Spa jet wasn't working - solved

[strategy400]

We had one spa jet not working, in fact it would suck water in. I removed the jet venturi nozzle with a 9/16 socket on a long extension, as described on other posts, it was just barely hand tight and I just snugged it up when I reinstalled it. I found this rock lodged in the nozzle.

400,

Good job..

I am not sure why a clogged nozzle will suck water in, but it is a pretty common issue.

Did you take out all the jets, and then blow out all the junk, or did you just do that one??

Thanks for the pic.

I only did the one as the rest work as expected. I suspect the air inlet had some kind of vacuum effect as the other venturis pulled air into their jets but no air was being drawn into this particular jet. Here's another photo for scale

Possibly I may have introduced this rock into the system when I plumbed my solar. I hope there aren't any more lodged in my gas heater. There's also a SWCG and automated valve in the line...
