No water pressure: the check, the cause, and the cost

No water pressure, or a pump that will not stop cycling, is a common call, and the fix is often cheaper than a new pump. Most repairs run $150 to $500.

Check this first (five minutes)

Check the fresh tank level. An empty or very low tank is the single most common cause of no pressure, and it is free to rule out.
Confirm the pump switch is on, and listen to how it sounds. A pump running dry (no water in the line) usually sounds higher-pitched or strained compared to normal operation.
Check for a leak. If the pump cycles on and off with every faucet closed, water is escaping somewhere in the system and the pressure switch is chasing it.
Check the inlet strainer if you know where it is. A clogged strainer restricts flow and can look like a failed pump.
If pressure is weak rather than absent, note whether it is weak everywhere or only at one fixture, which points toward the pump versus a specific clogged fixture.

What is usually wrong

What you find	Likely cause	Fix and cost
Tank is empty or very low	No fault, needs filling	No repair needed
Pump runs, no water, tank has water	Lost prime or clogged strainer	$150 to $350
Pump cycles constantly with faucets closed	Leak somewhere in the system	Find and repair: $150 to $400
Pump sounds strained, weak pressure everywhere	Failing pump	Replacement: $250 to $500
Weak pressure at one fixture only	Clogged aerator or fixture-specific issue	$75 to $200
No sound from the pump at all	Electrical fault, fuse, or switch	$150 to $350

Why this happens after a Montgomery County storage-yard sit

A rig that sits for months has a pump that has not run, fittings that have not been checked, and a strainer that can quietly clog before the next trip. Catching a slow leak early matters more here than it might seem, since an undetected drip inside a wall cavity in Gulf Coast humidity is a setup for the same kind of mold and water damage that a roof leak causes, just from the inside.

What to expect on the call

Tell us the tank level, whether the pump makes noise, and whether pressure is weak or completely absent. We work on site across Conroe, Montgomery, Willis, The Woodlands, Magnolia, New Caney, and Huntsville. The plumbing and water heater repair service page covers this in more depth.

Frequently Asked Questions

The pump runs but no water comes out. What is that?

Usually the fresh tank is empty or the pump has lost its prime. Check the tank level first, then listen to whether the pump sounds like it is straining against no water (a higher-pitched whine) versus running normally.

The pump cycles on and off constantly even with a faucet closed. Why?

That is a leak somewhere in the system, even a small one, that keeps triggering the pump's pressure switch. It could be a fitting, a line, or a fixture. It is worth finding quickly since a slow leak inside a wall or cabinet can cause real damage over time.

How much does a water pump replacement cost?

$250 to $500 installed. Before replacing it, we check the strainer and the tank level, since a clogged strainer or a low tank can mimic a failed pump for a fraction of the cost.

Is low pressure the same problem as no pressure?

Related but different. No pressure at all usually means tank, pump, or a major blockage. Weak-but-present pressure more often means a partially clogged strainer, a failing pump, or a regulator issue, and we check for those specifically.
