So we're recovering from our harsh (for Memphis) winter and I wanted to start getting the pool in shape. I needed to replace my pressure gauge on the filter (broke over the winter) as well as the O-ring around the lid to the filter as it was slowly leaking.
I knew you had to release the pressure somehow....so I stupidly...so stupidly...pull the sand drain plug at the bottom of the unit. I thought it was just a water/pressure release plug...didn't realize it was the "sand drain". Needless to say an ***-ton of sand started rushing out of the filter.
So now I'm committed to changing the sand as a good portion of my sand rushed out.
HomeDepot sells Quickrete No. 1153 "Pool Filter Sand" for about $4per 50lb bag. The side the the filter calls for #20 silica sand...and the particle size called for on the side of the filter seems smaller than the quickrete stuff. Am I correct in assuming i need to buy the expensive sand from my pool supply store rather than the cheap stuff from home depot?
Also...any other tips when i start filling the sucker back up with 275lbs of sand?
Thanks for the help....
Oh..I attached a picture of the label from the side of my unit.
