Main Water Valve Turned Off But Water Still Running: Fixed!

You might feel confused and worried when you turn off your main water valve, yet water keeps running. It’s frustrating, right? You expect everything to stop, but it doesn’t. This can happen for a few reasons, and luckily, there are ways to fix it. In this article, I will guide you through simple, clear steps to understand why water keeps flowing and how to stop it safely. You’ll learn what to check and what to do next to get control over your water again.

Check If You Turned the Right Valve

When the main water valve is turned off but water still runs, the first thing to check is if you really turned off the main valve. Sometimes, there are multiple valves, and it’s easy to get confused.

The main valve usually is where the water line enters your home from the street or meter. It can be a round handle or a lever. If you only turned off a smaller valve inside the house or a valve that controls just part of your home, water can still flow from other pipes.

Look carefully near your water meter or where the water line comes into your house. If you see more than one valve, try to identify which one is the main shutoff. Turning off the wrong valve will not stop all the water.

Also, some homes have a valve outside near the street or in the basement; make sure to check those places. It’s a good idea to label your valves once you find the main one to avoid confusion later.

If you find the right valve and it feels stuck or hard to turn, try to gently work it back and forth. Don’t use too much force or tools that can break it. Sometimes valves get old and rusty and might need replacing if they don’t fully close.

• Confirm you turned off the main water valve, not just a smaller valve.
• Locate the main valve by the water meter or where water enters your home.
• Check for valves outside or in the basement.
• Gently try to turn the valve fully closed.
• Label the main valve for future reference.

Look For Leaks or Broken Pipes

Even if you have turned off the main valve properly, water might still run if there is a leak somewhere in your plumbing. Pipes can crack, joints can break, or fixtures can drip.

This leaks water out, making it seem like water is still running. A common spot is around toilets, faucets, or under sinks. Sometimes the water pressure can push water through cracks or broken seals.

To find leaks, start by listening for dripping or running sounds. Walk through your house and yard checking for wet spots, puddles, or unusual damp areas. You might smell mold or see water stains on walls or floors.

Outside, look near your irrigation or sprinkler systems for leaks. Also, check your water meter: turn off all water inside, then watch the meter. If it keeps moving, you likely have a leak somewhere.

Fixing leaks can sometimes be easy, like tightening a loose faucet or replacing a washer. Other leaks might need a plumber’s help, especially if pipes are underground or inside walls.

• Listen for dripping or running water sounds.
• Check for wet spots or puddles inside and outside.
• Watch your water meter when all water is off.
• Tighten or replace leaking fixtures.
• Call a plumber for hard-to-reach leaks.

Test Your Water Meter and Valve Function

Your water meter and main valve work together to control water flow into your home. If the valve looks closed but water still flows, the valve might be broken or the meter might be faulty.

Sometimes the valve handle turns but doesn’t close the valve fully inside. This can happen with old or damaged valves. Or, the meter might register water even if the valve is off because of internal leaks or malfunctions.

To test your valve, shut off the valve completely and watch your water meter closely. If the meter keeps spinning, water is still passing through. This means the valve isn’t working right and might need repair or replacement. If the valve is broken, don’t try to force it too much because it could break completely and cause more water damage.

If you suspect the meter is the problem, contact your water company. They can check and replace faulty meters. It’s important to make sure both the valve and meter are in good shape to stop water when you need it.

• Turn the main valve fully off.
• Watch your water meter to see if it stops.
• If the meter moves, valve may be broken.
• Avoid forcing broken valves.
• Contact water company if meter seems faulty.

Shut Off Water Inside the House to Control Flow

If the main valve won’t stop water, your next option is to shut off water inside the house to control the flow. This means closing valves on individual water lines, like under sinks, toilets, or to appliances like washing machines or dishwashers. These smaller shutoffs can help stop water to specific areas if the main valve is not working well.

Start by closing valves to the rooms or fixtures where you see leaks or running water. For example, if your toilet is running, close its valve behind it. If a sink is leaking, close the valve under it. This helps stop water flow to problem spots and prevents flooding or damage while you fix the main valve.

Also, turn off water heaters and appliances if you can’t stop the main water flow. This avoids damage to them if water pressure changes suddenly.

• Close valves under sinks, behind toilets, or near appliances.
• Target valves in problem areas first.
• Turn off water heaters and appliances.
• Use this method as a temporary control.
• Plan to fix the main valve soon for full control.

Replace or Repair the Main Valve

If the main water valve is faulty, it may need to be repaired or replaced. Valves can wear out over time and stop working properly. Signs of a bad valve include leaking around the valve, difficulty turning the handle, or water flowing even when it’s fully closed.

Replacing a main valve is not always a simple job, especially if it’s an older style valve or if it is underground. It may require shutting off water from the street temporarily and calling a professional plumber. Some valves can be fixed by replacing internal parts, but sometimes a full valve replacement is necessary.

It’s important to fix the valve quickly to avoid water damage and to be able to control water in emergencies. After replacement, test the new valve several times to make sure it fully shuts off water.

• Look for leaks and stiffness in the valve.
• Decide if repair or replacement is needed.
• Hire a plumber for complex valve work.
• Replace old or broken valves promptly.
• Test the valve after repair or replacement.

Use Emergency Measures to Stop Water Flow

If water keeps running and you cannot fix the valve right away, use emergency measures to stop the water. One way is to contact your water company and ask them to shut off the water at the street or meter. This stops all water to your home until repairs are done.

Another emergency option is to shut off individual fixture valves or drain pipes to release pressure. You can also use buckets, towels, and mops to manage water and reduce damage.

In severe cases, call a plumber immediately. Water damage can ruin floors, walls, and furniture quickly, so acting fast is important. Having a plan and knowing your valves beforehand will help in emergencies.

• Contact water company for street shutoff.
• Use individual fixture valves as backup.
• Drain pipes to relieve pressure.
• Use towels and buckets to control leaks.
• Call a plumber immediately for help.

Final Thoughts

Dealing with water running after turning off the main valve can be stressful. But understanding your valves, checking for leaks, and knowing how to act can help you control the situation quickly. Remember, finding the right valve, testing it, and repairing if needed are key steps. If you can’t fix it yourself, don’t hesitate to call professionals. Taking quick action saves you from costly water damage and keeps your home safe.

Frequently Asked Questions (FAQs)

Is it normal for water to keep running after main valve is off?

Yes, it can happen. Sometimes the valve does not fully close, or there is a leak somewhere in the plumbing. Old valves can get stuck or broken, letting water flow even when turned off. Also, if the valve is not the main shutoff or if there are multiple valves, water might still flow through other pipes. It’s important to check the valve condition and any leaks to fix the issue properly.

Can I fix a broken main valve myself?

Fixing a broken main valve can be difficult, especially if it is old or underground. Some minor valve repairs, like lubricating or gently turning it, might be possible for beginners. However, replacing or repairing the valve inside the water line often requires plumbing tools and shutting off water from the street, which is risky without experience. It’s best to call a professional plumber for safety and proper repair.

Do I need a plumber if water still runs after shutting off valve?

If water continues running after turning off the valve, it is wise to call a plumber. The valve might be damaged, or there could be hidden leaks in your plumbing. A plumber has the tools and knowledge to find and fix these problems safely. Trying to fix complicated plumbing issues yourself can cause more damage or flooding.

Is it possible for the water meter to be faulty?

Yes, water meters can malfunction. A faulty meter might show water usage even when water is off, or fail to register actual flow. If you suspect the meter is wrong, contact your water company. They can test or replace the meter. A broken meter can confuse you about your water use and hide leaks.

Can water pressure cause water to flow after valve is closed?

Sometimes, water pressure in pipes can force water past a partially closed valve, especially if the valve is old or damaged. Pressure can also cause small leaks to drip continuously. Managing water pressure with a pressure regulator and keeping valves in good condition helps prevent this issue.

Do I need to shut off water inside the house if main valve doesn’t work?

Yes, shutting off water to individual fixtures can help control water flow if the main valve is not stopping water. Closing valves under sinks, toilets, or near appliances limits water in those areas. This is especially useful to prevent flooding while waiting for repairs.

Is it safe to use tools to force a stuck valve?

No, forcing a stuck valve with tools can break it and cause major leaks or water damage. If a valve is hard to turn, try gentle back and forth motion. If it still doesn’t move, call a plumber to avoid breaking it.

Can the water company shut off my water if the valve fails?

Yes, the water company can shut off water at the street or meter if your home’s main valve fails. This is an emergency measure to stop all water entering your property. Contact them if you cannot stop water flow yourself.
