Symptoms & Causes
Short‑Cycling
Failed tank bladder or incorrect pre‑charge causes the pump to turn on/off rapidly. We set pressure correctly and replace components.
Low Pressure
Clogged filters, failing pressure switch, or scaling in galvanized sections restrict flow. We test and correct each step.
Leaks
Tank fittings, relief valves, or the tank body. If the shell leaks, replacement is recommended for safety.
No Water
Well pump or control issue; we diagnose pressure switch, control box, and verify pump operation.
Our Repair & Setup
- 1.Safety and isolation; verify voltage and relieve pressure.
- 2.Replace pressure switch, gauge, relief as needed; set cut‑in/cut‑out properly (e.g., 40/60 psi).
- 3.Set tank pre‑charge 2 psi below cut‑in for correct draw‑down; confirm bladder integrity.
- 4.Flow test fixtures and check for leaks; review maintenance schedule.
Pressure Settings & Pre‑Charge Explained
Your pressure switch has two setpoints: cut‑in and cut‑out (commonly 40/60 psi). The tank’s air pre‑charge should be 2 psi below cut‑in so the pump has time to fill the tank before reaching cutoff. Incorrect pre‑charge causes short‑cycling and premature pump wear.
- Measure pre‑charge with water off and the tank fully drained
- Label switch settings and pre‑charge for quick future checks
- Replace aging switches that chatter or arc
Costs & Timelines
We price by tank size, control parts, and access. Most repairs complete same visit; tank replacements vary by size and plumbing configuration.
When Replacement Is Safer
If the shell is rusted through, the bladder has ruptured repeatedly, or the tank is undersized for your pump, replacement prevents ongoing issues and protects the pump. We size the new tank for proper draw‑down and label settings for easy maintenance.
Maintenance Tips
- Check tank pressure annually with water off and tank drained
- Keep a clear area around the tank and control box for ventilation
- Install sediment/iron filtration where tests indicate problems
- Label the cut‑in/cut‑out and pre‑charge so settings are easy to verify
FAQs
What pressure should my tank be?
Set pre‑charge 2 psi below the switch cut‑in (e.g., 38 psi for 40/60). We set and label it during service.
Why is the pump short‑cycling?
Loss of air charge or a failed bladder reduces draw‑down. We correct pre‑charge or recommend tank replacement when the bladder fails.
Do you work on iron or sulfur water issues?
Yes. We can test and recommend filtration options to protect fixtures and piping.
