"Needed baseline data on sewer laterals, rain drains, storm drains and courtyard drains, as well as some drain cleaning in a townhome complex. Service was prompt, communication good, everyone courteous. Received a detailed description of work done and findings at each unit for a very reasonable price."

"I have to say this company impressed me every step of the way. From the first time I called until the job was completed, they we're punctual professional and I waited for nothing. I usually expect to wait for return calls, emails etc. I was always supported when my inquiries were answered within minutes. Everything was seamless. I've had many experiences with terrible customer service and expensive repairs left not feeling like I got my money's worth. Not with Simpson Plumbing. They come highly recommend by me."

Sewer Cleaning FAQs, answered by experts

Yes, rats can come up through drains. They can crawl through basement floor drains, lateral house drains, and roof drains. Installing rat blockers in your drains is the best way to repel rats and prevent them from entering your pipes. These are one-way valves that allow water and waste to flow out but keep rats from getting in.

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.

Bleach isn’t likely to help unclog a sewer line. Bleach isn’t useful in this situation because it won’t dissolve the grime and debris in the clog. Instead, you want to use ingredients that will have a chemical reaction to clear out the buildup, like vinegar or salt and baking soda.

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.

There are several homemade solutions for clearing a clogged sink that don’t involve pouring harsh chemicals down your drain. Start by pouring hot (but not boiling) water down the drain. This can help dissolve and flush away grease and gunk. A splash of dish soap down the drain can also cut through fat and make it easier to clear the drain. For a more stubborn blockage, grab a plunger and give it a few firm pumps to dislodge the clog.
