Well I have the pool build from heck. My 3 year pool is on its 2 nd replaster. Issue with spa jet is holding up replaster and PB will not get someone out. In Texas with record heat and second summer of not having my pool to use. After 1 st replaster one jet quit working in spa. The chip out crew did not remove heads and cracked the head on the spa jet. Head was replaced but now jet does not work when spa turned on. If I turn on the blower air will blow out of jet but with blower turned off it does nothing as other jets spin. I can see plaster in the threads and they have tried to clean that up a few times and just force screw in jet. I assume there is some blockage. Is there any way for me to look at this myself? Pool is empty and chipped out. Plaster company waiting for PB to look at jet. Mind you they have known for a year jet not working and chip out has been for two weeks. I just want a pool to use at this point. Any ideas? Or do I just hire a pool repair company to troubleshoot and fix?
