Before You Choose
Before You Choose
Use these points to compare the water, installation and operating requirements before choosing a model.
Start with water free of debris that could block or damage the pump. Compare drainage levels, flow at your working head, hose size and level-control requirements.
Compare Drainage Levels
Some models leave a lower water level than others. Starting water level and automatic switch-off level are separate specifications.
Match the Installation
Check flow at your working head, hose size and space for level controls.
Explore the Applications
Start with pool drainage, rainwater transfer, tank emptying or clean-water cleanup. Check the water condition before using a clean-water model in a flooded area.
Key Applications
Where these families may fit within their published limits.
Application suitability depends on the liquid, solids, required duty point, installation/control method and exact product configuration.
Common Questions
Questions to Check Before You Choose
Which YARDPUMP models are for clean water?
The clean-water range includes QDX-PT, QDX-PH, QDX-PA, QDX-PP and QDX-SC. Each has its own power options, drainage level and controls.
Is maximum flow enough to choose a pump?
No. Look at the flow available at the lift and hose resistance in your installation. Maximum flow is measured at one end of the performance curve; it is not the flow at maximum head.
