Fittings are parts that connect pipes and tubes that are made from a variety of materials. When it is time to replace or remove a fitting from a pipe, it can be a challenging task but with the proper tools and knowledge, it can be done easily. Here is a detailed guide on how to remove a fitting from plastic pipes.

Materials required:

– Adjustable pliers
– Screwdriver
– PVC pipe cutter
– Hacksaw
– Heat gun

Steps:

1. Turn off the water supply – Before you start removing the fitting, you should turn off the water supply to avoid any accidental leaks. If the valve is leaking or not working properly, you must shut off the water supply at the main valve.

2. Drain the water – After turning off the water supply, the next step is to drain the excess water in the pipe. You can do this by opening a faucet or valve at the bottom of the system to allow the water out.

3. Loosen the joint – Use adjustable pliers to loosen the joint threaded on the plastic pipe. First, turn the fitting counterclockwise to remove it from the pipe. Once you have loosened the joint, you can pull the fitting away from the pipe.

4. Remove the push-fit fitting – If your plastic pipe is connected a push-fit fitting, the process is a little different. Push-fit fittings usually have a clip or collar that you must remove. With a screwdriver, move the collar and then gently wiggle the fitting to remove it.

5. Cut the plastic pipe – If the fitting is stubborn and won’t budge, you may need to cut the pipe to remove the fitting. You can use a PVC pipe cutter or hacksaw to cut the plastic pipe as close to the fitting as possible.

6. Heat the fitting – If the fitting is still not coming off, you may need to apply heat to loosen it. Use a heat gun to heat the joints and fittings around them. Make sure you wear gloves and goggles while doing this step as it can get quite hot.

7. Use pliers – Once the fitting has been heated, use adjustable pliers to turn it counterclockwise gently. You should be able to remove the fitting without much force.

8. Sand the pipe – After you have removed the fitting, use sandpaper to clean the end of the pipe to ensure a smooth surface.

9. Install a new fitting – If you are replacing the old fitting, you can install a new one by following the manufacturer’s instructions. Install the new fitting to fit tightly on the pipe, ensuring that it is properly aligned to prevent any leaks.

In conclusion, removing fittings from plastic pipes is a task that can be done easily using the right tools and following the above steps. Always ensure you have turned off the water supply before the removal process. If you’re unsure or uncomfortable with the process, it’s best to consult a professional plumber. Additionally, always put your safety first by wearing gloves and goggles while working with a heat gun and similar tools. By removing the fitting properly, you can prevent any damage to your piping system and avoid potential leakage issues.
