"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."

Customers say: Quality work

"ICR Plumbing provided exceptional service. I had a major problem where water was coming through the garage from the bathtub drain, "waste over flow " Israel was extremely knowledgeable and fixed the problem in less than a day's time. First he had to remove a heavy bookcase that was nailed to garage wall to access area, he removed and replaced all the sheet rock and pipe connected to bathtub. He did an awesome job and was very personable and honest, His price was reasonable. I would recommend him to anyone in need of home improvement, as he is knowledgeable in many areas and does great work! I will definitely call him again on more projects! He is The Best!. He went above and beyond his call of duty and helped me cut up other stuff with his electric saw so I could go to the dump. He even emptied my lawn mower bag for me which was not part of the job. He also is an expert at plumbing and has many years of experience."

"At first the company's name made us imagine they were just about clearing clogged drain lines, but we got superb service on a project to replace leaking shower faucets in the bathroom. Gerardo came to see what was needed and was very helpful in finding a quick and cost effective way to source the materials. He was completely committed to taking care of his customers. He returned to do the installation at the time we had agreed would be convenient for us, despite having been up working till all hours of the night on another emergency job. He even spent the time before returning to his emergency site to check and make sure the existing shower head was free of grit and working as it should. We absolutely will want this company, and him, for any future projects."

"Gabriel Nieto of GN Plumbing did a fine job. He was able to visually detect a leak where the line from the propane tank enters the house, and pressure tested the gas line from the propane tank to the house to confirm the leak. With the help of his assistant, he repaired the line (replacing worn out portions of the line) within a couple of hours, confirmed there were no other leaks in the line (via additional pressure testing), and re-lit the gas furnace and water heater. Only complaint is the extreme expense ($890)."

French Drains FAQs, answered by experts

Professional plumbers use many high-grade chemicals to unclog drains. Many use hydrochloric acid, known as muriatic acid, when it comes to extreme blockages. 

Septic tanks can clog if they aren’t pumped every few years since solid waste accumulates inside of them. Your tank might also clog if you have a habit of flushing anything other than human waste or toilet paper. Items like diapers, baby wipes, paper towels, cat litter, and personal hygiene products should never go down your pipes.

While you don’t have to run out and immediately buy a new toilet at the first sign of a clog, if the toilet keeps clogging because it’s a low-flow or poorly designed model, a new toilet may be the way to go. If your toilet keeps clogging, you can try using less toilet paper, adjusting the fill valve, checking the toilet vent pipe on the roof, and using a toilet auger to make sure nothing is stuck in the pipe or trap.

Vinegar is better for an AC drain line because it’s less corrosive and won’t damage the pipes. It’s also a safer and easier product to use. Bleach should not be used on your AC drain line because it can corrode your pipes and harm the evaporator coil in your air conditioner.

If your drain doesn’t have metal crosshairs or crossbars, you should use a tub drain extractor. These tools create a grip on the drain so you can turn it using a 1/2-inch ratchet drive, drain key, or wrench. Your drain may not have crosshairs if it's old and broken.
