Sealing sump pump pit - other option besides caulk?

Hi, a couple years ago we had a radon system installed. Along with that, a submersible sump pump was installed, and the cover was sealed with silicone caulk. Recently the sump pump failed and I installed the same one, but have not yet sealed the pit. I believe the old one may have failed because it ran too often (it may have been set too low).

Is there a more not-so-permanent method of sealing the pit?

Basically I want to monitor the water level and may possibly adjust the setting of the sump pump, but don't want to have to deal with removing caulk every time.

Any ideas?

Sealing the cover depends on how your radon system is set up. Does the radon system have a line that goes thru the sump cover ?

If the sump pit cover is just the pump only I would think you could use a high density foam around the inside of the cover where it meets the floor. The use of foam in that application may require longer cover screws.
