Replacing a water line is no small task—but hiring a professional ensures the job is done right the first time. While some homeowners may wonder, “Can I replace the water line myself?”, the real question is whether it’s worth the risk. With over 50 years of plumbing experience, BEST Plumbing and Drainage Contractors delivers expert water line replacement services that prioritize safety, compliance, and long-term performance. In this article, we explore why going pro is the smart choice—and how it can save you time, money, and headaches down the road.
What Does Water Line Replacement Involve?
Your home’s main water line delivers fresh, pressurized water directly from the municipal supply. When that line fails—due to corrosion, cracks, tree roots, or shifting soil—you may experience leaks, low water pressure, or total service loss.
Replacing a water line requires:
Locating and exposing the old pipe (often buried several feet underground)
Cutting and removing damaged sections
Choosing proper materials (copper, PEX, or HDPE)
Installing new lines with secure, code-compliant connections
Backfilling and restoring the site
Coordinating inspections and permits
It’s a major undertaking with no room for error.

Why DIY Water Line Replacement Is Risky
You Could Violate Local Plumbing Codes
Most municipalities have strict plumbing regulations. DIY attempts often fail to meet those standards. Improper work may lead to fines, denied permits, or insurance claims being denied during a future issue.
You Risk Hitting Underground Utilities
In Ontario, homeowners must call Ontario One Call before digging. But even with a utility locate, DIYers may misread the maps or damage gas, cable, or sewer lines. These errors are dangerous—and expensive.
Incorrect Materials or Connections Can Lead to Leaks
Not all piping is equal. DIY replacements may use low-grade materials or incorrect fittings. This leads to joint failure, contamination risks, or corrosion—issues that a licensed plumber can easily prevent.
Health Risks Are Real
Old water lines may contain lead or other contaminants. Disturbing them without safety measures could expose you to harmful materials. In older homes, asbestos may also be present near utility entry points.
You Could Spend More Fixing Mistakes
What seems like a cost-saving move often becomes a costly redo. By the time repairs and code corrections are made, DIY projects can exceed professional quotes.

How to Choose the Right Contractor
Not all plumbing companies are the same. When selecting a contractor, consider the following:
Years of experience: Look for a company with a long-standing reputation.

Licensing and insurance: Always verify credentials.
Warranties: Ask what’s covered and for how long.
