Customer called us out to replace both upstairs toilets. On inspection both toilets had leaks from the bolts connecting the tank to the bowl. I pulled both toilets. Both toilets had broken flanges and the hallway toilet had a leaking shut off valve. I replaced the toilets with new supply line, wax ring, closet bolts and china caps. I did not tighten toilet all the way down to prevent further issues with the flanges. Customers were advised not to use toilets till tomorrow.
