Frequently asked questions

Common questions about Drain Pump from 3G Electric.

How do I size a drain pump system for my application?

Consider the total fixture units feeding the pump, required discharge head (vertical lift plus pipe friction), and liquid temperature. High-temp models handle up to 200°F, while general-purpose units suit typical sink drainage. Check the pump's GPH rating at your head height to ensure adequate capacity.

Which brands of drain pump systems does 3G Electric stock?

We stock drain pump systems and replacement pumps from Liberty Pumps, Little Giant, Zoeller, Saniflo, Hartell, Dayton, and Flotec. This range covers general-purpose, high-temp, and Wi-Fi-enabled models, so you can find the right fit for residential, commercial, or industrial drainage needs.

Can I get replacement pumps for my existing sink drain pump system?

Yes. We carry replacement pumps for sink drain pump systems from the brands we stock. When ordering, have your current pump's model number and specifications ready so we can match the correct replacement for your system.
