New house - attached spa jet problem/question

[PoolioAndTheGang]

Hey all. .I did some research on this but I'm still confused. I just moved into a new house that has an older (1980's) inground pool with attached spa. The spa has both the regular sized pool return jets as well as 4 large "hot tub jets". The pool-size jets work just fine. I can fill or drain the hottub, it heats up, etc .. but nothing comes out of the jets. If I put my hand over them, all 4 feel *very* slightly like they are sucking water.

Do you think they're not hooked up to anything? I checked around for what might be an air pipe and I found several candidates. Not sure . .would it be located near the pumps . .or near the spa? If near the pumps then I think I found it and it's filled with water . .looks like rain water.

Basically . .I have no idea, lol. It seemed like the other pool/spas I saw in my researching had only the large spa jets . .or else they didn't show/make mention of the regular-sized jets.

Thanks for any thoughts/ideas!

Any pictures of the spa and equipment could really help

Can you turn your valves to spa only what happens?

Here are pics. The first one is filter side and includes my primary air pipe suspect. The second is return side w heater.

If if I turn the valves to spa only the small jets run and the water level in spa stays constant but nothing from the large jets.

Sorry. That's the second pic - return side. Here's the filter side w pipe.

ha . .ok . .hopefully it's obvious . .the return side w/heater is on top, the filter side with the water-filled pipe is on the bottom...sorry about that and thanks for the help!

When you say small and large returns in the spa could you also take pictures of them.

Here is one of each - hopefully you can see them. The little ones are just regular pool jets. They get the water whipping pretty good just by themselves.

Figured it out . .well, not by myself but I talked to the guy who had cleaned the pool for the last 5 years before we bought the house. The filter is old, the sand hasn't been changed in at least 5 years, the pump is undersized - he thinks this model should have a blower but it doesn't.

Anyway -not a huge deal. .we were not likely to have used it .. just wanted to see if it worked. We're getting the pool resurfaced at some point in the near-ish future and we'll deal with the outdated equipment then. Thanks!
