I am looking at adding a couple of unions to the return line for ease of access, and these would be in the back of the tank. A leak would be a minor disaster.
Just wondering if people have experience on leaking or non-leaking of return lines which are under pressure.

I have unions on my return PVC piping to be able to take my check valve out for cleaning and it's never been a problem, just don't over tighten them. Do up hand tight then 1/8- 1/4 turn more with channel lock pliers.
