"Ryan was perfectly on-time and was a plumbing scholar and a gentleman. We had a simple drain replacement under a new sink. Going to Western saved me at least another day of trying to figure out proper parts and doing the install myself, and it also saved my wife's ears from hearing my salty language."

"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 questions, 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. 

Once you’ve poured the baking soda and vinegar into a drain, you should wait about 10 minutes for the mixture to break down the clog. If you try the baking soda and vinegar method and it doesn't work, you can do it again or try the baking soda and salt trick.

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.

If you have a sink stopper, it can feel more challenging to clean the drain without removing it, but here are a few simple steps:

  • Pour ½ cup baking soda into the drain using a funnel

  • Pour 1 ½ cups vinegar into the drain

  • Close the sink stopper for 15–20 minutes

  • Open the drain

  • Pour 2 cups of boiling water down the drain (be cautious as boiling water can damage some types of pipes)

If the drain isn’t unclogged, repeat the process.

Common drain issues include slow-running drains, whether in a sink or shower, clogged drains, a bad smell, and water backing up into a sink, shower, or bathtub. Causes range from hair, grease, roots, or toilet paper clogging the drainpipes to flooding outside the home, which prevents sewer lines from draining properly.
