Yes! It's not just a problem, it's an annoyance and it's costing you money on your water bill every month! In fact, a running toilet can cost you an upward of $80-$100 per month extra on your water bill! If a toilet continues to run after it is flushed, this usually means that there is a problem with the internal mechanics of the toilet. Often a little jiggle of the flushing valve will solve your problem, if not, the mechanics might need to be replaced. If the problem persists, call DCP right away to analyze the issue.
