What factors affect the cost of replacing the main water shut-off valve?
Type of Water Shut-Off Valve
|Gate valve||$10 to $50|
|Ball valve||$10 to $20|
|Stop-and-waste valve||$10 to $50|
|Globe valve||$10 to $25|
|Fixture valve||$50 to $150|
There are several types of water shut-off valves, and the type you choose can significantly affect your replacement cost. Some types may be hard to install, so plumbers will naturally charge more.
Gate valves and ball valves are typically used for main water pipes because they are more robust than other lines and can handle the entire water supply. However, there are also other valves that you can consider.
Gate valves are the more traditional type of shut-off valve and are quite durable. Depending on the brand and material, a gate valve unit can cost $10 to $50.
Ball valves are also popular shut-off valves, and they are considered to be more reliable than gate valves. They typically cost $10 to $20.
Stop-and-waste valves are mainly used in sprinkler lines and are buried in the ground. These valves can cost anywhere between $10 and $50.
Globe valves aren’t usually used as main water shut-off valves in residential areas, as they’re mostly used in large-scale industrial processes or HVAC systems. However, if you do choose them for your home, you can expect to pay $10 to $25.
Fixture valves can either be angled or straight, and they’re mostly used for specific water lines. Using it as a main shut-off valve should only be temporary, as they may not be able to handle the entire water system.
These valves can cost anywhere between $50 and $150.
Material of Water Shut-Off Valve
|Brass||$10 to $40|
|Bronze||$20 to $250|
|Stainless steel||$20 to $550|
Water shut-off valves can be made with different materials, and each material comes with a different price range. The three most commonly used materials are brass, bronze, and stainless steel.
Brass is the most commonly used material for main water shut-off valves. It offers excellent durability, corrosion resistance, and strength.
Its price usually ranges anywhere from $10 to $40, making it a lot more affordable than other materials.
Bronze valves, which are made from a combination of copper and tin, are considered to be more durable than brass, so they’re also a bit more expensive. They can cost anywhere between $20 and $250.
As for stainless steel valves, they tend to be the most expensive, as they can handle high pressure and high temperatures. They can go for as low as $20 and as high as $550.
Labor cost is typically the biggest contributor to the cost of replacing the main water shut-off valve.
The complexity of the job, the experience and skill level of the plumber, the location of your home, and the personal discretion of the plumber can significantly affect the overall cost of replacement.
The average labor cost for plumbers is anywhere between $20 and $50 per hour. The more complex the job, the longer it will take for the plumber to fix it, and the higher the cost will be.
On average, the overall labor cost for replacing a water shut-off valve can go from $170 to $250.
Location of Water Shut-Off Valve
|Basement||$180 to $220|
|In-ground at water meter||$180 to $500|
|Vault or box||$200 to $750|
|Underground||$240 to $1,000|
If the location of the water shut-off valve cannot be easily accessed, the work will require more effort from the plumber. This will also result in longer working hours and, in turn, higher costs.
If specialized equipment is needed to gain access to the main water shut-off valve, then the cost will also increase.
Water valves located in basements and in-ground at water meters are typically easier to access, so the cost of replacement is also more affordable.
For water valves located in a basement, expect to pay anywhere between $180 and $220. For those located in-ground at water meters, replacement costs typically range from $180 to $500.
Shut-off valves located in vaults and boxes are usually more expensive to replace, as they can be harder to access. The replacement cost for these valves usually ranges from $200 to $750.
The most expensive ones to replace will be the ones deeply buried underground, as they require more work from the plumbers. The cost for this type of replacement can go from $240 to $1,000.
What additional costs should I consider when replacing a main water shut-off valve?
Additional costs that you need to consider when replacing a main water shut-off valve are permit fees and emergency fees.
Some cities and states require homeowners to obtain permits before replacing a main shut-off valve. Hence, it’s always advised to check your local regulations before making changes to your home.
Generally, permit fees can range between $50 and $500. These prices can vary if your city requires you to pay an application fee or inspection fee.

How much does it cost to replace a main water shut-off valve by yourself?
