These guys are the best. Been using their service for years. Recalibration, gauges and assembly's. Sean is a rock star and will always be on my first call list!!!
Item was ship quickly and was in excellent condition
Six star work great I’ll be at it again Thursday
5 star for sure. Just what I needed.
Backflow supply product delivery was right on time as promised. The 845-5 Backflow Test kit offers so much more than other differential test kits. I will continue to order through Backflow Supply.
