Although the pump is 1 year old, the fresh water tank is 17 years old. I have no idea what "quality" of water has been in the tank during those years. I just expect the check valve in the pump to clog with calcium/grit on a semi-regular basis. The inline filter ahead of the pump is not a fine mesh. I view the $15 add-on check valve as an item I can easily replace in the future. I think of it as an improvement.
