This is my first sand replacement attempt. I emptied and discarded old sand. Pulled out the laterals/tube assembly and carefully checked for any breaks or cracks, then cleaned everything. All was ok. Just completed refilling the filter with 175 lbs. of new sand, VERY carefully scooped in with a 24 oz. grain scoop. All went well and the tube is exactly centered. (sometimes it pays not to hurry, according to my wife!) The pool still has the intake and return valves turned off; the filter has not run at all yet this year. Upon lifting the winter cover, our water is crystal clear. I want to do a 2 minute backwash, then rinse the new sand prior to opening the pool for filtering. Should I add water to the filter sand to settle it prior to backwashing? Or just close it up, set my multi-port to backwash, prime the pump, turn it on, and let the pool water come in? Thanks in advance.
