Gray Water Laundry Pump

Q. "What is gray water?"
A. At its most basic definition, graywater (sometimes noted as greywater, grey water, or gray water) is the used water that goes down your home drains, with the exception of toilet water. This includes wastewater generated by laundry, dishwashing, hand washing, bathing and other washing. While this may be the dictionary definition of graywater, for the purposes of recycling graywater, some plumbing codes define gray water as only water discharged from lavatories, bathtubs, showers, clothes washers, and laundry trays and specifically exclude wastewater from kitchen sinks or dishwashers from their definition of gray water. Once water has been through a toilet, water closet, urinal, or in any way comes in contact with human waste, it is always considered sewage or black water. We recommend confirming with your local code authorities if you are unsure if your application works within code definition of gray water.

Q. "Does this laundry sink pump need to be vented?"
A. Per the manufacturer's installation instructions, this unit does need to be vented and has been designed with a vent connection on the top of the pump to allow for connection to a two-way air venting system. The manufacturer recommends using 1-1/2" PVC or ABS pipe, which is easily available in most localities, but as always, consult with a trusted local professional and your code authorities to confirm your installation meets all code requirements for your area.

Q. "What is the best way to connect the side inlets?"
A. The manufacturer recommends using 1-1/2" PVC schedule 40 female adapters. If either side inlet is not being used, make sure that the end cap is properly screwed in so the unused inlet is completely sealed.

Q. "Okay, I'm really interested in this pump, but does this include everything I need for my installation?"
A. This is the pump only. Due to the variables in home plumbing, local plumbing codes, and the option of having multiple fixtures connected to this pump, you may need a few more items to complete your installation. Once you confirm with your local code authorities, you may need 1-1/2" PVC or ABS pipe and fittings for the venting and discharge connections. We have found that PVC and ABS pipe is usually most easily and economically purchased locally. Depending on how many fixtures you choose to attach to this pump, you may also need 1-1/2" PVC schedule 40 female adapters. If either side inlet is not being used, simply make sure that the included end cap is properly screwed in so the unused inlet is completely sealed.
