Maintaining a pool is never easy—at least, when it comes to the tedium and actually keeping on top of it. At times, you might even have your tools fail you while you’re trying to work on the upkeep. Keeping things working smoothly can be difficult, especially if you noticed that your pool pump loses pressure after a few minutes of work. What causes this to happen, anyway?
A decrease in pressure in a pool pump is caused by air in the pump. You should check your pool pump’s suction line for leaks or clogs. Sometimes, having a dirty filter can also decrease the pressure you have. Performing a backwash can help you avoid this issue.
Having a pool pump that suddenly loses pressure can be annoying, but it’s not an emergency. Even so, you should make an effort to fix the problem sooner rather than later. Otherwise, your pool will likely suffer for it.

What Could Make A Pool Pump Lose Pressure After A Few Minutes?
Pool pumps can lose pressure for a wide range of reasons, so it’s actually fairly difficult to figure it out right off the bat. In order to determine what’s causing your pump to die after a couple of minutes of use, you’re going to have to do a little detective work. To make troubleshooting easier, we’re parsing out instructions on a step by step basis.
Start By Doing Basis Equipment Maintenence
- Clean out your pool filters. Make sure that all your pool’s filters, including the ones used in the pump, have been cleaned. If you need to, try to perform a backwash to see what can be done.
- Look at your draining hoses for clogs or impediments. Sometimes, pool pumps can lose their ability to keep a certain pressure level as a result of clogs in their lines. If you notice that your pool’s line is folded, unfold it. If you notice a clog, use a reverse flow line to plumb it out or use a clog eliminator like Drain King.
- Open up the pool pump’s motor. If you know how to do this, then opening up the pool’s pump motor is a good idea. Remove any debris and hair that is stuck in the equipment, close it up, and replace the pump’s motor in its rightful place.
With many pool systems, the maintenance alone will be enough to curb most issues. If you aren’t sure whether you need to go to the next portion of your troubleshooting, do a quick run of your pump and check the PSI reading.
Check Out The Suction Lines
- Start by looking at the lid of your pool pump. If your lid isn’t perfectly stuck on tight, then the airflow could be compromised from there. Close the lid at your pump if it’s open.
- Then take a look for leaks in and around the suction lines. Airflow in your pump line is one of the most common reasons why you might lose pressure after a few minutes. You might need to call a professional pool maintenance crew if your lines are covered by concrete. If there are any leaks found, patch them up or replace the piping that broke.
- Check for cracks along the edges of the lines’ rubber seals. Another place to look for leakage is around the rubber seals that keep your pipes locked in place. Fixing any holes that you have around the seals can easily improve your airflow.
For the most part, doing this will solve the vast majority of problems that deal with your pool pump. To make sure that your pump is working, give it a run and wait to see if it shuts off by itself. If it continues to shut off, you still might be able to pinpoint the cause and fix it.
Could It Be A Bad Pool Pump?
For the most part, you should expect to see your pool pump problems fade away after you completed the troubleshooting above. If you can’t find an air leak and everything is well-maintained, there is a chance that you might have a pool pump that is going bad. However, you usually will see several symptoms kick alongside a sudden loss of pump pressure.
Most pool pumps that are on their last legs will have specific issues that signal it’s done. For example, pool pumps gone bad tend to make strange noises, might have low flow rates, and may also have a motor that turns off mid-run. Should you notice these things, it’s time to consider getting a new pump.
How Much Does It Cost To Replace A Pool Pump?
The price you pay for a new pump will depend on whether you decide to DIY it or hire a pro. A DIY pool pump replacement typically costs between $150 to $800 depending on the pump motor you’re replacing. Hiring a professional to do the work means that you will pay between $700 to $1,500 for the work to be done.
If you have an unusually high-end pool, you might find yourself paying extra to get the pump replaced. The high end of pool pump replacement prices caps out at $2,400. However, you shouldn’t expect to pay this much unless you have a custom pool and a very unique pump system.
How Long Do Pool Pumps Last?
Another sign that your pool pump could be going bad is its age. If your pump stops having pressure after short periods of running and has been getting up in years, it makes sense to replace it. Most pool pumps will work perfectly fine for up to eight years. From eight to 10 years, most pool owners will see a decline in their pump’s quality or need a replacement.
There are incidents where pool pumps last for as long as 20 years. However, this is the exception to the rule rather than the rule itself. You should expect to replace a pool pump every decade or so.
How long should I run my pool pump every day?
When your pool is in service, a pool pump should be run at least eight hours every day. This will help circulate the water in your pool, clean out stuff that shouldn’t be there, and keep your water fresh. If you so choose, you can run the pump for longer. Going over the minimum is more of a preference than a rule.
Can you run a pool pump 24 hours a day?
Though you only need to have your pump running eight hours every day, the ideal runtime would be constant. This is because having the water constantly flowing prevents plant growth and also helps keep the pool running at optimal efficiency. So yes, you can run a pool pump for 24 hours in a row. It’s actually the best thing you can do for your pool!
Why does my pool get cloudy after I vacuum it?
If you’re noticing that your pool is starting to gain a milky appearance after a vacuuming session, you probably need to shock your pool. The most common cause of cloudy water is a lack of chlorine. Another potential reason for a cloudy pool is the need to improve your pool’s clarity through clarifiers and a quick vacuuming. If all else fails, consider doing a thorough cleaning to make things clear up.
What does it mean when a pool pump loses its prime?
A pool pump that loses its prime means that your pump has air inside of the head, preventing it from being able to move liquid around. Since this affects your ability to get pressure out of your pool pump’s functioning, many people use “losing its prime” and “losing its pressure” interchangeably.
What happens if my pool pump runs dry for a long period of time?
You should avoid letting your pool pump run dry whenever possible, simply because it poses a risk to the pump’s integrity. It can blow out your shaft’s seal, cause leaks to occur, and in extreme cases, cause the pump basket to melt. If you’re very unlucky, the shape of your pool pump might become deformed as a result of the dry run.
