Installing a WaterCop and now I have dripping backflow preventer
I installed a device called a WaterCop yesterday. Basically, this is a device that you install by cutting into the main water line just after the meter. The device is a motorized shut off valve. When the main unit receives a signal from one of the wireless sensors, it shuts off the main water valve limiting the damage by water. Several hours later I noticed water dripping from the Backflow preventer valve. In the reading I have tried to do online, this is not an uncommon thing to happen when the pressure is lowered going to the furnace. My questions are these. Was there a way to have prevented this? Should I have shut off the boiler during the time (45 mins) that I was doing this work? Now that it is leaking, do I need to replace it? I purchased another one to swap out ( union fittings so it won't be difficult) but wondered if this will clear itself and stop dripping? Was this caused by the interruption of the water pressure and then when the water was turned on, it sent debris to the Backflow preventer causing this problem? Thanks for any help you can provide..
