From the department of one thing leads to another...
I noticed the fill valve in a seldom used basement bathroom toilet wasn't shutting completely, so I ran and picked up a Fluidmaster to replace it with.
The replacement was a no brainer, but while leaning on the toilet to reach the shutoff I noticed the toilet shifted slightly.
I soon discovered that the pressed steel toilet flange was badly rusted, and the flange bolts had pulled through it, That steel flange was held down only by the flange on the end of the PVC drain fitting.
A few minutes work with a hammer, chisel and pliers removed all the remains of the pressed steel flange. Now I just have the PVC drain, surrounded by concrete. (With a piece of foam rubber and a few bricks keeping the sewer gas where it belongs for the time being.)
My thought is to use my hammer drill to sink two holes a couple of inches deep in the concrete at the appropriate locations. (Looks like i'll have at least 1-1/4" inches of concrete betwen the holes and the outside of the PVC.) Then I'd drop in a couple of 5/16" brass or stainless bolts and fill the holes with Rockite, the stuff used to set machine anchor bolts into concrete floors.
That should let me put on a wax ring and lower the toilet down over those bolts. Seems to me they should hold the toilet down as well or better than that pressed steel toilet flange did.
Anyone else do it this way? Or, is there a reliable repair flange made for this kind of thing that won't require my having to drill into the concrete anyway to anchor it down?
Thanks guys,
Jeff
