I just watched your YouTube video on how to replace the sand in a Pentair Triton II TR-60 sand filter. Also, the video on replacing the laterals.
Question:
If the sand wears down during the 5-7 year period, do the filtering slots in the laterals wear down as well? If yes, how often should all the laterals be replaced due to wear?
Also, what gradation size number of sand media (i.e. 20, 30, 40, etc.) can 'pass right through' these filtering slots right back into the pool? There is 'zero' specification information available at Pentair.com or at Google for these laterals.
Quickrete makes a Pool Filter Sand (Model 115350) available in 50 lb. bags rated at #20/#40 gradation available at the Home Depot for $9.98/bag.
Quickrete also makes (3) other types of sand mainly for concrete construction - coarse, medium and fine, in 50 and 100 lb. bags. Also sold at the Home Depot.
Coarse #1963 - #12 to #30
Medium #1962 - #20 to #50
Fine #1961 - #30 to #70
Can either the coarse or medium sands be used as well for my Pentair sand filter? Or a combination of both?
Thanks for your time!
