1 - Do you guys have a unit specifically used for sewage extraction, and how do you clean it up afterwards? 2 - Does anyone use PAPR respirators, and do they eliminate the smell? 3 - What percentage of your calls are for sewage? My son and I are starting a water damage business but neither one of us want to do sewage losses. Just too hazardous imo. But, I would hate to turn down work from someone that is also sending us cat 1 and 2 losses. Comments please.
