You know that tall, blue propane tank next to some houses? A pressure tank looks similar but holds about forty gallons of water and a pocket of compressed air. The air pushes the water through your pipes so you don’t need the pump humming every time you splash a drop.
An Illustrated Guide to Residential Water Well Systems
Here’s a funny thing—if you ever hear your well pump turning on in the middle of the night, you’re probably “water-poor.” The tank might have a leaky air bladder, or you’ve got a slow-dripping faucet that’s tricking the pump into thinking you just hosted a water balloon fight. That’s when your electric bill gets grumpy.
What About Bad Water?
Your well water comes straight from the earth, which means it can taste like a mineral bath. Some wells pump out water that’s high in iron, turning your bathtub orange. Others have a pinch of sulfur, making your morning coffee smell like a hard-boiled egg (not ideal).
To fix this, you add a water softener or a filtration system. These live in a separate barrel next to your pressure tank. They use salt or a special resin to swap out the nasty minerals for nice, friendly ones. It’s basically a chemistry spa day for every drop that comes into your sink.
