We are upgrading our pool with a Hayward Matrix 1.5HP Dual Speed pump and I ordered some Custom Molded 21063-154-000 1.5" MIP x 1.5" PVC Hi-Temp Unions for the pump connections. While these unions fit the outlet of the pump nicely, they don't hand tighten into the inlet far enough for the rubber gasket to make a seal. Has anyone run into this issue? I've tried switching the unions around and it doesn't make any difference... I will also be putting some teflon tape around the threads so it will likely be water tight without the gaskets help but I can't figure out why the two female ports on the pump aren't accepting the union threads the same.
