need skimmer drilling tips for recirc mod
I am going to do the recirc mod on my ASM G2 skimmer
It looks like most use a holesaw 1 3/4 for the 1" uniseal
What precautions can I take to prevent the skimmer tube body from cracking when I drill.
I would hate to have something happen wrong that puts me out of a skimmer.
