Plumbing issues rarely happen at a good time. Here are the most common problems, safe DIY steps, and clear red flags for calling a professional.
Dripping Faucets
Cause: Worn washers, O-rings, or cartridges.
DIY: Turn off water, plug the drain, disassemble handle, replace washer/cartridge, reassemble.
Call a Pro If: Corrosion or seized parts; widespread low pressure suggests bigger supply issues.
Running Toilets
Cause: Faulty flapper, chain length, fill valve.
DIY: Adjust chain, replace flapper, set waterline to marked level.
Call a Pro: Persistent running post-replacement may indicate sediment in the valve or cracked overflow.
Clogged Drains
Cause: Hair, grease, soap scum, foreign objects.
DIY: Plunger, drain snake, enzyme cleaners (avoid harsh chemicals).
Call a Pro: Repeated clogs or multiple fixtures backing up = probable main line issue.
Low Water Pressure
Cause: Aerator blockage, PRV issues, leaks, old galvanized pipes.
DIY: Clean aerators/showerheads, check shutoffs, test multiple fixtures.
Call a Pro: If home-wide pressure is low or fluctuates; possible PRV/main supply or pipe corrosion.
No Hot Water
Cause: Tripped breaker, pilot issue, thermostat, failed heating elements.
DIY: Check breaker, pilot light (gas), reset buttons.
Call a Pro: Leaks, burner problems, tank corrosion, or error codes on tankless units.
Slow Draining Tub/Shower
Cause: Hair + soap buildup in trap.
DIY: Remove stopper, pull debris, snake, enzyme maintenance.
Call Pro: If smell persists or drain remains slow—venting or deeper blockage.
Leaking Pipes
DIY (Temporary): Shut water, use pipe repair clamp/tape, place bucket.
Call a Pro: Permanent repair—fitting replacement, soldering, or PEX coupling.
Sewer Odors
Cause: Dry traps, cracked vents, failed wax ring.
DIY: Run water in rarely used fixtures; replace wax ring if localized to one toilet.
Call a Pro: Persistent odor may mean vent or sewer main problems.
Safety Notes
Kill power to electric water heaters before work.
Never mix tools and live gas lines—call a licensed pro.
Avoid chemical drain cleaners—they can damage pipes and are hazardous.
