Frequently Asked Questions About John H Coleman Co
Will my pipes freeze in one night?
Yes, pipes can freeze overnight. Freezing can occur in as little as six to eight hours, especially if the outside temperature drops below 32 degrees Fahrenheit and your pipes aren't properly insulated. For more information or assistance with water heaters in the Knoxville area, please don't hesitate to contact us.
How do you unclog a toilet when the water is high?
If your toilet bowl is full, first remove some water to prevent overflow. Then, pour one cup each of baking soda and vinegar down the drain. The resulting chemical reaction should help loosen the clog. For severe blockages, we recommend contacting us for professional toilet and drain cleaning services in Knoxville.
Why is the water in my toilet running?
Continuous toilet running is often caused by a faulty flapper, incorrect chain length between the flush lever and flapper, or a misaligned float. These issues can be tricky to fix without proper training. For expert assistance with toilets and water heaters in Knoxville, please give us a call.
Why does my shower faucet keep dripping?
A dripping shower faucet typically indicates a problem with the faucet or valve. Common causes include worn inner seals, hard water deposits causing clogs or corrosion, and deteriorated O-rings or gaskets. For a thorough assessment and professional shower drain cleaning, we encourage you to contact us.
How do you know if your sewer is clogged?
Signs of a clogged sewer include multiple backed-up drains, drainage in a sewer clean-out, visible sewage in floor drains, or water backing up in your shower when flushing the toilet. These issues can significantly disrupt your home life. If you notice any of these signs, please contact us promptly for reliable plumbing and electrical services in Knoxville.
What's the difference between drain clearing and drain cleaning?
Drain clearing focuses on removing large debris causing blockages, such as hair clumps or hard deposits. Drain cleaning involves using pressurized water to flush out any remaining debris after clearing. For professional drain cleaning services in Knoxville, we invite you to reach out to us.
How do I stop my house lights from flickering?
To address flickering lights, ensure bulbs are securely tightened in their fixtures and lamp plugs are firmly inserted into outlets. If you're using a non-dimmable bulb with a dimmer switch, this could be the cause. For more information or to request service from experienced Knoxville electricians, please contact us.
What causes a circuit breaker to trip?
Circuit breakers typically trip when there's an electrical fault that could damage the circuit. This may be due to excess current, a power surge, or a faulty component. If you need assistance with your breaker or information about generators in Knoxville, we're here to help.
How do you fix a breaker that keeps tripping?
Circuit overload is a common cause of tripping breakers. As a temporary solution, try using fewer appliances simultaneously on that circuit. For a long-term fix, consider having an electrician update your home's wiring and add more circuits. Our team of skilled Knoxville electricians is ready to assist you with this task.
What wiring do you need for a ceiling fan?
For ceiling fan wiring, copper or green wire serves as the ground wire to prevent power surges. If you see blue and black wires from the household circuit, there should be two wall switches. A red wire from the ceiling indicates a connection to the wall switch. For more detailed information about wiring, please contact our experienced Knoxville electricians.
