How To Cap A Residential Sewer Pipe?

Before we dive deep into the discussion, I would request you to be ready with the below-mentioned tools in order to prevent any last-hour misadventure.

Does it make sense?

Tape Measure

Handsaw
Workman’s Knife
Marker Pen

PVC Primer
PVC End Cap
PVC Cement

I hope quite a few of my readers would be aware of the fact that residential sewer pipes are mostly made of either Acrylonitrile Butadiene Styrene (ABS) or PVC hard plastic.

The good thing is that both types are robust, durable, and long-lasting.

Moreover, these residential sewer pipes are available in diameters ranging from 1 ½- to 4-inches.

For joining the pipe sections together, you would be needing couplings, primer, and cement.

MARK MY WORDS, capping a sewer pipe requires installing an end cap that gives a feeling of a straight coupling with one end sealed.

If you’re interested in adding a new pipe to the existing one then all you need to do is to sawn-off the cap.

So, without any further ado, let’s discuss each step in detail.

Step 1

First and foremost, you need to mark the existing PVC pipe at the point where the end cap needs to be installed using Marker pen
The next thing that you need to do is to cut through the mark on the pipe with a handsaw

Make sure to make a straight perpendicular cut through the pipe
Use workman’s knife to scrap away all the plastic scraps
Now, you need to cut into the section and simultaneously remove the unwanted sections of sewer pipe

Step 2

The outside end of the existing sewer pipe needs to be brushed with PVC primer
At the same time, you also need to prime the inside of a PVC end cap

Step 3

Now, you need to brush PVC cement on the primed end of the pipe

Also, brush PVC cement on the primed inside of the end cap
Once you’re done with the aforementioned steps, you need to quickly push the end cap fully onto the end of the pipe
Last but not least, hold the end cap in place for at least 10 seconds, the more the better, and allows the cement to dry fully

Tips For Beginners

Make sure that you’ve applied cement to either pipe end or the end cap only when you’re ready to install the cap in place
The reason why I’m saying this is because the cement takes only seconds to dry
You can also use a circular saw to cut through the existing sewer pipe if handsaw isn’t accessible

Make sure that you’re using ABS cement to seal the pipe cap in case you’re working with ABS sewer pipe
Don’t forget to wear eye protection when sawing through the pipe
