Why is the Pool Pump Leaking?

If you notice water pooling around your pool pump or a significant decrease in water pressure, there might be a leak in the pool pump. Several reasons could be responsible for the leak, and diagnosing the issue is crucial to fix it. Here are some potential reasons why your pool pump might be leaking.

1. Cracked Housing

The most common cause of a pool pump leak is a cracked or broken housing. The housing is the exterior framework that covers the motor and impeller of the pump. Over time, the plastic housing can become brittle due to exposure to weather conditions and the chemicals used to keep the pool water clean. When the housing cracks, water can seep in and out of the pump. You can visually inspect the housing to see if there is any apparent damage. If the housing has a crack, the best option is to replace the whole pump.

2. Leaking Seals

The seals of the pool pump might not have a physical crack, but they may be worn out or dirty. When the seals don't function efficiently, water can pour out of the pump. Removing the pump and replacing the seal is a moderately easy task, but it does require some mechanical skill. If you're unfamiliar with fixing pool pumps, you can hire a professional to do the job.

3. Broken Valves

Pool pumps are connected to a multi-port valve that directs water to different filters and backwash systems. If the valve breaks or wears out, it can cause water to leak from the pool pump. Inefficient valves can also cause water to backflow into the pump, putting extra pressure on the housing, leading to cracks. Replacing a valve is a relatively easy procedure, but it involves shutting off the pump and draining the pool water.

4. Loose Fittings

Sometimes, water leaks might come from a loose fitting. Water can gush out from the gaps between the fittings and pump. Fixing this this problem is usually a simple fix, and it doesn't require extra materials. Tightening the fasteners in the relevant locations can prevent the leak. However, you should use a wrench and be careful not to overtighten them.

5. Clogged Strainer Basket

The strainer basket is a component that collects debris before sending water to the pump. If the basket becomes clogged, it can restrict the flow of water to the pump, causing it to overheat and crack. In case the basket sticks, it can force water to leak out of the housing at the lid's base. To fix the issue, you should remove the basket, clean it, and reinstall it.

Taking Care of Your Pool Pump

To reduce the likelihood of a pool pump leak, proper maintenance is the key. You should keep your pool pump clean and well-maintained, especially during the off-season when it's not in use. Also, you should regularly inspect the pump and take note of any unusual sounds, heat patches or water leaks. In case you're concerned about water leakage or require assistance in maintaining your pool pump, you can contact a pool maintenance professional to help you.

Final Thoughts

A swimming pool is an excellent asset for your property, but maintaining it can sometimes be a tedious task. If you spot water around your pool pump, don't ignore the issue. Instead, investigate the problem and diagnose the problem before it leads to significant damages. With a little knowledge and the right tools, you can quickly fix most pool pump leaks.
