I am replacing the sand in my hayward 244t sand filter. I noticed when I removed the lateral assembly that there was sand in the
- the laterals
- the joint between the laterals and the central pipe
- the hollow portion in the center where all the laterals are connected
After disassembly I noticed that the ball and socket of the laterals have striations from the sand, is this normal?
While the laterals look fine to me , I am at a loss as to how the sand got into the assembly. I also wonder if the striations are creating a gap
wide enough for the sand to pass through. Do you think that the entire assembly need to be changed?
