Little Giant WRSC-6 Compact 'Drainosaur®' Utility Drain Pump (506065)

Description
Little Giant WRSC6 is a Gray Water - Drain Lift Pump. The Little Giant Drainosaur is a compact unit, it includes a 3 1/2 gallon (13.2 L) tank, which is only 10 1/2" (26.6cm) high. Automatic submersible pump with mid-level activating switch; 8' (2.4m) power cord. Basin is IAPMO approved.

Gray Water is wastewater composed of wash water from kitchen, bathroom, and laundry sinks, tubs, and washers. Gray Water is different from sewage, which is organic waste or wastewater from humans, animals or plants or household operations.

Compact Drainosaur Pump - Fluid Systems Design Parameters

For "gray wastewater" applications at home or at work, The Drainosaur is perfect for laundry tray sinks, bar sinks, fountains, larger condensate applications, washing machines and other basement pumping projects.

If you need an 1-1/2" check valve, here are two: CV150C and CV2N1 for your selection (a check valve is required on the discharge line of this pump/tank).

This simple installation saves you time and money.

WRSC6 - Little Giant - 3.5 Gallon Compact Utility Drain Pump System allows for the convienience of easily installing a sink, without breaking concrete to create a drain. No main stack vent connection is required per National Standard Plumbing Code - Section 11.7.9 - check your local codes.

About Air Admittance Valves (AAVs). Can I Use One?

Can I use an AAV on a Compact Utility Drain Pump?

No - It is not recommended by the manufacturer.

We put this information about AAV's here because it is a Frequently Asked Question and people have been known to use AAV's on Drain Pumps.

We do not suggest or recommend that an AAV be used on this application.  Typically  Compact Utility Drain Pumps are vented through the roof, we refer you to your local codes for proper venting of any Compact Utility Drain Pump.

About Air Admittance Valves (AAVs)
Plumbing drain, waste and vent systems, known as DWV, consist of the drain pipes that provide a network for the removal of waste and the vent pipes that prevent traps from siphoning and maintain an equalized pressure. The DWV system uses gravity and air displacement throughout the piping network to function and breathe. In a simplified example, water in an inverted bottle without an air hole will glug and gasp when emptied. Adding an opening to the bottom of the bottle will turn the process into an efficient, steady flow because the bottle "breathes."

EVERY drain needs a trap. EVERY trap needs a vent.
To prevent sewer gases from being released into the structure, plumbing code requires a trap to be installed at every fixture. A trap is a U-shaped bend of pipe filled with water that acts as a barrier between the structure and the sewer system. Trap seals can only be compromised under two conditions - high sewer pressures and water siphons, in both cases vents prevent this from happening.

Under high sewer pressures without a vent, trap seals will allow sewer gases to escape and enter the structure. This happens when the sewer pressure is greater than the pressure from the column of water in the trap. A vent will keep the sewer and atmospheric pressures equalized to maintain the trap seal.

Water moving through pipes can create a negative pressure or a siphon. The siphon will pull the water from a trap, leaving a clear path for sewer gases to enter the structure. A vent will prohibit siphoning, maintaining the trap seal.

Air Admittance Valve?
Air Admittance Valves (AAVs) open and close in conjunction with normal DWV system operation, effectively eliminating the need for secondary vent pipes. An AAV provides an alternative to secondary venting when utilized within the scope of model plumbing codes, referenced standards.

AAVs provide the ideal venting solution for island sinks, remote bathroom groups and remodeling jobs by eliminating the need to tie into a stack vent.

AAVs are often more economical than running vent pipe in new construction because they reduce the added need for supplies and labor.
