Thanks for the reply.

I'm not sure exactly what a "half union" is. I wasn't able to remove the tubing from the pump last fall so I don't know if <any> of it comes apart. I just know that it's oozing water now. I'm afraid to turn the pump back on for fear that the pressure will make it blow (a loose clamp did this a couple of years ago and we lost mega gallons. (OK. I'll fess up. I'm a woman and am on a steep learning curve for all this technical pool stuff. It seems that I just get one thing figured out and two more problems crop up. It's getting old.)

I'm also very afraid of <really> screwing something up. Also, since the system is all connected, how would I remove a tube and not rapidly drain all of the water I've just added in my attempts to clean up the algae problem I had.
