"I usually don't do reviews but I had a great experience with Ralph in getting my kitchen sink unclogged and I hope this review helps other people know about the plumbing service that Ralph and his assistant, Peter provide. They were able to quickly assess the problem and provide me a reasonable and fair estimate of the cost. Both were very professional, methodical, pleasantly direct and quick in resolving the problem. I will be a repeat customer. I will also add that when i did my scheduling for an appointment for Angi's lists of plumber/s to do the job - Ralph was the first one to reach out to give me a time and date. Thank you again -Ralph and Peter."

"Jimmy was amazing. My boyfriend and I were in a serious bind when water started leaking into our kitchen from the bathroom upstairs after we just moved in. I called a handful of other plumbers who wanted to charge us an estimate to come, wanted me to send pictures for an estimate or quoted an exorbitant amount without a clear plan due to the complexity of our issue. I was starting to get really worried until I called Titan. Jimmy was professional, personable and fairly priced. He came that night and determined a plan for a permanent fix. The next day he rerouted all the pipes and corrected the issue in no time. We are so grateful we found him!"

"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."

"Needed leaky water valve repaired and sewer system unclogged. Came within 45 minutes of my desperate phone call. Installed new valve and new copper piping. Could not flush clog from inside, so came next day and dug 7' hole in front garden to remove the clog. Also installed vertical pipe to access any future sewer problems. Work crew had to dig out two big bushes to access the old sewer pipe at my home's foundation but replanted them along with any tulip bulbs they displaced. Truely considerate of my early spring garden! Courteous, mindful of property, work done in a timely fashion at a fair price. Explained each step in the process and why it was needful. Very pleased with 'Moose' and his work team."

"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."

"Our hot water heater stopped working. Within 24 hours, Intact Plumbing had installed a brand new heater, and was able to honor our warrantee on the old one. They were efficient, polite, and professional. All around excellent."

"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!"

"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."

Plumbing questions, answered by experts

If you've discovered a rather frightening buildup of brown and black gunk below your shower cover, you're not alone. The smelly sludge is often a collection of mildew and biofilm. Biofilm comes from the breakdown of soap scum, hair, skin cells, and bacteria that collects during shower time. It's quite common in a humid space and relatively easy to clean with a gentle DIY cleaning solution such as baking soda and vinegar.

Yes, copper pipes can freeze, crack, and burst in cold weather. In fact, of all piping types used for plumbing, copper pipes burst most easily when frozen. This is because copper conducts energy and loses heat more quickly than other types of plumbing. Copper also won't expand when the water inside freezes. Instead, it bursts or splits to accommodate expanding frozen water.

Silicone caulk—despite having some adhesive properties—is not the primary thing that holds your sink in place. Rather, it seals the gaps around the sink to prevent water from leaking and causing issues with mold and corrosion. Most sinks are secured by clips, though some sinks are secured with two-part epoxy or brackets.

Toilets typically connect to your main vent stack, a vertical pipe that runs through all finished levels of your home and exits through the roof. It’s located behind the walls, but if you have an unfinished basement or a utility closet, you may find a portion of it running the vertical length of the space. Some basement toilets use an air admittance valve instead, which is a small vent located in the wall directly behind the toilet that extends upward a few feet from the drain.

No, you typically cannot use metal detectors to find your sewer line. Most sewer lines are made of non-metallic materials such as PVC, clay, or cast iron, which are not detectable by standard metal detectors. Metal detectors are designed to locate metallic objects, so they won't be effective for identifying the path of a non-metallic sewer line. To locate your sewer line accurately, it's best to use other methods.
