Don’t Let Plumbing Smells Be an Uninvited Guest This Thanksgiving

Save Time, Call Prime!

For many of us, thoughts of Thanksgiving evoke memories of delicious aromas wafting through our homes as we gather with friends and family. The scent of turkey roasting and other tantalizing smells signals togetherness, delectable food, and the onset of the festive season.

However, when the scents filling your home are less-than-pleasant, particularly those originating from your plumbing, it’s crucial to quickly pinpoint and address the cause to ensure your living environment is both healthy and great smelling!

Plumbing Smells & What They Mean

  • Sewage: As organic household waste decomposes, it emits a mix of foul-smelling toxic and nontoxic gasses. Drains typically have a trap to prevent sewer gasses from escaping from the drain into your home. Over time, the water within your traps will evaporate causing the trap to dry out and lose its seal, especially in drains that are not frequently used, such as in a guest bathroom or seasonal home. If a p-trap loses its seal, sewer gas can flow up and out of the drain. Exposure to sewer gas can cause nausea, dizziness, fatigue, memory problems, and general confusion. Experts also warn that sewer gas is highly flammable, increasing the risk of explosion or fire.

Periodically pour water down seldom-used drains to prevent the p-trap from drying out and to maintain an airtight seal. If needed, a Prime professional plumber can quickly install a new p-trap and keep those nasty sewer gasses from entering your home.

  • Rotten eggs: A pungent, foul odor resembling rotten eggs or sewage is a red flag that can signal a gas leak. The unpleasant sulfuric smell may indicate an emergency, as a gas leak can result in fire, carbon monoxide poisoning, or other serious illness. If you detect a rotten egg smell in your home, immediately contact your gas company and vacate the house. Don’t reenter your home until the gas company rules out a gas leak.

If it’s not a gas leak, a broken pipe or an electrical system issue may be causing the sulfuric odor. If you only detect this particular smell when running water, it may indicate an issue with your water heater. Contact a professional to pinpoint the problem. Always have functioning carbon monoxide detectors in your home to safeguard your loved ones.

  • Chemicals: Sharp, chemical odors could mean that hazardous materials or substances have been improperly disposed of, or there may be a serious issue with your water supply.
  • Musty or wet earth odors: Often indicative of mold or mildew, this scent suggests that there is persistent moisture in areas that should be dry. Mold and mildew most commonly appear in kitchens, bathrooms, and laundry rooms where warm, damp conditions encourage growth — such as behind toilets, under sinks, or in poorly ventilated, humid areas. Mold spores can cause serious respiratory and other health problems. Sneezing, coughing, headaches, fatigue, or worsening allergies or asthma, may be signs that you have mold.

How To Avoid Unwanted Plumbing Odors

As discussed, odors emanating from our home’s plumbing can signal the presence of toxic gasses that can harm the health of your family and may increase the risk of fire, explosion, or asphyxiation.

Of course, we’d all prefer to keep our homes safe and odor-free. The following tips will help you avoid, or at least minimize the risk, of unwanted plumbing odors.

  • Be mindful of what goes down your drain. Never discard oil, food waste (even in your garbage disposal), or paper products, as these can cause unpleasant smells and may harm your pipes.
  • Periodic flushing of your drains with hot water, small amounts of vinegar, and baking soda can keep things moving smoothly. The experts at Prime Plumbing strongly advise against the use of chemical drain cleaners which can severely damage your pipes.
  • Conduct regular checks of visible pipes for signs of leaks, condensation, or corrosion.
  • An annual inspection by a Prime or other professional plumber can be invaluable for uncovering hidden plumbing issues and preventing future problems.
  • If you do smell an unpleasant odor in your drainage system, contact a professional plumber to diagnose and remedy the problem.

Trust your nose! Sniff out where the noxious odor is coming from and what it smells like — sewer stink, rotten eggs, chemicals, or wet earth, and describe the smell to your Prime plumbing expert. Prime Plumbing is always here to ensure you and your family are safe and your home is healthy. Save time, call Prime!

All of us at Prime Plumbing wish you a Thanksgiving filled with delightful aromas and joyful moments with loved ones. May your holiday be warm, fragrant, and full of gratitude.

    It's taken me a while to write a review with two young kids- but i wanted to make sure i shared what a wonderful experience we had using Prime Plumbing. We had a sewer line back up in our basement (yuck) and i had multiple plumbers come out and give quotes on digging up and replacing our old copper sewer line with pvc. Tim impressed me from day 1 and stood out amongst the others with his confidence and expertise in what our options were, what to expect from the whole process, etc. They dug up our lawn (8 ft deep, approx 40 ft long) and i am so happy with how they managed to put it all back together. I can't take a current picture of it now because our yard is covered with snow, but 2 months later you'd hardly be able to tell we had a trench dug up. We were quoted around the same price by another company who said they would need to tear out our retaining brick wall and also said they'd leave piles of dirt, and that the grass seed/hay would cost extra!! Also, Prime managed to get this all done in 1 day. Not to mention, we got to keep our beautiful maple tree! This is the only tree in our yard and our kids love swinging on it so while i was ready to give it up if need be, i was going to be a little devastated. Only a few days after my initial consultation with Tim, we had a brand new sewer line! We are so happy we found a good, reliable & trustworthy company to make us feel better about forking over a pretty penny on a hidden (but very crucial) repair. Thank you Prime Plumbing!

    Great work! Very nice service; fixed our water heater issue and had us back up and running in no time. The service provided by Ernie and Hayleigh was very professional and courteous.

    [UPDATE: RESOLVED] I'm updating this review to reflect that Prime Plumbing has owned up to the situation and made it right. Once my new toilet arrived, they returned and completed the installation at no additional cost to me. The 5-stars are for Ernie and Hailey who handled the final install, and they were a complete 180 from my previous experience. They were awesome, professional, and sociable. You could tell they actually enjoy their work and take pride in it. They got the job done right. While the road to get here was frustrating, I appreciate the company standing by their work and sending the right team to finish the job. [OLD REVIEW] I hired Prime Plumbing to fix a toilet leak, and after 4 visits and hundreds of dollars, I had to do their work for them. Here is the timeline of negligence: March 27, 2025 (Invoice #90891): I paid an $89 trip fee to have a technician come out. He did a visual glance without even lifting the toilet and told me "nothing was wrong." The leak continued. Nov 1, 2025 (Invoice #97073): I paid $634.56 for a "Toilet Pull and Reset" (Service Code TUR-110). The invoice states they would "prepare the mounting system." They claimed the issue was a decayed wax seal (after initially guessing "condensation"). They did not inspect the toilet for cracks, but they didn't miss the opportunity to try and upsell me a new water heater. The leak continued. Nov 24, 2025 (Return Call): When they came back, the technician tried to blame "condensation" again and claimed "these electric toilets aren't reliable", again making excuses. He replaced the wax seal again without inspecting the toilet. Nov 30, 2025: The leak returned. Before booking them again, I spent 1.5 hours doing what they should've done. I replicated the leak and reached behind the toilet to feel the failure point. I felt the wax ring and—crucially—I felt plastic obstructing the seal. Dec 1, 2025 (Invoice #97936 Return Call): The tech arrived, and I told him what I found. He told me, "That's impossible... Show me how you did it. Show me this magic." I had to literally get on the floor and prove it to him. I ABSOLUTELY should not have had to do his job for him. He then complained about how he "can't keep coming out here" and is "losing money." Completely unprofessional. He finally pulls the toilet up, actually inspects it, and finds a crack. He sounded gleeful showing it to me, acting like this vindicated his misdiagnosis. He then told me I need to pay a third time to have a new toilet installed. THE REALITY: Did he inspect it the first time? If he did and saw no crack, then he caused the crack by mishandling the toilet. Did he not inspect it? Then the crack was there the whole time, and due to his incompetence, he misdiagnosed the issue for months while taking my money. I paid premium pricing for a professional diagnosis and fix. Instead, I got laziness in March, incompetence in November, disrespect in December, and an issue that wasn't fixed. Now they want more money to fix the issue they likely caused. Avoid this company unless you want to do the plumbing yourself after paying the bill. When my new toilet arrives, I will be reaching out to them to complete the install of the toilet at no additional cost to myself (I am not asking for a refund on the cost of a toilet, just want them to install it properly.) Otherwise, this is definitely going to be a complaint to the MHIC.

    Ernie and Hailey are absolute legends! I cannot say enough good things about Ernie and Hailey! I hired them to install a new toilet, and they turned what is usually a mundane maintenance appointment into a genuinely great experience. From the moment they arrived, the service was top-tier. They were incredibly professional and got the installation done flawlessly, but what really stood out was their attitude. They were sociable, friendly, and you could tell they actually have fun on the job. They have a great dynamic and brought such positive energy into my home while working. It is rare to find a team that combines expert workmanship with such a great "vibe." If you need plumbing work done and want it done right by good people, ask for Ernie and Hailey. 10/10 would recommend!
