Pool Pump Loses Pressure After a Few Minutes
Spending time in the pool is the perfect way to spend hot summer afternoons. Who doesn’t like a good pool time anyway!
Sometimes you might not enjoy your pool time due to issues, one being lost pressure. People complain about the pool pump not running at full capacity or the pump suddenly losing pressure (just so you know, you are not alone).
There’s not much to worry about if your pool ditched you. There might be a problem with the gauge, or the pool might be needing a cleaning, or if worse, there might be a leak.
Here’s everything you need to know if your pool pump loses pressure after a few minutes.
Why does my pool pump keep losing pressure?
Fixing the pool pump is not much complex once you get your hands on the underlying problem. To find answers to why does a pool pump loses pressure, check the following issues in your pump.
The most common issue in pools that leads to the malfunctioning of the pool pump is the accumulation of debris in different parts of the system. You will need to check the motor, filter, and hose to make sure no debris is present. In case of clogging due to dirt, you can easily clean it yourself without professional help.
Air Entrapment in Suction Line
Air or leakage in the suction line is another common reason if the pool pump loses pressure after a few minutes. Air is usually trapped in the system due to low water levels in the pool. Check for the strainer basket if it is closed tightly. If there is space for air to enter the suction line, it can affect the airflow and be one of the causes why the pool pump loses prime after a few minutes.
Cracks and Leaks
You might need professional help to fix your pool pump; when the pool pump starts strong then gets weak. Inspect the thread sealant, o-ring, impeller housing, and rubber seals to ensure no leaks are cracks found in the pool. You may also run the pump to observe if any leaks are present.
Apart from the suction lid and clogged lines, do not miss to check the valves. Sometimes when the pool pump primes then lose pressure, it is caused as a result of a leaking foot valve. While these valves are present in the pool pump to keep water in the intake line, a faulty valve may cause problems in the pump. Replace the valve to get your pool working smoothly.
The Pool Pump Starts Strong Then Gets Weak. Why?
If you wonder why does my pool pump loses its prime after starting, you might need to check for a suction leak that causes low pressure. Check all parts of the pump, including the drain plugs and o-ring, to eliminate the possibility of air entering through any cracks. If the leak is large, it will suck more air into the system, causing damage.
How to Increase The Pool Pressure?
It is possible that your pool pump suddenly loses pressure despite having a fully functional gauge or none of the above-mentioned issues. In such a situation where your pool returns low pressure, follow these instructions to increase pool pressure by yourself.
- As a low pool pump loses pressure after a few hours can be caused by low water levels, filling the pool at the proper level.
- Check the suction pump and replaces hoses if any unrepairable leaks are found.
- Clean the skimmer basket after a couple of weeks to avoid the buildup of debris that results in clogging.
Why does my pool pressure fluctuate?
While you might experience that your pool pump loses pressure after an hour or so, sometimes it may show a fluctuation in the pressure. An air leak majorly causes this fluctuation through a crack. When air enters the pump, it has a higher tendency to get sucked, eventually obstructing the normal functioning of the pool pressure system.
How to fix the cracks and leaks?
Depending on the size of the leak, you may fix the leak yourself by sealing the cracks or leaks. If the damage is beyond repair or the line is concrete-covered, do not hesitate to ask for professional help. The cracks can be sealed with duct tapes if the rubber seals are not in place properly.
What to do when the pump runs dry?
Never run your pool pump dry! Yes, immediately switch off the pool pump and only operate when the pool is filled with water. Running it dry will damage it, and it may need a permanent replacement.
How long does a pool pump last?
Pool pumps last for as long as 12 years, while the motor or the plastic on modern ones might need replacement.
If your pool pump loses pressure after a few minutes, check all parts of the pump, including the motor, hose, filter, and rubber seals, to make sure no leaks are present. Use duct tape to seal the leaks or seek professional help if the damage is beyond repair. Additionally, never run your pool pump dry and ensure adequate water levels in the pool for the smooth running of the pump.
