The AISITIN material identified here is for an AS-3.5W solar fountain pump; it does not establish an AISITIN well-pump model. RPS, by contrast, sells solar well-pump kits and offers site-based sizing support. A decorative fountain and a well supplying a tank, livestock, irrigation, or a building need different equipment. Do not treat these brands as interchangeable for well pumping.
First decide what you need to pump
For a small decorative fountain
The available AISITIN document is an operation-instructions PDF for an AS-3.5W solar fountain product, hosted on AliExpress media. It is evidence for a fountain product, not for a solar well pump. Before buying, verify the exact current listing, intended use, dimensions, and how the panel and pump are arranged. The document does not establish current availability, updated specifications, performance, warranty, or support terms. Read the AISITIN AS-3.5W instructions.
For a well, tank, livestock, or irrigation supply
Start with a pump system designed and sized for well duty. RPS markets solar well-pump kits and provides a sizing process; its RPS 400 product page describes a wizard that considers well depth, latitude, and water needs and covers more than 100 RPS pump models. That figure is RPS’s own description of its model range, not an independent market count or performance validation. See RPS 400 and its sizing information.
The evidence here does not establish that AISITIN offers a well-pump model, so there is no supported head-to-head well-pump comparison. That is not proof that no such product exists; it means the identified AISITIN documentation cannot support a recommendation for well service.

What a fair well-pump comparison requires
Two systems can only be compared meaningfully when both are intended for the same job and sized to the site. A well pump’s duty point depends on the water level while pumping, the lift and pipe losses, the target pressure, and the amount of water needed. RPS’s own Water Assurance Guarantee also depends on accurate static-water-level, drawdown, and pressure estimates, as well as following its installation manual. Review RPS warranty and guarantee conditions.
- Well and lift: Record static water level, expected pumping level or drawdown, lift to the outlet or tank, and pipe diameter and length.
- Demand and delivery: Estimate daily volume and decide whether the pump fills storage, feeds a pressure system, or supplies a use such as irrigation or livestock.
- System design: Check pump and controller type, sensor inputs, battery compatibility, solar-panel count and wattage, wiring, pipe fittings, and any float controls or mounting hardware included with the exact kit.
- Site conditions: Consider available panel area and sun exposure, installation access, and whether water storage or batteries are part of the system.
- Service and terms: Confirm replacement-part access, technical support, warranty coverage, return conditions, shipping, and any requirements attached to sizing or installation guarantees.
RPS’s sizing wizard is a vendor tool, not independent validation that a proposed kit will meet a particular site’s needs. Provide accurate measurements and demand figures, and confirm that the proposed system is sized for them before purchase.

How to interpret RPS’s comparisons and specifications
RPS’s comparison page makes claims about its kits versus generic “Other Kits,” including construction, materials, controller features, sensors, inclusions, warranty, and support. It does not name AISITIN or report an independent head-to-head test. Treat those statements as RPS’s marketing claims, not evidence that a specific AISITIN model lacks a feature. Read RPS’s comparison page.
An older RPS specification sheet for the 200, 400, and 800 series illustrates that power, pump, controller, sensor, battery, panel, and fitting details vary by model. It should not be used as a current universal specification. Check the current documentation for the exact kit under consideration. View the RPS 200, 400, and 800 specification sheet.

Warranty, returns, and current product details
RPS’s warranty page, crawled in October 2026, states a two-year limited warranty and a 30-day money-back period, both subject to conditions; return shipping terms apply. Its Water Assurance Guarantee has additional requirements, including accurate well and pressure estimates, installation according to its manual, and giving RPS engineers an opportunity to resolve problems.

Which one should you choose?
- Choose an AISITIN fountain pump only for a small fountain application if the exact live model’s specifications fit your setup. The available instructions do not establish suitability for wells, potable water, household supply, livestock, or irrigation.
- Consider RPS for a solar well-pumping project by starting with site measurements, daily water demand, and the exact proposed kit’s current specifications and terms. RPS’s sizing support is a vendor service, not an independent performance guarantee.
- Do not choose between them as equivalent well-pump brands on the evidence available: the identified AISITIN product is a fountain pump, and no AISITIN well-pump documentation was established. No independent performance test or named-speaker quotation supports a broader comparison.
Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply.
