Can't find toilet drain in basement
Builder has exposed drain pipe for shower and wash-out drain against wall for vanity, yet no exposed toilet ring in cement floor. It is all stubbed down for water and air vents, but nothing visible for the toilet. We have drilled holes in the cement where we think the toilet will go with no luck. There is a bathroom directly above the basement bathroom area. Would it be in the same area below it? Since it has been 5 years, the builder can't recall the property but insists the plumbing is there. Help!
