Purchased a Bladder water tank about 3 years ago at Menards. The tank failed a couple of weeks ago.
Of course I didn't have my reciept from 3 years and the tank had a 5 year warranty.
With the age of computers and electronic storage there was no way for them to verify, I purchased this tank from them and I still had the box it came in. There wasn't anything I could do and basically I was told there wasn't anythingn they could do to verify my purchase, so save your receipts for ever on the long warranty items.
