Pool Service: Why Is My Pool Heater Making a Strange Sound?

If you’ve got an in-ground pool, you probably have a pool heater to help keep it comfortable during those cooler months. A broken pool heater means cold water, so it’s important to know how to determine if your heater needs some repairs and get the Pool Service Adelaide done on time.

One of the most common reasons why pool heaters start making strange sounds is due to air or gas leaks inside the heater itself. Fortunately, there are several telltale signs that indicate your heater may be leaking, and you can use them for troubleshooting before calling in a pool service technician.

Top Reasons Why Your Pool Heater Making a Strange Sound

Hard Water Scale

The reason for the strange noise is likely because your pool heater is clogged with hard water scale. If you haven’t been using the pool recently and you notice it’s making this noise, then this could be the problem.

We recommend using most reliable Pool Service Adelaide, like aluminium, to remove it from the pipes and maintain your pool so that this doesn’t happen again.

A Dirty System

A pool’s system contains pipes, valves, fittings, and filters. With time, debris can build up inside these parts of the pool’s system. For this reason, regular maintenance is needed to keep the system in good working order.

A buildup of debris in these systems often leads to strange noises coming from the equipment. In an older pool’s system, for example, debris may have built up, causing noise or rough operation from the pump when it starts.

This can be resolved by manually opening and closing some valves before starting the pump to release any air that may be trapped between components which would cause them to vibrate against each other and produce a sound that may seem like metal on metal. However, as pools age, so does their equipment – eventually becoming noisy or malfunctioning altogether.

Clogged burner orifice

The problem could be that the burner orifice, which is the tube through which natural gas flows into the burner, has become clogged. Often this is caused by calcium deposits. To solve this problem, we will have to turn off the power to the unit and clean it with a wire brush.

Then we can turn the power back on and see if the noise goes away. If not, there might be another problem that needs to be addressed, and we’ll need to contact one of our experts for further assistance.

The Faulty Pressure Switch

A clogged burner orifice can lead to inefficient use of gas, high levels of carbon monoxide in the pool water, and high energy bills. If your pool heater is making any weird noises and not heating the water like it used to, it might be time for some Pool Service Adelaide. With a little maintenance and care, your pool heater should provide you with years of dependable service.

Once you’ve gone through these steps, your pool heater should be good as new and working at peak efficiency again!
