Low Well Water Pressure: Troubleshooting Guide
Low pressure on a well system usually comes from something simple, like a clogged filter, before it's the pump or the well. Work from the easiest checks to the hardest.
1. Is it one faucet or the whole house?
If it's one fixture, clean its aerator or showerhead. Mineral buildup is common with well water.
2. Check filters and treatment equipment
A clogged sediment filter, or a softener or iron filter that needs service, can choke flow for the whole house. Bypass it briefly to test.
3. Watch the pressure gauge
Near the pressure tank there's usually a gauge. Run water and watch it. If pressure drops quickly and the pump turns on and off rapidly ("short cycling"), the pressure tank may have lost its air charge or the bladder may have failed.
4. Pressure switch
The pressure switch tells the pump when to start and stop. Contacts can pit and the small tube under it can clog. This involves line-voltage electricity, so turn off power at the breaker before touching it, or call a pro.
5. Pump or well problems
If pressure is low everywhere and the tank and switch seem fine, the pump may be worn, or the well may not be keeping up with demand (for example in drought). These need a licensed well or pump contractor.
When it's also cloudy or smells
If low pressure shows up together with sediment, cloudiness or odor, test the water. See our which water test tool.
Frequently asked questions
Why does my well pump keep turning on and off?
Rapid on/off cycling is often a waterlogged pressure tank or a failed bladder. Have it checked, because short cycling wears out pumps.
Can a filter cause low water pressure?
Yes. A clogged whole-house sediment filter is one of the most common causes.
