Call for high water bill. Upon inspection I found that the basement fill valve needed to be adjusted down. Adjusted it to proper level. Checked pressure on home, pressure reads at 50 psi at 3pm. After correcting fill valve toilet is no longer running. If fill valve overflows again we can return to replace valve, but toilet is fairly new. I recommend contacting your water service provider for a bill adjustment, as the toilet has been running a significant amount.
