55 gallon tank plumbing problem

[edc_aquarium]

It’s not really an emergency but I was just wondering what I can do for my plumbing to see if everything works since I’m only 15 my parents won’t let me put water in the tank to test it out

Without putting water in the tank, it's pretty much impossible to test if it will hold water...

So I guess I would suggest talking with your parents about what their concerns are, and then take steps to resolve them. For example; if they are concerned about the water leaking all over the floor, perhaps take the tank outside to test it (assuming it's small enough to move, of course).
