Seattle homeowners are often independent and resourceful—traits that can come in handy when handling minor plumbing repairs. But not all plumbing issues are DIY-friendly. In fact, some jobs, when tackled without proper training or licensing, can lead to costly damage, code violations, or even health hazards.
In this post, we’ll break down when it’s safe to tackle a plumbing issue yourself, and when it’s time to call in a licensed professional plumber in Seattle, like the experts at Einstein Pros Seattle.
✅ DIY Plumbing Tasks You Can Handle
Some plumbing jobs are low-risk and manageable with basic tools and a bit of research. These include:
1. Unclogging Drains
Simple clogs in sinks or tubs are often caused by hair, food particles, or soap scum. You can try:
- A plunger
- A drain snake (auger)
- A mixture of baking soda and vinegar
Avoid chemical drain cleaners, which can damage your pipes and are discouraged by the Washington State Department of Ecology.
2. Replacing Showerheads or Faucets
Most modern fixtures are designed for easy installation. Just make sure to turn off the water supply first.
3. Fixing a Running Toilet
Replacing the flapper, fill valve, or float can often solve this common problem.
4. Installing a New Dishwasher or Washing Machine
If you’re simply hooking up to existing lines, most homeowners can handle this with some guidance from the manufacturer’s instructions.
⚠️ Plumbing Problems That Require a Licensed Plumber
Washington state law requires licensed plumbers for specific plumbing tasks, particularly those that affect drinking water, drainage, or gas systems. Here’s when you should call Einstein Pros Seattle:
1. Burst or Leaking Pipes
Leaking pipes can cause water damage, mold, and even structural issues. A licensed plumber can:
- Diagnose the cause of the leak
- Replace corroded or frozen sections
- Prevent future damage with proper repairs
2. Water Heater Installation or Repair
Water heaters involve both plumbing and (often) electrical or gas components. Improper installation can:
- Void your warranty
- Lead to scalding, leaks, or fire risks
- Violate Seattle plumbing code
3. Major Sewer or Drain Line Blockages
Slow drains throughout your home or backups in your basement? These often signal a main line issue, which requires:
- Sewer camera inspection
- Professional hydro-jetting
- Permits for repairs under Seattle code
4. New Plumbing Installations or Remodels
Whether you’re adding a bathroom, moving kitchen fixtures, or upgrading an old home, local building codes must be followed. Licensed plumbers ensure:
- Work passes inspection
- Permits are pulled
- Pipes meet Seattle’s Uniform Plumbing Code
You can verify a plumber’s license with the Washington State Department of Labor & Industries.
5. Backflow Prevention Devices
Seattle requires backflow devices in certain situations to prevent contaminated water from entering the public water supply. These installations and annual tests must be handled by certified professionals.
Why Licensing Matters in Seattle
Seattle’s plumbing code is designed to protect both public health and environmental safety. A licensed plumber:
- Undergoes state-approved training and certification
- Is insured and bonded
- Knows how to meet Seattle Public Utilities and Washington state plumbing regulations
Attempting unlicensed plumbing work can result in:
- Code violations
- Fines
- Insurance claim denials in the event of water damage
