"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

As a preventative measure, hydro jetting should be done every one to two years. However, the best practice is to hydro jet your sewer line once per year. The ideal frequency depends on several factors, including the age and condition of your pipes, how prone they are to clogging, how often the sewer line is used, and the type of waste disposed of in the system. If you frequently experience clogs or are unsure, it's best to ask a licensed plumber for a recommendation specific to your plumbing system.

Regrading your yard can often fix drainage problems. You can also try aerating the lawn to encourage better drainage or install a new drainage system to prevent water from pooling in certain areas.

Yes, pop-up drains commonly get clogged with hair, soap scum, and toothpaste. It is important to know how to properly clean the drain or get professional help to ensure it remains clear and can drain water effectively.

For disposal clogs with standing water, use a sink plunger and place it over the garbage disposal drain. Push the sink plunger up and down the drain about six to eight times before lifting. If the sink drains, the clogged food particles are dislodged from the drain. If there’s still standing water, repeat the steps until the standing water clears out. 

If you’re not using a septic system, problems with your home’s plumbing won’t cause this—it’s a city problem. A large blockage in the municipal sewage lines may cause those lines to back up into your home. This is extremely unpleasant and can be a serious health risk due to bacteria and other contaminants. If this occurs, call a pro (or your city) immediately.
