How to Spot and Fix Pool Plumbing Issues Before They Get Worse
Owning a pool is great—until something goes wrong with the plumbing. One day, the water is crystal clear, the jets are strong, and everything is running smoothly. The next? Low pressure, strange air bubbles, or worse—water loss you can’t explain.
Pool plumbing problems don’t fix themselves, and waiting too long can turn a minor issue into a major (and expensive) repair. If you live in Lincoln, Rocklin, Roseville, Granite Bay, or Sheridan, knowing what to look for can save you time, money, and frustration. Here’s how to spot and fix common pool plumbing problems before they become disasters.
Common Signs of Pool Plumbing Issues
Not all pool plumbing problems are obvious, which is why it’s important to stay alert to even the smallest changes in your pool’s performance. If your water pressure drops, air bubbles appear in the jets, or you notice damp spots around your pool deck, you might have a hidden issue brewing.
Ignoring plumbing problems can lead to wasted water, rising utility bills, and unnecessary strain on your pool’s filtration system. Over time, small leaks can cause damage to surrounding structures, leading to more costly repairs. The sooner you spot an issue, the easier it is to fix without draining your wallet.
Low Water Pressure in Jets
When your pool jets stop pushing out a steady stream of water, it’s a sign that something is restricting the flow. Weak water pressure can be caused by a clogged filter, an air leak in the plumbing, or a failing pump.
Before you panic, start with the easiest fix—check and clean your pool filter. A dirty or clogged filter can slow down water circulation, making it seem like there’s a bigger issue at play. If cleaning the filter doesn’t restore water pressure, check for air leaks in your pump or skimmer lines.
Air Bubbles in the Return Jets
Seeing bubbles coming from your return jets might seem harmless, but it’s actually a sign that your system is pulling in air instead of just water. This usually happens due to a suction leak somewhere in the plumbing.
The most common culprits include a loose pump lid, cracked O-rings, or air leaks in the skimmer line. If left unchecked, too much air in the system can put strain on your pump, reducing efficiency and shortening its lifespan. Catching and fixing suction leaks early can prevent costly repairs later.
Sudden Drop in Water Level
Some water loss is normal due to evaporation, but if you find yourself refilling your pool more frequently than usual, you might have a plumbing leak. A sudden drop in water level can indicate cracks in underground pipes, loose fittings, or damage to the skimmer line.
If the leak is underground, it’s not just a water problem—it can lead to shifting soil, causing cracks in your deck or foundation. Ignoring a leak for too long can result in major structural damage, so it’s important to identify the source and fix it as soon as possible.
Strange Noises from the Pump
A pool pump should run smoothly without making loud or unusual noises. If your pump starts gurgling, grinding, or whining, there’s likely a problem with the impeller, motor, or plumbing connections.
Gurgling noises often mean air is being pulled into the system, while grinding sounds suggest something is stuck inside the impeller. Whining noises could indicate the motor is wearing out. Addressing these issues early can help extend the life of your pump and prevent expensive replacements.
Water Puddles or Damp Spots Near the Pool
If you notice wet spots around your pool deck, equipment pad, or backyard, there’s a good chance a slow plumbing leak is to blame. These leaks might not be immediately noticeable, but over time, they can lead to erosion, mold growth, and even damage to surrounding landscaping.
Underground leaks can be particularly tricky to locate, so if you suspect one, it’s best to call a professional. Catching leaks early prevents further property damage and keeps your pool running efficiently.
How to Troubleshoot Pool Plumbing Problems
Before calling in a professional, there are several troubleshooting steps you can take to diagnose and fix minor plumbing problems. By following these steps, you may be able to resolve small issues before they turn into costly repairs.
Check and Clean the Pool Filter
One of the simplest ways to improve water circulation and restore pressure is to clean your pool filter. Over time, debris, dirt, and algae can clog the filter, restricting water flow and putting stress on your pump.
If you have a sand or DE filter, backwashing can help remove built-up debris. For cartridge filters, rinsing the cartridges with a hose or soaking them in a filter cleaner solution can improve performance. Keeping your filter clean ensures proper water circulation and reduces the risk of plumbing issues.
Inspect the Pump Lid and O-Ring
A loose or damaged pump lid is a common source of air leaks in a pool system. If the O-ring under the lid is cracked, dry, or worn out, it can allow air to enter, causing bubbles in the return jets.
To fix this, remove the pump lid, inspect the O-ring, and replace it if necessary. Applying a silicone-based lubricant can help create a better seal and prevent future air leaks.
Perform the Bucket Test for Leaks
If you suspect a leak, the bucket test is a simple way to determine whether water loss is due to evaporation or an actual plumbing issue.
Fill a bucket with pool water and place it on the pool steps so the water level inside matches the pool’s water level.
Wait 24 hours without running the pump.
If the pool’s water level drops more than the water inside the bucket, there’s likely a leak that needs to be addressed.
Check for Clogged Pipes
Clogs in the plumbing lines can restrict water flow, leading to weak jets and pump strain. Common causes of clogs include leaves, debris, and calcium buildup.
Using a plumber’s snake or a high-pressure hose can help dislodge minor clogs. If the blockage is severe, a pool professional may need to perform hydrojetting to clear out the pipes.
When to Call a Pool Professional
Some plumbing problems require expert intervention, especially if DIY fixes don’t solve the issue. If you’re experiencing continuous water loss, underground leaks, or pump failures, it’s time to call a professional.
Specialized tools like pressure testing and leak detection equipment can pinpoint the exact location of hidden plumbing issues. Addressing problems early prevents further damage and ensures your pool remains in top shape.
Preventing Future Pool Plumbing Problems
Regular maintenance is the best way to prevent plumbing problems from escalating into major repairs. Scheduling annual pool inspections, maintaining proper water levels, and keeping pipes clean can help extend the life of your pool system.
Keeping an eye on your equipment and addressing minor issues early can save you thousands in repairs. A little proactive maintenance goes a long way in keeping your pool plumbing working efficiently year-round.
