If you’re facing a plumbing problem or considering a DIY plumbing fix, here are answers to the most frequently asked questions—directly from our expert plumbers.

How Do I Use a Plumbing Snake?

A plumbing snake, also called a drain auger, is a flexible tool designed to break up clogs inside drainpipes or toilets. To use it, carefully feed the end of the snake into the drain while slowly turning the handle. As it moves through the pipe, it should catch or break up any blockage.

Once you feel resistance lessen, or the snake reaches its full length, pull it back out while continuing to turn the handle. After removing the snake, flush the pipe with hot water to clear away any remaining debris.

How Much Does a Plumber Cost?

The cost of a plumber can vary widely based on your location, the time of day, and the type of service needed. Hourly rates typically fall between $45 and $200.

For common services like unclogging a drain or installing a toilet, many plumbers offer flat-rate pricing. Keep in mind that emergency or after-hours visits often come with an added premium.

At United Air Temp, we believe in upfront pricing, so you’ll always know the cost before any work begins.

Does Homeowner’s Insurance Cover Plumbing?

Homeowner’s insurance typically covers plumbing issues that result from sudden, accidental damage—such as a burst pipe or unexpected water heater failure.

However, slow-developing problems like corrosion, clogs from neglect, or gradual leaks are often excluded. To enhance your protection, some insurers offer additional coverage for sewer backups or water damage through policy riders. It’s always a good idea to review your policy carefully or consult your provider for details.

How Do I Plumb a Shower Drain?

Plumbing a shower drain involves more than just connecting pipes—it requires careful attention to slope and ventilation. The drain line should have a downward slope of about ¼-inch per foot for proper drainage.

Beneath the drain, install a P-trap to block sewer gases from entering your bathroom. Once your connections are in place, test for leaks using water before sealing everything behind walls or under flooring. This step is crucial for preventing hidden water damage down the line.

What Does FIP Mean in Plumbing?

FIP stands for Female Iron Pipe. It refers to a type of threaded fitting where the threads are on the inside of the fitting, allowing it to connect to a MIP, or Male Iron Pipe, with external threads.

FIP connections are commonly used when attaching fixtures like faucets, water heaters, or valves. Knowing these terms can help you select the correct fittings and avoid mismatches that could lead to leaks.

How Does a Plumber Find a Water Leak Underground?

Detecting an underground water leak requires specialized tools and training. Plumbers often use acoustic listening devices and ground microphones to pinpoint the sound of escaping water.

Pressure testing can help determine whether a leak exists in the first place. For more precise detection, tracer gas, or infrared thermal imaging may be used to locate hidden leaks without having to dig up pipes.

How Long Does Copper Plumbing Last?

Copper plumbing is known for its durability and can typically last between 50 and 70 years under normal conditions. However, its lifespan can be shortened by factors like acidic water, poor initial installation, or excessive water pressure.

Keeping an eye out for early signs of corrosion, such as discolored water or pinhole leaks, can help you catch issues before they lead to major pipe failure.

Do I Need a Plumber to Replace an Outdoor Spigot?

Replacing an outdoor spigot is a manageable DIY job if you can access the connection point and shut off the water supply. Use thread seal tape and a wrench to install the new spigot securely.

However, if the spigot is soldered into place or the connecting pipe runs inside a wall, it’s safer to call a professional plumber. Improper installation can lead to hidden leaks that cause long-term damage.

Does a Plumber Replace Pipes?

Professional plumbers are fully qualified to replace everything from a single damaged pipe to an entire home plumbing system. Replacing pipes often involves opening walls, cutting into ceilings, or working in tight crawlspaces.

For major repiping projects, permits and inspections are usually required to make sure that the work meets local codes. A licensed plumber can handle every step of the process—from planning to completion—with minimal disruption to your home.

How Much Does a Plumber Charge to Replace a Toilet?

On average, replacing a toilet can cost between $125 and $350, depending on the complexity of the job and local labor rates.

If the floor flange is damaged or the subfloor has water damage, additional repairs may be necessary, which can raise the total cost.

While some homeowners opt to install a new toilet themselves, it’s important to follow each step carefully to prevent leaks and get a secure, level fit.

How Do I Plumb a Bathroom?

Bathroom plumbing requires a well-thought-out plan that accounts for drainage, water supply, and ventilation. Each fixture—whether it’s a toilet, sink, tub, or shower—has specific rough-in dimensions and spacing requirements.

Vent pipes must be installed according to code to prevent sewer gases from entering your home and to keep drains flowing properly. Getting the layout right from the beginning can save time, money, and headaches during construction or remodeling.

How Do I Plumb a Toilet?

Installing a toilet involves connecting it to your home’s drain and water supply systems. First, the closet flange is attached to the drainpipe and secured to the bathroom floor.

A wax ring is then placed on top of the flange to create a watertight seal. The toilet bowl is carefully set onto the flange, pressed down, and bolted in place.

Finally, the water supply line is connected to the tank, and the system is tested for leaks.

How Do I Plumb a Water Softener?

A water softener should be installed near your main water supply line and water heater. This allows all incoming water to pass through the softener before reaching your fixtures.

Use the correct fittings to connect the inlet and outlet pipes, and make sure to install a drain line for the backwashing cycle. An overflow drain should also be included as a safeguard in case of a system malfunction.

How Do I Plumb a Kitchen Sink?

Plumbing a kitchen sink starts with installing a P-trap underneath the basin to block unpleasant odors from the drain. If you have a dishwasher or garbage disposal, those connections will need to be tied into the drainage line as well.

To prevent leaks, use Teflon tape on threaded fittings and apply plumber’s putty to sink strainers or other seated joints. Make sure all components are securely tightened and aligned before testing for leaks.
