Question

Installing New Toilet - Was this supposed to happen?


I've never intsalled a toilet before, so I'm looking for some guidance here.

I removed the bolts holding down the toilet and pulled the toilet up…

When the toilet came up, I was surprised to see the blue collar and black pipe were still attached to the bottom (see below).

Aren’t those parts supposed to stay attached to the floor?

Did someone forget to glue that black pipe that is attached to the toilet to the pipe coming out of the ground, or is it supposed to be loose-fit and removable?

If it’s supposed to be attached – is there a special glue for the black pipe, or do I use the same glue I would use on white PVC pipe (purple cleaner and then glue)?

Any other tips to make sure I install the new toilet correctly and it remains secure? The old one was always loose and rocked about (not surprising considering what I'm seeing here)

Thanks!

Somebody cut corners--

Pvc glue will not work---that's not pvc--get the right solvent for that pipe
( That black pipe is not used in my area and the name escapes me at 4:30 am.)

Next--drill through the tile and screw that to the floor--

A hammer drill and a masonry bit will make quick work of that.

They never glued it when installed or the flang would still be on the abs.

They never bolted the flange down to the floor either. You should do that when putting it back down.

edit: Looks like Oh'mike already covered that.

Make sure to line up the flange so the bolts will be in the correct position before glueing or screwing it down.
If it's a slab floor use flat head Tap Con screws, if it's a wooden subfloor use brass wood screws with screws big enough that the heads do not pull through the flange, but do not stick up above the flange.
Always predrill the holes to the size of the minor diam. of the screw threads.
Just hold the drill bit up to the screw to check the size. The outer threads should stick out past the drill bit.

Question

Installing New Toilet - Was this supposed to happen?


Thanks for the replies to my post!.

I've been viewing a few youtube videos on toilet installation, and sure enough it does look like the original installer took some shorcuts. (This is yet another reason I've nick-named the builder of my home 'Gary Shortcut' )

It looks like things got a little more complicated too. As several of you mentioned, the closet flange should be bolted to the ground. It seems that the installer chipped away so much concrete around the drain pipe, that there is no longer anything to bolt it to! Also, the drain pipe starts about 1.5" below the grade of the floor (see photo #3). I bought a new closet flange, and when I put it in place the top is actually nearly flush with the top of the floor (see photo #4).

How should I go about making this right? Should I fill around the pipe with quickrete so there is something for the bolts to anchor to, and the closet flange will sit on top of the new concrete? If I do this, there will only be about 1/2" of the closet flange attached inside the drain pipe since the ground level is much higher than the top of the drain.

By the way - I now realize I bought the wrong closet flange - Should have bought a black ABS flange. Not PVC... This one just looked 'beefier' than the ABS flanges they carried.... Back to the hardware store...

Thanks everyone for your advice and guidance on this. I'm a complete N00b to plumbing.

Yep--wrong plastic---you will need to pack that with a concrete patch of some type---

Don't get the pipe dirty--I'd prime it--then make a card board collar --

pack void with concrete---pull the card board and quickly glue up the drain

Make sure your toilet bolt holes are in the right place

Drill and set the anchor screws after the cement patch is hard

Often times old concrete will not stick to old concrete so it's not likly any screws will hold.
A repair ring like this should get you out far enough to get to get to some soild material.
There's several others that are even bigger and are made to still be covered by the toilet.
Any real plumbing supply will have them if Lowes of Hd do not have them. Even my local hardware store carrys them.

Thanks again to everyone that replied.

I ended up putting a foamboard collar around the pipe and using some Quikrete quick setting cement to bring up the level so the flange would have a level base to rest on, and something to attach to. I first treated the old concrete with quikrete concrete bonding adhesive to help ensure a good bond. I let the concrete dry for about 3 days before drilling holes into the new concrete to secure the closet flange.

I drilled the holes slightly angled outward (away from the pipe) so they wouldn't be close the the inner wall of the concrete and so the holes would penetrate through the new concrete and into the old concrete. Then I used 2-3/4 inch tapcon screws to attach the flange, so they would secure into the old-concrete.

The flange I used glued into the inner-diameter of the 4" drain pipe - (sioux chief 884-ATM). I used this type of flange because it had a longer neck and could reach the drain pipe that was cut a bit short below.

Probably a little over-engineered now, but I think it will be secure and last a long time. Thanks for all the suggestions and feedback.

Looks good and secure. You should be able to tap dance on that commode.

Just remember to knockout the test cap on the flange before you set the toilet
