I am trying to use 2 inch pipe for everything.. I bought the 1.5 to 2 inch jandy valves and they are perfect with 2 inch pipe.. BUT
I ordered these unions with 2 inch connections and they are the same size as 2 inch pipe..
I thought they would be the same as the jandy valves and connect to 2 inch pipe.. Do I need some kind of slip to connect them? I was trying to avoid doing this... I have 8 of these unions ( 1 skimmer, 3 returns, 2 for the pump and 2 coming off the filter.... The 2 for the pump and 2 for the filter are differant types of unions...
