Gas Hot Water Repairs & Replacement in Marrickville NSW

Many people are relieved to learn that a single hot water plumber can do it all. We cover emergency hot water repairs, pilot and ignition faults, thermocouple and gas valve replacement, leaking cylinders and the renewal of TPR and tempering valves. Servicing, full replacements and new installs of storage or continuous flow units are also ours, including gas line and flue upgrades, and we work with natural gas and LPG so your fuel type never sends you looking elsewhere.

Storage cylinders hold water at 60 degrees Celsius, so a leak from a tank or TPR valve can release a large volume of hot water quickly, which is why leaking units sit alongside no hot water as emergency priorities for us. Shutting the cold water inlet at the top of the tank stops the leak at its source while a licensed gasfitter is on the way. We attend the same day wherever possible, including after hours.

Managing a rental on the other side of town from where you live is a common situation for landlords we work with. We cover the whole local area, so we can attend the property directly and report back to you.

Three things set the price of a hot water replacement more than anything else, the unit itself, the installation work, and the removal of the old system. A straight swap of the same type and size costs less than a change from storage to continuous flow, which can involve new gas line sizing and a new flue arrangement. Our written quote breaks each of these out so nothing is hidden inside a single lump sum.

Think of the thermocouple as a safety switch. Its job is to shut the gas off the moment it stops sensing heat, and as it ages it becomes too weak to keep the valve open even with a healthy flame in front of it. Replacement is straightforward for a licensed gasfitter and is the most common fix for a pilot that will not stay lit.

If your home insurer ever asks who connected your hot water system, the compliance certificate we hand over at the end of the job answers the question. It shows the work was completed by a licensed gasfitter, which is exactly what insurers want to see. Our team holds current licences and the business carries public liability insurance.

Fixing is the right choice far more often than people expect, particularly for units under about ten years old. Many no hot water callouts come down to a thermocouple, a blocked pilot jet, a faulty igniter or a tempering valve, all of which are routine to replace. Replacement only becomes the smarter path when the cylinder is failing, faults are recurring or the system is old and inefficient. We will always say so clearly rather than talk you into something you do not need.

Hot water is typically restored on the day of installation. A like-for-like replacement is the fastest path, and the compliance certificate is issued once gas pressure, water connections and temperature settings have been tested. We arrive with the unit and all fittings so the timeline is not stretched by parts runs.

A sacrificial anode on a storage cylinder is designed to corrode so the tank does not, and it is checked at every service because a spent anode shortens the life of the whole unit. Alongside the anode check the gasfitter cleans the burner and checks the flame, tests gas pressure at the regulator, tests the thermocouple, checks the flue and draught, operates the TPR valve and sets the tempering valve to 50 degrees Celsius. A sediment flush, a leak and carbon monoxide test and a written report round out the service.

Our workmanship guarantee means we stand behind every connection, joint and setting on the job. Should a leak, a flue issue or a setting problem show up afterwards, we return and correct it at no charge for the labour. The unit itself is separately backed by its manufacturer for the cylinder or heat exchanger and for its components.

Imagine the hot water fails the same week you had a new cooktop or barbecue line fitted. During that kind of work the gas isolation valve is often closed and not reopened, or the pilot blows out when the line is purged. Check the valve is open and, if the pilot needs relighting, follow the instructions on the unit before calling anyone.

On a rural property running LPG bottles, both system types are available and the choice turns on the bottle supply and the gas pressure at the unit. A continuous flow unit draws a lot of gas when it fires, so the regulator and bottle setup must be able to keep up, especially in cold weather. A storage cylinder draws more gently over a longer period, which can be kinder to a basic bottle installation. We check the whole gas setup before advising which way to go.
