Why Is My Water Pressure Low?

Low pressure has a short list of real causes. Here's how to narrow it down before calling anyone.

Check these first

First, isolate the problem: is it one fixture or the whole house? One faucet usually means a clogged aerator or worn cartridge. Whole-house drops mean checking the pressure regulator setting, confirming the main shutoff valve is fully open, and asking neighbors whether they've noticed the same thing — sometimes it's the city supply, not your home.

When it's a bigger problem

If those checks come up clean, the cause is usually one of three things: corroded galvanized pipe narrowing from the inside, a failing pressure tank on a well system, or a hidden leak quietly stealing pressure from the whole system.

When to Call a Pro

If pressure dropped gradually over months or years across the whole house, that's usually pipe corrosion — not a quick fix, but a repipe solves it for good.

FAQ

Why is pressure low in just one faucet?

Almost always a clogged aerator or a failing cartridge in that fixture — a 10-minute fix, not a system problem.

Could a leak cause low pressure?

Yes — a leak anywhere in the system steals pressure from every fixture. Check your water meter for movement when everything’s off.

Will a booster pump fix low pressure?

Only if the cause is supply-side (well or city pressure), not internal pipe corrosion. We diagnose before recommending one.
