u/Guanine_Cytosine

I’m renting a house and the home owners have had it for three years and when they moved in this Free Flow Spa was on the back patio. They never used it for three years and now I’m renting and was interested in using it.
Everything seems to be working but I have a leak! The leak is from this pipe (in video). I’m not a handy man but was thinking maybe I could try to fix this connection? Otherwise how expensive do you think it would be to hire someone?
Thank you!
