Reasons Why Your Pool Losing Water When Pump Is Off

Pool Losing Water When Pump Is Off – RMD Pool Service

 

Have you noticed that your pool is losing water when pump is off? It is a common issue many pool owners face, and it’s crucial to identify the cause before it leads to more severe problems. In this article, we’ll break down the most likely reasons for water loss in your pool and offer simple, practical ways to prevent it. 

 

Common Causes of Pool Losing Water When Pump Is Off 

When your pump is off, your pool may experience water loss for several reasons. The most common causes include: 

1. Evaporation:  

While evaporation is a natural process, especially in hot climates, it shouldn’t account for large amounts of water disappearing overnight. If you notice significant water loss, it may not just be evaporation. 

2. Leaks in the Pool’s Structure:  

Cracks or damage to the pool shell can lead to slow leaks that lead to your pool losing water when pump is off. Look closely at the walls and floor for signs of cracking. 

3. Plumbing Leaks:  

Your pool’s plumbing could also be the culprit. A pool leak when the pump is off could be related to the return lines or fittings. We advise taking on a thorough inspection of the plumbing system for any visible damage. 

4. Suction Side Leak:  

A suction side leak is another common cause of losing water. This type of leak often happens when the pump is running, but sometimes, leaks remain active when the pump is off. 

5. Skimmer Issues:  

If you notice your pool losing water below the skimmer, this could indicate a skimmer crack or a poorly sealed skimmer that allows water to leak out when the pump is off. 

 

How to Prevent Your Pool From Losing Water 

Once you’ve identified why your pool is losing water when the pump is off, here are some solutions to prevent further water loss: 

 

1. Regular Pool Inspections:  

Performing routine inspections can help catch minor problems before they turn into major leaks. Check the pool structure, skimmer, and plumbing parts for any signs of wear and tear. 

2. Fixing Cracks:  

If you find cracks in the pool walls or floor, it’s important to repair them right away. Small cracks can easily turn into large leaking problems over time, causing significant water loss. 

3. Check the Plumbing System:  

Make sure to inspect the entire plumbing system, including the valves, return lines, and pump connections. A small leak in the plumbing can lead to a substantial loss of water. 

4. Proper Skimmer Maintenance:  

Since a damaged or improperly installed skimmer can cause pool leaks with pump off, be sure to check for cracks or breaks around the skimmer area. Replacing a faulty skimmer seal can prevent further water loss. 

5. Use a Pool Cover:  

Covering your pool when it’s not in use can help reduce evaporation, especially during the hot months. While this won’t prevent leaks, it can help manage the natural water loss that comes from evaporation. 

 

What If Your Pool Loses Water When the Pump Is On? 

Sometimes, pools lose water when the pump is running. If you’re encountering a pool losing water when pump is on or pool losing water when the filter is on, it could point to a leaking issue in the plumbing or filter system. Leaks in these areas may only occur when the water pressure is high, so it’s important to inspect all the parts of your system when the pump is active.
