Ok according to the brs site a 3/4 inch uniseal requires a 1 1/4 in hole. I've already drilled a 1.5 in hole. Would my hole be too big?So why not replace with 3/4" uniseal? when I say 3/4" i mean designed for 3/4" pvc I don't know the actual sizes off hand but they make them for pretty much all standard pvc sizes.
