Shut Off Valve

[musiclvr56]

I am not going to use one of my toilets for one month. Other than water evaporating (don't know if I can pour water into the bowl if and when it gets low), is there anything negative-can I have plumbing problems by not using the toilet for a month? I will explain later why I want to keep it off. Thank you.

There are thousands of toilets in thousands of homes that are not used for over a month. Basement toilets, guest room toilets, workshop toilets, etc. And you can pour water in the bowl if it gets low, but you won't really have that issue in Massachusetts for only one month.
