"Robert and his crew were great. They were able to replace my rusty old drain pipes that had developed a hole in one pipe and replace them. The drain system works great and I appreciate the hard work and effort in just finding the parts needed for my almost 100 year old plumbing and getting the replacement parts installed quickly so I could use water again. Thank You Robert and the Facilities and Plumbing Crew!"

"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 ."

Customers say: Quality work

"Jay is very responsive to my inquiries. Jay and George Albert did a very good job in cleaning up the clogs of our bathroom sink pipe and kitchen drain pipe. With George onsite and Jay providing guidance, the trouble shooting of our drain pipe clog was done smoothly and successfully. George is a happy person. He was smiling and singing when working on a complicated drainage clogging problem. We were very happy with the service from Jay and his team. I would highly recommend Jayâ s Precise Plumbing company to work on plumbing jobs. Thanks to Jay and George Albert for their excellent service!"

"Gerardo was great: on time, courteous, explained and cleaned up things well. I was able to get a same-day appt. which worked out really well for me. After cleaning my clogged drain he was able to fix an old shower hot water faucet that was worn out. The only thing that would have been nice is to have a written receipt before Gerardo left the jobsite. He said his office will send me one."

Drain Cleaning FAQs, answered by experts

A professional drain cleaner is a plumber or specialized drain cleaner with the necessary tools to unclog drains and tiles to keep waste water flowing out to the septic tank or city sewer for processing. Keeping wastewater from backing up into your home helps keep you and your family safe from potential contamination and sickness. These pros can help resolve nearly any drain situation in a safe and efficient manner.

Start by pouring hot—but not boiling—water down the drain. The heat of the water may be enough to break down the clog. You can also try ½ cup of dish soap or 1 cup each of white vinegar and baking soda. If you choose a chemical unclogging product, ensure it’s appropriate for toilets to avoid damage.

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.

If your dishwasher keeps filling with water at the bottom but doesn’t fill into the sink, the issue is likely due to a blockage within the dishwasher or drain. Regularly clean your dishwasher filter basket to ensure it’s not clogged with food, and run a vinegar rinse periodically if you have hard water to remove limescale buildup.

There are a couple of things you can do to help prevent your French drain grate from clogging. First, keep yard debris clear so it doesn’t wash into the drain and clog the grate. You can also install a screen or filter over the grate to prevent large pieces of debris from entering the access point.
