You cerainly CAN turn the pump off between cycles. It won't hurt anything. I have just been able to do it quick enough (turn the handle) so I don't feel I need to.

Yes, the manufacturer instructions say back and forth 3 times. I usually do it 4-6 times during the growing season. Just want to make sure I get all the junk out.

I've given a lot of thought to adding a blower. I guess I'm just too cheap. But when taking the head off to validate the cleanliness of the media, I don't find any clumping and when I stir the media by hand, it doesn't seem to be accumulating more than normal detritus on top or bottom.

The drain cap I spoke of doesn't really have a line from the filter. It goes directly into a small sreen fitting at the bottom wall of the filter body. I would say it's about an inch and a half in total length. Don't know about other filter brands but you're probably right. If there's a line of any kind, I would open it with the pump running to clear it first. Just make sure you re-pressurize the filter before turning the pump off and start your backwashing routine. Also, I was only speaking of the drain cap on an Ultima II filter. I can't speak for how this part of my routine would work on any other brand.
