Sounds like a definite problem with the flush valve. To narrow down possibilities - When you step on the foot pedal to flush, does the pedal quickly return to the fully up position? Have you tried pulling it fully up by hand or lifting it with your foot?

If the pedal doesn't come all the way up, the valve won't close and water will continue to flow. If the pedal does come all the way up and water still flows, the valve needs rebuilding or replacement.

Considering the age of your rig, it may also be something as simple as giving the pedal/valve assembly a thorough cleaning and a shot or two of lubricant.

Good luck, and welcome to the forum !

It could be too much water pressure, a bad or sticking flush valve

The flush valve does two things, it opens the bottom so the waste falls to the tank and two it turns on the valve to allow the water in. Depending on the type of toilet the valve assembly is a fairly easy and straight forward one to repair. I would start by taking the valve apart and inspecting all the working parts. I would go on the mfg. web site and pull up the valve assembly diagram. I would think that when you push the peddle the fresh water valve stays open maybe it has a built up on it.
