shutoff valve

Most homes and buildings in Australia rely on an intricate plumbing system, so it’s important to become familiar with the key parts, such as the main water shutoff valve. 

This guide will explain the fundamental aspects of this important component, which controls water flow to your property and could be a potential lifesaver in the face of an unforeseen water emergency. 

The Role of the Main Water Shutoff Valve

The main shutoff valve, commonly known as the water main, is your home’s primary control point for water flow. It’s typically located at the front of your house, kept safe under a council cover plate. 

This key component in your plumbing system comes with a lever that allows you to open or close the valve. Doing so facilitates the activation or termination of your water supply or isolates a portion of your plumbing network from the rest of the system as needed. 

For instance, the shutoff valve is critical when facing a plumbing emergency like a leaking pipe. By turning it off, you can quickly stop the water flow and prevent further damage to your property. 

Turning off the main shutoff valve might also be necessary when replacing it or when performing certain maintenance and repair tasks for your plumbing system. 

Operating the valve is straightforward. You turn the valve lever clockwise to close it and cut off the water supply. If it’s stiff and doesn’t turn easily, you can use tools like a screwdriver or pliers to aid you. 

However, if you still cannot budge it, it’s best to call for the help of a licensed plumber. We are trained in dealing with such issues and can ensure the shutoff process is handled safely and correctly.

Types of Main Water Shutoff Valves

The design of these shut-off valves typically features a lever that, when either turned or rotated, interacts with a gate-like component to control water’s passage. 

Now, let’s explore some of the common types of shutoff valves you’ll find in Australian homes: 

Ball Valves 

Regarded as one of the most commonly used shutoff valves, ball valves are highly efficient in regulating water flow. 

They are easily recognised by a round lever, often marked with ‘on’ and ‘off’, which indicates the valve’s state. 

When the lever aligns with the pipe, water can flow freely, whereas a 90-degree turn of the handle stops the water flow by closing the valve. 

Gate Valves 

Although differing operationally from ball valves, gate valves are equally effective at managing water flow. Instead of a rotating ball to block or allow water’s passage, gate valves utilise a ‘gate’ that is raised or lowered by turning a wheel handle. 

T-Top Isolation Taps 

Popular in many Australian residences due to their ease of use, T-top isolation taps are notably characterised by their T-shaped top. Water flow can be efficiently controlled by turning the T-handle in either a clockwise or anticlockwise direction. 

How to Locate Your Main Water Shut-Off Valve

In many Australian residential buildings, these crucial components are often found outside, near the water source itself. The shut-off node is often shielded by a council cover plate, particularly at the front of the house. This location is typical but may differ based on specific property characteristics and local water network design. 

In apartment-style constructions or urban establishments, the valves are more likely to be tucked away inside – often within kitchen or bathroom cupboards. 

Checking these key areas, you should come across a lever or wheel, typically the shut-off valve controlling the water flow to your property. If you cannot locate your shut-off valve, feel free to ask a professional plumber or contact your state’s government water agency for assistance. 

Common Issues with Main Water Shutoff Valves

As with any vital household mechanism, the main water shutoff valve may face certain challenges or develop faults over time. Understanding these common issues can help you diagnose snags early and take prompt action. 

  • Stiffness: One of the most prevalent issues homeowners often encounter is a stiff valve, making it challenging to initiate the shut-off process. This is usually a consequence of prolonged inactivity.
  • Leaks: In some circumstances, a defective valve may trigger an unexpected leak. A shutoff valve leak can hike up your water bill and, in worst-case scenarios, lead to water damage within your property.
  • Failure to turn off completely: When a valve fails to stop the water supply even when fully shut completely, it’s likely an indication something is amiss. Debris or a damaged washer may be the culprits in these instances.

Most of these issues are resolvable with a bit of maintenance and, occasionally, a replacement.

Maintaining Your Main Water Shutoff Valve

Maintaining your main water shutoff valve is essential to ensuring its durability and effectiveness in controlling water flow to your property. Regular maintenance not only extends the valve’s life but also prevents potential plumbing emergencies. 

  • Regular checks: Make it a habit to check your valve at regular intervals. This allows you to catch issues in their early stages and get them fixed before they escalate.
  • Keep it clean: Dirt and debris accumulated around the valve can hinder its functioning. As such, keeping the area around the valve clean is necessary to maintain it.
  • Exercise the valve: Like any other mechanical device, the valve must be exercised regularly to stay in good working condition. This exercise involves turning your valve on and off a few times. Remember to do this gently to avoid causing damage.
  • Professional Inspection: It’s prudent to involve a professional at least once a year for an in-depth inspection and maintenance of your valve. They will use their expertise to identify and address any issues relating to wear and tear or malfunctioning.

Remember, every property owner in Australia is responsible for maintaining their main water shutoff valve to keep it operational. This way, you have the control to manage any emergency water situations by simply turning this valve off.

Did you know the average cost to replace a main water shutoff valve ranges from $150 to $300?

Steps to Turn Off Your Main Water Supply in an Emergency

If you are in a plumbing emergency, such as a burst pipe or uncontrollable water leak, you must act swiftly and decisively. Here are the steps to guide you through this process: 

  1. Firstly, you need to locate your main shutoff valve. In many Australian homes, the valve is usually positioned at the front of the property, typically under a council cover plate. But in apartments or older properties, it might be under cupboards in the kitchen or bathroom.
  2. Once you’ve found the valve, you’ll have to turn it off. This is done by turning the valve clockwise.
  3. If the valve is stiff or difficult to move, you might need tools such as a screwdriver or pliers to assist you. Remember to wear protective gloves for safety.
  4. If specific fixtures are involved in your plumbing emergency, identify any additional shutoff valves related to them. If a fixture has two valves for hot and cold water, it’s necessary to turn off both.

When to Call a Professional Plumber

Maintaining the inner workings of your home can be unnerving, especially when it comes to your main water shutoff valve. This crucial component can control your property’s entire water supply, making its proper maintenance and functioning pivotal. Issues with the main shutoff valve can sometimes arise, indicating the need for professional help. But what do these issues look like? Let’s break this down: 

  • If your water bill reflects an unusual increase, you may have a hidden water leak. This leak might be related to the main shutoff valve, necessitating a thorough inspection by a professional.
  • Low water pressure throughout your property could indicate an issue with your plumbing system, possibly linked to a faulty main shutoff valve.
  • Water leakage around the shutoff valve is another tell-tale sign of an issue. This wastes water and can lead to other complex problems over time.
  • If you notice that the valve’s handle is difficult to turn or completely immobile, it’s a clear indicator of a faulty main shutoff valve that requires immediate attention.

Attempting to tackle these issues by yourself could lead to more serious complications. Thus, professionals should be entrusted with diagnosing and repairing any problems related to the main water shutoff valve. 

Reaching out to a professional during the initial stages of potential trouble will save you time and money and prevent extensive damage to your property. So, if you spot any issue with your main water shutoff valve, don’t hesitate to contact us. The reassurance of a trained and licensed professional looking after your plumbing system is a relief that’s second-to-none.
