"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."

"Wes @ Rapid Rescue Rooter & Plumbing did an amazing job fixing our plumbing issues and even gave us advice on how to properly care for our drains and system to avoid problems in the future. Very, much appreciated!! Wes was quick to return our call and schedule an appointment that worked best for us. I also scheduled for work to be done at my parent’s home, knowing they would be in knowledgeable, trustworthy hands! He is definitely highly recommended! Thanks so much Wes!"

"Christian from McLay Services showed up within the agreed time frame to install a new kitchen faucet and fix a leak in one of my bathtubs. He did a great job. Faucet was installed within 20 to 25 minutes. He also fixed a leak in my bathtub in the Master bathroom and installed new a new drain and spout. He was neat and clean in his work and answered any questions that I had. Very good plumber. I would recommend McLay Services to anyone!!"

Drain Pipe Installation questions, answered by experts

Chemical drain cleaners can work to clear clogs in pipes, but their use should be approached with caution. These harsh chemicals can damage pipes over time, and they can also harm the environment. Use them sparingly and consider alternative methods such as using a plunger or a drain snake. If you have concerns about a persistent clog, it's best to consult a professional who can safely and effectively address the issue without causing further damage to your plumbing system.

If you want to avoid using a snake to unclog a drain, or if you don’t have one, try vinegar and baking soda. Pour 1 cup of baking soda down the drain, followed by 1 cup of white vinegar. Wait for 15 minutes, and then run hot water (but not boiling water) down the drain to see if the clog is clear. Repeat multiple times as needed.

Although linear drains allow water to flow quickly and efficiently, they tend to clog more easily than traditional drains. Linear drains are flush with the shower floor, allowing soap scum and hair to potentially build up. They’re also longer than other drains, allowing for more space to let debris fall into the drainpipe. 

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.

No, you should not see water in a sewer cleanout. If you do, it could indicate that you have a block or leak in your main sewer line—which can cause sewage to back up inside your home and potentially flood your yard. Your best bet is to call a local sewer cleaner if you notice any water or sewage around your cleanout.
