"Ralph and his assistant Peter did a great job. They were personable and arrived promptly. The work went smoothly and now I've got a working faucet again. I'd recommend Ralph and his company for any plumbing jobs you might need done if you're looking for a reputable, qualified and excellent plumber."

"Fast, Clean, Efficient, Feasible! This is an easy review to write when you have a professional on the job. Titan Plumbing Sewer & Drain was on site ready to swap out our old tank and install the new one. Also, was aware of new housing codes and installed an Expansion Tank. He could of easily changed the thermocouple just to get by but did not recommend doing so on a 10+ unit. Do it right once and call Titan Plumbing Sewer & Drain. We were so happy with their service! Easy to recommend them"

"We have used Gene from Preferred Plumbing on several occasions. We had a water heater replaced and multiple faucets, hose bibs changed or repaired, and drain / sewer clogs. Gene was responsive, courteous, and explained the issue and required work clearly. The work was completed without issues and reasonably priced. I recommend Gene (Preferred Plumbing) for any plumbing issues / work."

"Abraham did an excellent job of getting clogged bathroom sink and a shower stall working again. He additionally changed some old pipes in the basement. I particularly appreciate the fact that he took his time to tidy up after self and didn’t leave us with a mess. I would hire him again."

"I recently had plumbing work done and had the pleasure of working with Gashi. He was incredibly kind, respectful, and thoughtful throughout the entire process. Although the project turned out to be more extensive and needed to be escalated, Gashi handled his part with great professionalism and care. He took the time to explain things clearly and made sure everything was left tidy. I truly appreciated his friendly attitude and attention to detail. Highly recommend Gashi for anyone looking for reliable and considerate plumbing service."

"Mo was absolutely amazing. Possibly the best contractor I have ever hired. Had a situation with a clog in my main sewer line and he was extremely quick to respond. Even before arriving at the house he did a FaceTime to diagnose the situation and give me peace of mind. He moved his schedule around to come first thing in the morning the next day and his customer service throughout was great. He walked me through everything that he was doing and gave me counsel on how to avoid situations in the future along with different options. Saved his number because I will absolutely use 123 Sewage again!"

Plumbing FAQs, answered by experts

The cost to unclog a drain varies based on the location and severity of the clog. For simple clogs within your home, such as in a sink, toilet, or shower, hiring a plumber typically costs between $110 and $350, with an average of around $200. Snaking a toilet or sink usually costs between $110 and $275, while a bathtub or shower clog costs about $225.

For a more serious clog in the main sewer line, the cost is higher. Clearing a main line clog generally costs between $200 and $600, with an average of about $380. However, prices can range from as low as $100 for snaking a minor clog to over $1,600, particularly if advanced methods like video inspection and hydrojetting are needed for a large or hard-to-reach blockage. Some severe main line clogs can cost upwards of $1,000 to clear depending on factors like the cause of the clog, its distance from an accessible cleanout, and whether the pipe is located beneath an occupied space (e.g., in an apartment building). You may be able to save money on minor clogs by using a drain snake or bladder yourself.

In the warmer months, it’s fine to leave your garden hose attached to your spigot. However, before the first frost of the year, make sure to disconnect your hose from your outdoor faucet and drain any leftover water inside. Otherwise, water could freeze in the hose and potentially burst inside your faucet or pipes.

You can often identify a freeze-proof faucet by its structure. Unlike a traditional spigot, a freeze-proof one will include a long supply pipe that extends into your home and connects several inches back to your water supply. Many freeze-proof models also have an extra valve on top of the exterior of the spigot, which is the anti-siphon feature that protects against water backflow.

To clean gunk out of a sink drain, pour in a half cup of baking soda, then 1 cup of white vinegar. The two will react chemically; let them fizz for 15 minutes, then rinse with boiling water. Repeat these steps if necessary for particularly dirty sink drains, and consider a drain snake if there are clogs.

Switching to city water from well water requires running a private main service line from the closest main city line to your home. When comparing well water versus city water, city water is routinely tested and readily available but can be more expensive than well water.
