What is a Smoke Test?

Have you ever seen smoke coming out of a manhole or the vents in a roof? While this may seem unusual, it’s actually the result of something called smoke test plumbing, a test used to find leaks in sewer pipelines. Let’s discuss what smoke tests do and address some common concerns about them.

What does a smoke test do?

When conducting a smoke test, the technician injects an artificially produced smoke into the pipes, where it will force itself out of any openings in the system. If the pipe system has leaks, the smoke will force itself through the leak and alert the technician to its presence. A system without any leaks will force the smoke out through a nearby manhole cover or home vent.

Common Smoke Testing Questions

Will there be smoke in my house?

This is unlikely, but it is possible that the smoke could enter through improperly installed or damaged plumbing. Although your first reaction to this might be annoyance, the presence of smoke indicates that your home is vulnerable to dangerous sewer gases. Locate one of the smoke testers if there’s smoke in your home.

Is the smoke dangerous?

No, the artificial smoke used is not harmful to you, pets or plants. It isn’t flammable and won’t stain fabrics either, but you should open windows for ventilation to prevent prolonged exposure.

How should I prepare for a smoke test?

Run water through any infrequently used drains (such as an unused guest sink). Although the smoke isn’t harmful, consider placing pets in an area without any plumbing and cracking a window for ventilation if you won’t be at home to attend to them.

Do I have to be home during the test?

You don’t have to be home while the smoke test is conducted, nor do you have to worry about anyone entering your house.

Can my smoke alarm be activated from the smoke?

The artificial smoke may set off your smoke alarm. If it does, open doors and windows to ventilate. Be cautious — call 911 if you’re unsure of the source of the smoke.

Very fast response. Reliable and even let us do some of the work to keep costs down. Really worked with us to sort through alternatives to find the best solution. I have used them about 5 years ago and will certainlycall them again if I ever need anything.

Roberta C.

Very Knowledgeable

I recently had several plumbing leaks repaired and couldn’t be happier with the prompt service I received from Parker and Sons. They are very knowledgeable, friendly, reasonably priced, and do quality work. I would definitely recommend them to my family and everyone. I would trust them to repair any leak in the house.

Stacey C.

Amazing Service!!!

Amazing service!!! Called and came the same day within 2 hrs. Our toilet had to be re-fitted and snaked. They did a beautiful job on the re-fitting and got the large piece of plastic out of the toilet. Will definitely be recommending them to friends and family. Great service, great people, hard to find these days!!!

Shakira C.

Excellent Service!

Excellent Service! We had some work done on our kitchen and Parker and Sons were able to come out to our house and help us with our remodel. Great guys and great service. I would recommend them to anyone needing a plumber service.

Brad B.

Great to Work With

Jim and his guys are great to work with. Had Parker & Sons come out to take a look at an AC unit at one of my rental properties. Unit is in the attic. Had to replace a coil on it and did a great job. Will definitely use again.

Jeff C.

Amazing Staff!

I have referred Parker and Sons to all of my customers and I would not think of referring anybody else. They have been great and very punctual. All of the plumbers and office staff have been amazing!

Miguel B.

Reasonable Prices

I was in good hands today with journeyman plumber Mark Rizley. He remained until all was better than before. He replaced a PRV and improved a mediocre repair recently done by another well known local company. The price remained reasonable despite the extra effort needed for the job. Well done Mark! Parker and Sons will be my first call in the future.

Todd D.

Fantastic Company!

This is a fantastic company with outstanding professionalism, quality of work, and customer service. While their prices are extremely competitive, their work doesn’t feel cheap like some of the companies you can hire of off Craigslist or on a FB yard sale page. This is a reputable company with proven work and licensed, skilled technicians.

Ben A.

Fair Prices & Excellent Work

Have used Parker & Sons 3 different times, once for a huge complex plumbing repair and twice for smaller jobs. Fair prices and excellent work/fast response time every time.
