What is wrong when water spews out of one the three in ground pipes my pool whether filter turned on or not?

Broken Pipe:

- Inspection: Check the entire length of the pipe for cracks, leaks, or damage.

- Repair: If a broken pipe is found, repair or replace the damaged section as soon as possible to prevent further water loss and potential flooding.

Clogged Pipe:

- Inspection: Determine if the pipe is obstructed by debris, such as leaves, twigs, or dirt.

- Cleaning: Use a drain snake or hydro jetting to clear the blockage and allow water to flow properly through the pipe.

Faulty Valve:

- Inspection: Check the valve connected to the pipe to ensure it's fully open and functioning correctly.

- Adjustment: If the valve is stuck or partially closed, adjust it to allow water to flow through the pipe.

Damaged Fitting or Connection:

- Inspection: Examine the joints, fittings, and connections between the pipe and other components, such as the pump or filter.

- Tightening: Ensure all fittings are secure and tightened properly. Replace any damaged or leaking components.

Water Pressure Issue:

- Check Pressure: Verify the water pressure in your pool system is within the recommended range specified by your pool equipment manufacturer.

- Adjustment: If the pressure is too high, adjust the pressure regulator or install a pressure-relief valve to prevent damage to pipes and components.

Faulty Filter or Pump:

- Inspection: Check the condition and functionality of the pool filter and pump. Look for leaks, blockages, or other issues that may affect water flow.

- Maintenance: Clean or repair the filter and pump as needed. Make sure the filter is properly sized and functioning efficiently to handle the water flow.

If none of these solutions resolves the issue, it's recommended to consult with a professional pool service technician for further diagnosis and repair. They will have the expertise to identify and fix the underlying problem, ensuring your pool functions correctly.
