What's the cooldown on the levers in Bazir seal (Pits of inferno)?

Question

I regularly check on POI Bosses and when I check on Countess Sorrow (Phantasm Boss) I like to use a lever that takes me directly to the entrance of the seal. Sometimes I can't use it because it hasn't changed back to its original position. Also, when I pull some levers they disappear but eventually reappear, so what's the cooldown on these levers?

Technically speaking, these aren't cooldowns. When you pull those levers the map changes "permanently". But they'll appear again when there's a floor reset in the area. Floor resets usually happens every 6-8 hours, but not at the same time on all places, and are also not related to players' actions (but they won't happen if there's a player in the area). So to answer your question, you would have to pull a lever and then check that spot as often as possible, without staying in that area, until you can narrow it down to a time span and double check it afterwards. It's not very pratical and tbh not really worth it imho.
