So I have an in ground pool and spa with an overflow waterfall. When running the spa, I no longer consistently get bubbles out of the jets. I do not have a blower, just an air pipe. I recall there used to be some suction at the opening of the air pipe, but it is almost undetectable now. Intermittently, I do get some bubbles out of 2 of the jets.
So far, I've tried:
- Checking the air pipe for obstructions, but I have not tried snaking it out. The air pipe opening faces down, so other than maybe spiders, I doubt there's much in the pipe.
- Draining the spa below the level of the jets and filling again. When I do this there are bubbles for a while, but when the water gets high enough, they stop.
- Attaching the output of a wet/dry vacuum to the air pipe. That didn't help although last time I had this problem about a year ago, it did seem to resolve it.
Our spa does not get much use. This is probably the first time I've tried to use it this year. Perhaps lack of use contributes to the problem.
I have no idea what is going wrong or how the air pipe connects to the jets.
Any ideas how to fix this?
If I bought a blower would that fix the problem?
