Why Is My Well Water Pressure So Low?

Low water pressure from a private well is one of the most common — and most frustrating — problems homeowners deal with. Here are the most common causes, ranked by how often we see them:

• Waterlogged pressure tank — The #1 cause. When the internal bladder fails, the tank fills with water and can't maintain consistent pressure.
• Failing or undersized well pump — A pump that's wearing out produces less flow.
• Clogged sediment filter or water treatment equipment — A clogged filter dramatically restricts flow.
• Pressure switch malfunction — The switch may not activate the pump at the right pressure.
• Partially closed or failed check valve — Causes the system to lose pressure between cycles.
• Low water table or well yield issues — Drought and seasonal changes can reduce well production.
• Leaking or corroded pipes — Underground leaks bleed off pressure.

Step-by-Step Troubleshooting You Can Do Right Now

Step 1: Check Your Pressure Gauge

Normal residential well pressure is 40-60 PSI. Below 30 PSI, something is off. Zero means your pump may not be running — check your breaker.

Step 2: Check the Pressure Tank

Tap on the side of the pressure tank. A properly working tank sounds hollow at the top and solid at the bottom. If the entire tank sounds solid, the bladder has failed.

Step 3: Inspect Filters and Treatment Equipment

A clogged filter can cut flow rate in half. Bypass each piece of equipment one at a time to find the bottleneck.

Step 4: Check the Pressure Switch

Burned or pitted contacts mean the switch isn't activating the pump properly. A new switch is one of the cheapest parts on the system.

Step 5: Monitor for Pump Issues

If your pump runs continuously but pressure stays low, the pump may be worn out. Pump repair requires a professional.

Professional Solutions for Persistent Low Pressure

Pressure Tank Replacement

Most homes need a 20-30 gallon tank minimum. A new pressure tank is a routine, same-day install.

Booster Pump Installation

A booster pump adds pressure between the tank and house. Common for long supply lines or multi-story homes. Quoted after we size the system.

Well Pump Upgrade

Variable speed (constant pressure) pumps maintain steady pressure regardless of demand. They cost more installed but eliminate pressure fluctuations entirely.

When It's DIY vs. When to Call a Pro

DIY-friendly: Replacing sediment filters, adjusting pressure switch, adding air to tank, bypassing treatment equipment.

Call a professional: Tank replacement, pump work, booster pump installation, suspected well yield issues.
