On a finished home where all the plumbing fixtures are set and in use, Sewer Gas Leaks can be very hard to find. One way to narrow down where the sewer gas is coming from and potentially pinpoint the leak is to do a Smoke Test on the DWV piping system. DWV is an acronym for Drain, Waste, and Vent.
The Drain, Waste & Vent piping in your home is all connected to make a functional system for carrying the solids and wastewater to the sewer and letting sewer gas escape via the venting through the roof. Occasionally there is a breach in the DWV system that causes gas to enter back into the home. Smoke testing the DWV system is the quickest & most economical way to perform leak detection and to narrow these leaks down.
Smoke Testing is a method of blowing non-toxic smoke into the DWV system creating pressure in the system in an attempt for smoke to exit the system where the leak is. This is an effective way of finding the leak or breach in the DWV system however the drawback with this method is it creates an odor in the home but dissipates in a couple of hours.
Our licensed and insured plumbing specialists are highly trained in using state of the art diagnostic equipment to diagnose your Smoke Test on the DWV (for sewer gas/leak detection) issues. Call us today at 502-271-1331, Schedule Online or Request an Estimate!

Can’t say enough good things about ASI’s professionalism and honesty. We purchased a property and several plumbing issues were discovered during the home inspection that needed to be resolved. We sought estimates from other companies but ASI was by far the most timely and transparent provider. They gave us an instant quote that was actually under what we expected to pay. We accepted their estimate and are EXTREMELY glad that we did. They arrived ahead of schedule the day of the repairs and were super communicative in terms of ETA. Loukas came in and got straight to work. He explained everything that he was doing, demonstrated the new sump pump and explained how it worked. One of the issues listed on the inspectors report actually didn’t need repair. He could have easily moved forward with the unnecessary repair and charged me for it. But he didn’t. Was completely honest and transparent. Did an amazing job. I had another issue come up a few days later. Need to replace the shut off valve on my furnace. The company dispatched Alan to help resolve the issue and his service was also AMAZING. Showed up on time, explained everything and cleaned up his work area after everything was done. Tested all the gas lines, which saved me from facing issues from the local gas company technicians. Can’t recommend them enough. Will be using them for all of my plumbing needs moving forward.

Technician called before appointment with a rough estimate. Called prior to arrival. Was on time and very efficient. Repaired the water heater when another company said it needed to be replaced. Absolutely will use ASI plumbing again.

Nathan was my plumber and he was excellent. He got to my house about 15 minutes early so I didn’t have to wait until the last hour of my scheduled appointment. Very friendly and knowledgeable. He was adequately prepared and fixed the bathtub leak in a reasonable time. ASI quoted me the cost of repair over the phone after I filled out an online request (included pictures) within 15 minutes. I was worked into the schedule the following day. I thought that it would probably be more expensive than quoted but to my shock it was the exact amount. I cannot tell you how wonderful and anxiety free it is having a contractor not lie, be late, go over the estimated price or a complete idiot in plumbing repairs. A++ Well done!

Great experience from beginning to end on instant hot water heater. Scheduled for a day later and they called with an opening that day. Ended up being a bigger job. Won’t go anywhere else!
