Sewer line disconnected.

Over the winter somebody must have spent time under my house, relaxing on my sewer pipe. I discovered it has fallen, and is disconnected. How pleasant. I tried to put the pipes back together, but the pipe no longer fits the flange. Some kind of build up, old glue? Something less pleasant?

There is no 'play' in the lines. My thoughts are to cut off 10 inches of pipe, use a replacement section and a joint connector to fix this. Then use several lengths of strapping tape to support the line in several places. At least one on each side of the tee.

The plan


Is this a good plan?

How would you cut the pipe? Hack saw?

Oh! The glue! What kind? I already have this for a different pipe issue. (From Ace hardware store)

Yes, that is the correct primer and glue.  Make sure there is enough, and the glue has not solidified.
A hacksaw will work; a side grinder with a skinny wheel would be faster.
Wear gloves, and if you have one, use a face shield.
If your original pipe has no play, you may find it hard to make all the connections.
When priming and gluing PVC pipe, you need square cuts and complete insertion of each piece to get a water-tite bond.
If you have trouble, they do sell a slip-on repair piece called a compression fitting, no glue needed.

And a big yes on adding the plumber's tape to support it.

If there is a lack of play in the lines to properly attach the tee with glue, you could look for a Fernco sanitary tee. It is essentially a flexible product that uses hose clamps to hold it on to connecting pipes.
