What size water line do I need to run 500 feet? The size of the water line needed to run 500 feet depends on the flow rate and pressure requirements of the system. A 1-inch or larger pipe may be necessary for longer distances to maintain adequate flow and pressure.
Is it cheaper to have a water meter? Whether it’s cheaper to have a water meter depends on your water usage. Some people may save money with a water meter if they use water efficiently, while others may not.
Can a water meter be removed once installed? Removing a water meter typically requires approval from the water utility company and may not be allowed in many cases.
