Description
The EasyPro TH250 TH Series Waterfall & Stream Pump delivers 4,100 GPH through a 2” FPT outlet for powering medium-to-large waterfalls, stream features, and koi pond circulation. A direct-drive motor in a corrosion-resistant stainless steel housing drives an abrasion-resistant fiber-reinforced plastic pump casing with a vortex impeller designed to pass small debris without clogging. Built-in thermal overload protection guards against motor burnout during demanding continuous-duty applications. Compact enough to fit inside most pond skimmer boxes. Available with 20 ft, 50 ft, or 100 ft power cord. 2-Year Warranty.
Why Choose the EasyPro TH250?
- 4,100 GPH at open flow: One of EasyPro’s most popular direct-drive pumps — ideal for medium waterfalls, long streambeds, and koi pond skimmer applications requiring sustained high flow.
- Direct-drive motor with stainless steel housing: The direct-drive design delivers raw pumping power in a corrosion-resistant stainless steel motor casing engineered for continuous-duty, year-round operation.
- Vortex impeller design: EasyPro’s wear and clog-resistant vortex impeller allows small debris to pass through the pump without clogging or impeller contact — reducing maintenance intervals significantly.
- Fiber-reinforced plastic pump casing: Abrasion-resistant FRP construction resists wear from debris-laden water over years of continuous operation.
- Built-in thermal overload protection: If the motor overheats due to a blockage or excessive head, the thermal overload trips to prevent burnout — the pump resets automatically when it cools.
- Compact skimmer-ready design: The TH250’s upright footprint fits inside most pond skimmer boxes and pump vaults without modification. EasyPro calls the TH Series one of the industry’s best-selling skimmer pumps.
- 2" FPT discharge: The 2” female pipe thread outlet connects directly to standard 2” pond fittings, valves, and check valves — no reducers required for most waterfall builds.

Frequently Asked Questions
What is the maximum flow rate and vertical lift of the EasyPro TH250?
The EasyPro TH250 delivers a maximum of 4,100 GPH at open flow (0 ft head). Maximum head height (vertical lift) is 28–30 ft. For optimal efficiency, plumbing should be sized at 2 inches to match the pump’s 2” FPT discharge outlet — reducing to smaller pipe restricts flow and increases back-pressure.
See the performance chart in the gallery for flow rates at each head height. The TH250 is ideal for waterfalls and streams with a total head height of 15 ft or less, where it delivers 2,200+ GPH (verify against chart).
Can the EasyPro TH Series pumps handle debris and solids?
Yes. The TH250’s vortex impeller is specifically designed to resist clogging by allowing small debris to pass through without making contact with the impeller blades. This is a key advantage of the vortex design over standard centrifugal impellers, which can clog when debris reaches the blade surfaces.
For best results, place the TH250 inside a pond skimmer box or pump vault so larger debris is screened before reaching the pump. The included pre-filter intake screen provides additional protection.
How energy-efficient is the TH250 for 24/7 continuous operation?
The TH250 is a direct-drive pump that draws 445–500 watts (min/max across operating head heights) at 2.6–4.2 amps. At average residential electricity rates ($0.12/kWh), continuous operation costs approximately $468–$526 per year.
The TH Series is engineered for efficiency within the direct-drive pump category — delivering high GPH-per-watt compared to other direct-drive pumps at this flow rate. For significantly lower operating costs, consider a variable-speed or synchronous electronic pump such as the Oase AquaMax Eco Premium series. For raw continuous-duty reliability at 4,100 GPH, the TH250 is a leading choice.
Is the EasyPro TH250 safe for koi ponds and fish-heavy ecosystems?
Yes. The TH250 is oil-free — the stainless steel direct-drive motor uses no oil lubrication that could contaminate pond water. The fiber-reinforced plastic pump casing and stainless steel housing are both safe for fresh-water pond applications with fish and aquatic plants.
Note: The TH250 is not approved for use in swimming pools or salt water. For pond applications, plug into a properly grounded GFCI-protected outdoor outlet.
Can this pump be used horizontally or vertically?
The TH250 is designed primarily for vertical (upright) installation in a skimmer box or pump vault with the intake submerged. Vertical orientation keeps the double mechanical seals lubricated and cooled during operation.
External (inline) installation in a pump vault is also possible and is a common professional configuration. In either case, the pump must not run dry — the intake must remain submerged during operation.
What maintenance is required for the EasyPro TH Series pump?
The TH250 is designed for minimal maintenance:
- Periodically inspect and rinse the intake screen to remove accumulated leaves, algae, and debris
- Rinse the impeller assembly with fresh water at the start of each season
- In hard-water areas, a brief soak in a diluted vinegar solution once per season removes mineral scale from the pump body
- In freezing climates, remove the pump before sustained freezing temperatures and store submerged in a bucket of water indoors to keep seals from drying out
