Why You Might Need to Turn Off Your Water Supply

Common reasons to turn off the water supply to your St Marys property include:

  • Performing plumbing repairs or scheduled maintenance like replacing fixtures or pipes
  • Installing new appliances such as gas hot water systems, dishwashers, or washing machines requires a few steps but is critical for proper setup
  • Installing upgrades such as tankless water heaters and essential kitchen fixtures
  • Addressing burst water pipes, broken taps, or malfunctioning appliances connected to the water line
  • Preventing water damage when going away for prolonged periods

Issues with flexible braided hoses are another reason to shut off your main home’s water, as they can affect the main valve. Knowing how to operate your water meter and shutoff valve for water cessation enables swift plumbing issue resolution.

If the flexible hose connecting to your inside stop valve bursts, turning your water off promptly is key to halt the flow and prevent flooding damage.

By learning in advance how to shut off your water valves, you’re prepared to act quickly and minimise damage. The experts at St Marys Plumbing have the tools and knowledge to assist if you encounter difficulties accessing or turning off your property’s water supply.

Locating the Main Water Shut-Off Valve

Finding the main shut off valve is the initial, essential step in controlling the water your mains provide. This main valve serves as the principal control - once sealed, it helps you turn off your mains water ingress to your property.

In most homes, the water shutoff valve is located near the meter box, often referred to as the inside stop area.

Examine the front boundary area of your house for the meter box, as it’s commonly situated there for water authority access. The meter box contains pipes and valves; the largest valve with a handle is generally the main water shutoff to use as needed.

If there’s no external meter box, your water shut off valve could be located just inside your property. Common spots include under kitchen sink where you may find the water shut off valve, on the laundry wall behind washing machines, or even outside next to your home’s tap. Inspect the pipework near your laundry area’s floor or in similar spaces for handles or wheel-shaped valves that indicate shutoff mechanisms.

An alternative method for plumbing management is pinpointing isolation valves, which can look different depending on your setup, and are also known as the stop tap – a critical component in understanding how to turn off water. Stop taps can isolate the hot and cold water individually just before it enters your home. To locate them, trace the two large pipes poking out from your exterior wall near ground level.

If searching near your external taps or kitchen yields no results, it might be necessary to gain internal access such as investigating how turn off valves within cupboards. Inspect around major appliances such as dishwashers or your water heater to find the shutoff valve. Should you remain unsure about locating your shutoff valve, perusing your home’s blueprints may provide insightful plumbing information, or alternatively, call us at St Marys Plumbing for direct advice.

After a bit of searching, you’ll easily find the main water shutoff valve on your property. Turning the valve handle clockwise will effectively shut off the water to your home. If you have any trouble completing this process, St Marys Plumbing offers complimentary assistance - email or call our office.

How to Operate Your Main Water Valve

After locating the main water off valve for your home, carefully turn it to stop the main water supply. Here is a step-by-step process:

  1. Ensure all taps inside your home are turned off first to avoid undue water pressure building up in your water main system.
  2. Use both hands to grip the valve handle firmly.
  3. Turn the handle clockwise in a slow, controlled manner around 90 degrees. You’ll feel some resistance initially before it spins more freely.
  4. Persist in turning clockwise until the valve handle is perpendicular to the pipe, effectively stemming the water flow into your home. This action conclusively halts the water supply, ensuring no water enters your home’s plumbing system.
  5. Go back inside and turn on a tap to check that water is no longer flowing - the flow should cease entirely once the main valve is shutoff.

Following these instructions, you can effectively cut off the main water supply via the primary valve at your property. Shutting off the water using the proper process prevents leaks or damage from occurring.

Should you encounter any challenges in finding or operating your water shutoff valve, our licensed plumbers are ready to assist; just reach out to our team. Email or call our office and we’ll promptly send out an experienced technician.

Turning Off Individual Fixture Valves

Aside from the main water shutoff valve, individual stop valves may be fitted to water lines that supply certain home fixtures and appliances.

These individual fixture valves allow you to selectively manage your plumbing system, switching the supply off to specific taps, toilets, washing machines, dishwashers and other items. Locating them simply involves tracing the water supply pipes connected to the fixture back to the valve.

Finding your dedicated valves for individual appliances is useful when shutting off water, such as:

  • Conducting repairs or maintenance on the fixture itself
  • Replacing old appliances with new ones
  • Troubleshooting leaks coming from a specific location

Turning the valve connected to your fixtures until it’s perpendicular to the pipe effectively stops the water supply while keeping the rest of your plumbing functional. This targeted approach helps reduce disruption compared to shutting off the main supply.

Remember this option next time an appliance like your washing machine springs a leak. Simply use the dedicated stop valve to cut off the water until a plumber can attend to repairs. This can limit the potential for flooding damage.

St Marys Plumbing’s licenced technicians have extensive experience locating these valves across various makes and models of plumbing systems. Email or call us for professional assistance isolating tricky fixtures.

What to Do Before Turning Your Water Back On

Once you’ve completed necessary plumbing repairs, it’s time to reinstate your property’s water supply. However, take precautions on how do to proceed before turning your main water valve back on:

  1. Inspect all pipes, joints, valves, and fixtures thoroughly to ensure your water supply can be restored leak-free. Make sure to replace any damaged parts.
  2. Confirm all taps inside and outside your home are closed.
  3. For devices such as washing machines or dishwashers, make certain any individual stop valves remain off, understanding how turn them back on once you reconnect hoses.
  4. Open an outside tap and attach a hose. Aim the hose away from your home in case of residual leaks.
  5. Gently rotate the main water valve counterclockwise to resume the supply, and promptly inspect connections for leaks.
  6. Once water flows smoothly from the hose, close the outside tap and disconnect the hose.
  7. Systematically open each tap around your home starting closest to the main valve then working outward to bleed any air trapped in pipes.

Carefully reinstating the mains water supply allows you to verify the integrity of fittings and fixtures for leaks before the system is fully pressurised. This prevents complications like water damage.

Preventative Maintenance of Your Water Valves

Understanding how to operate your main water shutoff valve is as important for home maintenance as it is for emergencies, so regular inspections of all water valves on your premises is wise.

Conducting preventative maintenance checks on valves like your main shutoff, individual fixture stop taps, and flexible appliance hoses can uncover issues before they cause major leaks or flooding.

Here are some tips for maintaining your water valves:

  • Test your main water shutoff valve every 6 months by turning it on and off. This ensures you can confidently turn off water main smoothly when needed.
  • Inspect exposed pipework and connections for corrosion annually. Replace any deteriorating valve fittings.
  • Check washers and seals inside tap valves for cracking or wear every 1-2 years.
  • Confirm flexible braided hoses connecting appliances are firmly attached and free of bulges or cracks.

Remembering to periodically inspect your St Marys property’s various water valves lets you address minor leaks or operability issues before major problems arise.
