If you think you’re having a problem with your spa — and you think it might be the pump — remember you don’t necessarily have to replace the entire spa to get back in business. With a little help, you can probably diagnose and repair the problem yourself, picking out the spa parts you need. Here are a few tips:
- If it looks like the pump is leaking water, check to see if one of the nearby plumbing connections is the real culprit. While a pump *can* leak as a result of a damaged seal plate or other more catastrophic internal failures, the more likely source of water is going to be one of the nearby joints – or the unionright at the connection to the pump. If it’s the seal plate, we have those too.
- If it sounds like the pump is rattling or grinding, it’s most likely the pump not getting enough water, causing the bearings to go bad prematurely. That’s nearly always caused by a leaking shaft seal. While you can replace the shaft seal and bearings, it’s easier to simply replace the pump motor itself. Check to make certain the motor you’re installing has the same specs as the original (see our list of things to write down here).
- If the pump doesn’t stay on, or turns on and off intermittently, the most common cause is poor electrical connections. This could be something as tricky to chase down as a wire pulled out of place — or as head-smackingly obvious as plugging a 230-volt spa pump into a 115-volt outlet. They’ve also been known to overheat and shut down if the ventilation around them is poor — find a way to get a little more air, and see if the problem persists.
