    Hay OR, the kitchen sink may be or not grounded. That all depends on the type of piping being used. NEVER ground electric to a sink or any thing else that has water in it; BAD IDEA. I know people do it, but it is not very bite to do!

    Kitchen sink?  No.  Outlets are about all you can count on in a house built in the last 20 or more years.  Why are you looking for something grounded?

    The waterlines these days are generally plastic as are the sink and tub drains. The electrical appliance shocking you to death by submersion, is practically impossible with GFCI outlets placed anywhere there is water. No the kitchen sink, even stainless steel, is not grounded. The circuit breaker box is grounded by copper clad stakes, whose number and depth are determined by soil conditions.

    Only way you sink is grounded is if your supply water pipe is copper from outside to the faucet. Course you faucet would be grounded there not your sink. If your drain pipe was metal from sink to the outside which hasn't been done since the 60's maybe up into the early 70's.  

    Only thing in your house thats gonna have earth ground is electrical sometimes the satellite guy will tie into the earth ground.

    No, not unless it has some kind of faucet that turns on when you touch it.  If you have copper pipes they will be grounded where they enter the house.

    dtstellwagon IS the trol he warns against.

    Metal plumbing IS NOT required to be connected to electrical systems and when grounded, is grounded by ACTUAL contact with the ground.

    IN addition, he is DEAD wrong, with the emphasis on DEAD that pure water doesn't conduct electricity AND that it doesn't exist.

    You may note he NEVER cites a source when he claims what everyone knows is wrong.

    There is NO REASON to ground the kitchen sink as not all kitchen sinks are metal. Some are fiberglass, some granite, some are part of the molded counter plastic.

    A ground wire should be fitted to ALL sinks, taps/faucets and baths. This ground wire should be run directly to the electrical breaker box. This must be a 4mm cable to carry a fault current to ground and thus cause the fuse/breaker to trip within 2ms. YOU ARE NOT THE PATH TO GROUND. If a fault occurs and the ground wire is NOT connected, then you will be killed, because you will be the nearest path to ground.

    It takes just 10mA to stop your heart. GOT THAT?  DO NOT LISTEN TO THESE OTHER FOOLS AND IDIOTS HERE. If ever you smell gas, NEVER SWITCH 'ON' or 'OFF' THE LIGHT or use THE PHONE. The spark across the switch contacts will IGNITE THE GAS.

    Call from a public call box or a neighbor's phone

      Electrical engineer?  Maybe. but t you know nothing about houses.built in the last 30 years. Sinks are often plastic / composite or stone.  Fresh and waste water pipes are commonly some form or plastic.  Test for ground at electrical outlets and assume NOTHING ELSE IN THE HOUSE is grounded.

    There is no reason to ground a kitchen sink. Also not possible if there is some plastic drain pipe under the sink. MAYBE the incoming power is grounded, and MAYBE a metal pipe for incoming natural gas is grounded (to eliminate sparking), but I confess idk for sure.

      People here give advice every day that could kill someone, but it's not a violation of the Y!A rules to be criminally ignorant.

    you can not rely on anything other than a proper electrical ground. some older houses did have all copper/brass piping in which the cold water line ran underground .... these would test as grounded. More modern houses may have non-conductive water lines and pvc [non-conductive sewer lines in which case the kitchen sink is NOT grounded
