I'm putting a bathroom in our basement and have been moving right along
up to this point. How do I attach the toilet flange?
Do I have to glue the flange to the drain pipe? If so, do I still need
to secure it to the concrete floor? If so, can glue be used or should/
need I use cement screws? I'm trying to avoid drilling into this (very
hard) poured concrete.
Thanks,

Rent or borrow a hammer drill and set some plastic anchors in the
concrete. With a hammer drill it will only take a minute or so to drill
both holes. If the flange is not secure you will get a leak for sure.
What are plastic anchors? And why not metal ones?
Thanks.
This is how I installed a cast iron floor flange and I believe that this
is the standard method. The floor flange has a collar that fits around
the cast iron floor bend with a gap. Molten lead is poured into this gap
and tamped into place with a special tool. Be sure the hold down bolts for
the toilet are in place in the floor bend and be sure to use a level to
make sure the floor flange is level before the molten lead cools.
>Do I have to glue the flange to the drain pipe?
>>Yes, you have to glue the flange's tailpiece to the drainpipe.
> If so, do I still need to secure it to the concrete floor?
>>Yes, the flange also has to secured to the concrete floor with a mechanical bond (not glue).

>>No glue, as above. Check at your local home center for some sort threaded, galvanized
