It is not uncommon to find water condensation, often called CPAP rainout in your CPAP hose; however this can be quite uncomfortable and noisy while you are trying to sleep. Signs of condensation could be runny nose or sore throat. Try these options: Try using a heated hose. If your CPAP machine is able to have a heated hose integrated into it, this will alleviate condensation issues almost immediately. Note that not all machines have the ability to have a heated hose, so if you are unsure, check with your provider if this is an option for you.
