Low Water Pressure From a Well: What to Check
Weak showers and slow taps on a private well: how to tell a switch setting or clogged filter from a failing pump or a dropping water level, and what each fix costs.
Start with the gauge
Find the pressure gauge near the tank. If pressure rises and falls normally but never reaches a useful level, the switch setting or the pump is the suspect. If the gauge is fine but one fixture is weak, the problem is in that fixture or a filter, not the well.
Common causes, cheapest first
- A clogged sediment filter or water softener resin bed, the most common and cheapest fix.
- A pressure switch set low or worn; Angi puts a new switch at $120 to $175 installed.
- A waterlogged pressure tank, which also causes short cycling.
- A leak in the buried line between the well and the house.
- A worn pump or a pump set too high in a well whose water level has dropped in drought.
When it is the well
Pressure that falls off during long showers or irrigation, air spitting from taps, or sand in the water point to the well itself: a dropping water level or a worn pump. A contractor can measure the water level and pump output. In deep wells the fix may be lowering the pump, which adds drop pipe and wire at about $1 to $3 per foot each (The Well Guide).
Constant-pressure systems
A variable-speed, constant-pressure system holds pressure steady; Angi lists $1,300 to $4,000. Some groundwater districts have rules for these drives, so check our state guides for Florida, North Carolina and Texas first.
