The Pentair SuperFlo VS EC-342001 is a 1.5 HP variable-speed in-ground pool pump that Pentair has officially discontinued, with the SuperFlo VST as the current replacement. At our September 2026 check, it was listed on Amazon below the displayed list price. This review does not simply describe what the pump is. It answers the question that actually matters when looking at a discontinued product: is it still worth buying, at what price, for which buyer, and what are the honest risks of choosing it over the current model?
The specifications and owner feedback in this review are drawn from Pentair’s official product documentation and the Amazon listing for ASIN B00PKHX2BM, reviewed in September 2026. No hands-on testing was performed and no performance measurements were taken. Where sources conflict or information is unconfirmed, this review says so.

The Pentair SuperFlo VS EC-342001 is a capable 1.5 HP variable-speed pump that Pentair has officially discontinued, with the SuperFlo VST as its current replacement. At our September 2026 check, it was listed on Amazon below the displayed list price. Whether it makes sense to buy depends entirely on price: if the discount is significant compared with the VST, it can be a sound purchase for a compatible system. If the two are close in price, the current-production VST is the stronger choice. The discontinued status creates a real long-term parts and support question that buyers should weigh honestly.

Is the SuperFlo VS EC-342001 a good fit for your pool?
Good fit if
- Your pool system is already plumbed for a SuperFlo VS and you want a direct replacement
- The EC-342001 is available at a meaningful discount versus the current SuperFlo VST
- You want Pentair variable-speed quality and 3-speed programming at a below-list price
- You are comfortable with discontinued-model considerations on parts and long-term support
- Your automation system is RS-485 compatible and the VST's current-production status is not a priority at this price
Look elsewhere if
- The price difference between EC-342001 and the SuperFlo VST is small or nil
- Long-term parts availability and manufacturer support certainty are priorities
- You want the newest Pentair variable-speed model with current-generation controls
- Your automation integration requires VST-specific features
The most important thing to know first
Pentair's official website currently states: 'The SuperFlo VS Variable Speed Pump has been discontinued.' The recommended replacement is the SuperFlo VST. This is the defining fact about the EC-342001 right now, and no honest review of this pump can skip past it. You can verify this directly on the Pentair SuperFlo VS official page.
Discontinued does not mean the pump has failed or become unreliable. It means Pentair has stopped manufacturing it and that the VST is its current successor. The EC-342001 is still available through Amazon and some pool supply distributors. The question is whether buying a discontinued but still-new unit makes economic and practical sense for your pool.
The short answer: it depends on the price. If the EC-342001 is meaningfully cheaper than the current SuperFlo VST, it can be a rational purchase for a compatible system. If the two are close in price, the current-production VST is the more sensible choice because it carries full Pentair support without the parts-availability question that comes with any discontinued model over time. The table below makes this framework concrete.
| EC-342001 price vs SuperFlo VST today | Suggested approach |
|---|---|
| Much cheaper | Potentially worth buying if system is compatible and you accept discontinued-model risk |
| Moderately cheaper | Compare warranty and support terms carefully before committing |
| Similar or the same price | Buy the current SuperFlo VST - no reason to choose the discontinued model |
| More expensive | Skip - never pay more for a discontinued model |
Check current prices on Amazon and with your pool supplier. Prices change frequently; this framework applies to whatever prices you see today.
What EC-342001 means, and how it differs from 342001
The EC prefix on EC-342001 stands for ecommerce, designating the version of the 342001 sold through online retail channels including Amazon. Pentair uses EC- prefixes for products that are distributed through ecommerce rather than traditional pool dealer channels. The underlying pump is the same 342001, packaged and sold differently.
This distinction matters because some specifications, warranty terms, or included accessories can differ between dealer-channel and ecommerce-channel versions. Pentair's ecommerce products sometimes carry different warranty conditions. Confirm the warranty terms on the specific listing you are buying from before purchasing.
Specifications: what Pentair and Amazon confirm
The specifications below come from Pentair's product documentation and the Amazon listing, captured in September 2026. The motor is a TEFC (totally enclosed fan cooled) permanent magnet type, rated at 1.5 HP. Pentair lists THP (total horsepower) as 2.2 for the EC-342001. WEF (weighted energy factor) is listed as 9.0, which qualifies the pump for ENERGY STAR certification.
The pump operates on 115V or 230V at 50/60 Hz, making it compatible with standard US residential electrical. Weight is listed as 25.8 lb on the Amazon listing. Dimensions are listed as 12.5 in L × 12.5 in W × 15.5 in H. These figures are from the listing and should be verified against the pump's physical documentation.
RS-485 connectivity allows integration with compatible Pentair automation systems. Not every older home automation setup is RS-485 compatible, so check your existing controller before assuming the connection is available.
How the variable-speed system works in practice
The SuperFlo VS is a three-speed pump, not a continuously variable pump. You program three speeds using the digital keypad, and the pump runs at whichever speed is scheduled or manually selected. There is an override mode. The built-in 24-hour real-time clock lets you set different speeds for different time periods, which is the main tool for matching pump operation to daily pool needs.
In practice this means you might program a low speed for overnight circulation, a medium speed during the day, and a higher speed briefly when running a cleaner or booster. The three-speed design is simpler than a continuously variable pump but covers the main practical use cases for most residential pools.
The energy benefit compared with a single-speed pump running at full speed comes from running at lower speeds for most of the day. Pentair has cited energy savings of up to 80% compared with single-speed operation as a product claim for the SuperFlo VS family. Actual savings depend on your operating speeds, schedule, electricity rate, and system conditions. Variable-speed benefits are not automatic without correct programming. For more on how pump speed relates to runtime and flow, see our pages on pool pump flow rate and what size pool pump you need.
Programming and controls
The digital keypad on the SuperFlo VS is functional but basic by current standards. You access programming through the front panel, set three speed levels and their scheduled times, and configure the clock. Pentair's installation manual covers the programming sequence; most owners describe it as straightforward once you read the steps.
The controls do not have a touchscreen. The SuperFlo VST, the current replacement, also uses a digital control keypad with three programmable speeds and override - the same basic interface approach. The more meaningful differences between the two models are the VST's current-production status, full Pentair support, and updated mechanical seal, not the control surface.
RS-485 connectivity allows the pump to receive commands from a compatible Pentair IntelliConnect or IntelliTouch automation system. If you have one of those, you can control pump speed from the automation panel or app. If you do not have a compatible system, the RS-485 port is unused, but it does not affect the pump's standalone operation.
Flow rate and pump sizing
Like any pump, the SuperFlo VS does not deliver one fixed GPM. Actual flow depends on the speed setting you have programmed, plus your system's hydraulic resistance: pipe diameter, pipe length, fittings, valves, filter, heater, salt system, and any other in-line equipment.
Pentair publishes performance curves for the SuperFlo VS showing GPM at different head pressures for each speed. Those curves, not the 1.5 HP rating, tell you what the pump will actually deliver in your installed system. Do not size this pump based on horsepower alone.
Whether a 1.5 HP variable-speed pump is appropriate for your pool depends on your required flow for your target turnover time, your system's resistance, and the compatibility of your filter and other equipment. A pool with short runs of large-diameter pipe will operate at a different point on the pump curve than a pool with long, narrow plumbing. Use the pool pump runtime calculator and the sizing pages linked below to work out what your system needs.
Installation and compatibility
The SuperFlo VS is designed for in-ground residential pools and uses standard 2-inch plumbing connections. Confirm your existing plumbing matches before ordering. The pump is not typically used with above-ground pool equipment.
Voltage selection must be made before connecting power. The pump runs on 115V or 230V, and you configure this at the junction box per the installation manual. Follow the electrical requirements and use a qualified electrician for installation if you are not confident with pool electrical work. Pentair's documentation specifies wiring requirements; the listing does not substitute for reading the official SuperFlo VS installation manual.
The filter in your system must be able to handle the flow the pump delivers at your operating speeds. If your filter has a maximum flow rating, confirm that the pump's output at your typical operating speeds stays within that limit. The pool filter sizing page on this site explains how to check filter-to-flow compatibility.
Owner feedback patterns from Amazon
With 1,834 ratings at 4.4/5 as of September 2026, the SuperFlo VS has enough review history to identify patterns. These are themes from owner feedback, not statistical reliability data.
Recurring positives: owners most often mention quieter operation at lower speeds compared with their previous single-speed pump, lower electricity bills after switching, and straightforward programming once they had read the manual. Several owners mention long trouble-free operation over multiple seasons.
Recurring concerns: a portion of owners report failures or performance problems after several years of use, particularly around the motor or internal components. Some reviews mention difficulties with warranty claims, especially for EC-prefix ecommerce versions. There are isolated reports of noise from certain speed settings and impeller-related issues. Shipping damage is mentioned by a small number of reviewers.
These patterns do not translate to a failure rate. The pump has enough volume of satisfied owners to establish that many units run without issues. The durability concerns are worth noting because they are specific to years-in-service failures, not early defects, and the discontinued status means parts support may become more constrained over time.
When the discontinued status matters most
Discontinued means Pentair has stopped manufacturing the SuperFlo VS and that the VST is its successor. It does not immediately mean parts are unavailable or that the pump will stop working. Pentair typically continues to supply spare parts for discontinued pumps for a period after production ends, though the duration varies.
The practical risk is long-term: if the motor fails or a critical internal component needs replacement in several years, the availability of compatible Pentair parts may be more limited than it would be for a currently produced model. Aftermarket parts and compatible components may remain available, but with less certainty than a current-production pump.
For a buyer who finds the EC-342001 at a significant discount and whose system is compatible, the discontinued status is a calculated risk rather than a disqualifying factor. The pump is new, with a manufacturer warranty, and Pentair builds quality into this product line. The risk is about what happens if a major component fails in year four or five, not about immediate failure.

Common questions
Is the Pentair SuperFlo VS EC-342001 still a good buy even though it is discontinued?
It depends on the price. If the EC-342001 is meaningfully cheaper than the current SuperFlo VST and your system is compatible, it can be a rational purchase. If the two are close in price, the VST's current-production status makes it the more sensible choice. The discontinued status creates a real long-term parts question that is manageable at the right price.
What is the difference between the SuperFlo VS and the SuperFlo VST?
The SuperFlo VST is Pentair's current replacement for the discontinued SuperFlo VS. Both use a digital control keypad with three programmable speeds, override, and a 24-hour clock. The VST's key advantages are its current-production status with full Pentair support and an updated mechanical seal. The VS is discontinued but still available on Amazon at a potentially lower price - the decision comes down to whether that price difference justifies the discontinued-model risk.
What does EC-342001 mean?
The EC prefix indicates this is the ecommerce version of the 342001, sold through online retail channels including Amazon rather than through Pentair's traditional pool dealer network. The underlying pump is the same 342001. Warranty terms may differ between ecommerce and dealer-channel versions; confirm before buying.
How many speed settings does the SuperFlo VS have?
Three programmable speeds plus an override mode. You set each speed level and schedule using the digital keypad and the built-in 24-hour clock. This differs from continuously variable pumps, which offer a full range of speeds rather than three preset levels.
Does the SuperFlo VS work with pool automation?
Yes. The RS-485 port allows integration with compatible Pentair automation systems including IntelliConnect and IntelliTouch. If you do not have a compatible automation system, the pump operates independently using its built-in programming.
What size pool is the SuperFlo VS 1.5 HP suitable for?
Pool size alone does not determine pump suitability. The right match depends on required flow for your turnover target, your system's hydraulic resistance, and filter compatibility. A 1.5 HP variable-speed pump can serve a range of pool sizes depending on the system. Check our pool pump sizing page and runtime calculator for your specific numbers.
Is the Pentair SuperFlo VS still available to buy?
As of our September 2026 check, it was available on Amazon with 200+ units sold in the prior month. Availability may change as stock depletes since Pentair has discontinued production. Check the current Amazon listing for stock status.
