Hey Hot Tub Owners! Here are two easy tricks to fix your hot tub jets if they’re not working. First, make sure your jets are open all the way. Most jets are adjustable, so turn them all the way to the open position. Secondly, try burping your jets. If you’ve just refilled your hot tub, you probably have an AIR LOCK inside your pipes. You can get the air out of your jets by running the jets on low for 20 seconds and then high for 20 seconds. Do this a few times to get the air out of your system.
