How To Troubleshoot A Pool Pump Vacuum


If your pool gets dirty, the pool vacuum should suction the debris, and send it through the filter. Pool pump vacuums work similar to a household vacuum, except it uses a pump system to circulate water through the head. 

Many issues cause the vacuum to malfunction such as leaks or lack of suction. Follow these troubleshooting tips to fix the pool pump vacuum.

Fix Suction Problems

Ensure the vacuum hose is firmly connected to the skimmer basket. The hose commonly attaches to a plate over the skimmer basket, and if the hose won't stay attached, the plate may need replacing. 

The skimmer filter should be free of debris and obstructions, and the pump basket housing isn't cracked. Check the water level to make certain it comes above the skimmers, and add more water until the skimmers submerge. 

If things look properly connected, undamaged, and clean, air could be present in the line. Before you connect the hose, push the hose underwater about six inches at a time, and let it fill with water to purge the air. This can also be done by laying the hose over the water return. 

Check the Pump Strainer Seals

Examine the strainer lid on the pump. If the lid seems loose, detach the lid and inspect the rubber o-ring for damage. Inspect the O-ring on the joint or union that connects the strainer chamber to the suction line by detaching it with a screwdriver.

Cover the joint threads on the strainer chamber with thread tape. Replace damaged O-rings, and lubricate them with a water-based lubricant before installing. Use the screwdriver to work the new seal into the threads, and tighten the joint.

Repair Leaks

Inspect the lid of the strainer pump while the pump runs. If you see bubbles inside the glass chamber, it could indicate a suction leak.

To find hose leaks, fill the hose with water, and slowly remove the hose, keeping the nozzle under water. When you notice water spraying or bubbling, you found the leak. Temporarily seal the damaged areas with duct tape until you finish cleaning the pool.

You may also buy a waterproof hose repair spray for a temporary repair. Mist the leaky area with the spray, and let it stand based on directions. Another way to fix a leaky hose is by cutting the hose at the leak and attach a connector by clamps.

Sometimes, the motor shaft seal inside the pump gets damaged. If you aren't familiar with pool pumps, get it serviced by your local swimming pool repair.

Talking About Pool Seal Replacement

Hi there, I am Carrie Burke. The pool at my old house always seemed to spring a leak in the winter. I had a pool repair professional identify the cause of the constant leaks after living in that home for several years. The contractor let me know that the seals around the pump housing were slowly going bad. Replacing one seal at a time was just prolonging the maintenance process and causing damage to the electrical components inside the housing. I elected to have all of the seals replaced at the same time to prevent future leaks. I will use this site to detail the seal replacement process for you all. I hope that you can use the information I provide to keep your pool in perfect condition. Thank you for visiting my site.
