"Exchanged messages with Mike to describe work needed, replace an outdoor faucet and shutoff value (previous faucet was leaking). He gave an estimate, reviewed work to be done. Replaced outdoor spigot with a frost-proof spigot, put on new value. Quick test and validation. Professional, efficient and happy with work done! Thank you Mike !"

"The plumber showed up on time, was pleasant and because it was snowing he took the time to cover his shoes. We had a leak in our shower/tub combo that 2 other professionals were unable to fix. He spent about an hour and a half located the problem and it hasn't leaked since."

Plumbing questions, answered by experts

The most common types of backflow preventer devices depend on the purpose of the installation. For example, Portland.gov states that the double-check valve assembly and the pressure vacuum breaker assembly are most commonly used in irrigation systems, while the National Fire Protection Association (NFPA) states that double-check valve assembly and the reduced pressure zone assembly backflow preventers are best for fire protection systems.

Ask a plumber for recommendations on the best backflow preventer device for your home.

Installing a drain pipe costs about $600, ranging from $150 to $2,000, depending on the type of drain, accessibility, proximity to drain lines, and whether you’re installing new drain pipes or replacing old ones. Replacing a main drain line can cost over $2,000, whereas replacing a p-trap costs around $150 on average. Keep in mind that new water pipe installation projects are bid by fixture, like kitchen sink, toilet, or main water line. You can expect to pay $70 to $1,000 per fixture.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

A sewage ejector pump is necessary if you have any plumbing fixtures, such as a bathroom, laundry room, or sink, located below the level of your home's main sewer line. Standard plumbing relies on gravity to move wastewater and solid waste to the municipal sewer or septic tank. However, for fixtures located below grade (e.g., in a basement), gravity is not sufficient.

The purpose of a sewage ejector pump is to actively pump this wastewater and solid waste upward into the main sewer line. Without an ejector pump in this situation, wastewater would have no way to exit and would eventually back up, causing a sewage overflow or flooding in your basement. If all of your home's plumbing is on the main floor or higher, gravity can handle the drainage, and an ejector pump is not needed.

If you're replacing a similar model, you don’t always need a plumber to install a bathtub faucet since it will fit over the existing plumbing. That said, there is some room for error. If you’re uncomfortable with working on your plumbing, your installation is more complex than a simple replacement, or the piping is old and corroded, call a pro to handle the job.
