Today we showed up for a complimentary plumbing estimate. Upon inspection the homeowner was having sewer gas seep out into garage and then through the whole house. The vent stack inside the garage had a custom plumbing repair done to it. The kitchen sink and washer drained into this vent stack and was not connected properly. Recommendation- replace 10ft of 4 inch vent pipe, and connect the kitchen with the proper fittings Thank you for choosing comfort experts!
