"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."

"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."

"Andrew is very professional and does clean work, which is important to me. He responds quickly and came to our home in a timely manner because we could not use our sprinkler system during August in the desert. I can no longer do these repairs myself and am so grateful for his help. He explained everything to me beforehand and when he was finished with his work. I will definitely call on Andrew with any plumbing needs."

Drain Cleaning FAQs, answered by experts

To keep window wells from filling up with water, you need to stay on top of maintenance. Remove debris as it fills up, and regularly loosen the gravel at the base if it’s become compacted. You can also reslope your yard to make sure water flows away from the window well (and your home’s foundation), and you can even install a window well cover to prevent debris from building up. Installing an actual drainpipe at the base of the well can also prevent window well drainage problems.

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.

Liquid drain cleaners are harsh chemicals that can erode your pipes. To treat a slow drain or for preventative maintenance, pour hot water down the drain to break up gunk and help move it along. Make sure the water isn’t boiling hot (keep it under 140 degrees Fahrenheit) if you have plastic pipes. However, you’ll need to pull the clog out for bigger backups. 

Clogs in a sprinkler valve can be caused by various factors, including debris in the water supply, sediment buildup inside the valve, or damage to the diaphragm. Debris and sediment can accumulate over time, obstructing the valve's passages and impeding water flow. Damaged diaphragms may develop tears or holes, leading to blockages and affecting the valve's ability to open or close properly. Regular maintenance and cleaning can help prevent and address these issues, ensuring your sprinkler valve operates smoothly.

Baking soda and vinegar is a great solution for cleaning your sink drain; in fact, it’s our preferred method. Here’s how to unclog your drain with baking soda and vinegar: Pour in a half cup of baking soda, then 1 cup of white vinegar, and let the two bubble for 15 minutes. Then rinse out with boiling water. This method is much safer than using a chemical drain cleaner gel.
