empty it, then add a frame round it. Theyre not meant to be sealed.

It's knackered. Replace it, £125 for a tank from Screwfix, £90ish plus
delivery from BES.
You will not be able to restore the tank to its original shape.
* They should have a snap-tight lid, a screened overflow and a
filtered air inlet.

* If it fails, the 50 gallons will take down all the ceilings. The
float valve will be running and the damage will be enormous if there
is no-one in at the time. A no-brainer, IMHO.

/If/ its knackered, I agree. I got rather the impression it was still
sound though, just a support come adrift.
