Common Hot Water Problems We Fix

No Hot Water or Fluctuating Temperatures: A system that delivers no hot water or struggles to maintain consistent temperature often indicates a failing element, thermostat issue, or blocked line.

Leaks from Tanks, Pipes, or Valves: Leaks can lead to water damage and wasted energy. We locate the source—whether it’s the tank, pipework, or pressure valve—and provide lasting repairs.

Pilot Light and Ignition Faults: Gas systems may fail to ignite, or the pilot light may keep going out. Our licensed plumbers test the components and restore safe operation.

Strange Noises from the Unit: Banging, hissing, or rumbling noises are usually caused by sediment build-up or failing parts inside the tank. We flush, repair, or replace the affected components.

Discoloured or Smelly Water: Rusty, brown, or foul-smelling water signals corrosion inside the tank or bacterial growth. We assess the extent of the damage and recommend repair or replacement.

Low Water Pressure: Weak flow or pressure problems may be caused by faulty valves, sediment blockages, or issues in the supply line. We restore normal pressure with targeted repairs.

Hot Water Heater Installation




If your water heater is with a tank, you should replace it after its expiry date. However, this condition applies when you have regularly and adequately maintained the heater; if not, you should replace it when you start getting some warning signs.

These warning signs include high heating bills, low volume of warm water, and the appearance of reddish color inside the heater. It indicates that the period of the water heater has finished.

Other warning signs include noisy pitch and leakage in the heater. If you receive one of these warning signs, call a plumber to replace it.

On the other hand, an Instantaneous water heater has a longer lifespan than heaters with a tank. There are no specific warning signs for it. However, some indications can tell you that the time has come to replace your heater.

Warning signs like irregular water temperature, deteriorated water quality, and leakage are enough to determine that your heater is no longer in its usable position.

If you receive one of these signs, you should replace your heater as soon as possible with the consultation of the plumber to prevent any mishap.





The lifespan of a water heater depends on its type. If your water heater is with a tank, it can last about 8 to 10 years with regular services. The lifespan of Instantaneous water heaters is about 15 to 20 years if serviced regularly.

If it is a gas-type heater, it can last about ten years. Similarly, an electric gas heater has a larger expiry time frame than a gas type. It can last for almost 15 years. These are some general lifespans of heaters taken as an average.

Some factors affect the lifespan of water heaters. The factors include whether the heater is with a tank or Instantaneous, the quality of water, the location of the heater, and daily usage.

The lifespan will be shorter if you use it more than once daily. Also, hard water in the tank can lessen your heater’s lifespan by about two years.

Moreover, the location of your heater is a significant factor in its lifespan. It would affect your heater badly if it is located in the basement, where it takes more time to heat the water.





It is crucial to consider some factors to select a good water heater for your home. These factors can tell you which water heater is best for your home. The factors include cost, fuel type, home space, and size.

The heater can affect your heating bill positively or negatively, depending on the fuel type. For example, if it is electrical, the bill charges will be higher than the gas type. Similarly, tank water heaters consume higher energy than Instantaneous ones.

You should focus on the size of the heater and compare it with the size of your home before selecting it. If your house is small, consider choosing an electrical water heater, while the heat pump or hybrid water heater is the best for a large home.

The cost of a water heater varies according to its type. If your budget is low, choose an Instantaneous water heater. In case of a high budget, you should buy a solar or hybrid type heater.

Before buying a heater, know its size. You should select a heater tank depending on the people in your house. For example, a 50-litre tank is enough for 2 or 3 occupants. Similarly, a 315-litres tank is adequate for 5 to 6 occupants.





The time depends on whether you want to install or replace a new water heater. If you install a new heater in your bathroom, it will take less time than replacing it. A licensed and certified plumber can install a new one in just 1 hour with a safe process.

If you want to replace it, he can take some more time as the process includes the removal of the old heater. The old heater’s drainage, disconnection and removal method takes approximately 40 to 60 minutes.

After removal, he can take 30 minutes to safely unbox the new heater and place it in the correct position. The connection of lines and power supply isn’t easy and quick, but a certified plumber from Grahams & Sons plumbing can do it in just 50 to 60 minutes.

In the end, the plumber will set it according to your demand, which can take 10 minutes. The whole process of replacement can take up to 2 to 3 hours, even with an expert plumber.
