Choose Your Pump by Application
What the pump has to move matters more than the brand on it. Start with the job, then match flow to the head height you are actually lifting against.

Little Giant 1-Y Parts Washer Pump is a small oil-filled submersible pump from Little Giant's parts-washer family, designed for submerged parts washer service — pumping unheated Stoddard solvent and deodorized kerosene (UL-classified PJQU solvents). It is not intended for ponds, fountains, or general water use.
Key Specifications
- Flow: 205 GPH at 1' lift (Model 1 family)
- Motor: 1/150 HP direct drive, oil-filled, thermally protected; continuous duty
- Seal: Viton shaft seal rated for solvent service
- Discharge: 1/4" MNPT; nylon volute
- Construction: cast aluminum housing
- Cord: 6' power cord without plug, with conduit fitting for hard-wired parts-washer mounting
Which application is it right for?
Choose the 1-Y as a replacement pump for standard submerged parts washers; the 1-YS is the screened-intake version of the same pump. Looking for a fountain or water pump instead? See the Little Giant 1-42 or our full submersible pump lineup.
Shipping & Returns
Ships across Canada from stock — delivery typically takes 3 to 5 business days depending on province. Uninstalled units qualify for return within the applicable return period; contact us to arrange.
How do I size a pump for a waterfall?
Two numbers: the width of the spillway and the height you are lifting to. Wider spillways need more flow to look full, and every foot of rise cuts what the pump actually delivers.
Published flow ratings are measured at zero head - a pump rated 4,000 GPH delivers considerably less at eight feet. Send us the width and the height and we will size on real delivery rather than the number on the box.
What is a solids-handling pump and do I need one?
It passes debris rather than screening it out. If your pond is skimmer-fed, stocked with fish, or collects leaves, you want one - a screened pump in that setting clogs between visits.
For a clean statuary feature or a self-contained urn, solids handling is unnecessary and a compact pump is the better fit.
How much flow does a pond need?
A common working target is turning the volume over roughly once an hour on a stocked pond. Lightly stocked ornamental ponds tolerate less; heavily stocked koi ponds want more.
Waterfalls are sized differently - on flow per inch of spillway width rather than on pond volume. If you have both, size for whichever is the larger duty.
Can I use a Little Giant utility pump in my pond?
Generally not the right tool. The Little Giant utility and magnetic-drive units here are process and transfer pumps built for specific fluids and duty cycles, not continuous pond circulation.
If you are moving anything other than pond water, tell us what it is - seal and housing material compatibility matters and the wrong choice fails quickly.
Does the pump come with fittings or a fountain head?
Some do. The statuary and fountain kits arrive with a head ready to run. Most pond and waterfall pumps ship as the pump alone.
Check pump parts and accessories for fittings, or tell us your pipe size and we will include what you need.
Should I take the pump out for winter?
It depends whether the feature runs through winter. A pump left in a pond that freezes solid around it will be damaged.
If you are shutting down, the pump comes out, gets cleaned and is stored somewhere above freezing. If you are running through, we will advise on what the setup needs - ask before freeze-up.
