Plumbing Questions Answered

If your shower isn’t getting hot but other fixtures in your home have hot water, the issue likely lies within the shower valve or mixing components rather than your water heater. One common culprit is a faulty thermostatic mixing valve (TMV) or pressure-balancing cartridge, which regulates the mix of hot and cold water in your shower.

Over time, these valves can wear out, become clogged with mineral deposits, or get stuck, preventing the proper flow of hot water. This is especially common in homes with hard water.

Another possible issue is a misadjusted anti-scald device, a safety feature inside the shower handle that limits how hot the water can get. If set too low or out of alignment, it can block hot water flow entirely.

In rare cases, incorrect plumbing connections or cross-flow between hot and cold lines can also affect shower temperature, especially in older or remodeled homes.

To diagnose and fix the issue properly, contact A&G Plumbing and Drain. We serve Metro Atlanta, Marietta, and surrounding areas with expert troubleshooting and fixture repair to get your shower running hot again.

Gurgling or popping sounds coming from your drains are typically signs of air trapped in the plumbing system, usually caused by a partial clog or a venting issue. When wastewater flows through your pipes, it displaces air. If that air has nowhere to escape—due to a blockage or a malfunctioning vent—it creates negative pressure, resulting in the gurgling or bubbling noises you hear.

Common causes include buildup of grease, hair, or debris in the pipes, or a blocked plumbing vent (often located on the roof). These vents are essential for balancing air pressure and allowing water to flow freely through your drain lines.

In some cases, improper pipe installation or older, undersized plumbing systems may also contribute to poor drainage and gurgling noises.

To prevent further damage or backups, it’s important to have a professional plumber inspect the issue. At A&G Plumbing and Drain, we serve Metro Atlanta, Marietta, and surrounding areas with expert drain diagnostics and safe cleaning solutions to restore quiet, efficient flow to your plumbing system.

For basic kitchen or bathroom faucet replacements, the job typically involves shutting off the water supply, disconnecting the old faucet, cleaning the mounting surface, installing the new fixture, and checking for leaks. This process can usually be completed in under an hour with the right tools and access.

Complications may arise if shut-off valves are corroded or stuck, the plumbing under the sink is outdated, or if there's water damage or mineral buildup. In these cases, it’s best to call a professional to ensure a safe and long-lasting installation.

At A&G Plumbing and Drain, we handle faucet replacements efficiently and can spot any hidden plumbing concerns before they become bigger problems. Whether you're upgrading fixtures for style or resolving a leak, we serve homeowners throughout Metro Atlanta, Marietta, and nearby areas with expert service and quality results.

While chemical drain cleaners may offer a quick fix for minor clogs, they are generally not a safe or long-term solution for your plumbing system. Most commercial drain cleaners contain harsh acids or caustic substances that can corrode your pipes over time—especially if used frequently or in older homes with metal or PVC piping.

These chemicals can also pose health and safety risks. Fumes can irritate your eyes, lungs, and skin, and if mishandled, they can cause serious injury. Drain cleaners are also harmful to septic systems and the environment when washed into the water supply.

Better alternatives include mechanical methods like plungers or drain snakes, which clear clogs without damaging your plumbing. A natural home remedy—pouring a mixture of baking soda and vinegar down the drain followed by hot water—can also help loosen minor buildup safely.

For recurring or stubborn clogs, professional drain cleaning is the safest and most effective choice. At A&G Plumbing and Drain, we offer safe, non-corrosive methods to clear your drains quickly without harming your pipes or your home.

Preventing drain clogs in your home starts with everyday habits and regular maintenance. Clogs form when debris, grease, or buildup restricts water flow over time. Following a few simple tips can keep your drains running freely and avoid the need for emergency service.

1. Don’t pour grease or oil down the drain: Grease solidifies as it cools, sticking to pipe walls and trapping other debris. Instead, pour it into a container and dispose of it in the trash.

2. Use drain strainers: Install mesh strainers or hair catchers in kitchen sinks, tubs, and showers. These inexpensive tools trap food particles, hair, and soap scum before they enter your plumbing system.

3. Run hot water after use: After using the kitchen sink, run hot water for 15–30 seconds to help flush away any residual grease or food waste that could cause buildup.

4. Avoid flushing non-flushable items: Only flush toilet paper. Items like wipes, paper towels, cotton swabs, and hygiene products can easily clog your sewer line.

5. Clean drains regularly: Once a month, flush your drains with a mixture of hot water, baking soda, and vinegar. This natural solution helps break down buildup without damaging your pipes.

For stubborn or recurring clogs, A&G Plumbing and Drain offers professional drain cleaning services across Metro Atlanta, Marietta, and surrounding areas.

In a plumbing emergency, acting quickly can help minimize water damage and repair costs. Follow these essential steps to protect your home and safety until help arrives.

1. Shut off the water supply: Locate your main water shut-off valve—usually near the water meter or where the main line enters your home—and turn it off immediately to stop the water flow. For localized issues like overflowing toilets or leaking sinks, turn off the valve under the fixture.

2. Turn off the water heater: If the emergency involves hot water or flooding near the heater, turn off the unit to prevent damage or overheating. For gas heaters, shut off the gas supply as well.

3. Open drains and faucets: After shutting off the water, open nearby faucets to relieve pressure and help drain remaining water from the pipes.

4. Contain and assess the damage: Use towels, buckets, or a wet/dry vacuum to contain water. Move belongings out of affected areas and take photos of the damage for insurance or record keeping.

5. Call A&G Plumbing and Drain immediately:

Low water pressure in your home can be caused by several issues, ranging from minor clogs to major plumbing problems. Identifying the source is the first step toward restoring proper flow.

One common cause is mineral buildup inside faucet aerators and showerheads. Over time, sediment and debris can restrict water flow. Unscrewing and cleaning these parts may quickly improve pressure in individual fixtures.

Another frequent culprit is partially closed shut-off valves or pressure-reducing valves (PRVs) that have been adjusted too low. Check that your main water valve and fixture valves are fully open.

Hidden leaks in your plumbing system can also lower water pressure. Leaks waste water and reduce the flow reaching your fixtures. Look for damp spots, unusually high water bills, or mold growth.

In older homes, corrosion inside galvanized steel pipes can restrict water flow over time, requiring pipe replacement. If your entire home has weak pressure, this may be the issue.

If you're unsure of the cause, A&G Plumbing and Drain can diagnose and fix the problem quickly to restore strong, consistent water pressure throughout your home.

Annual plumbing maintenance is essential for preventing costly repairs, improving water efficiency, and extending the life of your pipes, fixtures, and appliances. Proactive care helps catch small issues before they become major problems, protecting your home and budget.

Start by checking all visible pipes for corrosion, moisture, or leaks. Look under sinks, behind toilets, and around your water heater. Test all faucets and toilets for proper operation and inspect for slow drains, which could signal developing clogs.

Flush your water heater to remove sediment buildup that can reduce efficiency and lead to premature failure. Make sure shut-off valves operate smoothly, and inspect hoses on appliances like washing machines for cracks or signs of wear.

It’s also smart to schedule a professional inspection with A&G Plumbing and Drain. We can perform a full system check, test water pressure, evaluate drain flow, and spot hidden issues before they escalate.

With annual maintenance, you’ll enjoy peace of mind, better plumbing performance, and fewer unexpected emergencies throughout the year.

Detecting hidden water leaks early can help you avoid costly damage and water waste. Start by checking your water meter: turn off all water-using appliances and fixtures, then note the meter reading. Wait 1–2 hours without using water, and check again. If the reading has changed, you likely have a leak.

Look for signs like musty odors, mold or mildew growth, damp spots on floors or walls, bubbling paint, or warped wood. In bathrooms and kitchens, inspect under sinks and behind appliances for moisture or staining. Unexpected spikes in your water bill are another red flag.

Listen for running water sounds when no fixtures are on, especially at night. If you suspect a slab leak or pipe behind a wall, a professional leak detection service—like A&G Plumbing and Drain—can pinpoint the problem using thermal imaging or acoustic equipment.

Addressing hidden leaks promptly protects your home’s structure and can significantly reduce your monthly water costs.

A running toilet is usually caused by one of three common issues: a worn-out flapper, a misaligned float, or a faulty fill valve. These components regulate the flow of water from the tank to the bowl and control refilling after a flush.

First, remove the tank lid and inspect the flapper at the bottom of the tank. If it’s not sealing properly, water will continue to leak into the bowl. Try jiggling the handle to reseat the flapper or gently press it down to stop the flow temporarily.

Next, check the float—it should rise and stop the water once it reaches the fill line. If it’s too high, adjust it downward by turning the screw on top of the fill valve or gently bending the float arm if it’s metal.

If the water continues to run, turn off the shut-off valve located behind the toilet near the floor. This will stop the water supply until a plumber can inspect and repair the issue.

For professional toilet repairs in Metro Atlanta or Marietta, A&G Plumbing and Drain is just a call away—we’ll get your bathroom back to normal fast.
