Leak and Repair Questions
What causes a persistent drip from a faucet?
A worn washer or cartridge inside the handle usually allows water to seep past the seat. Our technicians remove the handle, inspect the seat for scoring, and replace the cartridge if the seal has hardened. Homeowners can shut off the angle stop under the sink and avoid forcing the handle until service arrives.
How do technicians locate a hidden wall leak?
They check moisture meters on adjacent drywall, listen for running water with a stethoscope at valves, and examine ceiling stains below. Once the supply line is isolated, pressure is observed on the gauge. Homeowners can note which fixtures lose pressure and avoid using those outlets.
What should be done if a supply line bursts at night?
Locate and close the main shutoff valve at the meter or where the line enters the building. Place towels or a bucket under the wet area to limit floor damage. Leave cabinet doors open for air circulation and do not attempt to patch pressurized copper or PEX until our technicians arrive.
Why does a leak appear only after the dishwasher runs?
The high-pressure discharge hose or the door gasket may have developed a crack that opens under load. Technicians test the drain hose for kinks and check the air gap fitting. Homeowners can run a short cycle with the dishwasher empty and note the exact minute the water appears.
Water Heater and Toilet Questions
Why does the water heater produce rusty or discolored water?
Sediment and anode rod corrosion collect at the bottom and stir when hot water demand increases. Technicians drain several gallons from the tank, inspect the dip tube, and check the anode condition. Homeowners can avoid running hot water for laundry until the tank is flushed.
What makes a toilet run continuously after flushing?
The flapper may not seat fully or the fill valve float may be set too high, allowing water to enter the overflow tube. Our technicians replace the flapper seal and adjust the fill valve height. Homeowners can gently lift the tank lid and press the flapper down to stop the flow temporarily.
How is a leaking water heater temperature and pressure relief valve diagnosed?
Technicians test the valve by lifting the lever and checking for proper reseating. They also measure tank temperature and pressure to see if expansion has exceeded limits. Homeowners should never cap the discharge pipe and can note whether water continues to drip after the lever is released.
What causes a toilet to rock on the floor?
The wax ring has compressed or the closet flange has shifted, breaking the seal between bowl and drain. Technicians check flange height and install a new ring or spacer. Homeowners should avoid rocking the fixture further and can place a towel at the base to absorb minor seepage.
Sewer, Pipe, and Fixture Questions
What indicates a sewer line obstruction rather than a fixture clog?
Multiple drains back up at once and gurgling occurs in tubs when the toilet is flushed. Technicians insert a camera through a cleanout to locate the restriction. Homeowners should stop running water and note which fixtures are affected before service reaches the property.
Why do pipes bang when a faucet is turned off quickly?
Water hammer occurs when momentum slams against a closed valve and the pipes lack air chambers or cushioning. Technicians inspect accessible stops and may add arrestors. Homeowners can open the faucet slowly and avoid sudden shutoffs on laundry valves.
What steps are taken during repiping of an older home?
Technicians map the existing runs, isolate sections, and replace copper or galvanized lines with new PEX or copper while maintaining fixture supply. They pressure test each branch before restoring service. Homeowners can label which rooms will lose water and prepare towels near shutoff points.
How are new fixtures installed without disturbing finished walls?
Technicians use existing shutoff valves or add access panels behind the fixture. Supply lines are routed through cabinets or soffits when possible. Homeowners can measure the rough-in distance from the wall to the drain and confirm the new fixture matches that dimension before delivery.
