which reduced the dripping significantly and stopped the hissing noise, although a small amount of warm water was still dripping from the bath tap. After the hot water system was turned off, all other taps in the house only supplied cold water, however the bath tap continued to drip warm water. A valve on the hot water system was reportedly replaced around 3 weeks ago. Looking for a licensed plumber to inspect and diagnose the issue. It appears there may be a fault with the bath taps, the temperature control, and/or the hot water system or associated valves. Please inspect and provide advice and a repair quote if required.

Excellent service from Mark. He responded quickly and came to my property on the weekend to fix a leaking hot water tap. He was friendly, knowledgeable, and clearly very experienced. The repair was done efficiently and to a high standard. I highly recommend Mark and would happily use his services again.

Replacing old commercial instant hot water system

Glenfield NSW 2167, Australia

25th Apr 2026

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
