"Glenn and Josh are great guys. We had an emergency with Sewer blockage and they were at our house within an hour on a Friday evening. They cleaned it and also pointed out that we had old cast iron pipes which had cracks. Subsequently, we engaged them to replace all our sewer lines. The work was done within 3 - 4 days and they kept us up to speed on every aspect. The work was excellent (and they showed pictures to prove it). We would hire them for any of our plumbing needs and highly recommend them!!"

"As shown in the photos, my kitchen drain line was a mess and needed to be replaced. Cornelius did an excellent job managing all aspects of the job. He showed us pictures documenting the problem and provided us with a detailed estimate. Then, he and his team completed the work on time and budget -- all while working around our time constraints. Throughout the job, he did an excellent job communicating progress and giving us "heads up" about potential challenges. He is friendly, courteous, knowledgeable, respectful, and professional. Without reservation, we will call him again for our next plumbing problem!"

"**Robert was very calm, cool, and collected!!!! I got a call from my tenant at about 1p on a Sunday afternoon, that her kitchen ceiling was leaking water. I suspected there was a plumbing issue right away, and I reached out to Robert. Instantly, Robert said he would go take a look after he completed his job across town. Heroically, Robert made it there in about 30 mins and discovered the issue was a clogged pipe, and used all his tools in his belt to help me clear the clogged drain issue. Long story short -- he fixed everything before 3p 😮😮😮 Thank you Robert!! You are the man!! I will call you without hesitation moving forward!!!"

"Wilmar Plumbing was very responsive and empathetic towards my situation. They had to fix a problem caused by the previous plumber who installed my shower/tub drain incorrectly. I couldn't shower due to the leak. They treated my case like the emergency it was and Wilmar and his team showed up first thing. They fixed it diligently. They were so good, I hired them to install new bathroom sinks. These guys are great!"

The specialist diagnosed the problem in about five minutes and had everything fixed in fifteen. No fuss, no surprises on the bill. Really happy with the experience and will definitely call them again."

"The folks @ Mike Counsil have done work for us in the past, including the heater installation and unclogging/cleaning a backed up drain. Any time we've had work done by them, they are always right on time and very professional. They get the job done and clean up after they're finished to ensure there's no clean up for the customer. I highly recommend them for all of your plumbing needs."

French Drains FAQs, answered by experts

A clogged air gap can cause a dishwasher not to drain. There are, however, other potential issues that can lead to improper drainage. For example, if you have attached the air gap to a garbage disposal and forgotten to remove the knockout plug, wastewater may backflow into the dishwasher. Check that the air gap is installed properly, and then look for clogs in the air gap and dishwasher filters. 

A washing machine should drain the water used during its cycle through a drainpipe and out through the house’s plumbing. This is the same plumbing that sinks and shower drains run to, and if the U-bend is installed correctly, it shouldn’t smell. The total drainage from the house is then integrated into the city sewer system or, if you’re in the country, dispersed into a septic tank.

No, you should avoid using liquid drain cleaners. These chemicals, often packed with sulfuric or hydrochloric acid, can wreak havoc on your pipes, causing erosion and potential leaks. They’re also dangerous to your health. If you’re dealing with a stubborn clog, manual removal or a professional plumber is your best bet. Chemical drain cleaners can often make things worse, especially if the clog stays put and the chemicals linger in your pipes.

Drain pipes carry wastewater from sinks, toilets, showers, and other fixtures to the main sewer line. They’re typically located within the walls and floors and beneath a home’s foundation. Meanwhile, sewer pipes transport collected wastewater to a septic tank or a municipal sewer system.

In most areas, drain cleaning professionals don’t technically need a license, as they aren’t altering your plumbing system in any way. However, we recommend hiring a drain cleaning professional with a plumbing license and certification. Certified plumbers are more likely to provide professional solutions to drain clogs without damaging your system. They’ll also have the diagnostic tools and experience necessary to remove the clog entirely rather than providing a temporary solution, as a handyperson might. Use Angi’s state licensing tool to check your plumber’s professional licenses before hiring.
