I just installed a second hand hot tub at my house. I went and filled it up and noticed there is water coming out the top of a inner piping assembly. This is essentally a manifold that feeds all the jets. At first I thought it was some type of overflow because I originally put a little too much water in it but it never stopped coming out regardless of the amount of water in it.
If I turn the jets or blower on I noticed that it stops leaking and it sucks air inside of the top of the pipe which leads me to believe this should maybe stay open.
My question: Should I buy a cap to cap this off or is there some type of valve inside that needs to be replaced?
Please see the attached photo.
Thanks so much everyone.
