58 Year Old Closet Flange

Post by blaubner » Sat Aug 31, 2019 1:01 pm

I bought a house built in 1961. The home is built on a concrete slab. I live in the south east.

One of the bathrooms clearly had water damage when I bought the home. I’ve noticed now that a substantial amount of water was coming out from the bottom of the toilet when flushed.

I removed the toilet to expose the old cast iron closet flange. It was loose, chipped and corroded. It clearly needed to be replaced. I removed the flange easily with a pry bar. I’m now finding a layer of sand as the sub flooring.

Is anyone familiar with this? Again, the house is on a slab. If I stick my 5-1 into the sand I find the slab about 2 inches in.

How am I going to attach a new closet flange? Any idea why I’m finding sand?

Is this room a couple inches higher than the other rooms? It seems as if they used a sand base under the tile maybe to level the floor. With all the moisture it has softened up. This would generally have been used to shape a shower floor to provide slope to the drain but I have never seen it used on an entire room?
So what is the pipe made of ? it looks like there is a flange still on it? If there is they must have just had extension rings stacked on it? Maybe one of the other guys has seen this before? lets see what they say.

I've never seen a mud base over a slab either, which perplexes me. I think you're also correct that the original flange is still and I suspect that a raised flange was set into the tile/mud bed.

How to fix this now kind of depends on what you're doing to repair the floor. If you are going to fill the hole in and reset the surface tile, then get a flange extension and set it, mud around it to for support of it and the tile, set the tile. Done!

If you're stripping out all that old flooring, what does this do for the level of the floor in relation to the rest of the house?

The floor of this room is at the same level as the rest of the home. I believe the pipe is cast iron. I removed something that was cast iron as well. It looked something like the attached image, only 58 years old and cracked into two pieces. I'm going to replace the floor in this room and will bump the thread back up once the problem is resolved.

What is the floor throughout the house? As was said earlier, it's odd that there is a mud bed over a slab.
