Is a washing machine drain hose required to be secured at the standpipe?

Sunday, June 17, 2018

 The Residential Edition of the Florida Building Code (FBC) and the International Residential Code (IRC) do not address washing machine drain hose attachment. But manufacturer’s installation instructions are specific about requiring that the drain hose be secured, to avoid it jumping out of the standpipe at a surge of pressure in the beginning of the drain cycle of the machine, and flooding the floor. Many manufacturers provide securing devices in the bag of installation supplies. The simplest solution is shown below, securing the drain hose with a zip-tie to one of the fill hoses at a washing machine faucet box, and an example of an unsecured hose simply stuck into the standpipe is shown above.

     The diagram below, from a GE installation manual, also shows recommended ways to secure the hose to the side of a standpipe that is not in a washing machine faucet box at #2, and how to secure the hose with a high loop when the standpipe is below 30-inches above the floor at #3—to avoid creating a vacuum that siphons the water out of the machine.
