Hello all,
My new sump has a 1 1/2" bulkhead for the drain into my sump. The problem i am running into is that i have 2 1" drain lines and i think it will decrees the flow of the drains and build back pressure in the lines by having both 1" lines drain into the 1.5". I would maybe like to increase the size of the hole to accomidate a 2" bulkhead. How can i make an existing hole bigger? I'm guessing using a hole saw and clamping a piece of wood underneath it, but what do i place in the whole so the center drill bits grabs it? Any advice would be appreciated. Maybe i'm being paranoid and the 2 lines draining into the 1.5" drain hole would be fine
thanks
Harry
