Plumbing questions
Plumbing issues can interrupt daily routines without warning. Homeowners contact us about slow drains, inconsistent water temperature, and visible leaks. This guide shares the checks our technicians perform and safe homeowner steps that may help identify the source.
Anything not covered here, ask Number One Plumber of Charlotte directly on (888) 205-8601.
Water heater problems
Why does my water heater make popping sounds?
Sediment settles at the tank bottom and traps steam bubbles that pop when the burner fires. Our technicians drain the tank through the bottom valve to remove the buildup. Check the temperature dial setting first and listen for the sound near the burner area only. The dip tube may also break and stir up debris.
What causes no hot water after the power stays on?
A failed upper heating element stops heat from reaching the top half of the tank. Our technicians test each element with a multimeter after shutting off power. Homeowners can verify the breaker has not tripped and confirm the pilot stays lit on gas models. Thermostat failure also cuts power to the elements.
How do I check for a leaking water heater?
Look for moisture around the top connections and at the drain valve first. Our technicians inspect the temperature and pressure relief valve discharge pipe for signs of discharge. Rust streaks on the outer jacket often indicate internal tank corrosion that requires full replacement. Never block the relief valve outlet.
When should the anode rod get checked?
The rod protects the tank lining from corrosion and needs inspection every few years. Our technicians remove the hex head and measure remaining material thickness. Thin or pitted rods get replaced with magnesium or aluminum versions depending on local water chemistry. This step extends tank life before repiping becomes necessary.
Drain and sewer line questions
What causes a slow kitchen sink drain?
Grease and food particles build up inside the trap and branch line. Our technicians run a cable through the cleanout to break the restriction. Homeowners can remove the trap and clear visible debris with a wire hook but should avoid chemical cleaners that damage pipes. A partial clog often sits past the trap.
Why does the main sewer line back up into the basement?
Tree roots enter joints or a pipe collapses and blocks flow. Our technicians locate the cleanout and run a camera to identify the exact spot. Homeowners should stop running water and avoid flushing until the line clears. Vent stack issues can also create negative pressure that pulls waste backward.
How do I tell if the clog sits in the trap or farther down?
Fill the sink and watch how fast it empties after the stopper lifts. Our technicians test by running a hand auger through the trap first. If water still backs up after the trap clears, the branch or main line holds the restriction. Multiple fixtures affected at once point to a deeper sewer problem.
What happens during a sewer camera inspection?
A flexible camera head travels the line and sends video to a monitor above ground. Our technicians note root intrusion, offset joints, and standing water that shows the slope has failed. The recording helps decide between spot repair and full sewer line replacement without digging blind trenches.
Leak and fixture repairs
How do I find a hidden pipe leak under the floor?
Warm spots on flooring or ceiling stains below bathrooms often mark the path. Our technicians use moisture meters and pressure tests on isolated sections. Homeowners can shut off the main valve and watch the meter for continued movement that confirms an active leak. Slab leaks require different tracing tools.
Why does the toilet keep running after flushing?
The flapper fails to seal or the fill valve float sits too high. Our technicians replace the flapper first and adjust the float arm or chain length. Homeowners can remove the tank lid and listen for water entering the overflow tube. A worn flush valve seat also allows continuous seepage.
What causes low water pressure at one faucet only?
Mineral buildup restricts the aerator screen or cartridge inside the handle. Our technicians remove the aerator and clean the screen or replace the cartridge. Check the shutoff valve under the sink first to confirm it opens fully. Supply line kinks behind the wall also reduce flow to that fixture alone.
When does a leak require repiping a section of wall?
Repeated pinhole leaks in copper or corrosion on galvanized lines indicate the pipe has reached the end of service life. Our technicians isolate the damaged run and install new PEX or copper through access panels. Homeowners can monitor for damp drywall and must shut off water if pressure drops suddenly.
