No, well pumps don't need a pressure tank to function, but it is highly recommended.
Here's why a pressure tank is beneficial for your well pump system:
-
Extends Pump Lifespan: Well pumps are not designed for frequent, short bursts of operation. A pressure tank reduces the number of times the pump cycles on and off, minimizing wear and tear and significantly extending its lifespan.
-
Prevents Water Cycling: Without a pressure tank, the pump will turn on every time a faucet is opened, even for a small amount of water. This rapid on-off cycling, known as water cycling or short cycling, can damage the pump motor and lead to premature failure.
-
Provides Consistent Water Pressure: A pressure tank stores water under pressure, ensuring a more consistent and stable water supply to your fixtures. This prevents fluctuations in water pressure that can be annoying and potentially damaging to appliances.
-
Reduces Energy Consumption: By reducing the frequency of pump starts, a pressure tank helps lower energy consumption and saves you money on your electricity bill.
Think of it like this: the pressure tank acts as a buffer, storing water and providing it on demand, so the pump doesn't have to work constantly. While a pump can technically run without one, doing so dramatically shortens its life and introduces other potential problems.
