Buying Guide: Key Considerations For Water Heater Drain Pumps
- Flow rate and head: Choose a pump with at least 300 GPH and a discharge head that meets your lifting needs, such as draining a heater or tank where water might need to be moved upward several feet.
- Submersibility: Most compact transfer pumps are non-submersible. Check if you need submersible operation for certain setups and recognize that submersible models require different protections.
- Hose compatibility: Look for standard 3/4″ GHT or garden hose adapters to ensure easy hookup with hoses you already own.
- Durability: Metal housing and copper motors offer longevity and better resistance to corrosion, compared to plastic housings.
- Safety features: Built-in on/off switches and thermal overload protection help manage operation safely, especially around water sources and electrical outlets.
- Portability: If you’ll move the pump between fixtures, consider models with handles and compact footprints.
