"**Robert was very calm, cool, and collected!!!! I got a call from my tenant at about 1p on a Sunday afternoon, that her kitchen ceiling was leaking water. I suspected there was a plumbing issue right away, and I reached out to Robert. Instantly, Robert said he would go take a look after he completed his job across town. Heroically, Robert made it there in about 30 mins and discovered the issue was a clogged pipe, and used all his tools in his belt to help me clear the clogged drain issue. Long story short -- he fixed everything before 3p 😮😮😮 Thank you Robert!! You are the man!! I will call you without hesitation moving forward!!!"

French Drains questions, answered by experts

Yes, sewage smells can originate from a floor drain. If the P-Trap in the floor drain dries out or if there's a clog or other issue in the plumbing system, sewer gasses can escape through the drain, causing nasty odors. Regularly pouring water into the drain helps maintain the water seal and prevent those smells, but if the smell persists, you should have a plumbing professional inspect the drain for potential problems.

In some cases, operating a snake can damage your drain and pipes. This depends on the overall condition of your pipes and how gently you operate the auger. For instance, older galvanized pipes covered in zinc are susceptible to scratches when using a drain snake. Additionally, it’s common for newbies to apply too much force when extending the snake, leading to scratches and related damage. You can also crack the porcelain with an electric auger if you’re snaking a toilet drain. If you’re using a manual snake or auger, the risk is minimal.

There are many things that could cause your basement floor drain to back up. One significant cause of a drainage backup is flushing non-flushable items, such as wipes, paper towels, and facial tissue. Other causes of a backed-up basement floor drain include tree roots impeding the drain pipe or an accumulation of hair, oil, and grease. 

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.

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.
