Causes Of Pool Pump Losing Pressure

Pool pumps losing pressure while vacuuming can be frustrating for pool owners. There are several reasons why this could happen. Blocked suction lines can cause a decrease in pressure, preventing water from circulating properly. Another reason could be air leaks in the suction line, causing a decrease in pressure and air entering the system.

Checking skimmer and pump baskets for debris buildup is also important. Dirty or clogged baskets can reduce the water flow and cause the pump to lose suction. Lastly, any damage to the pump impeller or motor can result in decreased pressure and cause your pool pump to lose power.

Regular maintenance and cleaning can help prevent these issues and keep your pool pump running smoothly.

Troubleshooting And Solutions

If you’re finding that your pool pump is losing pressure when you’re vacuuming, there are a few potential issues that could be causing this. One potential issue could be blockages in the suction line. To locate and identify these blockages, turn off your pump and remove the strainer basket and skimmer basket.

Next, insert a plumbing snake into the suction line to clear any debris. Another potential issue could be air leaks in the suction line. To identify these, run your hand along the suction pipe while the pump is running to feel for any leaks.

To fix air leaks, use joint sealant or teflon tape to seal the leak. Additionally, it’s important to regularly clean the skimmer and pump basket to prevent blockages. If you identify impeller or motor damage, you may need to repair or replace these parts.

And in certain situations, it’s always best to call in a professional for help.

Neglecting maintenance can lead to further issues and expensive repairs down the line. Taking preventative measures will save you time and money in the long run.
