PVC T cap

[soremekun]

I am using a 4x4x4 PVC Tee. It is laying flat and looks like an upside down T with one end point straight up in the air.
The pipe that is going into the Tee is just temporary and I will be cutting off in a few months. The pipe entering the Tee is too short to cut off and then cap.
I was wondering if there was a cap I can put over this end of the Tee since I cannot put a cap over the pipe.
Basically, I want to cap off this opening of the Tee. Is there a cap I can buy?

First off you shouldn't be installing a sanitary tee on it's back. It should be a Y and 45. As far as capping it will the cap be permanent or temporary?

Thanks for that info.
The cap will be permanent and will be burried.

you could use a line cleanout plug and glue the cap on... you should not be installing it on its back as john has stated.

A 3" DWV fitting will usually glue inside of a 4" pipe. Then a short piece of 3" pipe with a 3" pressure cap on the end of that.

And as has been mentioned, a sanitary tee should not be laid down.

Thanks for the info, all.
Why shouldn't a sanitary tee be laid flat? Could it burst from pressure?
Will it be an issue after it is capped off?

If this is a pressurized line, you should not use drainage fittings at all, as they are not designed to handle pressure.

If this is a drainage line, a sanitary tee is not designed to force the drainage water to flow downstream when it is installed flat. In it's intended position, gravity does most of the work directing the water downstream, but in a flat position, a combination wye and 1/8th bend is necessary to send the water downstream.
