The External Water Shut Off Valve and Its Importance in Home Plumbing

During and after the construction of homes attention is paid to plumbing as it is essential for day-to-day living. With the help of a properly maintained external water shut off valve, plumbing systems can be well catered to, not to mention the convenience this offers to every resident. This article examines the implications surrounding the external water shut off valve, its workings, and the importance of being proactive in its maintenance. 

What Is An External Water Shut Off Valve?

An external water shut off valve is very important within the plumbing systems of a house. Located outside the house, It secures the linkage between the internal plumbing network of the household and the municipal water supply system. Its main utility is segmentation of the inline water supply for particular areas of the house so that maintenance, servicing, and emergencies can be dealt with efficiently. 

Types of External Water Shut Off Valves

Water shut off valves are classified differently based on their structures, each having their pros and cons:

1. Gate Valves. These valves are opened and closed by the lifting of a gate either in the way of water flow or out of it. Since they are reliable in fully closing or opening the water supply, they tend to be widely used. However, like many other water valves, they do not serve well in water flow regulation.

2. Ball Valves. These are the most durable and simplest to use. A valve with a hole at the center of a rotating sphere is employed here. A water shut off is enabled with a quarter turn of the valve. 

3. Butterfly Valves. The water flow is controlled through the opening and closing movement of a rotating disc. They are small and handy for fast shutoffs, but may not be as tight as the ball valves. 

4. Plug Valves. These valves are the same as the ball ones, but instead of a ball, a cylindrical or tapered plug is used to block the water. Plug valves are flexible and provide on/off options, as well as flow regulation.

Significance of the External Water Shut Off Valve

1. Emergency Cases

During emergencies like a pipe burst or severe leakage, it is important to be able to cut off the water supply quickly to reduce water damage. Water logging leads to massive damage to the property, which in turn incurs excessive repair costs. This is why an external shut off valve is most important.

Let’s say you are out of your house and a leak occurs. If the shut off valve is not working properly, water may flow infinitely and damage your floors, walls, personal items, and so much more. This valve can be managed by you or your neighbor and acts as a protective measure. 

2. Preventative Maintenance

In most situations when working on the fixtures or maintenance in a plumbing system, shutting the water supply off is required. With this external shut off, a home chore can be completed without concerning the well-being of the entire neighborhood, allowing for simple and effective repairs. 

If you are simultaneously enhancing the bathroom fixtures and fixing the leaking fixture, shutting off the water flow from the source is critical for maintaining a leak free work environment and aids in completing the task efficiently without having to worry about hoses getting activated accidentally. 

3. Reduction of Water Usage 

Accessibility usually comes with a price. Minor leaks can be ignored but result in increased water and utility bills. An external shut off valve addresses the problem as soon as it is noticed, helping conserve water and save money.

Also, in areas with droughts or water scarcity, controlling the water supply becomes very important. You could efficiently manage the system associated with your home and do maintenance and repairs by separating the system to avoid unnecessary water wastage. 

Tips to Find Water Shut Off Valve Outside the House

It’s important to note that shut off valves aren’t as easy to locate as they sound. Older houses, especially, require some digging in order to find the shut-off valve. Here are some pointers:

1. Look at the Property Plan: The shut-off valve is usually on the outer side of the property next to the entrance, parallel to where the main pipe connects the house. You should look for a metal box or cover placed horizontally in the yard.

2. Follow the Pipe: Head to the street or the well and observe the course of the primary water pipe, follow it to where the valve is situated. 

3. Examine Title Documents: Look at the property information or the report that got prepared because of the house’s inspection. There may be some visual patterns/ brazilian jiu jitsu that can tell you where the valve is placed.

4. Ask a Specialist: A certified plumber will certainly be able to find the valve for you if you are facing trouble locating it.

Some Useful Suggestions for Finding That Valve

– Make sure to check the area around the water meter because now a days it is common to place tubes that lead to the wall or foundation close to the meter.

– If you are living in areas where temperatures drop, some valves are snow or ice proof, meaning they are put in a casing that doesn’t allow any of the parts to freeze.

– In the case that your house belongs to a homeowner’s association, check with them regarding maps or for assistance in locating the common utility connections.

Operating the External Water Shut Off Valve

Knowing how to operate the valve is crucial:

– Identify Valve Type: There are two common types of valves: gate valves and ball valves. Gate valves require multiple turns to either open or close, while ball valves can be opened with a quarter turn.

– Turn Off the Valve: Remember that gate valves are closed by turning the handle clockwise until it stops and ball valves are closed by turning the valve a quarter turn until it is perpendicular to the pipe.

– Verify Water Shut Off: After closing the valve, turn on a faucet to relieve any pressure in the pipes. Check inside the house to confirm that water flow has ceased.

Precautions When Operating The Valve

– Be cautious when turning the valve handle. Apply gentle pressure as using too much can snap the handle if a valve has not been in use for sometime.

– Never force a stuck valve open, instead lubricate if necessary spray or seek out a skilled expert; doing so can damage the valve.

How to Maintain the External Water Shut Off Valve

To ensure that the valve is operating correctly when you need it, follow these guidelines:

– Annual Inspections: Inspect the valve at least once a year to ensure functionality and check for rust or corrosion.

– Clear the Surrounding Area: Ensure that the space around the valve is free from vegetation, debris or any other obstacles to make access easier during emergencies.

– Replace When Necessary: If the valve shows signs of hard operation or deterioration, contact a professional for replacement.

Additional Maintenance Tips

– In order to prevent the valve from seizing, make sure to lubricate the valve stem at least once every year.

– Inspect around the valve for any signs of leaks, which could indicate repair or replacement needs during the inspection.
