Nick from The Clean Plumber came on Thursday afternoon to diagram and quote to fix a leaking upstairs hand basin which leaked onto the downstairs ceiling. Another plumber (not sure of his name as my wife was dealt with him) whom I met when I got home from work and he was finishing up the work. Both were very nice, helpful and very professional and they live up to company’s name. Highly recommended.

David from the Clean Plumber arrived on time.Extremely polite and helpful.Immediately located the problems and resolved both the leak and blocked Water Board main issue quickly and efficiently.Followed up with the Water Board and arranged for them to inspect their main line the same day.Could not be more satisfied.

Outstanding Service from Nick!Nick assisted with a plumbing issue involving my hot water system, and I couldn’t be more impressed. He was efficient, clearly communicated the problem, and promptly resolved it. His professionalism stood out throughout from diagnosing the issue to completing the job with care and attention. He even took the time to tidy up afterwards, which was greatly appreciated. Highly recommend Nick for anyone needing reliable and professional plumbing work.

Great service!A friendly Chinese gentleman (possibly named David) came to clean our plumbing. He carefully listened to all our concerns and did a fantastic job. He went the extra mile to make sure everything was clean and there were no blockages left. Super helpful and professional — really happy with the service! Super hero:)

I recently experienced a blocked toilet at home and contacted The Clean Plumber for assistance. David, the plumber who attended, delivered exceptional service. He was professional, efficient, and handled everything with great care. He thoroughly cleared the blockage, explained the cause to me, and ensured the area was left spotless—there was no mess at all.What I appreciated most was the honesty and transparency—there were no hidden fees, just straightforward, high-quality service. I’m extremely impressed with David’s work and would highly recommend The Clean Plumber to anyone in need of reliable and trustworthy plumbing services.

I used the Clean Plumber and they were honest in their assessment. A previous plumber installed our freestanding bathtub incorrectly and used the incorrect drain connection (for a sink instead of a tub) leading to unbearably slow drainage. I hired two other plumbers who couldn’t diagnose the problem correctly but the Clean Plumber came and identified the issue and re-installed the tub with correct parts. All along the process they were upfront as to how much it would cost to do the work based on issues found. They were pleasant to deal with and thoroughly explained how they were going to fix it. I would definitely use them again.

I recently had the pleasure of having Tanaka from The Clean Plumber handle a plumbing issue at my home, and I couldn’t be happier with the service. From start to finish, Tanaka was the epitome of professionalism. He arrived on time, which I greatly appreciated, and even wore shoe covers to ensure my home stayed spotless—such a thoughtful touch!Tanaka was incredibly polite and took the time to clearly explain the work that needed to be done, outlining all the options available with transparent and very reasonable pricing. This made it easy for me to make an informed decision without feeling pressured. His work was efficient, thorough, and left everything cleaner than when he arrived.Not only did he solve the plumbing issue flawlessly, but he was also genuinely pleasant to have around, making the whole experience stress-free. I will absolutely be using The Clean Plumber again, and I highly recommend Tanaka to anyone in need of a reliable, skilled, and courteous plumber.

My in-laws were after a reliable plumber but didn’t know anyone reputable. I did a google search for them and took a few quotes. Although The Clean Plumber wasn’t the cheapest, their quote was still very reasonable and they were by far the most professional to deal with. Happy with the job and glad we took the plunge. Workmanship 5 stars, Service 5 stars and reliability 5 stars. Job well done!!

FAQs

How long does a hot water unit typically last?

Most hot water systems last 8 to 12 years. Regular maintenance services such as anode checks and thermostat testing can extend the lifespan. Units that are serviced properly tend to run more efficiently and last longer.

What are current costs for supply & installation in Sydney?

Costs vary by size and type. Small electric hot water systems can start from around $900 fully installed, while larger gas hot water systems or instantaneous water heaters may range from $1,600 to $2,500. We always provide upfront pricing with no hidden extras.

Can you replace one system type with another?

Yes. You can switch from an electric hot water system to a gas hot water heater or move to an instantaneous system if you want energy efficiency and endless hot water. Our licensed hot water plumbers can handle the full installation process safely.

Is professional installation required?

Yes. All hot water system installations in Sydney must be done by licensed plumbers. Professional fitting keeps your water heater safe, compliant, and covered under warranty. DIY installs can create risks and void manufacturer guarantees.

How long does installation take?

Most hot water system installs take 2 to 4 hours. Same-day service is available if your system has failed and you need hot water quickly. Larger hot water tanks or switching from one system to the other may take longer, but we’ll confirm timing upfront.

What maintenance or service is needed?

Storage systems need servicing every 3 to 5 years to check anodes, flush sediment, and test thermostats. Gas and electric hot water systems both benefit from regular checks, while instantaneous water heaters should be inspected to maintain efficiency.

Why is my hot water system making strange sounds?

Sediment buildup inside the hot water tank is usually the reason behind the noise. Flushing and maintenance prevent this issue. If the sound persists, our team can inspect and repair the system to stop further damage.

Why is my hot water pressure low?

Low pressure may be caused by a valve issue, sediment in the tank, or if your hot water system is not aligned with your household needs. Our plumbers can test your supply, identify the cause, and restore proper flow.
