What our Clients think about us
Your satisfaction is our priority.
What Is Dishwasher Water and Drain Line Installation?
This service covers the plumbing side of your dishwasher connection:
Water supply line from the hot water angle stop to the dishwasher
Drain line from the dishwasher to the air gap and/or disposal/drain connection, installed to code
Under-sink configuration adjustments so everything fits and drains properly
It can involve:
Hooking up a brand-new dishwasher in an existing or new location
Replacing old, kinked, or leaking lines on an existing dishwasher
Correcting bad DIY hookups that cause backups into the sink or slow draining
The goal is a safe, leak-free dishwasher hookup that fills, runs, and drains the way it should.
Why Choose Active Plumbing
Dishwasher-specific experience: We handle both water supply and drain lines, not just one side of the install
Drain- and disposal-aware: We make sure your dishwasher ties into the drain/disposal correctly and follows air gap or high-loop requirements
Leak-conscious: We look for existing or potential leaks at angle stops, flex lines, and under-sink connections
Cabinet and floor protection: We pay attention to cabinet floors, toe kicks, and nearby walls for early signs of water damage
Remodel-friendly: Comfortable working with appliance installers, cabinet and countertop pros during kitchen upgrades
Licensed & insured: Nevada License #0047021, trusted for dishwasher line installation in Las Vegas
Immediate Actions (What to Do Now)
Turn off the dishwasher and do not start another cycle if you see leaks, standing water, or error codes
Shut off the hot water angle stop feeding the dishwasher (usually under the sink) if you suspect a supply leak
Avoid running the sink disposal or filling the sink if water is backing up when the dishwasher drains
Move items out from under the sink so we can access the angle stops, drain, and dishwasher connections
Call Active Plumbing at (702) 438-3357 and explain whether you have a leaking dishwasher line, a new dishwasher needing hookup, or recurring drainage issues
Common Dishwasher Line Problems We See
Water leaking under the sink or from the dishwasher kick plate
Standing water in the bottom of the dishwasher after a cycle
Sink backing up when the dishwasher drains
Old copper or plastic supply lines that corrode, crack, or kink
Drain lines installed without a high loop or air gap, causing odor or backflow
Angle stops that won’t fully shut off or leak when the dishwasher is running
“New” dishwasher installs where the plumbing connections were never done correctly
If you’re mopping under the dishwasher, smelling musty odors near the sink, or avoiding running cycles, it’s time to address the plumbing.
Call & Situation Review
You call (702) 438-3357 and tell us if you have a new dishwasher to hook up, an existing unit with leaks or drain issues, or both. We schedule a visit with access to the kitchen and under-sink area.
On-Site Inspection & Layout Check
Your plumber inspects the under-sink plumbing, angle stops, existing supply and drain lines, and dishwasher location, and checks how the dishwasher connects (or should connect) to the disposal or drain and air gap/high loop.
Plan & Pricing for Water and Drain Connections
We explain what’s needed: new supply line, new drain line, air gap or high-loop correction, valve replacement, or full re-route. You’ll get clear, upfront pricing before we start work.
Water Supply Line Installation or Replacement
We shut off water, replace or install the hot water angle stop if needed, and run a proper, flexible, dishwasher-rated supply line from the valve to the dishwasher, securing connections at both ends.
Drain Line Installation, Routing & Connection
We install or replace the dishwasher drain line, set a proper high loop or connect to an air gap (per code and sink setup), and tie into the disposal or sink drain using appropriate fittings to prevent backflow and leaks.
Testing, Leak Check & Cleanup
We restore water, run a test cycle or fill/drain test (as allowed by the appliance), and check for leaks at angle stops, supply, drain, and under the dishwasher. After confirming proper draining and no leaks, we clean up the work area and explain what we did and what to watch for.
What’s Included
Inspection of existing plumbing under the sink and at the dishwasher location
Assessment and explanation of required water and drain line work
Installation or replacement of dishwasher water supply line and related angle stop (if scoped)
Installation or correction of dishwasher drain line, including high loop/air gap and disposal/drain connections
Testing for proper fill and drain operation and leak checks at all connections we work on
Written notes and recommendations for any additional plumbing or cabinet/floor repairs needed
Costs & Timelines (What to Expect)
Many dishwasher line installations and corrections can be completed in a single visit, especially for standard under-sink setups
You receive upfront, itemized pricing after we inspect the plumbing layout, condition of valves, and dishwasher location
Main cost factors include line replacement vs. new run, valve condition, need for new air gap or high loop adjustments, and complexity of access and routing
Every job includes a line-item estimate separating diagnostic, supply line work, drain line work, angle stop changes, and any optional upgrades
Insurance & Claims Help
Dishwasher leaks can cause significant hidden cabinet and floor damage:
We can document failed lines, valves, or drain setups that contributed to water damage
Our detailed invoices help explain the plumbing cause to insurance or home warranty providers if you pursue a claim
(Coverage and claim decisions always depend on your specific insurer and policy; this is not financial or legal advice.)
Risks of Waiting (Why Act Now)
Cabinet and floor damage: Slow leaks under dishwashers or sinks can rot cabinet floors and ruin flooring
Mold and musty odors: Warm, damp spaces near dishwashers are ideal for musty smells and potential mold growth
Backups and overflows: Bad drain connections can push dirty water back into your sink or dishwasher
Appliance issues: A poorly supplied or drained dishwasher can strain pumps and shorten appliance life
Hidden costs later: Ignoring small drips or slow drains now often means bigger cabinet and flooring repairs down the road
Methods, Materials & Quality Standards
Dishwasher-rated materials: We use proper flex supply lines, drain hoses, and fittings suitable for dishwasher use
Code-compliant drain setup: We configure air gaps or high loops and disposal/drain connections to local code
Secure connections: All fittings and clamps are tightened and tested—no loosely slipped-on hoses
Angle stop and valve awareness: We evaluate and often recommend upgrading old valves for safer shutoffs
Thorough testing: We don’t just “hook it up”—we test fill and drain, watching carefully for leaks or backups
Frequently Asked Questions
Do appliance installers hook up the plumbing too?
Sometimes—but many installs are limited and don’t address faulty valves, old lines, or bad drain setups. We focus on the plumbing quality and code compliance behind the appliance.
Can you install my new dishwasher and hook up lines in one visit?
We handle the plumbing side—some homeowners have the appliance set in place first, others coordinate timing so we’re there when it’s delivered. We’ll work with you on timing.
I’m getting water in the bottom of my dishwasher after a cycle. Is it a line issue?
It could be a drain line configuration or blockage, or an internal appliance issue. We can check the drain, high loop/air gap, and under-sink connections and help you determine whether a plumber or appliance tech is needed.
Can you move my dishwasher to a different location?
Often this involves additional water and drain line work, and sometimes cabinet modifications. We’ll evaluate the layout and explain what’s involved.
Do you only work on kitchen dishwashers?
Yes—this service is focused on standard residential kitchen dishwashers and their water and drain connections.
Do you offer dishwasher water and drain line installation near me in Las Vegas?
If you’re in Las Vegas, Henderson, North Las Vegas, Summerlin, or nearby communities, yes—Active Plumbing can install, replace, or correct dishwasher water and drain lines.
