Thank you so much for this . . . spa installer had spoken about having to remove all the pump unions to release air . . . no mention of the dedicated release valve on the front which you demonstrated . . . .lifesaver, thank you. !!
Thank you! I was looking for a Hot Tub repair person when I found this video. I think you just saved me a lot of money on something so easy, any homeowner can do. Thank you, thank you!
Yes air locks will prevent the water from reaching the heater depending on which pump is air locked. If you have a dual-speed pump or circ pump model and those are airlocked, this will cause no flow to the heater. Also this is something that needs to be fixed right away or turn the power off until you can solve this. You don't want any pump to run dry or you can cause damage to pump and seals. On the south seas models you need to make sure water level is to the top of the cap. If it gets low, it will suck in air also causing the tub not to heat.
Yes you can also use a car oil filter wrench to loosen the union. This method will also work, however it's easier with the bleeder cap. You can use some pliers and gently unscrew it.
