Hi my name is ***** ***** I have been in the plumbing field for 20 years. I will be glad to help you today. It is normal that there is water in the drain. There is a trap on each plumbing fixture that stays full of water. This is to prevent the sewer smell from coming back into your home. You will see similar traps under your sinks in the cabinet. The toilet has one built into it and the bowl it the top of the trap water there.
I haven't heard from you. Was the information I provided helpful?
