What a Proper Dishwasher Connection Actually Involves
Connecting a dishwasher means tying into your sink’s water supply and drain, and critically, installing a high loop or air gap in the drain line to prevent dirty sink water from siphoning back into the dishwasher. Skipping that detail is one of the most common reasons a seemingly fine dishwasher installation causes problems later.
The high loop under your sink isn’t optional, it’s what keeps dirty water from finding its way back into your dishwasher.
When You Need Dishwasher Connection Service
A few common situations call for this service.
- You’re installing a new dishwasher and need it connected to water and drain lines
- Your dishwasher is leaking at the connection point under the sink
- You’re replacing an existing dishwasher and want the connections checked, not just reused
- You’ve noticed the dishwasher isn’t draining properly
- You’re remodeling a kitchen and relocating the dishwasher’s position
What Homeowners Can Handle vs. What to Leave to a Pro
Dishwasher connection is sometimes DIY-attempted, with a few important details to get right.
- Turn off the water supply and power to the dishwasher before starting any work
- Make sure a high loop or air gap is installed in the drain line, this step gets skipped more than it should
- Check that supply line connections are snug but not overtightened, which can crack fittings
- If your sink’s plumbing configuration doesn’t have an obvious connection point, that’s worth having a plumber assess
