Is a sewage ejector pump expensive to run?

Frequent cycling usually means a failing check valve, not heavy use — worth fixing before it burns the motor. At typical use it adds about $1.20 to a monthly electric bill at the US-average rate, but that swings from $0.84 in the cheapest states to $3.13 in the most expensive.

How many watts does a sewage ejector pump use?

Sewage Ejector Pump typically draws about 800 running watts. Because it has a motor or compressor, it briefly spikes to around 2,000 watts at startup, which matters for generator and breaker sizing but not for energy cost. Check the nameplate or label on your specific unit for its exact rating.

How can I lower the cost of running a sewage ejector pump?

Frequent cycling usually means a failing check valve, not heavy use — worth fixing before it burns the motor. You can also cut the cost by lowering your electricity rate — many utilities offer cheaper off-peak hours — or simply by running it fewer hours. Use the calculator above to see how changing hours per day or your rate moves the number.
