How to push fit a pipe connector
Installing a push-in plumbing fitting is effortless and can be done in minutes. However, there are things you should not overlook when fitting, cutting and installing the pipe. For example, you need to be very careful when cutting the pipe for joints avoid damaging the «O» ring in the fitting. Here is a step-by-step guide to installing the push-in pipe connector.
1. Decide on the pipe material to use
Push-fit connectors are compatible with almost all types of pipe, such as PEX, PVC, copper and CPVC. So, the first step in installing the fitting is the choice the pipe material that properly matches your fitting size and needs.
2. Cut the pipe
This is a vital step in the push-fit installation. The pipe should be cut as straight and round as possible to ensure it fits into the push fitting to avoid leaks. Cut the required length with a pipe cutting tool suitable for the type of pipe. For example, use a plastic cutter if you are using plastic pipe.
When measuring the length to be cut, remember that about 1 inch of the pipe goes into the push connector to make an accurate measurement of the depth of the fitting.
Pro Tip: Don’t use a hacksaw to cut the pipe as it will result in mismatched edges.
3. Deburr the pipe by removing any sharp edges or burrs
After cutting the pipe, smooth it by removing any sharp edges or burrs that may damage the push-fit «O» or cause a leak. Next, use a deburring tool to remove sharp edges and burrs left by the cutting tool. A deburring tool effectively reams the pipe inside and out, removing all sharp edges.
Alternatively, you can use the boring tool behind the cutter for reaming the pipe and an emery cloth or fine sandpaper to sand the outer edges.
You do not need to deburr if you are connecting plastic tubing such as PVC or CPVC piping. However, you can ream CPVC pipe with a ridge on its inside edge with sandpaper or emery cloth. Then wipe the pipe inside and out with a clean cloth.
Pro tip: Some deburring tools come with a gauge that marks the depth of the fitting.
4. Mark the pipe
Measure and take a marker and burr depth gauge to mark the depth of the fitting on the pipe. Insert the tool into the end of the pipe until it stops, then mark the pipe at the edge of the tool where it stops.
However, you can use a tape measure instead of the burr depth gauge if you don’t have one. Measure the pipe from its end to the length specified by the manufacturer that is suitable for the fitting.
5. Install the fitting
Some types of push-fit fittings, especially those for plastic tubing, have an insert that must be pushed into the pipe before being installed. With however, copper fittings do not require an insert and are installed directly into the fitting.
If your pusher has an insert, push the insert firmly into the pipe first. Then press the pipe into the fitting or the fitting into the pipe until it can’t go any further. The point where it stops should be the exact spot of the mark; this indicates that the pipe is correctly fitted in the push fit.
Next, rotate the fitting or pipe 360 degrees clockwise or counterclockwise to install it and establish the full tightness of the connection. Most fittings have a twist-lock mechanism and cannot be removed once locked in place. You can try pulling the pipe to confirm how strong it is; if it does not move, the fitting has been successfully installed.
How to remove push fittings
There are different types of push-fit fittings, and the method used to remove them depends on what kind of fitting is being installed.
1. Turn off the water supply
Before removing a push-fit connector, you must turn off the water to avoid any damage in the removal process. It is best to turn off the water supply at the water meter, which is located near the sewer pipe or on the side of the house.
2. Identify the push fitting type
You may not perform this task properly if you do not know the type of fitting you want to remove. Push fasteners come in various types and shapes; some are common brass fittings, copper fittings, speedfit and John Guest.
3. Remove the fitting
Use a suitable release tool, a horseshoe clamp, to remove the pipe when desired. The tool goes over the fitting and helps remove the pipe. Attach the tool to the release collar of the fitting and pull the pipe from the other end.
