The process of draining a water well involves several steps to ensure it's done safely and effectively, primarily focusing on turning off the pump, connecting a hose, and opening the necessary valves.
Here's a step-by-step guide on how to drain a water well:
-
Turn Off the Well Pump:
- Locate the breaker switch in your electrical panel that controls the well pump. It's often labeled "Well Pump".
- Turn the breaker to the "Off" position. This prevents the pump from running while you're draining the well, which could damage it.
- Alternatively, if your system has a pump control switch near the well tank, switch that to the "Off" position.
-
Locate the Boiler Drain or Hose Bib:
- Find the boiler drain (also called a hose bib) located near the bottom of the well tank. This is where you'll attach your garden hose.
-
Connect a Garden Hose:
- Attach a standard garden hose to the boiler drain or hose bib.
- Run the other end of the hose to a location outdoors where the water can safely drain away from your house and foundation. Ensure the discharge area is a suitable distance away and doesn't create a hazard (e.g., icy patches in winter).
-
Shut Off the Main Shutoff Valve (Optional but Recommended):
- While not always necessary, shutting off the main shutoff valve (usually located before the pressure tank) prevents backflow and can make the draining process more controlled.
-
Open the Boiler Drain/Hose Bib:
- Carefully open the valve on the boiler drain or hose bib. This will allow the water in the well tank to drain out through the garden hose.
-
Monitor the Draining Process:
- Check the hose periodically to ensure water is flowing smoothly and that there are no leaks.
- Be patient, as it can take some time to drain the entire tank.
-
Addressing Potential Issues (if applicable):
- Air Lock: If water stops flowing but the tank is not empty, an air lock may have formed. Try opening a faucet inside the house to relieve the pressure. You may also need to cycle the pump breaker on and off briefly to prime the pump (exercise extreme caution if doing this and refer to your pump's manual).
- Sediment: Be aware that draining the well tank can stir up sediment. If you notice sediment in your water after refilling, flush your plumbing by running faucets for a few minutes.
Important Considerations:
- Why Drain a Well Tank? Common reasons include maintenance, repairs, or disinfection.
- Consult a Professional: If you are unsure about any step in this process, consult a qualified well service technician.
- Well type: Different well types, like artesian wells, may require different draining methods.
- Disinfection: If draining the well for disinfection purposes, be sure to follow proper disinfection protocols afterward.
