Article: Your pumps may be malfunctioning if you can't find a problem with your jets. No water coming out of the jets is one sign of problematic pumps. Other signs are if water is leaking out of the pump shaft or if the water isn't hot. It will cost about $200 to $500 USD to fix pumps. It is best to call in a professional to fix your pumps. Some spas have tabs that hold the jets into place. If you find a jet floating in the water, check to see if any of the tabs have popped off. You may just need to screw the jet in tighter if you don't see a broken tab. If the tab is broken, it is best to replace the jet. You can try to glue it back with a strong adhesive, like super glue, if necessary, though. A leak may come from a crack in the jet housing. If this is the case, you can add silicone to the outer edge of the housing to fix the leak. The leak may stem from the jet gasket or glue joint, which is located behind the jet, if there isn't a crack in the jet housing. Call in a professional if you can't fix the broken pumps. Clogging can prevent your jets from functioning properly. Remove your jets once or twice a year. Soak them overnight in a solution of white vinegar and water. Then, dry them off and re-install them. You can also purchase a commercial cleaner for the jets.

What is a summary?
Check the pumps if the jets aren't working properly. Look for a broken tab if a jet pops off. Check the jet housing to detect a leak. Clean your jets once or twice a year to prevent clogging.
