Keeping your pool water at an optimal level includes filling the pool when water loss from evaporation occurs. If you find yourself filling a pool more frequently, it’s possible a leak has developed. Water loss in your pool may be the result of pool pump leaks. There are three main areas where your pump can leak:

  • Motor shaft seal
  • The intake or suction line
  • The return line

These are the three areas to look at closely if you see water on the floor of the pump room. The hoses or lines that take in water and force it back to the pool after filtering may be loose. Tighten the threaded connections if needed.

Motor Seal Shaft

A motor seal shaft leak is easy to identify. You will notice dripping from the area of the seal shaft in the pump housing. The seal keeps water from contacting the electrical parts of the pump motor. Replacing the seal can be easily accomplished. It should frequently be checked for leaks to protect a larger electrical issue from developing.

An ignored seal leak will cause water to damage the motor and cause significant problems. The impeller that turns on the shaft controls pressure to the moving water. It can also crack and water can damage the shaft seal and motor. Check the impeller, too.

Intake Leaks

Pool pump leaks caused by the intake lines are often the result of a hose that is not connected tightly to the pump unit. An underground crack or tear can also be responsible. 

Intake symptoms include:

  • Cloudy pool water.
  • Weak suction at the skimmer basket or drain.
  • Visual air bubbles at the strainer.
  • Lower pressure tilter tank.
  • The pump needs refilling.

When the intake hose breaks, the suction line takes in the air instead of water. The first action is to check the connection to the filter and pump. It should be tight to allow the water to be sucked into the filter and continue to the return line.

Check the skimmer basket and the area around it for a crack or tear in the pool wall. The suction line may be plugged and need cleaning where it meets the skimmer.

Excessive water on the decking is an indication of a broken suction line close to the skimmer assembly or under the deck. This line break will affect the pump because it cools the water returning to the motor.

Return Line Pool Pump Leaks

This leak check also begins by observing the return line connected to the pump motor assembly. Water dripping from this line is a clear indication that the connection is the problem. Water will not return to the pool if the return line comes loose. A loose return line will lower the pool's water level.

This PVC line can have a crack that causes a small leak. This repair is also an easy one, but it is still important to replace the part before it becomes a major problem.
