I have a 3in building drain running about 6in or so above grade in a tall crawlspace. The floor joists are 3-1/2 feet above the pipe. What's the best way to support the drain?
I was considering using concrete blocks every 4', but I'm wondering if there's a chance the ground may settle. Plumbers tape hanging down 4' seems flimsy. Maybe tack a 2x4 vertically from the joists, with a strap at the end to the pipe..?
