Wrench felt flimsy and I was unsuccessful loosening the water filter covers.
I called Nova and sheduled a technician to come out and install the new filters I had bought. He had to use two wrenches together and a large mallet to loosen the filter cases. He said I wasn’t the only customer who bought the wrench and couldn’t loosen them.
Nova only charged me the difference between purchasing the three filters for pickup at the warehouse and the Price of filters with installation.
I am very happy with my Nova filter system and their servicing, but not in the cheap plastic wrench.
