So I want to update something that happened out of the blue last night .
My son used the spa with his friends and they were sitting there for few hours , the water level was down under the tipe , maybe 3"-4" under the tile (exposed the plaster) , so I stepped outside to check on them and this is the first time that happened , I see 2 of the jets working , pushing water and air , the blower was off , I have a 3 watly valve installed on the blower pipe (at the equipment pad) so I can control the amount of air coming out at the spa .
Today was the first time i see water and air actually coming through the spa wall unless i use the blower , I was very excited and that what I was looking for , spa action without blower , so now I have to figure out why the other 4 jets doesn't work .
I ordered 1/4" anyway so I can get better velocity.
Do you think the amount of air was only enough for 2 jets because it was too far (120' from the spa) ?
I flush the pipes before installing the new jets today .
By the way I did exactly what you told me , I cover both ends with epoxy and drilled holes but I think some fly out with the water pressure , and if the epoxy was holding the water were shooting not in straight line it was changing from thin to thick or the opposite on some of the jets .
Maybe that's because I drilled uneven holes on the epoxy (on both sides).
I will respond tomorrow with the information about the pump gpm and psi and we will go from there but dt least I see something moving in the water tonight makes me happy ..
Now , after I changed to pool mode to refill the spa the jets stopped then I tried again in spa mode but this time the jets didn't have air and I cannot see any water like I did before , maybe anything to do with the water level ?
The water level was not even close to the jet opening , it was maybe 8" to 10" higher
If you look on the bottom left jet , you'll see it want to start but no success .
