Low water pressure on a well usually comes from one of five things: a clogged sediment filter, a pressure switch set too low, a waterlogged pressure tank, a leak between the well and the house, or a worn pump or falling water level. Watch the pressure gauge while water runs. How it behaves points to the cause.
Water Well Drilling Weatherford diagnoses low water pressure on well systems across Parker County. The pressure gauge next to your tank is the best diagnostic tool you own. Open a tap in the house, then watch the gauge and listen to the pump for a couple of minutes.
What the gauge tells you
| What you see | Most likely cause |
|---|---|
| Gauge reads normal (e.g., 40–60 psi) but one fixture is weak | A clogged aerator, showerhead or fixture valve |
| Gauge normal, whole house weak | A clogged sediment or whole-house filter, or a partly closed valve |
| Pressure drops fast and the pump starts every few seconds | A waterlogged pressure tank (lost air charge or failed bladder) |
| Pump runs a long time and barely reaches cut-out | A worn pump, a leak in the drop pipe, or a falling water level |
| Pump runs constantly, yard wet between well and house | A broken line |
| Pressure fine, then fades during long showers or irrigation | The well or pump can’t keep up with demand |
The cheap fixes first
- Sediment filter. Parker County water carries iron and grit, and cartridge filters clog. If the pressure after the filter is lower than before it, change the cartridge.
- Switch setting. A 30/50 switch gives lower pressure than 40/60. The setting can be raised if the pump has the capacity, but the tank’s pre-charge must be reset to 2 psi below the new cut-in.
- Sensing port. The small tube under the pressure switch clogs with sediment, making the switch act erratically. Cleaning it or replacing the switch is a $150–$300 job.
When it’s the tank
If pressure falls quickly and the pump starts every few seconds, the tank has lost its air cushion. That’s more than a comfort problem. Submersible motors need at least a minute of run time per start. See signs of a bad pressure tank and pressure tank replacement cost.
When it’s the pump or the well
A pump that runs long and struggles to reach cut-out pressure is either worn, losing water through a split drop pipe, or pulling from a water level that has dropped toward the intake. Near Weatherford, new wells finish with water about 110 ft down. Around Aledo it’s closer to 176 ft, and in dry summers the level falls while the pump runs. We check amp draw and measure the water level before recommending a new pump. Sometimes lowering the existing pump or adding a storage tank is the real fix.
When to stop and call
If the pump runs continuously without reaching cut-out, turn the breaker off and call. That’s how pumps overheat. For the rest, a daytime service call is fine. See well pump repair.
Bottom line
Check the filter and the gauge first. They explain most low-pressure complaints and cost little to fix. If the gauge won't reach the cut-out pressure, or the pump runs constantly, have the pump and water level checked before the motor pays the price.
