Jet replacement in gunite spa


May 31, 2020

Hello, I am trying to figure out how to replace a broken jet In our in-ground gunite spa. I found the part I think I need to replace here CMP 23315-030-000 1.5 in. MPT Gunite Spa Jet44

I have never replaced a spa jet so not sure if this is all I need to replace or how to go about replacing it. I tried unscrewing the jet from the spa wall but could not and didn’t want to do any damage if I was doing it incorrectly. Attached are a couple pics of the broken jet as well as the empty socket where it was in the spa. Any help on how to go about fixing this would be appreciated. Thank you!

Looks like you found the right jet. It should just unscrew. Get on it with some channel-locks and give it steady pressure. Might help to get it hot, drop the water level, and run cold from the hose into the jet opening to get a little shrinkage on the fitting.
