I just recently remodeled my 1983 vintage pool with spillover spa. Everything is nice and new ...except for the spa jets. I am trying to replace them now but I can't tell what to buy for replacement. I realize I can go find an adjustable spanner wrench to get this off but honestly I am a bit worried I will tear it up getting it off and then find that it is non-standard and I can't get a replacement. That concern is spawned from the Baker Skimmer models that my pool has. Any ideas or help is appreciated.
