"Plumber was punctual and completed work in professional manner.  In fact, he found a potential plumbing problem with gas dryer connection that could have caused additional problems.  I have used this company before and once again they lived up to their A rating.

"Aidrian is the best! I had an emergency leak late on a Sunday night and he came right out and fixed everything, game me advice on how to handle repairs and educated me on what to do in the future if that happens. I then had him come out another time to install a garbage disposal. He is so easy to contact, on time, clean, professional and gave me a far better price than anyone else quoted. Itâ s great to see the price he takes in his work. A real perfectionist! He is the only person id trust for future plumbing related issues at my new house."

Plumbing questions, answered by experts

Pipes are connected in a bathroom by a 3/4-inch to 1-inch line running from your water meter into your home. The line then splits, with the hot water line going to your water heater and the cold water line running into your home. The cold water line leads to the 1/2-inch water supply lines for your home’s toilet, tub, and sink. The hot water line runs from the water heater to all sinks and baths.

While you can complete this task if you have some DIY knowledge, it is recommended that you hire a plumber to ensure that the work is done correctly and safely. This is especially true if a new water line needs to by installed from scratch, as this process requires cutting into pipes or walls.

Although air in your water lines won’t affect the overall quality of your water, it will lead to problems with your well water system if not addressed. Over time, too much air in your water lines can create blockages in your pipes, cause insufficient water flow to your taps and appliances, loosen pipes, and potentially damage important components of your well including your well pump and pressure tank. 

If the shut-off valve to your kitchen sink appears to be stuck or broken, there's no need to panic! The workaround is to turn off the main valve that supplies water to your entire household. This valve is located along the main water line. Of course, it's also important to have a plumber repair the malfunctioning shut-off valve under your kitchen sink because this indicates a problem.

A backwater valve’s purpose is to let the water flow in one direction. It works like a little door that allows water to flow freely in one direction but stops it from flowing the opposite way. A backflow preventer is meant to prevent water from leaving your system, locking out wastewater in the process. Backflow preventers are commonly used by city sewer systems to stop residential wastewater from entering the water supply.
