Can I ground panel to water pipe?
If this is available you must run a grounding conductor to it from the panel. You must also have a grounding conductor ran to any metal water piping that is in contact with the earth before entering the house of at least 10 feet. That connection must be made within 5 feet of where the water pipe enters the house.
Why water pipe grounding is not recommended?
Water pipes have been used extensively in the past as a grounding electrode. Water pipe connections are not testable and are unreliable due to the use of tar coatings and plastic fittings. The NEC requires that at least one additional electrode be installed when using water metal pipes as an electrode.
How do I test my ground water pipe?
A cold water pipe can be used as a ground, IF, it is metal the entire length, and goes into the ground. You can also install a ground rod and use that. If your electrical panel is grounded to a ground rod, you can tap in there. If its grounded to a water pipe, you can attach to the water pipe.
When a metal water pipe is used as a grounding electrode?
Section 250.50 of the National Electrical Code (NEC) requires that a metal underground water pipe in direct contact with the earth for at least 10 feet or more be used as one of the grounding electrodes for the electrical service to the building.
Can you run plumbing pipes around a panel?
Because there are no other rules governing plumbing pipes around a panel, you can conceivably run them vertically along either side of the panel, but in no case should they interfere with the operation of the panel door or block access to the panel.
Where are the hot and cold water lines in a kitchen?
They include: Behind the wall, the 1/2-inch water supply pipes branch off from the main 3/4-inch hot and cold lines that run throughout your house, and the waste pipe connects to a drain line that empties into the sewer system.
What kind of pipe can I use for hot water?
CPVC (schedule 80) pipe is rated for use up to 200 degrees Fahrenheit. This makes it ideal for use on hot water lines in homes and businesses.
Can a electrical subpanel go underneath plumbing?
My answer is this: Code is clear – nothing above the service panel except a structural ceiling. In viewing this install I see the panel set INTO the stud space with a 2×4 plate (header like) above it. Therefore that should represent a structural ceiling as far as the panel is concerned.

How big of a pipe do I need to run a water heater?
As a general rule you can run 1/2-inch pipe to most fixtures; run 3/4-inch pipe to a hose bib or a water heater. Different fixtures place different demands on supply pipes. Each fixture has a demand rating based on fixture units (see chart). These are the flexible lines that run from the stop valve to a faucet, fixture, or appliance.

Where are potable water pipes not to be located?
Potable water service pipes shall not be located in, under or above cesspools, septic tanks, septic tank drainage fields or seepage pits. Where soil or ground water causes contaminated conditions for piping, analysis shall be required in accordance with Section 605.1. 604.1 General.
