Toilet

If your trusty toilet has developed cracks or leaks, uses far too much water per flush; it may be time to replace it. You consider this a good time to put in a call to the Mill Basin Plumbing and heating plumber; it’s not for the weak, since toilets are heavy and unwieldy.
Stuff a rag into the soil pipe to block sewer gas and prevent hardware from falling in.
Check that the hole in the floor is large enough to accommodate the closet flange up to its collar. If the hole needs to be enlarged, trace around the flange's base with a pencil, then cut away the excess flooring with a jigsaw. Don’t cut any joists.
Dry-fit the soil pipe into the closet bends. Place the flange over the soil pipe, and then measure the gap between the bottom of the flange's collar and the finish floor.
