Are you saying you can't pump to backwash or waste? Either way will pump out the pool through the skimmer, just as chief suggested. I'd be willing to bet your shallow end is 3.5 ft deep. Bottom line, I still don't trust your cya test results. Wait until have your r-0013 refill to make sure you have an accurate result. Using the same sample, do it over and over again until you have the result repeatedly the same.
No, the OP can't backwash or pump to waste... this was already discussed.
