repairing toilet flange


hi,

about 4 yrs ago, when we rented our house (we own it now), the landlord had a plumber fix a toilet, it was rocking. well its doing it again. i removed the toilet today, withour even removing the two mounting bolts! it has what looks to be a pvc flange and pipe. the slots in the flange are not broken, but pulled up from the rest of the flange. the only thing i can tell, is the bolts must of worked their way from the slots to the holes in the flange and popped out. would a good fix for this be to get one of those rings that fit over the old flange and screw into the floor/subfloor around the outside of the flange? also, i beleive that the subfloor is concrete. so should i mark and drill holes in the concrete, and insert anchors? or just drill and use small lag bots to secure the ring to the floor....bob

Secure the bolts to the slots on the flange using extra nut and washer on each side, that will secure the bolts, now set the toilet. Thats how I do all my flange bolts, this way bolts wont slip out of the slots.

If you go that route make sure you use a brass or stainless steel hardware otherwise it will seize making removal difficult and/or it will rot away completely. Are the slots in the flange deformed in any way?

ron, marlin,

the slots dont seem to be deformed, just pulled up, like a small hump, i guess from being tightened too much. they are not broken. i will try to bolt the closet bolts to the flange, then set the toilet, and mount the toilet with nuts and washers from the top...bob

If you can, run corrosion resistance screw into the sub floor near the slots on the flange, this will help in keeping the slots of the flange tight to the floor.

You are correct. A raised area along the slots indicated over tightening or someone yanking on the bowl. Gently tap the area back down with a hammer and it should be fine.
As for anchoring into the slab use the plastic sleeves. You drill a hole, insert the sleeve then put the screw into that. I like the lead sleeves better but I don't think you can buy them anymore.

Forget it was a slab floor, so Marlin have you going in the right direction.

repairing toilet flange


hi guys,

lots of great ideas, thanks! just thought of this. after i tap down the slotted holes. put a star washer under the head of the closet bolt. this way when i set the toilet, and tighten down the closet bolts, the star washer, should i hope grab into the pvc flange and not slide.

Should work, secure the bolts to the flange 1st, then set the toilet.

Is the flange all PVC? Or does it have a metal ring around it? If it's all PVC forget my comment about hitting it with a hammer.

You can dry fit the bowl first to see where they go if you are more comfortable that way. Typically the bolts go as far out to the sides are you can get them. The holes in the bowl are much larger than the bolt so you have some play with it.

Yes you can dry fit 1st, then adjust bolts if needed before you set with the wax.
