What does drain installation involve?

Drain installation typically includes evaluating the plumbing layout, choosing the right materials, setting proper slope and venting, connecting the new pipe to existing plumbing, and testing the system for flow and leaks. At Professional Plumbing LLC, we follow Washington State plumbing codes to ensure long-lasting, reliable drainage.

Why Proper Drain Installation Matters in Lynnwood

Lynnwood is filled with a mix of older homes and newer builds — which means drain systems vary widely. Some homeowners still rely on aging cast iron or galvanized steel pipes, while others already have more modern PVC or ABS lines. Each type requires a different installation approach.

When drains aren’t installed correctly, it can lead to unnecessary trouble such as:

• Slow or sluggish drainage
  
• Sewage smells
  
• Persistent clogs
  
• Water damage behind walls or under floors
  
• Long-term structural issues
  

Good drainage isn’t just convenient — it protects your home. Our team understands how to design and install drains that meet local codes, flow properly, and stand up to daily use.

Common Signs You May Need a New Drain Installed

Most homeowners contact us because they’ve noticed problems that keep coming back, no matter how many times they’ve tried to fix them.

Here are some of the most common signs:

Slow or gurgling drains

This often points to venting issues, poor slope, or pipe deterioration.

Frequent backups

If clogs return even after clearing, the drain line may be incorrectly installed or damaged.

Standing water or leaks under sinks

Worn drain traps and loose fittings may need to be replaced entirely.

Home remodels or additions.

Any new bathroom, kitchen, or laundry setup needs proper drain installation for everything to work correctly.

Bad odors coming from drains

Often a sign of improper venting or failing under-sink plumbing.

If any of these sound familiar, we can inspect your system and help you decide the best next steps.

Key Factors That Impact Drain Installation 

Choosing the right materials and design is crucial for proper drainage. Here are the main components we walk homeowners through:

ABS vs. PVC Drain Lines

Both are durable and commonly used. We help you pick the one that works best for your home and meets local code requirements.

Replacing Old Cast Iron Drains

Older Lynnwood homes often have cast iron piping that corrodes over time, reducing flow and causing leaks.

Proper Drain Slope

Even a small mistake in slope can lead to standing water or frequent blockages. Correct grading ensures smooth, consistent drainage.

Venting Requirements

Without proper venting, drains can gurgle, smell, or clog easily. Our installations are always fully vented for long-term reliability.

How We Install Drains — Our Step-by-Step Process

Every home is different, so we tailor our installation approach to your specific layout. Here’s what the process looks like:

1. We assess the space

We review your current plumbing, check for damage, identify restrictions, and map out what needs to be installed or replaced.

2. We design the drainage layout

This includes slope, venting, pipe size, tie-ins, and fixture locations. Planning is the key to a long-lasting system.

3. We choose the right materials

We make recommendations based on your home’s structure, code requirements, and long-term durability.

4. We install the drain lines

Our plumbers work carefully to ensure proper pitch, smooth connections, and secure fittings.

5. We test the system thoroughly

Before we finish, we perform pressure testing and flow testing to make sure everything works exactly as it should.

6. We review everything with you

We explain what was installed, how it works, and any tips to keep your drainage system performing well.

Maintenance After Installation

A new drain line is an investment — and like any part of your plumbing, it benefits from regular maintenance.
If you ever run into slow drains or buildup, our Drain Cleaning service is always available to keep your system flowing smoothly.
