Water pump onslaught: why it’s driving me crazy
What To Know
- This can be caused by a faulty pressure switch, a problem with the pressure tank, or a restriction in the water line.
- Air in the water lines can cause the pump to cycle on and off as it tries to expel the air.
- If you’ve checked for leaks, tested the pressure switch, drained the pressure tank, cleaned the filters, and bled the air from the lines, but your water pump still keeps going on, it’s time to call a licensed plumber.
A water pump is a crucial component in any plumbing system, ensuring that water flows smoothly throughout your home. However, when your water pump starts acting up and turns on excessively, it can be a source of frustration and concern. If you’re wondering “why does my water pump keep going on,” this comprehensive guide will explore the potential causes and provide solutions to help you restore normalcy.
Common Causes of Excessive Water Pump Activation
1. Leaky Faucets or Fixtures
Leaking faucets or fixtures can cause a continuous flow of water, which triggers the water pump to turn on frequently to maintain pressure. Inspect all faucets, showerheads, and toilets for leaks and repair them promptly.
2. Running Toilets
A running toilet can also cause the water pump to turn on repeatedly. Check the flapper valve and fill valve to ensure they are working correctly. If necessary, replace the worn-out components.
3. Water Pressure Fluctuations
Sudden drops or increases in water pressure can cause the water pump to cycle on and off. This can be caused by a faulty pressure switch, a problem with the pressure tank, or a restriction in the water line.
4. Faulty Pressure Switch
The pressure switch monitors water pressure and activates the pump when it drops below a certain level. A malfunctioning pressure switch can cause the pump to turn on too frequently or not at all.
5. Waterlogged Pressure Tank
The pressure tank stores pressurized water for consistent flow. If the tank becomes waterlogged, it can’t maintain pressure, leading to excessive pump activation. Check the tank’s air valve and drain any excess water.
6. Clogged or Dirty Filters
Clogged or dirty filters can restrict water flow, causing the pump to work harder and turn on more often. Regularly clean or replace the filters in your water system.
7. Air in the Water Lines
Air in the water lines can cause the pump to cycle on and off as it tries to expel the air. Check for air leaks in the pipes and bleed the air by opening faucets at the highest points in your home.
Troubleshooting Tips
1. Check for Leaks
Inspect all faucets, fixtures, and toilets for leaks. Use a flashlight or listen for dripping sounds.
2. Test the Pressure Switch
Disconnect the power to the pump and press the reset button on the pressure switch. If the pump starts running, the pressure switch may be faulty.
3. Drain the Pressure Tank
Turn off the power to the pump and open the drain valve at the bottom of the pressure tank. Drain about a gallon of water and then close the valve.
4. Clean or Replace Filters
Locate the filters in your water system and clean or replace them as needed. Refer to the manufacturer’s instructions for specific cleaning or replacement procedures.
5. Bleed Air from the Lines
Open faucets at the highest points in your home, such as the bathroom sink or showerhead, and let the water run until the air is expelled.
When to Call a Plumber
If you’ve checked for leaks, tested the pressure switch, drained the pressure tank, cleaned the filters, and bled the air from the lines, but your water pump still keeps going on, it’s time to call a licensed plumber. They can diagnose the issue and perform repairs or replacements as necessary.
Takeaways: Restoring Water Pump Functionality
By understanding the potential causes of excessive water pump activation and following these troubleshooting tips, you can often resolve the issue yourself. However, if the problem persists or you encounter any complex issues, don’t hesitate to seek professional help from a qualified plumber. Remember, a properly functioning water pump ensures a reliable water supply throughout your home.
