Pro Service Tip: Use a Vacuum lock
Do you have a suction side floor cleaner in your pool? You know…those Kreepy Krawlys or a Hayward Navigator, PoolCleaner, Zodiac Barracuda or MX8 etc? If you do and it is plugged into a dedicated suction line in the wall, not directly into the skimmer, then you will ALWAYS want to make sure you are using a vacuum lock.
A vacuum lock is a threaded spring loaded clamp that both holds the floor cleaner hose in place so that it doesn’t accidentally fall out, and it also closes in case it is pulled out, to prevent swimmers from getting sucked on to or their hair sucked into an open and active suction line.
This is a very simple and effective safety device that can prevent injury. If you have a floor cleaner plugged into a dedicated suction line in the wall, check and make sure it has a vacuum lock.
