Free home & diy tip: Fill valve and float (step 2 of 4 from "How a Toilet Actually Works").
After the flush, fill valve opens — refills tank and sends a refill tube trickle into the overflow pipe to restore the bowl seal.
Float (cup or ball) rises and shuts the valve at the waterline mark. High waterline = waste; low = weak flush.
Pro tip: Food coloring in tank, wait 15 min without flushing — color in bowl means flapper leak.
