General Plumbing Questions

Do I need a plumber or can I fix this myself?  Some small issues, like replacing a toilet flapper or unclogging a minor drain, can be handled DIY. But leaks, slab issues, water heater problems, or recurring clogs usually require a licensed plumber. Attempting bigger repairs yourself can lead to more costly damage. Our Keller plumbing team provides upfront options so you know when it’s smarter to call a pro.

What should I do in a plumbing emergency before a plumber arrives? First, shut off your home’s main water supply to prevent flooding. If it’s a gas water heater leak, turn off the gas as well. Move valuables away from the area and call a licensed plumber immediately. At Howze Plumbing, our emergency plumbers in Keller and Southlake respond quickly to minimize damage and restore peace of mind.

Why is my water bill suddenly so high?  A sudden spike usually points to a hidden leak: common culprits are slab leaks, running toilets, or dripping faucets. Even a small leak can waste thousands of gallons of water each month. Our leak detection specialists in Colleyville and DFW can locate the source and fix it fast.

Water Heaters

How long should a water heater last in Texas?
 Most water heaters last 8–12 years, but hard water in North Texas often shortens their lifespan. Tankless models can last up to 20 years with proper maintenance. If yours is over 8 years old or showing signs of rust or leaks, it’s time to explore replacement options.

What are the signs my water heater is failing?
 Watch for rusty water, loud popping sounds, inconsistent hot water, or leaks around the base. These are red flags that your water heater is nearing the end of its life. Our team in Keller offers repair or replacement solutions tailored to your budget.

Should I repair or replace my water heater?
 If your water heater is under 8 years old and the issue is minor (like a thermostat or element), repair makes sense. But if it’s older, leaking, or inefficient, replacement is often more cost-effective. We provide both tank and tankless options for homeowners in Southlake, Keller, and beyond.

Drain & Sewer

Why do my drains keep clogging even after cleaning?
 Recurring clogs usually mean there’s a deeper issue in your sewer line: like roots, grease buildup, or pipe damage. Store-bought cleaners only provide a temporary fix. A camera inspection or hydro-jetting from a professional plumber in Keller can solve the problem for good.

What’s the difference between drain clearing and hydro jetting?
 Standard drain clearing clears immediate blockages, while hydro jetting or drain cleaning uses high-pressure water to scrub the entire inside of your pipes. Hydro jetting is especially effective for grease, sludge, and tree root problems common in older DFW homes.

How can I tell if I need a sewer line repair or replacement?
 Slow drains throughout the house, foul odors, soggy spots in the yard, or sewage backups often point to a failing sewer line. Our plumbers in Colleyville and Keller use video inspections to show you the exact condition of your line and recommend spot repairs or full replacement if needed.

Leak Detection & Slab Leaks

What causes slab leaks in Texas homes?
 Shifting soil, corrosion from hard water, and poor installation are the most common causes. In North Texas, clay soil expansion and contraction can put extra stress on pipes under the foundation. Our slab leak experts in Keller specialize in detecting and repairing these issues quickly.

How do I know if I have a hidden water leak?
 Unexplained water bills, warm spots on the floor, low water pressure, or the sound of running water when fixtures are off are all warning signs. We use advanced leak detection technology to pinpoint leaks without tearing up your home.

Will my homeowners insurance cover a slab leak repair?
 Policies vary, but many cover the cost of accessing and repairing the leak, though not always the plumbing itself. Our team can provide detailed reports for your insurance company to help maximize coverage.

Water Quality & Filtration

Is Keller / Southlake tap water safe to drink?
 Yes, city water meets minimum safety standards, but it often contains chlorine, minerals, and other chemicals that affect taste and damage plumbing. That’s why many homeowners install filtration or softening systems for better water quality and longer-lasting pipes.

Why is my water cloudy or discolored?
 Cloudy water is often caused by air bubbles, while brown or rusty water may signal sediment or corrosion in your pipes or water heater. Our plumbers can test your water quality and recommend filtration solutions for cleaner, healthier water.

What is hard water and how does it affect my plumbing?
 Hard water is high in calcium and magnesium, which build up inside pipes, faucets, and water heaters. This shortens appliance lifespan and lowers efficiency. A water softener helps protect your plumbing and saves money long-term.
