"Adam , the plumber , is a professional. He explains the issues patiently and logically . My sewer line was clogged up and he used the snake and camera to show me the roots that were causing the problems . He recommended hydro blasting the line in order to remove roots. He responded within minutos of posting on Angie's list. He was puntual and started the job on a Saturday afternoon and completed on a Sunday ."

"I requested a plumber to replace/repair a leaking outdoor faucet. Harry responded to my request and repaired the faucet on a Sunday! Courteous and professional work. As an added project I told him I wanted to replace an existing toilet in a downstairs bath. We went together to Home Depot to purchase a replacement (per his recommendation), which he then installed the same afternoon! Harry will be my first call for any future plumbing work."

Plumbing FAQs, answered by experts

Unfortunately, pipes can freeze when exposed to prolonged freezing temperatures, whether or not you have installed insulation covers. Insulation covers, however, are still an excellent idea as they can reduce the chance of your pipe freezing by keeping the pipes closer to the temperature of the water inside the pipe.

Different plumbing problems can cause your P-trap to leak. The biggest problems are loose nuts and misaligned pipes. Over time, your P-trap can leak due to the rush of water moving through the pipes, which in turn loosens the nuts and causes the pipes to fall out of alignment. Other problems include worn rubber O-rings and cracked pipes.

For homes with a septic tank, harsh chemicals like those found in drain cleaner or bleach aren’t recommended. Some chemical drain cleaners can disrupt the balance of bacteria in the septic tank or damage your pipes. For homes with a septic tank, you can choose drain cleaners specifically formulated for use with septic tanks or go with a drain snake. When in doubt, make sure you know who to call for a clogged drain. 

Chemical drain cleaners can work to clear clogs in pipes, but their use should be approached with caution. These harsh chemicals can damage pipes over time, and they can also harm the environment. Use them sparingly and consider alternative methods such as using a plunger or a drain snake. If you have concerns about a persistent clog, it's best to consult a professional who can safely and effectively address the issue without causing further damage to your plumbing system.

Common signs of gas line leaks include a rotten egg smell, hissing sounds, dead plants around the area of the leak, and unexplained physical symptoms like dizziness and nausea. If you notice any of these signs, act immediately. Shut off the gas supply to your home and call a pro to assess the situation.
