Review on SharkBite 22630LF 2 Inch Residential Arrestor by Eric Pruett

Works as advertised! This summer I installed a sprinkler system. Even though it has an expensive vacuum brake/check valve that runs from the main line to the sprinkler system, I had water hammer. Every time the sprinkler valves moved from one area to another, I heard a knock in the attic. At first I thought that squirrels or some animals lived in my attic. I even bought traps. Since the sounds are still audible, I was in the attic when I clearly heard the sound of a waterline. Bought this little gem, installed it in less than 2 minutes. Turned the fountain back on. Turned on the sprinklers while sitting in the attic and cycling through the zones (I can control this from my phone). No more knocking. This little thing is great! A good buy for those who have these problems.
