To fill PVC hot water bag, follow these steps:

Ensure that the PVC hot water bag is clean and in good condition without any visible damage or leaks.

Prepare warm water. You can use tap water and heat it to the desired temperature. It's important not to use boiling water as it can damage the PVC bag.

Open the stopper or cap of the hot water bag. Most PVC hot water bags have a screw or snap-on cap that you can unscrew or remove to access the opening.

Carefully pour the warm water into the bag. Be cautious not to overfill it. Leave some space at the top to allow for expansion and to avoid any potential leakage.

Once the bag is filled with the desired amount of water, securely close the cap or stopper to ensure it is tightly sealed. Make sure it is properly fastened to prevent any water from leaking out.

Before using the hot water bag, check for any leaks by gently pressing on the bag. If there are no signs of water seeping out, it should be safe to use.

Always test the temperature of the hot water bag before applying it to your body. You can do this by placing the bag on a sensitive part of your skin, such as your inner wrist, to ensure it is not too hot and won't cause burns.

When you are finished using the hot water bag, empty the water completely and allow it to dry before storing it. Hang it upside down or use a towel to absorb any remaining moisture.

Remember to follow the manufacturer's instructions and guidelines specific to your PVC hot water bag, as different brands may have slight variations in usage and care instructions.
