Phase 1: Ensure Safety And Locate The Drain Hoses

  • Compared with other plumbing projects, attaching drain lines is quite safe. But attend to your safety first and turn off the line of your Dishwashers and other adjacent appliances.
  • Secondly, turn off the supply valve.
  • Now locate the drain pipes you want to connect. They are usually channeled through cabinets. If you need to move the washer to get to the hose, remember to disconnect the wires and strain relief nuts inside the junction box.
  • Spread towel under the drain lines.
  • Take note of the diameter of each, although, the drain hose pipes are usually of universal size. Next, bring the two drain hose ends together and verify if they can touch each other without any extension.
  • If they touch, proceed to the next section.
  • If they don’t, extend the comparatively smaller drain duct.
  • To extend the drain hose, attach the clamp and then insert the dishwasher drain hose coupler at the end of the smaller drainpipe.
  • Then, wear the clamp again to the extension pipe and enter it into the open end of the connector.
  • Tighten each clamp with a screwdriver and measure stress by mildly pulling the extension. Great, off to the next section now.

Phase 2: Connect The Drain Hoses

  • Now that the drain hoses are within reach of one another Put clamps on their mouth.
  • At the same time, put another clamp on the extension pipe too.
  • Afterward, join the top branches of the Y connector with the drain pipes. Insert them far enough to snug the connection.
  • Later, couple the bottom of the Y connector with the extension pipe, insert enough to make the connection tight.
  • Consolidate the links tightening each clamp with a screwdriver.
  • Feed the extension through the drain hole.
  • Reposition the dishwasher if you had to move it and reconnect the wires in the junction box.

Phase 3: Check The Connections

  • Now that everything is arranged and the fittings are seemingly rigid and safe, switch on the dishwasher and adjacent appliances.
  • After that, turn on the water supply valve and activate the drain.
  • Observe closely for any leakage. There shouldn’t be any, considering you’ve introduced right-sized connectors.
  • However, if there is any leakage in the connections, using an additional rubber clamp over the connection will take care of it.
  • That’s it, you’re done. Pat yourself on the back.
