When I switch my pump into high speed, it looks like there is dirt shooting through the returns for about 5 seconds. I only use high speed for priming the pump after cleaning the strainer basket, and sometimes for vacuuming. The filter does a great job keeping the water sparkling clear, even with the considerable amount of debris I get in the pool. I'm not sure when the sand was last changed, if it ever has. Is there anything I should try before removing all the sand and inspecting the internals?

You should try resettling the sand bed, the same thing you do when the filter is channeled. See this post for instructions.
I'll give it a shot this weekend.I just heard today that I will have the next 4 days off from work 
so, I went out to the pumphouse and opened up the filter to clean as suggested. I stuffed the garden hose in the sand bed and cranked it up, and WOW 
there was a TON of nasty stuff in the filter! I kept the hose going for about 2 hours, moving around every 10 minutes or so, until the overflowing water was clear whenever I moved the hose. Did a decent job of flooding the pumphouse and the yard behind it. Looking at the nasty crud that seemed to never stop coming out of my filter, I find it hard to belive the previous owners EVER properly backwashed the filter, let alone clean it like I just did :grrrr: After doing this, it probably would have been easier/less mess, to just change the sand, but I probably spent a buck or two on water as opposed to about $50 on new sand. Plus, sitting out there cleaning the filter was a good excuse for a few
