Plumbing emergencies can strike without warning — especially in a city like Issaquah, WA, where heavy rainfall, older homes, and shifting soil can all wreak havoc on your pipes. Whether you’re dealing with a flooded bathroom at midnight or a burst pipe on a snowy morning, knowing what to do first can save your home, your money, and your peace of mind.
Here are the Top 10 Plumbing Emergencies Issaquah homeowners face, and what you should do immediately.
1. Burst Pipes
What to do first:
Shut off the main water valve immediately. Then, turn on all faucets to drain the system and reduce pressure. If safe, locate the damaged pipe and contain the leak with towels or a pipe clamp.
📍 Issaquah’s cold winters can increase the risk of frozen pipes bursting. According to Ready.gov, even a small crack can release over 250 gallons of water per day.

2. Clogged or Overflowing Toilets
What to do first:
Use a plunger to try and dislodge the clog. If water keeps rising, turn off the toilet’s shut-off valve (usually behind the toilet near the floor) to prevent flooding.
According to King County Wastewater, flushing non-degradable materials is a common cause of toilet overflows in homes.
3. Sewer Line Backup
What to do first:
Stop using all plumbing fixtures. Look for telltale signs like sewage smells, gurgling drains, or multiple clogs. Avoid exposure to standing sewage due to health risks.
The CDC warns of bacteria, viruses, and parasites in raw sewage that can cause illness.
4. Water Heater Failure (No Hot Water or Leaking Tank)
What to do first:
If leaking, shut off the water heater and water supply to the tank. If there’s no hot water, check the pilot light or breaker. Don’t attempt repairs if you smell gas or see corrosion.
Energy.gov advises regular inspection of water heaters, especially in older homes.

5. Leaking Pipes
What to do first:
Turn off the nearest water valve or the main shut-off valve if needed. Place buckets under the leak and use pipe tape or rubber sheets to minimize dripping.
Even minor leaks can waste up to 10,000 gallons per year per household (EPA) — that’s a high water bill and potential mold risk.
6. Blocked Kitchen Sink Drain
What to do first:
Turn off the garbage disposal. Use a plunger or baking soda + vinegar combo for minor clogs. Never use chemical drain cleaners — they can damage pipes.
Pro tip: Seattle Public Utilities urges residents to keep grease and food scraps out of the drain to prevent clogs.
7. Frozen Pipes
What to do first:
Turn off your home’s water supply. Use a hairdryer to slowly warm the pipe (never a blowtorch). Don’t use water fixtures until thawed and inspected.
The American Red Cross recommends insulating pipes in unheated areas like garages and crawl spaces.
8. Leaking or Malfunctioning Washing Machine Hose
What to do first:
Turn off both the hot and cold water valves. Check for bulges, cracks, or rust around the hose connections. Use a towel to mop up any water.
A burst washing machine hose can release 500 gallons per hour (Insurance Institute for Business & Home Safety) — check your hoses annually.
9. Sudden Drop in Water Pressure
What to do first:
Check if it’s isolated to one faucet or the whole house. Clean aerators and check for leaks. If it’s widespread, it could be a burst pipe, municipal issue, or a pressure regulator failure.
Washington State Department of Health emphasizes the importance of stable pressure to avoid cross-contamination and backflow.
10. Gas Line or Sewer Gas Smell
What to do first:
Evacuate the home immediately if you smell rotten eggs or sulfur — this may indicate a gas leak. Call your utility provider or 911 from outside the home.
Per the U.S. Department of Transportation, natural gas leaks are serious hazards and must never be ignored.
