Last evening I made a temporary Mickey Mouse repair to hold me over for the night. Take my advice and hire this company. They're licensed and insured. Attempting to fix fire system pvc can be a tremendous liability on yourself or a plumber that's not properly licensed and insured. It's a costly mistake to attempt this repair on your own or with a plumber that doesn't have proper qualifications. When all was said and done, this repair took approximately and hour or more. Sterling drained the whole system and used a shopvac to remove approximately 5-10 gallons of residual water sitting in a trap somewhere below. It's essential that the contractor dries out the water so that the glue has time to set and cure for 24 hours. This was a good learning experience for myself because I'm an hvac contractor and I deal with some domestic pvc plumbing (low pressure hvac condensation). I'm glad I didn't attempt the repair myself because if I would have flooded my house a few weeks down the line, my wife wouldn't have been happy. 5 stars for service 5 stars for repair 5 stars for pricing
