Hot Water Cylinder Installation

Want to get into hot water?

In our lives, hot water is one of the most important goods in our households, whether for a shower in the morning or a relaxing bath at the weekend: For most people, well-tempered and well-pressurised water available throughout the house is more than just a basic need; it is a feature of high quality of life and wealth.

Throughout the Rodney district and New Zealand, hot water cylinders are the most common and convenient hot water heating systems. They can last a long time if properly maintained. However, there comes a time when your existing unit starts to give you problems, and you suddenly find yourself without hot water and therefore without a hot shower or bath.

What if you are running out of hot water or the water pressure is too low? Is your hot water smelly? Is the water temperature fluctuating? Do you have a high power bill?

We will make an on-site assessment, identify the problem, and, if possible, fix your hot water cylinder’s fault promptly. It is worth checking with our experienced service team whether we can repair your hot water cylinder before rushing into an expensive hot water cylinder replacement.

Hot Water Cylinder Problems

Hot Water Cylinder Leaking

If your hot water cylinder starts to leak, this is usually a sign that it is nearing the end of its lifetime and probably needs to be repaired or possibly even replaced ASAP.

The reasons for leaking hot water cylinders vary and are often difficult for a layperson to identify. It is best to contact an expert to find out exactly what needs to be done.

Hot Water Cylinder Overflowing

If you recognise the overflow is continually running, this could indicate an expansion or valve problem of your hot water cylinder.

You should repair an overflowing hot water cylinder or hot water system as soon as possible only by an expert for your safety. This is not a DIY job as the manufacturers prohibit it.

Running Out Of Hot Water

Are you constantly being left with no hot water? It might happen because of the size of your tank or change of consumption. Also, the age of your hot water cylinder can be the cause.

There are some simple things you can check on the hot water cylinder first before calling us. It will help our technicians to diagnose the problem and give the best advice.

Low Water Pressure

If there is significantly lower pressure at your hot water taps than at the cold ones, or you suffer from a weak shower, your hot water cylinder is probably on low water pressure.

Most new fittings and appliances such as dishwashers are only designed for mains pressure. Upgrading to mains pressure will offer you great options for an even flow in the house.

No Hot Water

Is there only cold water but no more hot water coming out of the taps in your whole household? This may indicate a severe problem with your hot water cylinder.

If hot water stops flowing from your taps in your house, there are various elements in your hot water cylinder that could be faulty and may need an inspection and repair by a professional


Hot Water Cylinder Leaking

Reasons for hot water cylinder leaks

  • Loose connections
  • Faulty element washers
  • Faulty valve
  • Excessive pressure
  • Thermal expansion or contraction
  • Cracked tank caused by excessive pressure, overheating or age.

What to do about hot water cylinder leaks

1. Turn off the water tap

Turn off the inlet from which the water flows into the hot water cylinder. If you are not sure which is the right tap, turn off the whole water supply to the household. This tap is usually at the front of your property along with the water meter.

2. Switch off the power

Go to your switchboard and turn off the switch labelled “hot water cylinder”, “water heater” or just “cylinder”. This will ensure that the hot water cylinder elements do not burn out when it starts draining.

3. Empty the cylinder

The hot water cylinder stops leaking as soon as the cylinder is draining. This may mean that you have to turn on the hot water taps in your house to drain the water.

4. Call Aqua Works

A leaking hot water cylinder is a job for an expert. Give us a call on 0800 AQUA WORKS for a trustworthy and safe repair or replacement service to stop the leak.

Get hot water flowing

A leaking hot water cylinder can be caused by many different issues that are sometimes difficult for a layperson to identify. The safest and the best way forward is to call Aqua Works. We will make sure that you can enjoy hot water in your home again as quickly as possible.

Hot water cylinder overflowing

Reasons for overflowing hot water cylinders

  • Relief Valve (high pressure)
  • Pressure reducing valve (low pressure)
  • Faulty thermostat

What to do about hot water overflows

There is not much you can do about an overflowing hot water cylinder. If your relief valve is constantly running, you need to contact us. It is too dangerous for an unqualified person to search for the reason themselves.

However, to verify whether the overflowing of the hot water cylinder is caused by normal expansion or a faulty valve, you can consider doing the following:

  1. Switch off the power supply to the hot water cylinder for about 5 minutes.
  2. If the hot water cylinder’s dripping stops due to the interrupted power supply, it is a normal thermal expansion.
  3. If the hot water cylinder’s dripping continues after cutting off the power supply, the pressure reducing valve is probably faulty.

In any case, your safety should always come first. Give us a call on 0800 AQUA WORKS for a trustworthy and safe repair or replacement of your overflowing hot water cylinder.

Reasons for no hot water

  • Damaged thermostat

  • Broken pipes

What to do when you have no hot water

If you suddenly run out of hot water when you take your morning shower, it not only feels cold and uncomfortable, it could also frighten you. But don’t worry!

Constantly running out of hot water can be caused by several issues. You might want to consider and check the following reasons:

  1. The size of your tank must fit your consumption. If it is too small, it will not supply sufficient hot water.
  2. The age and regular maintenance of your hot water cylinder have an impact on your hot water supply.

Your hot water system consists of various components that must work together perfectly to provide your entire household with hot water. If any part of your hot water cylinder is not working correctly, this will affect the amount of hot water available.

Call us on 0800 AQUA WORKS to ensure that you will not run out of hot water in the near future.

Low water pressure

Reasons for low water pressure

  • Older model of hot water cylinder
  • Faulty pressure reducing valve
  • Incoming pressure fluctuations
  • Problems/blockages with tap or/ and valve
  • Exceeded debris or sludge clogging the outlet

What to do about low water pressure

Low pressure hot water cylinders from the 1970s can still be found in many houses in New Zealand. However, these older water heating systems often have problems when several hot water taps are used simultaneously in different areas of the home.

Low pressure hot water cylinders still enjoy great popularity. Especially in rural areas, they are a standard option for a like-for-like replacement. However, the sustained trend here is to upgrade them to mains pressure, although it is still possible to pump bore/ tank water to mains pressure.

There are many different ways to heat water at a constant pressure throughout the house. By replacing your low pressure hot water tank with a modern model, you will meet your needs and desires for smarter, more pleasant water flow in the home. Get in touch to talk with us about mains pressure hot water cylinder installation at your place.

Call us on 0800 AQUA UV, and we upgrade you to full flow.

What to do when hot water systems go bad

For many people, nothing beats a hot shower in the morning. But what if it suddenly turns cold without your intervention?

There are simple reasons for the loss of hot water in your household that do not indicate a fault with your hot water cylinder. Before calling the Aqua Works service team, you could verify the following points:  

  1. Check if the mains isolator switch next to your hot water cylinder is in the “On” position.
  2. Check in the electrical switchboard of your house whether the circuit breaker labelled “Hot water”, “HWC” or “Hot Water Cylinder” is switched on.
  3. Check your meter box outside your house to ensure the hot water circuit switch is turned on.

For any other problem, you must call the experts on 0800 AQUA WORKS. Depending on the issue, we send either one of our electricians or qualified plumbers to assist you in solving your hot water cylinder issues.
