Hoping someone can suggest replacement eyeballs for my spa or provide some insights on what I'm working with. The ones that came with the spa are push-in/slip-in and all the same size, some had electrical tape wrapped around to keep them secured in the pipe. I"m guessing someone installed the wrong size at some point and did this to keep them in. Three of the return pipes seem to have an indentation 1" inside the pipe, the other two pipes have an indentation about 2" inside the pipe. I thought it was odd that these are different lengths. Does it suggest I need two different length eyeballs?. Amy suggestions or input would be appreciated.
