You mean like the contractor installed it? Mine was simply installed hanging on the 3/4 CPVC. So as long as the bladder is still good it simply needs to be refilled with air. They should be checked from time to time and refilled. You need to know what your water pressure is for your home. You would need a gauge to test your water pressure and then based on the tanks recommendations, fill the tank to the correct pressure. A replacement tank is about $50 the gauge and adapter another $30 but now you get rid of the yearly service call. A little time on the internet can save a lot of dollars. It depends on how handy you are and if you have any tools.
