While investigating another question, I began to suspect that my sump pump is not discharging far enough away. There are four pipes coming to the sump pit. After a heavy rain stopped, the one from the same side as the discharge would continue to drain for a day or so into the sump pit while other pipes pretty much dried.

Is there a way I can try first before digging (which would likely require removing brick pavers)? I read about dyed water for troubleshooting septic systems. Would that be a suitable approach? Anything in particular to use?

[UPDATE] I tried pouring 10+ gallon of water with tracer dyes into the sump pit, but I cannot see anywhere outside getting wet...
