How to clog/obstruct a pipe

You read well I'd like to obstruct a water pipe (please see the photo)
The problem is that there is a leak somewhere between the floors or maybe on the second floor, in the wall. Pipes are PVC, 18mm diameter. I use a water pump from Mitsubishi EP-205q3

Two reasons I want to do this:
1. it is hard to find a good skilled plumber where I live
2. I don't really need the tap where the leaking pipe leads to.

Due to the position of the pipe, my first choice would be to drill a hole in the pipe, just above the T, and to inject some kind of cement/adhesive to block the water from going up. Question is: what can I use? Something that can be sprayed inside, like a polyurethane spray... just an example. What do you suggest?

Second choice would be to lose one day and try to cut the pipe and then glue a cap. That I should be able to do but it will be more difficult.

Any other suggestions are welcome
Thank you.

Welcome to the forums........

IMO from being a US based plumber is to fit a cap period....................


I know of no injectibles that will work as you describe............

I might even go a step further. Instead of capping the line I would install a 1/4 turn ball valve. This would allow you to turn off the leaking line but give you the option of turning it back on if it's ever needed again.

I'm not a plumber, just pretend to be one at home.
But, if I'm looking at this right, pipe comes into a "T" from the right. Out of bottom of "T" then to the left. The left side of the "T" then feeds the line going up through the floor. With the limited space above, why not bypass that "T" by connecting the right pipe over to the left pipe and then cap the two open ends from the "T".

I would not trust anything you put in inject into the pipe to be safe for drinking water. The only option to do this would be to freeze the pipe, but that is meant for short periods of time to make repairs.
