Q: What is greywater?
A: Untreated wastewater from wash basins, showers, floor drains and appliances containing fibres and solids no larger than 10 or 35 mm
Q: What is greywater?

Q: What is greywater?
A: Rainwater – it looks grey when it flows on built up surfaces
Q: What is free passage and why is it important?
A: Free passage is used only to define the type of wastewater by particle or solids size and has no impact as such on the pump hydraulics
Q: What is free passage and why is it important?
A: Free passage is another way of describing input or output pipe diameter
Q: What is free passage and why is it important?
A: Free passage describes the particle or solids size that can pass freely through the pump hydraulics and is important to avoid clogging in the pump
