Help, I am trying to replace a 10 yr old pool pump with a new Hayward 1 1/2 HP unit. I need a recommendation on how to remove the union that connects the pump to the DE filter. My issues is that when I turn the union (assuming counter clockwise is correct), and also having another wrench securing the threadeded side connected to the filter, the threaded side connecting to the pump will tighten until it cannot go anymore. If the union piece is only supposed to turn then let me know. otherwise the hacksaw is comming out to seperate the pieces (LOL). Also thinking of using strong flex tubing & clamps to connect once I remove.

Additional Info: If I replace with another union, can I buy this from Home Depot? Is the standard 1 1/2 inch? Can I use PVC?

What you are describing sounds like a coupling and not a union, it also sounds a little like there isn't even a coupling only a piece of pipe between the two. Take both the pump and filter off the stand as an assembly. One of the parts has to be able to turn completely around. This shouldn't be to hard as there are probably some mounting screws holding both the pump and/or the filter to a base. Take both parts off the base, remove the filter, remove the pipe, throw away the pump. connect the pipe to the new pump, connect the filter to the pipe, align the pump and filters to the mounting holes and re-attach the assembly to the mounting bracket. Then connect the power to the pump and check for leaks. Make sure you use some pipe dope of Teflon tape on the threads.
One last note: Make sure you leave about a 1/4 turn in the tight direction on the filter. After you screw down your pump, then turn the filter, in the tight direction, to the proper position. This will ensure your filter is in the proper postion and the joints are tight - no leaks.
Hope this helps

I am not sure how much you know about the construction of a pipe union but it might be a good idea to go down to the local hardware store and look at a couple of unions to see how the three pieces go together and in what direction you need to turn the connecting piece of the union in order to loosen it.

I am assuming the current union is metal. If so, place a hammer on one side of the union nut and then tap (not heavy pounding) on the nut with another hammer or pipe wrench. It sounds like the nut "seized up" on the threads. This may loosen it so you can remove it. You can replace with PVC.

Without actually seeing the union in question, all I can do is guess. Some unions tighten onto both pipes as you turn it. So going in 1 direction tightens both pipe ends, rotating the other direction loosens both pipe ends.
Some unions snap together and shouldn't be reused.

get out the hacksaw. and do not use flex tubing, you'll come home oneday and your yard will be flooded and your pool will be empty.
