our fresh water tank has a capacity of 55 gal. now you can only fill 30 gal.

Some time ago I opened the drain valve at the bottom of the tank to empty the tank.

I suspect that not enough air could flow in and as a result the tank contracted a bit .

**I'm looking for a solution to restore the original tank size.**

I'm considering filling it with hot water, but I'm not sure if something worse can happen with it ???

Anyone have a suggestion

Thanks in advance.
