## How do I know what size water pipe I have?

Measure the Outside Diameter (OD) of your pipe or pipe fitting:

1. Wrap a string around the pipe.
2. Mark the point where the string touches together.
3. Use a ruler or measuring tape to find the length between the tip of the string and the mark you made (circumference)
4. Divide the circumference by 3.14159.

## What size are residential water supply lines?

In most cases, the main pipeline from the street to your home is either 3/4 or 1 inch in diameter, supply branches use 3/4-inch-diameter pipe, and pipes for individual components are 1/2 inch. Remember that water pressure decreases by a half-pound per square inch for every foot pipes extend above your water supply.

In most cases, it’s your responsibility to maintain the supply pipe. This is the section of the service pipe from the boundary of your property – usually where the water meter and stop valve are – into the property itself.

## Does increasing pipe diameter increase water pressure?

The more water that is being forced through a pipe, the more pressure there will naturally be. Through any pipe size, higher water pressure will cause greater water flow. The pressure will decrease downstream, however, because of loss of friction and water velocity increase.

## What is the best pipe for main water line?

Galvanized Piping Galvanized metal is commonly used in construction, but pipes made from galvanized steel can be used in plumbing applications. This particular type of pipe is best used for water lines, as gas lines can cause the zinc to corrode and damage the pipe or block the entire system.

## Which is better copper or PVC for water main line?

Resists corrosion and impact damage better than copper pipe because plastic doesn’t corrode, and because PVC pipe is thicker than copper pipe. This means it’s better for areas where the pipe will be exposed in high-traffic areas. This is because PVC doesn’t conduct heat as well as copper does.
