septic junction box

i dug up my junction box because my tank lid was lifting up allowing septic onto ground. my question is should the junction box hold water or should it all go to fingers and junction box be basically dry

I'm a city boy so I went to google for a graphic that makes sense to me.
I hope it may make sense for you too.

If the tank lid is lifting then it very likly your field is plugged or failed,
There's always going to be some water in the box but if it's working properly it should not be full.

Mine always has about 3 - 4" of water in it unless a surge of outflow is coming in. But I also have adjusters for the laterals so that I can tweak the amount of flow or even shut one off for a period to kind of balance the drainfield useage.

By junction box do you mean septic tank or distribution box? Septic tank always full unless just pumped out. Dist. box should flow out until bottom of leach lines are exposed

There are typically two or more outgoing lines from the distribution box. The liquid level in the distribution box should be equal to the level of the lowest of the bottom of the outgoing lines. If the liquid level in the distribution box is higher than the lowest outgoing line, it indicates that the lowest outgoing line is not installed correctly, the field is clogged, or the pipe in the lowest outgoing line is damaged.
