Ideal For Water Features Large backyard waterfalls Long streambeds (70–120+ ft) Wide waterfall spillways High-volume decorative features Pond Systems Large koi ponds & water gardens Pond skimmer boxes Pump vault installations Pondless waterfall reservoirs Installation & Maintenance Submersible only: Keep pump fully submerged during operation. Dry running will overheat the motor. GFCI required: Must be connected to a properly grounded GFCI-protected 120-volt outlet. Tubing: Use 2”–3” tubing for maximum flow and minimal friction loss. Skimmer & vault use: Compact 10” diameter fits standard skimmer boxes and pump vaults. Ideal placement protects the pump from debris. Intake screen: Clean the intake screen periodically to maintain full performance. Inspect for large debris accumulation. Seasonal removal: Remove and store pump indoors before freezing temperatures to maximize pump life. Hard water: In hard-water areas, a brief soak in a diluted vinegar solution once per season removes mineral scale buildup. Frequently Asked Questions What is the maximum flow rate and head height of the TH750? The EasyPro TH750 delivers a maximum flow rate of 6,000 GPH (at zero/minimum head) and has a maximum head height of 46 ft. At real-world head heights, expect: 5 ft head: 5,700 GPH 10 ft head: 5,340 GPH 15 ft head: 4,980 GPH 20 ft head: 4,740 GPH For best results, use 2” or 3” plumbing to minimize friction losses and ensure maximum volume reaches your waterfall spillway. To estimate total head, add the vertical rise from pump to spillway plus an allowance for pipe friction (~1 ft per 10 ft of pipe as a rough guide). What type of motor does the TH750 use, and how efficient is it? The TH750 uses a direct drive motor — a rugged, proven design built for continuous-duty high-flow applications. The motor housing is corrosion-resistant stainless steel; the pump casing is abrasion-resistant fiber-reinforced plastic. Power consumption ranges from 600 to 910 watts (6.0–9.9 amps at 115V) depending on operating conditions. Size your GFCI circuit for the maximum draw of approximately 910W / ~9.9A. The TH750 is designed for 24/7 continuous operation and includes built-in thermal overload protection with automatic self-reset to prevent damage from overheating. Is the TH750 a solids-handling pump? Yes. The TH750’s vortex design allows it to pass debris up to 3/8” × 1” in size without clogging. This makes it well-suited for use in pond skimmer boxes and pump vaults where fine sediment and small organic debris may bypass primary filtration screens. For best performance, periodically check and clean the intake screen to prevent fine debris accumulation that can reduce flow over time. Is the TH750 fish-safe and suitable for koi ponds? Yes. The TH750 is fish-safe and completely oil-free. The stainless steel motor housing and fiber-reinforced plastic casing contain no substances that can leach toxins into pond water. The high-volume circulation the TH750 provides helps maintain dissolved oxygen levels essential for koi health and aquatic plant vitality. Note: The TH750 is not approved for use in swimming pools or salt water. For salt-water applications, contact EasyPro for appropriate product recommendations. What is the discharge outlet size, and what fittings are compatible? The TH750 features a 2” FPT (female threaded) discharge outlet. For most installations, 2” Schedule 40 PVC or flexible PVC pipe is used. A 2” male-threaded union fitting is a recommended addition to allow pump removal without cutting pipe. EasyPro recommends using a 2” check valve assembly to prevent backflow into the pump basin when the pump is shut off — important for pondless waterfall and large koi pond installations where backflow could drain the skimmer or vault. How do I maintain the TH750 for maximum lifespan? The TH750 is a low-maintenance pump, but a few routine steps will extend its life: Intake screen: Check and rinse periodically. Heavy debris accumulation reduces flow and forces the motor to work harder. Hard water: In areas with significant mineral content, a 30-minute soak in a diluted vinegar solution (1 part vinegar to 3 parts water) once per season dissolves calcium scale from the impeller and housing. Winter storage: Remove the pump before sustained freezing temperatures. Store in a bucket of water in a frost-free area to prevent seal damage from freeze-thaw cycles. Thermal protection: The TH750 includes built-in thermal overload protection with automatic self-reset. If the pump stops unexpectedly, check for debris blockage and allow the motor to cool before restarting. What cord length options are available for the TH750? The TH750 is available in three cord length configurations: TH750 — 20 ft cord (base model, sold on this page) TH750-50 — 50 ft cord TH750-100 — 100 ft cord For large waterfall and stream installations where the pump vault is located far from the nearest GFCI outlet, the 50 ft or 100 ft models may be preferable. Contact us at (765) 508-4352 if you need the longer cord variant. What pump should I consider if I need more flow than the TH750? The TH750 is the top model in EasyPro’s TH Series. For higher-flow applications, EasyPro offers two higher-volume pump families: EasyPro TB Series: TB8000, TB10000, TB12000 — submersible high-flow pumps for very large waterfalls and stream systems EasyPro TM Series: TM13500, TM17500 — for the most demanding large-scale features requiring 13,000+ GPH Call or text us at (765) 508-4352 and our pond specialists can help you size the right pump for your specific head height, flow requirement, and plumbing configuration. How does the TH750 compare to the TH250 and TH400? The EasyPro TH Series spans four models in the 115V submersible line: TH150: 3,100 GPH | 1/4 HP — compact ponds, small waterfalls TH250: 4,100 GPH | 1/3 HP — medium waterfalls, mid-length streams TH400: 5,100 GPH | 1/2 HP — large ponds, wide spillways TH750 (this pump): 6,000 GPH | 1 HP | 46 ft max head — the largest TH Series model; for streams 70–120+ ft and tall or bold waterfall features All four models share the same stainless steel motor housing, fiber-reinforced plastic casing, vortex design, direct drive technology, and 2-year warranty. The step up from TH400 (5,100 GPH) to TH750 (6,000 GPH) represents roughly 18% additional flow for applications where that output difference matters. Can the TH750 be run externally (out of water)? No. The TH750 is a submersible pump only. Its direct drive motor is cooled by the water it sits in; operating the pump out of water will cause rapid overheating, damage the motor seals and impeller, void the 2-year warranty, and likely destroy the pump permanently. For external pump applications, EasyPro offers a separate external pump product line (EX Series). Contact us at (765) 508-4352 for guidance on selecting the right external pump for your installation.
