What's the quietest/most efficient sump pump?

Sump Pump Noise and Efficiency

A user is looking for a quiet and efficient sump pump for a new setup. The current NewJet 2300 pump is too loud. The tank size is 18"x18"x36".

Pump Recommendations

Eheim compact + pumps are suggested as quiet options. Deltec HLPs and Red Dragons are also mentioned for quietness, but may be overkill. Eheim compacts and NewJets are generally considered good. Eheim Compact+ with variable output rated at 1500-3000lph is mentioned as a quiet pump.

Troubleshooting Noise

One user suggests checking if the NewJet 1700 is rattling against anything or if anything is caught in it. Another user experiencing noise with an Eheim compact 5000+ is considering soundproofing the sump cabinet. The vibration is being amplified because the tank is on a wooden floor and the cabinet is a big empty wooden box.

Soundproofing Tips

A rubber mat under the sump can help reduce vibration. Expanded polystyrene or rubber/neoprene sheeting can be used for soundproofing, but air circulation and fire risk should be considered. Insulating the cabinet is also suggested. A user found Tunze Silence Pump quieter than Eheim 1262. Another user suggests a rubber mat under the sump to stop vibration.
