Hello,

Within the last week, our toilet has started to run between flushings. The odd thing is that it drains twice with each flush. It then fills, but will continue to run. I checked the chain, float ball and made adjustments. This will not stop. Any suggestions? RD

Running, like as in refilling? This would be a bad flapper or seal. Repacing a flapper is easy and cheap but feel the seat it lays on for nicks or junk, it has to be smooth. Make sure after a flush that there is a bit of slack on the chain going to the flapper, no slack and the flapper is being helld a tiny bit above sealing
