What to Know About Residential Plumbing Before You Start a Remodel

Planning a kitchen or bathroom remodel? It’s easy to get caught up in the fun parts, tile samples, new fixtures, Pinterest boards, but before any of that can come to life, you need to think about what’s behind the walls: your residential plumbing system. Overlooking plumbing in the early planning stages can lead to unexpected delays, higher costs, and limited options. Here’s what homeowners should know about plumbing before the renovation begins.

1. Understand the Current Layout

Before tearing anything out, take time to understand your existing plumbing system. Ask:

  • Where are the pipes located?
  • Are the water supply lines and drains in good shape?
  • Can they support new fixtures or appliances?

Keeping plumbing in its current location is usually more cost-effective than moving pipes, but if a layout change is part of your vision, it’s best to consult a licensed plumber early.

2. Assess the Condition of Old Pipes

Older homes may have aging pipes that aren’t up to code or could be prone to leaks. If you’re remodeling, now is the perfect time to upgrade outdated residential plumbing components like galvanized steel or polybutylene pipes. Replacing them during a remodel is easier, and often cheaper, than doing it after the new finishes are in place.

3. Plan for Code Compliance

Residential plumbing must meet local building codes and permit requirements. Professional plumbers can help ensure:

  • Proper pipe sizing
  • Correct drain slope
  • Backflow prevention
  • Venting compliance

Skipping permits or ignoring code may cause issues during resale or lead to costly fines.

4. Water Efficiency Upgrades

Remodeling offers the chance to make your plumbing system more efficient. Consider installing:

  • Low-flow toilets and showerheads
  • Tankless water heaters
  • Smart leak detectors

These upgrades can reduce monthly utility bills and are often eligible for rebates or tax incentives.

5. Coordinate Early with Your Plumbing Contractor

Waiting to bring in a plumber until demolition is already underway can slow down the project. Instead, loop them in early so they can:

  • Review the layout
  • Flag potential issues
  • Help coordinate scheduling with other contractors (like electricians or HVAC techs)

Early collaboration saves time and prevents surprises.
