Dom,

It may be different in this application but when I used to run the pool business we only changed the sand every ten years. They actually worked the best after about two years. Althought you are running 24/7 and pools are usually 8/7. Basically you check the pressure guage when backwashing doesn't bring it back to the working pressure its time to change the sand. Hope this helps.
If you were closer I would help with the plumbing good excuse...

Let me know if you need anything I have a bunch of JG fittings and tubing.

Thanks Walter What exactly is the proper working pressure for my model filter? It didn't cross my mind to double check that. I just followed the recommended water flow rate.

Dom,

Updating the thread, but just like I said about 15 psi above normal pressure, maybe less for that pump? But that is when I would backwash.
Talk to you tomorrow.
