marinegrunt Posted July 17, 2022 Report Share Posted July 17, 2022 I was given an older hot tub from a buddy of mine who purchased a house that had it and he wanted it gone. It's a 2001 Cal Spa. I currently have the side panels off due to a cracked hose. That's how I noticed a couple 1" hoses that aren't hooked up to anything. There's one on one corner and the other is in the corner diagonal from it. Each hose runs up to a Tee that connects to a plastic lever located on the top rail of the tub. In the manual it says that some models have a jet booster. Is that what that hose is for or does it have it be hooked somewhere in order to have the jets work? I know it'll be easier to troubleshoot once I have the leak fixed and it's up and running but it would be nice to get them hooked where they need to be while I'll have the tub flipped on its side. I guess if water pours out I'll know it has to be connected somewhere. If it doesn't it's for the jet booster that isn't there? I attached a photo but will get a better one tomorrow. Since the tub is on its side this picture was snapped from the bottom looking up. The blue hose runs into another Tee where one port continues with 1" hose around the tub and the other port has five ½" vinyl hoses coming off of it. Thanks!

CanadianSpaTech Posted July 17, 2022 Report Share Posted July 17, 2022 Might be for air injection that adds air into the stream of water to "boost" jet performance. 1 Quote Link to comment Share on other sites More sharing options...

I suggest you call CalSpa, but don't be that optimistic that they can help, it seemed to me in my couple of calls over the years that their "tech help" wasn't so good.... 1 Quote Link to comment Share on other sites More sharing options...

When you say "adds air" do you mean it just sucks air from the environment and it doesn't have an air pump or anything it should be hooked to? I never would've considered that but sounds logical. One thing I didn't think of until now is when I pulled the panel off the opposite corner the hose was dangling on the outside of the paper wrap that surrounds the tub so I could tell that side has never been torn into. That also backs up what you said. Good news for me. One less thing to mess with. Quote Link to comment Share on other sites More sharing options...

Yes when the valve is opened air gets sucked/pulled into the stream of water through venturi effect. You want to keep these valves closed when the spa is not in use. It will pull air from inside the cabinet that is cooler than the spas water temp having a cooling effect. 1 Quote Link to comment Share on other sites More sharing options...

Here I was worried about taking a hot tub that's 21 years old! That makes me feel better. I read somewhere on here that the red and blue hoses that Cal Spas used were prone to cracking. I'm replacing one of those now but I think it was due to a leaky cover over the winter and winter temps. I also had to replace a 12 port manifold. While I have a lot of foam dug out and, the hot tub flipped on its side, do you think it's worth the work to replace all hoses or should they be good to go since the hot tub is now in place? I guess my main reason for even considering it is because the thought of spending money on spray foam and then possibly having to tear it back out looking for another leak down the road. If you have original hoses that are still holding on I'll feel much better about not replacing them. Although, I'm going to replace the cabinet panels so it would be nice to know everything is solid. What do you think? Is it even worth it to replace all hoses on an older spa? Supposedly the 2 main pumps are new within the last 3 years so I have that going. I would call Cal Spa and ask but sounds like they wouldn't be able to help. 🙂 Quote Link to comment Share on other sites More sharing options...
