Anyone play the trumpet here?

i have problems w/ my trumpet, the valves are loose. i dont kno wut to do,.

when i like move the key around, it's like loose..

loose as in they sink fast, i usaully like them like that but i know my friends like them sterdy so they apply some valve greese on them. its the thick one. i think its called bach slide greese but i know theres many more.

You need to elaborate more on the problem, it could be any number of things, but you must be more specific...
