A pressure tank assembly for use primarily in a plumbing system connected to a well or other water supply system includes a tank containing a bladder and a ring around the bladder in the tank midway between the top and bottom ends thereof. Water is introduced into the ring and discharged into the tank via holes in the bottom of the ring. Water for domestic use is drawn from the top of the tank. Sediment is removed through a drain in the bottom of the tank.
