I use in some of my enclosures fairly large water bowl (8" round) it might be a thought to use a extra large water bowl.
When I buy bowls I buy at least two per snake so they can be swapped easily and cleaned when you have time.
Personally I give fresh water every couple of days at that time wipe out the bowl with a clean sponge. Every second fresh water I replace the used bowl with a clean one and fully wash (soap and water) and disinfect (f10sc) the bowl. If it has been fouled I use F10scxd to wash the bowl and disinfect with F10sc. Once a year I wash every bowl with F919 as well.
