9 Signs it's Time to Call a Wauwatosa Plumber
Knowing when to call a plumber helps you avoid water damage, plumbing emergencies, and costly repairs. Here are some signs it's time to call Knight Plumbing:
- Persistent and severe clogs: If you have stubborn clogs in sinks, toilets, or drains that don't clear with regular methods, call a plumber to inspect the issue.
- Low water pressure: A sudden drop in water pressure can indicate leaks, pipe blockages, or a water main concern. Our plumbers have the tools to quickly identify and resolve the issue.
- Leaking pipes: Water leaks waste water, cause property damage, and lead to mold. If you notice water spots, stains, or dripping sounds, schedule a plumbing service as soon as possible.
- Burst pipes: If a pipe bursts in your home, turn off the water supply and call right away to prevent more damage.
- Strange odors: Bad smells from drains or sewage backups can point to system issues. Address these promptly with a plumber’s help.
- Gurgling sounds: Unusual noises from plumbing fixtures or pipes often signal air or water flow problems that need inspection and repair.
- Water heater issues: If your water heater makes noises, releases discolored water, or won’t provide consistent hot water, have a plumber take a look at the system.
- Running toilets: A toilet that keeps running wastes water and can raise your utility bill. Our plumbing team can diagnose and resolve this issue.
- Frozen pipes: In winter, frozen pipes are a real concern in Wauwatosa. If you think your pipes froze or burst, contact a plumber right away.
Minor leaks or slow drains might not seem urgent, but in Wauwatosa’s older neighborhoods, these small issues can signal deeper trouble in aging underground pipes. Our team has years of experience solving challenges unique to historic homes, such as pipe corrosion and hard-to-reach access points. We routinely help local residents deal with problems caused by tree roots, heavy soil, and freeze-thaw cycles, which affect shut-off valves and sump pump performance. Having a trusted local plumber means you receive solutions tailored to your home, not just a basic one-size-fits-all fix.
While you may be able to fix some minor problems yourself, if you are unsure of the solution, always call a licensed plumber to prevent the issue from getting worse.
Our Wauwatosa plumbing services are often available on a same-day basis. To request an appointment, call (414) 420-0625 now!
