My Hot Water System – Signs You Need to Call a Plumber

June 8, 2020

You may think that the first sign of a hot water system that needs some attention is when it suddenly leaves you out in the cold during a bath or shower. However, it’s highly likely that it was sending you signals long before that happened.


Hot water systems work quietly in the background; reliable, and steadfast in their ability to provide us with hot water on demand.


In a lot of cases, it’s only when people feel the chill of a hot water system on the blink that they deign to think of it all. As a plumber, I can tell you that calling me before your hot water supply dries up may help prevent catastrophic failure and extend the life of your system.


Now that we are well into winter, you could also avoid a night or two of cold showers. Here are a few things about your hot water system that will tell you it’s time to get me on the phone.


Watch out for Leaks

A hot water system that is leaking water may be at the end of its life, but there’s also a good chance that a service will find and fix the source of the leak, which is a lot cheaper than a new system.


Weak water pressure

If your supply of hot water is running out much quicker than usual, then a service or replacement may be necessary. It’s better to do it now, rather than wait until you have no hot water at all.


Lower water temperatures than usual

If the water out of your tap is still warm, but never quite reaches hot, then it’s possible there is a problem with the tempering valve. A faulty cross connection may also be letting cold water mix in with the hot water.


Spikes in your energy use

If you think your hot water system isn’t working as well as it should, don’t delay calling a plumber to take a look. It takes a lot of energy to heat hundreds of litres of water every day. If your system is faulty in any way, then you may start noticing it on your power bill.

Drainage Upgrades in Warriewood

By Chris Smith • May 6, 2026
When Holly in Warriewood on Sydney’s Northern Beaches engaged Eze-Flow to address ongoing drainage issues around her property, the backyard had been experiencing constant water pooling and flooding in the backyard during heavy rain. Holly initially described the issue as a “very wet portion of the backyard”, suspecting additional aggy lines may be required. With new paving planned, there were concerns that without proper drainage, heavy rainfall would result in water flowing back toward the house. It was clear the existing stormwater system was not coping and required upgrading before any surface works could proceed. The works were completed in two stages across November 2025 and March 2026, delivering a complete drainage solution across the property.

Stormwater Drain Repair in Forestville

By Chris Smith • May 6, 2026
When a Primary School in Forestville began experiencing extensive stormwater blockages and localised flooding in May 2025, the issue was initially believed to be a simple blockage. Eze-Flow was called in to clear the stormwater system , however after attending site and beginning high-pressure water jetting to clear the multiple lines, it quickly became clear the problem was more complex. Grates were removed from multiple stormwater pits and heavy debris was manually cleared, including built-up soil, tree roots, and rubbish. One of the main pits was completely filled with compacted soil and roots, requiring excavation by hand before the outlet could be cleared. Using high-pressure jetting and CCTV drain inspections, we attempted to cleared both upstream and downstream. During this process, a significant amount of debris was removed, including food wrappers, chip packets, and multiple balls lodged throughout the pipeline. After approximately two hours of continuous jetting, two sections were identified as requiring excavation and repair. CCTV inspection confirmed a collapsed section of pipe, while another section was found to be obstructed by a foreign pipe that had been incorrectly installed into the stormwater line.
