In this guide, we are going to show you how to remove “push-fit” pipe connections.
These kind of fittings connect pipes together by “clawing onto” them and creating a watertight seal.
As a result, you will not be able unscrew “push-fit” fittings. In other words, if you attempt to loosen these connections with a wrench, they will continue to rotate until your hands begin to tire.
Trust me. I’ve been there.
The fact that you cannot unscrew these can be confusing to DIY plumbers.
In the photograph above, you can see an old brass push-fit fitting that connects two copper pipes together. You can also see by the marks that someone has attempted to loosen this fitting by using a wrench.
However, this will not work as there is a “claw” inside the connection that will not let the pipe go.
It is worth noting that these fittings can also come in the shape of “elbows” or “bends”.
How to remove brass push-fit fittings.
To remove these kind of fittings, you will need to push in on the plastic part and then pull the pipe out.
This plastic part can be any color. In the examples above, you can see that the plastic part of the connection is green.
Although it is possible to push in on this plastic by using your hands, doing so can be pretty difficult and sore on your fingers.
The best tool to use is a push-fit “demounting” tool. More often than not, this tool will look like the shape of a horse shoe.
Note that the demounting tool in your local hardware store might not look exactly the same as the one above. For example, some of them will be longer and others will have a notch or a grip at the top.
How to use a push-fit demounting tool.
Unfortunately, the instructions on the back of some of these tools can be poorly-drawn. In fact, you might even discover that there are no instructions at all!
To use the demounting tool, simply push it onto the pipe.
Here, you can see that I have forced the tool onto the copper pipe. Now, in order to loosen the fitting, I will push it towards the plastic part.
If everything goes to plan, then the plastic section on the connector will compress inward and release the copper pipe. At that stage, I will be able to pull the pipe out.
Using an adjustable wrench or a ring spanner.
You can also try to use an adjustable wrench to do this job.
As the name suggests, an adjustable wrench (or spanner) is a wrench that allows you to adjust the size of its “jaw”.
This will allow you to tighten the wrench around the pipe until it fits.
Note that it should only loosely fit the pipe. In other words, you do not need to tighten the wrench so hard that it scrapes along the pipe.
Once the wrench is in place, you can then push it towards the release mechanism on the fitting.
It is worth pointing out that you can also do this with the head of a ring spanner. However, the ring spanner will need to be the correct size.
