"Perfect! I called Western Rooter the AM my disposal went out. They were at the house the same day, at the time they stated they would arrive. The work was done efficiently and professionally and completed within an hour. I have called on Western Rooter for many years for various plumbing needs (clogged drains, replace water-heater, replace main water line, etc.) and have always had great, timely service at reasonable $$$."

"Hire them! Paul came out his with his partner and gave me the lowest quote I could find to hydro jet my area drain in my concrete driveway! Not only that, they came first thing in the morning like I wanted them to, saw the problem, cleared the drains out, and the cleaned up after themselves. They are true professionals who don’t give up on a job and make sure you get the problem 100% fixed. I would definitely recommend them for any hydrojetting service you may need."

"Daniel responded to my request for a quote very quickly and then came out and diagnosed the problem same day. He was very respectful and even took his boots off as he came inside so that he didn’t tack any dirt into the house. He was able to fix the faucet, clean up, and get the water turned back on with in a couple of hours, all for a very reasonable price. Will definitely use his serviced again."

Drain Cleaning FAQs, answered by experts

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. 

The P-trap (or S-trap in older homes) under your shower is designed to prevent sewer gas from coming back up, so you shouldn’t normally experience foul odors coming from your shower drain. If you do, the vent stack that introduces air into your plumbing system may be clogged, or you may have a more severe sewer main blockage. In either case, hire a plumber to fix the issue for you.

Main sewer lines can clog for several reasons. For example, if you regularly dump oil or grease down your drain, it could eventually block your line. Sometimes, tree roots can penetrate and grow inside old sewer pipes, creating a major blockage. Flushing bulky items (like paper towels, diapers, or baby wipes) can also clog your plumbing system.

There are several ways to tell if your gutter downspout drain is backed up. The most obvious sign is when you see water flowing over your gutter edges. This can occur during everything from light rain to a rainstorm. Additional signs can include peeling paint around your downspout, visible dirt around your downspout, and moisture on the side of the house. If you're having ongoing problems with clogs caused by a poorly designed or worn-out gutter system, consider getting a quote for gutter replacement cost.

While there is no specific “best” method to clear hair out of a drain, several options work well. Using a combination of baking soda and vinegar to dissolve the hair clog is a great and easy way to help clear the drain. Drain snakes are also effective for more severe clog buildups.
