I have a 3" drain on my driveway next to the house which takes rainwater and
puts it back into the city's sewer system. During stormy weather the drain
has a tendency to slow down or stop because of bits of twigs, leaves and
other debris start to accumulate around it. If this happens it's possible
that my garage floor gets flooded because a small lake starts to form around
the drain. I've heard of laundry sink strainers can help. Do they make this
in a 3" size? How else could I fix this problem?
