Seattle’s iconic rain, aging infrastructure, and booming housing market all add up to one inevitable reality: plumbing problems. Whether you’re a longtime homeowner in Capitol Hill or a new condo resident in South Lake Union, plumbing issues will arise—and when they do, knowing when to call in the pros can save you thousands in damage and stress.
If you’re unsure whether it’s time to pick up the phone, here are the top 10 signs you need a professional plumber in Seattle—courtesy of Angi’s expert guide, plus insights from our team at Einstein Pros Seattle.
1. Low Water Pressure Throughout the House
If you’re experiencing weak water flow in multiple faucets, it’s likely not a one-fixture issue. This could signal:
- A hidden leak
- Corroded pipes
- A failing pressure regulator
In Seattle, older homes—especially pre-1960s builds—often suffer from deteriorated galvanized pipes. Don’t ignore it. A professional plumbing inspection can pinpoint the source and prevent more expensive repairs later.
2. Persistent Clogs in Sinks or Tubs
A slow-draining sink may seem like a minor nuisance, but if it keeps coming back, you might be facing a deep blockage or even tree roots in your sewer line—common in Seattle’s tree-lined neighborhoods. If plungers and store-bought drain cleaners don’t cut it, it’s time to call in the pros for a drain cleaning service.
3. Gurgling or Bubbling Drains
Notice strange noises from your toilet or sink after using water elsewhere in the house? This could be a sign of venting issues or partial blockages in your plumbing system.
Gurgling drains often point to air being trapped in your pipes, which is a red flag that water isn’t flowing freely. A licensed Seattle plumber can diagnose this with a camera inspection.
4. Water Stains or Damage on Walls/Ceilings
Seattle’s wet weather already increases your home’s risk of moisture issues. But if you spot unexplained stains or bubbling paint on your walls or ceilings—especially under bathrooms or kitchens—it could be a hidden leak.
Addressing this fast is critical to prevent:
- Mold growth
- Structural damage
- Increased utility bills
Don’t DIY—call a Seattle leak detection specialist.
5. No Hot Water or Inconsistent Temperatures
Inconsistent or non-existent hot water is usually a sign that your water heater is on the fritz. In Seattle, hard water buildup is a common culprit. Whether you have a traditional or tankless system, you may need a:
- Sediment flush
- Thermostat repair
- Full unit replacement

6. Visible Pipe Corrosion or Rust
Open up your cabinets and check your visible plumbing. If you see:
- Blue/green corrosion
- Rust
- Flaking metal
…your pipes may be compromised. Seattle homes with copper or galvanized steel piping are especially at risk. Call a pro to evaluate and plan a repipe before things get worse.
7. Running Toilet That Won’t Stop
While a running toilet may seem like a small annoyance, it can waste up to 200 gallons of water per day, according to the EPA WaterSense Program.
This usually means a faulty flapper, fill valve, or overflow tube—easy fixes for a Seattle plumbing professional, and a quick way to lower your water bill.
8. Foul Odors from Drains or Pipes
A sewer smell in your home is never normal. It might mean:
- A dried-out P-trap
- Sewer line break
- Vent pipe blockage
Seattle’s older neighborhoods are especially prone to failing sewer systems. If the smell is persistent, don’t delay—schedule a sewer inspection and repair.
9. Backed-Up Sewer Line
A slow-draining toilet, multiple clogs, or wastewater coming back up through drains can signal a mainline sewer backup—a serious and potentially hazardous issue.
This is an emergency. Call our 24/7 emergency plumbing services immediately if this happens.
10. Water Meter Is Running When All Fixtures Are Off
If your water meter spins when no water is being used, it’s a strong indicator of a hidden leak, possibly underground or within your walls. Seattle’s combination of clay soil and heavy rainfall can exacerbate hidden leaks, leading to water damage and foundation issues.
We recommend a comprehensive plumbing leak audit to find the source and fix it fast.
