Installing a new water line to your house is a project that will take some time, but is not difficult.
Locate Your Water Supply
Call your local water company to find out where the main water supply is located. If you are near a main water valve, you will see it sticking out of the ground. A private water supply, such as a dug well, will have a well cover sticking out of the ground.
Your water pipes need to be buried to protect them from freezing temperatures or other problems that could damage them. Dig a trench from the water source to your basement, garage or other building where you want the water.
Find Correct Pipes
Once you have the hole dug you will have to make the connections for your pipes. You will need to what type of connections you need. In most cases, it is a threaded fitting and PVC piping.
Chances are you will not get a long enough pipe to go from your water source to the home. Measure off the PVC pipe and cut to size with a hack saw. Use PVC glue to connect each pipe where you need to.
Use PVC couplings to connect to the threaded end of the water supply and into your home. Check for any leaks and then bury your pipe.
