FAQs
What is the most common residential water meter size? The most common residential water meter size is typically 5/8 inch.
What size pipe is at my water meter? The size of the pipe at your water meter can vary, but it is often 3/4 inch or 1 inch.
What size are most water meters? Most water meters for residential use are 5/8 inch or 3/4 inch in size.
Is the water meter size the same as the pipe size? No, the water meter size is not always the same as the pipe size. Water meters are typically smaller than the incoming pipe to measure the flow accurately.
What size water lines do you run in a house? Water lines inside a house can vary in size, but common sizes include 1/2 inch and 3/4 inch for cold and hot water distribution.
What is the flow rate of a 3/4 meter? The flow rate of a 3/4 inch water meter can be estimated at around 15 to 20 gallons per minute (GPM).
How many fixtures can be on a 3/4 water line? A 3/4 inch water line can typically support several fixtures in a house, including sinks, showers, and toilets. The exact number depends on local plumbing codes and the specific fixtures’ water usage.
Can you use PEX for water meter to house? Yes, PEX (cross-linked polyethylene) can be used for water lines from the water meter to the house. It is a popular choice for residential plumbing.
Is 3/4 water line enough for a house? A 3/4 inch water line is usually sufficient for a typical residential house. However, the size of the water line may need to be larger if the house has a high demand for water or if local plumbing codes require it.
Why are water meters smaller than pipes? Water meters are smaller than the incoming pipes to create a constriction point that accurately measures the flow rate. This constriction allows for precise measurement without causing significant pressure loss.
What are the three types of water meters? The three common types of water meters are mechanical (including positive displacement and turbine meters), electromagnetic (mag meters), and ultrasonic meters.
What is the size of a meter? The size of a water meter for residential use is typically 5/8 inch or 3/4 inch.
Does water meter size affect pressure? Water meter size can have a minimal impact on water pressure, but it should not significantly reduce water pressure in a properly designed plumbing system.
What is the difference between a 1 inch and 5/8 water meter? A 1-inch water meter is larger in diameter than a 5/8 inch water meter, which means it can handle higher flow rates. The choice between them depends on the water demand of the property.
How do you hook up a PVC pipe to a water meter? To hook up PVC pipe to a water meter, you typically use threaded fittings or couplings that match the meter’s size and connect them securely with Teflon tape or pipe thread sealant.
What is the best pipe for the main water line? The best pipe for the main water line depends on local building codes and personal preferences. Common choices include copper, PEX, and PVC.
How much does it cost to run a water line 500 feet? The cost to run a water line 500 feet can vary widely depending on factors like the type of pipe used, terrain, labor costs, and permits. A rough estimate could range from $1,000 to $5,000 or more.

What is the average residential water flow rate? The average residential water flow rate can vary, but it’s typically around 6 to 12 gallons per minute (GPM) for a single-family home.
How many gallons per minute is a 3/4 pipe? A 3/4 inch pipe can handle a flow rate of approximately 12 to 15 gallons per minute (GPM).
Can you use 3/4 PEX for the main water line? Yes, you can use 3/4 inch PEX for the main water line in a residential application, but it should meet local plumbing codes and accommodate your water demands.
Is PEX A or B better? Both PEX-A and PEX-B are commonly used for plumbing, and the choice often depends on personal preference and local availability. PEX-A is known for its flexibility, while PEX-B is more rigid but can be less expensive.

Where should you not use PEX? PEX should not be used where it may be exposed to direct sunlight for extended periods, as UV radiation can degrade it. It’s also not suitable for high-temperature applications like hot water boiler lines.
How long does PEX last underground? PEX can last for many decades when installed underground, but the actual lifespan can vary based on factors such as soil conditions and water chemistry. It’s generally considered durable and corrosion-resistant.
Why can’t you use PEX outside? PEX is not recommended for outdoor use without proper UV protection because prolonged exposure to sunlight can degrade and weaken the material.
Should I use 3/4 or 1 inch PEX? The choice between 3/4 inch and 1 inch PEX depends on your water demand and local plumbing codes. 1 inch PEX can handle higher flow rates and may be required for larger properties.
Does a larger pipe increase water flow? Yes, a larger pipe diameter can increase water flow capacity, allowing for higher flow rates and reduced pressure drop. However, using excessively large pipes may lead to lower water velocity and potential stagnation.
Does water flow faster through a wide or narrow pipe? Water flows faster through a narrow pipe (assuming a constant pressure) because the cross-sectional area is smaller, causing higher velocity. A wide pipe allows for greater flow capacity but at a slower velocity.
Does the length of a pipe decrease water pressure? The length of a pipe can decrease water pressure due to friction loss, especially in longer pipes. Smaller pipe diameters also contribute to greater pressure drop over distance.
Which is the best water meter? The best water meter depends on specific requirements, such as accuracy, flow rate, and application. Popular choices include mechanical, electromagnetic, and ultrasonic water meters.
What is the difference between a water meter and a water flow meter? A water meter measures the total volume of water consumed, while a water flow meter measures the rate of water flow at a given moment. Water meters are typically used for billing purposes, while flow meters are used for monitoring and control.
Should a water meter be vertical or horizontal? Water meters can be installed in either a vertical or horizontal orientation, but it should follow local plumbing codes and the manufacturer’s recommendations.
Which is bigger, 1 meter or 1 inch? 1 meter is significantly larger than 1 inch. 1 meter is equivalent to approximately 39.37 inches.

How many water lines run into a house? A typical residential house has two main water lines: one for cold water and one for hot water. These lines branch off to supply fixtures throughout the house.
Does hot and cold water run through the same pipes? Hot and cold water typically run through separate pipes in residential plumbing systems to prevent mixing, although they may run parallel in some cases.
What are the three types of flow meters? The three common types of flow meters are mechanical, electromagnetic, and ultrasonic flow meters.
What is the most accurate way to measure water flow? Ultrasonic flow meters are often considered the most accurate way to measure water flow because they do not obstruct the flow and can provide precise measurements.
