When I flush our toilet, the water (etc.) in the bowl rises very high, almost to the lip, before it all flushes down. It always flushes, and it doesn't sound like it's "straining" to flush, but it doesn't seem normal for the bowl level to rise so high before flushing. Could this have anything to do with the flapper valve, or is it more likely a clog somewhere below? Thanks in advance.
