FAQs

Most commercial laundromats do. Many water authorities, including Sydney Water, require pre-treatment such as a lint trap or screen before laundry wastewater is discharged to sewer.

As a starting point the NP44AG suits one to three machines and the NP46AG suits three to five or more. Beyond that, sizing depends on drain flow rate, load profile and site constraints.

Check weekly on busy sites and empty when the basket or screen reaches about two thirds full. In practice most commercial laundries empty two to three times a week.

Requirements generally specify an aperture no greater than 4 mm for both the removable basket and the fixed screen, in materials that withstand high temperature and extreme pH.

Often, yes. Commercial laundry effluent typically leaves the machines at 38 to 45 degrees, and many authorities cap discharge at around 38 to 40 degrees.

Yes. Viking can supply trafficable or light-duty covers and risers for below-ground installations, and below-ground tanks have their own backfill requirements.

They work differently. A grease trap holds a volume of water so grease can separate out. A lint trap keeps flow low and screens fibres out, so no water storage builds up in the tank.

Pre-treatment requirements for commercial laundries are set by your local water authority. They vary by state and change over time, so confirm the current standard before you submit.
