    "Rinse" position on multivalve

    Do I understand rinse correctly as: The same water path as "filter" position, but sends water to waste line instead of back to pool?

    Yes. Flushes the pool side of the sand after backwashing.

    You got it.

    I use it when backwashing ... switch between backwash and rinse until the backwash is clean. I have heard bout using it when charging with new DE also so that any DE that makes it past the grid does not end up in the pool (although I have never seen this to be a problem).

    I agree it should not be a problem. However, in my limited experience, as well as my limited expertise, and possibly my limited intelligence, I always seem to get a little bit of DE back into the pool when recharging. Just enough to be annoying...

    Next time I backwash/recharge I will follow a slightly different procedure. Instead of recharging in filter position, I will leave the multivalve in rinse while I recharge with DE. I don't think it will waste too much additional water because this part of the overall procedure happens fairly quickly.

    I may pay attention a little more and see if any is sneaking past for me as well ... I agree it really should not be very much water loss at all to leave on Rinse.
