So now you know that when water is heated up it expands. This is also where it starts to expand beyond what is expected. This reaction causes extra pressure creating a little bit of a mismatch.

The expansion tank will give your water that second chance it deserves
There even could be other problems you need to give attention to as well. Such as water leaks in faucets, leaks in toilets, and also problems in your flush system to name a few. So if you have a closed system in your home, then definitely an expansion tank has to be initiated to your plumbing system.
This isn’t a complicated fix either. Having an expansion tank will give this water line’s pressure relief valve’s annoying leakage a simple fix. The expansion tank will help by giving the water a chance to flow back to safety when expansion starts.

This rule also applies to hot water heating systems; when a boiler heats the water in a hydronic heating system, the expansion tank allows for the water to expand without the pressure relief valve leaking. If the pressure relief valve on a boiler system chronically leaks, even after replacement, it probably means there is a problem with the expansion tank.
