Over time, sediment and ‘hard water’ take their toll on pipes and hot water cylinders. Build-up can cause malfunctions and failure of elements, valves and circulation. Normal wear & tear can eventually cause failures too. Only with regular servicing can you prevent major issues.
For uninterrupted supply of hot water, it is recommended to have your system checked, flushed and maintained by a Master Plumber every few years. Book a complete service of your home’s hot water system with JT Plumbing today.

It’s very important that your hot water cylinder is set at the right temperature! A little too hot and your hot water can cause serious burns within seconds. A little too cold and you risk growing dangerous Legionella bacteria in your hot water cylinder. Read more on our post about the subject.
It depends on how your hot water cylinder is behaving. You can often get an idea of what the issue might be from a few simple signs. We’ve written a post about diagnosing the loss of hot water, and you can read it here.
A modern hot water cylinder with insulated pipes can be far more efficient and less costly to run than an older unit. The most efficient kind of hot water heater is a hot water heat pump, which produces more heat energy than the electricity that it uses! There are more simple ways to save money on hot water, and you can read about them here.
Hot water technology has advanced a lot over the past few decades. Unfortunately, if your shower pressure has always been lacking then it’s likely that your hot water cylinder uses old technology. There’s definitely a solution to the problem though: an upgrade! Be sure to read our post about low pressure vs high pressure hot water cylinders.

Amazing service, highly recommend for any projects you have!!Posted on Sophie GemmellFebruary 18, 2026.Trustindex verifies that the original source of the review is Google. Many thanks to the Team at JT Plumbing for the excellent service I recieved recently. I was particularly impressed with Plumber Phil who tended to a Kitchen Faucet issue in my home. He was so professional and explained clearly what was causing the issue, and how he remediated the problem. I also really appreciated his cheerful nature too. Just an additional note, I really appreciated how Phil promptly tended to my additional requests. Thank you so much Phil.Posted on Lynley DrainFebruary 16, 2026.Trustindex verifies that the original source of the review is Google. Not all companies have such a great emphasis on customer service. They are excellent to deal with from the person on the phone, through to the plumber that calls, right up to the manager. I only have the highest of praise for them in terms of customer service, reliability and good value for money. Not often you get an invoice which is less than you think! If you want really nice people to deal with, then I can recommend these guys.Posted on Cameron Speirs-HuttonJanuary 21, 2026.Trustindex verifies that the original source of the review is Google. Shane came on super short notice and was awesome. Super quick, crossed every option off and found our leak, fixed, and it was all sorted. Cheers guys!Posted on Morgan SmithDecember 23, 2025.Trustindex verifies that the original source of the review is Google. Honest, knowledgeable and friendly people. They show up on time, do a great job and charge a fair price. Had several jobs done by them over a period and have been happy each and every time. Highly recommended.Posted on Matt KennedyDecember 5, 2025.Trustindex verifies that the original source of the review is Google. Had a fantastic experience with JT Plumbing Drainage & Gas. They installed a new cistern for me and did an absolutely outstanding job. Their customer service was excellent from the moment I called right through to the job being finished. They were professional, friendly, able to come on short notice, and completed the work quickly. The price was very reasonable, and they left everything spotless — even disposing of the old cistern and all the rubbish for me. Really impressed with the whole experience. JT Plumbing will be my go-to plumber from now on. Highly recommend!Posted on Nita TakiariNovember 30, 2025.Trustindex verifies that the original source of the review is Google.

We have had J&T Plumbing with Grant do repairs at our home over the last couple of years. Recent time, we had a WasteMaster leak. Plumber Shane called in, and very quickly knew what the problem was. Went away and quickly returned with a new WasteMaster. Took a very short time to replace a check there was no leaks.He is super tidy and so polite. We Highly recommend J&T Plumbing and staff. To all.
