I got a Jacuzzi HydroPur filter and my drain cap is cracked. I hated that thing because I could never get it to not leak and had to call in professional every year. I am thinking about replacing it with a pipe and a ball valve. Anyone thinks it's a bad idea? Should I add an end cap on the end? Is using PVC a bad idea?

Welcome to TFP! 
Might help if you could post a pic or two of the drain cap and spout it goes to so we can see what remains. I'm sure that will drive the replies you receive.

Is that Teflon tape around the threads? That was going to be one of my first recommendation, about 5-7 good wraps though to try and really give that cap something to grab on to.
The cap is cracked. I was thinking about attaching a 45° elbow and a ball valve with maybe a end cap, so that at the end of the year instead of trying to get that cap off, I can just open the ball valve and empty it out.
My concern is expansion/shrinking with summer vs winter (Canada here) of the pipe and pressure.
So my question - has anyone done this before? Should I be ok with a pvc pipe? Should I tread it on or glue the whole thing together?

If you can find a threaded adapter to interface with PVC, I see no reason why that wouldn't work.
I figured out the problem. When you are removing the drain cap, some granules of sand get inside the cap but in between the rubber insert(like a round rubber spacer) that is in the top of the cap. You need to remove that rubber insert with a knife (or something thin), rinse out the cap and the rubber, then reinsert it into the top of the cap and screw the cap back on and voila no more leaks. No Teflon tape or silicon needed. Get a new cap (that is not cracked) first of course.
