Appliance store says I need a shutoff valve behind the refrigerator. They want a valve box in the wall to attach their flexible water line. The plumber put in flexible copper tubing with the shutoff valve under the sink. Appliance store says that's against code. I live in California if that makes a difference. The copper tubing is the smooth type. The refrigerator is a LG French door.

    Ask the appliance people to quote chapter and verse of the code they're referring to. Then remind them that you'll do the install yourself if they don't cooperate. (Even if they are somehow correct, and I give that very slim odds, your plumber did the smart thing.) – Aloysius Defenestrate Apr 29 '15 at 20:42
  • Just to be sure... is your copper of the smooth walled type, or is it corrugated? (If corrugated, you're limited to 10', per California Plumbing Code 604.12.) – Aloysius Defenestrate Apr 29 '15 at 23:40
  • What is the make and model refrigerator? What does it say in the manufacturers installation instructions? – Tester101 Apr 30 '15 at 10:01

The guy at the appliance store is correct. California plumbing code 606.5 states

A control valve shall be installed immediately ahead of each water-supplied appliance and immediately ahead of each slip joint or appliance supply.

  • Yes, but it does not say that it must be right AT the refrigerator. If you read the PURPOSE of the change from the 2012 code, it was because people were putting valves in attic spaces, not accessible to the homeowner if the appliance or fitting developed a leak. The valve under the sink in the same kitchen would meet that code requirement, so long as there were no other fittings or tap-offs between that valve and the ice maker. I've done that and had it pass many times. That said, I RECOMMEND putting it behind the fridge so that it's easier to turn it off if you have to pull the fridge out. – J. Raefield Jul 10 '18 at 1:14
