"Steven was the absolute best… arrived at the very start of only a two hour window, fixed the problem in about an hour. Very polite and courteous. I called three plumbers and he was the first to call me back and the only one who would give me a ballpark figure over the phone. The others wanted to come out and have a look for $70. even though I accurately described the job in detail. I’m thrilled to have a reliable plumber! A more than satisfied customer, Lora Harrigan"

"Went well. I thought that I might need a new trap or elbow since water was leaking. As it turned out, it was the sprayer that was leaking and not the elbow. The tech did not try to oversell me all new plumbing and I appreciate that."

"I've used All Star Rooter on three occasions and have been very pleased with the work provided. Always professional, punctual and careful, they are specialists. An important indicator of their skill is their position in the industry - three different plumbing companies have recommended All Star Rooter. They will calmly approach a stressful situation and do their best to reach a successful outcome. On this occasion they were able to clear an on-going clog efficiently."

"Danny, from HL Bowman, quickly understood the scope of the installation and used his expertise to make the installation seamless. As a result, the filtration system he installed is now operating perfectly to remove particulates greater the 5 microns from our well water. I would highly recommend HL Bowman for your plumbing needs. "

"The team from Gallery of Kitchens & Baths gave our bathroom the upgrade it desperately needed. The Salvatori marble vanity and Pittori cabinetry make it feel brand new and incredibly stylish. The craftsmanship, communication, and professionalism throughout the process were outstanding. Kudos to them!"

Plumbing FAQs, answered by experts

You might think it’s OK to ignore a faucet that drips if it’s not too bad, but doing so can cause more damage. A leaky faucet can also increase water bills and potentially attract bugs and other pests to your home. When you find a water leak, it can result in water damage to your home, which can cause structural issues and mold growth.

Frost-free faucets are a smart idea if you live in a region that sees freezing temperatures. These specially designed faucets are typically insulated and feature a shut-off within the house. When temperatures drop, you’ll close the outdoor spigot so that freezing water doesn’t sit in the fixture and cause it to split or crack during cold weather.

The main shut-off valve for a sprinkler system is simply called the shut-off valve. It’s one of several valves for a sprinkler system, and it controls the water supply to the sprinkler system’s water lines. This valve is different from the master valve, which can also shut off the water supply in case of an emergency but operates automatically.

When it comes to PEX versus copper, you'll find that many plumbers prefer PEX, which doesn’t corrode or allow for sediument buildup and is less likely to burst under freezing conditions. PEX is also flexible, so your pro won’t need to install joints to create certain angles. Provided it’s up to local codes, your plumber can also snake PEX through smaller holes in the wall without making additional cuts.

Fix your leaking shower ASAP. By the time you realize your shower is leaking, chances are it’s been leaking for a while. Consider how often you use the shower to determine how much water has passed through the leak. Because shower leaks don’t fix themselves or get better with time, leaving them unchecked can lead to more damage and higher repair expenses. Use temporary fixes, but you should aim to have a professional repair your shower immediately.
