You’ve just bought a new washing machine—or maybe you’re moving into a new place—and now you’re wondering: “Do you need a plumber to install a washing machine?” It’s a smart question. While many assume it’s a simple plug-and-play task, improper installation can lead to leaks, water damage, or even voided warranties. The good news? You might not need a plumber—but it depends on your setup, skills, and local codes. Let’s break it down so you can decide with confidence.
What’s Involved in Washing Machine Installation?
Before deciding whether to DIY or hire a pro, understand what the job actually entails. Installing a washing machine typically involves:
Connecting to a cold water supply line (some models also use hot water)
Attaching the drain hose to a standpipe or utility sink
Ensuring the unit is level and stable
Plugging into a dedicated electrical outlet (usually 120V in the U.S.)
Checking for leaks and proper drainage
According to the U.S. Department of Housing and Urban Development (HUD), over 14,000 home insurance claims annually are linked to washing machine hose failures—many stemming from poor installation.
Can You Install a Washing Machine Yourself?
Yes—in many cases, you can. If you’re replacing an old unit in the same location and the plumbing/electrical setup is already in place, a DIY installation is often straightforward.
✅ When DIY Is Safe & Smart:
You have existing shut-off valves for hot/cold water
The drain pipe is properly vented and within reach
Your floor is level and sturdy
You’re comfortable using basic tools (wrench, level, tape measure)
🛠️ Basic DIY Steps:
Turn off water supply and unplug the old machine (if applicable).
Connect inlet hoses to the machine and water valves (hand-tighten, then ¼ turn with a wrench).
Route the drain hose into the standpipe (keep it 30–36 inches above floor level per plumbing codes).
Level the machine using adjustable feet—use a bubble level.
Run a test cycle and check for leaks at all connections.
💡 Pro Tip: Use stainless steel braided hoses instead of rubber—they last longer and reduce burst risk. The International Association of Certified Home Inspectors recommends replacing hoses every 5 years.
When Should You Hire a Plumber?
While DIY works for many, certain situations absolutely require a licensed plumber:
🚨 Red Flags That Demand a Pro:
No existing plumbing (e.g., converting a closet into a laundry room)
Old or corroded pipes that need replacement
Improper drain setup (e.g., no P-trap or vent—required by plumbing codes )
Local regulations requiring permits or inspections (common in NYC, Chicago, and parts of California)
Gas-powered dryers nearby (if installing a combo unit or shared utility space)
A 2023 study by HomeAdvisor found that 68% of homeowners who attempted complex plumbing without experience ended up paying more due to water damage or rework.
“If you’re cutting into walls, rerouting pipes, or unsure about venting, don’t gamble,” says Maria Lopez, a licensed plumber with 15 years of experience in Austin, TX. “A $150 service call beats a $3,000 insurance deductible.”
DIY vs. Hiring a Plumber: Pros and Cons
Cost
$0–$50 (hoses, tools)
$100–$300+
Time
30–90 minutes
Same-day service
Risk
Leaks, voided warranty
Minimal (licensed pros carry insurance)
Skill Needed
Basic handyman skills
None
Warranty
May be voided if not installed per manual
Often covered under pro’s workmanship guarantee
Bottom line: If your laundry area is “move-in ready,” DIY is fine. If you’re building from scratch or see rust, leaks, or odd pipe configurations—call a plumber.
Common Mistakes to Avoid
Even experienced DIYers slip up. Here are the top errors—and how to dodge them:
Ignoring the drain height → Siphoning or poor drainage. Keep hose 30–36” high.
Skipping the leveling step → Machine “walks” during spin cycle. Use a level and adjust feet.
Using old rubber hoses → Prone to bursting. Upgrade to stainless steel.
Plugging into an extension cord → Fire hazard. Use a grounded, dedicated outlet.
Step-by-Step Guide: Installing Your Washing Machine (DIY)
Follow these steps carefully:
Prepare the space: Clear area, check floor stability.
Install new hoses (if needed): Attach to machine’s inlet valves (mark hot/cold).
Connect to water supply: Match hoses to shut-off valves. Turn valves on slowly.
Position drain hose: Insert into standpipe; secure with clip (don’t seal airtight—vents need airflow).
Level the unit: Place level on top; adjust front feet until bubble is centered.
Plug in: Use a 3-prong grounded outlet—no adapters.
Test: Run a short cycle. Check connections every 5 minutes for first 15 minutes.
⚠️ Never leave a first-time test unattended. Most leaks appear within minutes.
FAQ Section
Q1: How much does it cost to hire a plumber to install a washing machine?
Most plumbers charge $100–$250 for a standard install if plumbing is already in place. Complex jobs (new lines, permits) can cost $400+.
Q2: Can I install a washing machine without a plumber if I’ve never done it before?
Yes—if you’re replacing an old unit in the same spot and follow instructions carefully. Watch a tutorial, read your manual, and take your time.
Q3: Does installing a washing machine require a permit?
In most U.S. cities, no permit is needed for replacement. But if you’re adding new plumbing lines or changing room layout, check with your local building department.
Q5: Will my warranty be voided if I install it myself?
Not necessarily. Most manufacturers (like Whirlpool, LG, Samsung) allow DIY installs as long as you follow their guidelines. Keep your manual and installation photos as proof.
So, do you need a plumber to install a washing machine?Not always—but sometimes, absolutely. If your laundry room is already plumbed and you’re comfortable with basic tools, DIY can save you money and give you peace of mind. But if you’re dealing with new construction, old pipes, or local code requirements, a licensed plumber is worth every penny.
Don’t risk a flooded basement over a $200 service call. Assess your situation honestly, prioritize safety, and when in doubt—call a pro.
