TL;DR
A pressure tank is the captive-air storage vessel on a private well system that uses a compressed air cushion—usually behind a butyl diaphragm or bladder—to push water into the house between pump cycles. By storing several gallons of drawdown, it spares the pump from starting at every faucet opening, the main thing that wears out submersible motors.
What it means
A pressure tank is the captive-air storage vessel on a private well system that uses a compressed air cushion—usually behind a butyl diaphragm or bladder—to push water into the house between pump cycles. By storing several gallons of drawdown, it spares the pump from starting at every faucet opening, the main thing that wears out submersible motors. Sizes run from 20 to 120 gallons nominal, and a waterlogged unit shows up as rapid pump cycling.
