"Al did an excellent job replacing the faucets(bibs) and drain for my laundry closet. He even patched the cut-out sheet rock that needed to be made for the replacement. Other plumbers I got estimates from would not do the patching. Also, he replaced the cartridges for my shower valves. I’ll definitely call him again for any future work."

"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 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."

"Had our garbage disposal replaced by Core Plumbing Solutions and while under the sink, found the sink was leaking and there was a hole in the drain pipe going into the wall that you could put your little finger in. Core replaced all the piping under the sink with ABS, plus install the new garbage disposal for one hell of a great price. Great job Core Plumbing Solutions."

French Drains FAQs, answered by experts

Air gaps get clogged by a few different means. Over time, food and grime can collect in the air gap, leading to a blockage. Mineral deposits from hard water are a common problem. Mineral buildup creates a film in the air gap and tubing, which can cause flow issues, as well as attract debris. Homeowners with hard water may want to remove mineral deposits regularly to keep the air gap clean and clear.

It can take anywhere from half an hour to a few hours to fix a main line clog, depending on the cause and severity of it. The job should not take more than a day to complete. Keep in mind that the main line is not the same as your home’s sewer lines (which connect to the main line and run to your house). Your city is responsible for any clogs or damage to the main line itself.

Yes, flushing a clogged toilet can make it overflow. While flushing the toilet may push enough pressure through the system to dislodge the clog, this is unlikely. Your best bet is to use a plunger and hope the suction can break up whatever is blocking the pipe. If this doesn’t work, use a plumbing auger or call a pro to help.

If you want to avoid using a snake to unclog a drain, or if you don’t have one, try vinegar and baking soda. Pour 1 cup of baking soda down the drain, followed by 1 cup of white vinegar. Wait for 15 minutes, and then run hot water (but not boiling water) down the drain to see if the clog is clear. Repeat multiple times as needed.

To clean gunk out of a sink drain, pour in a half cup of baking soda, then 1 cup of white vinegar. The two will react chemically; let them fizz for 15 minutes, then rinse with boiling water. Repeat these steps if necessary for particularly dirty sink drains, and consider a drain snake if there are clogs.
