Superior Electric WP700 Submersible Water Pump Review: The Tiny Titan for Your Tile Saw

There’s a specific, low-level anxiety that every contractor or dedicated DIYer knows. It’s the moment you’re halfway through a critical tile cut, the diamond blade is screaming, and the once-steady trickle of cooling water sputters and dies. The blade overheats, the cut goes sideways, and a perfectly good piece of porcelain is now destined for the scrap heap. I’ve been there more times than I care to admit. The cheap, nameless pumps that often come bundled with wet saws are notoriously unreliable. They clog, they burn out, and their flow is often inconsistent. This isn’t just an annoyance; it costs time, money, and materials. That’s what sent me on a mission to find a replacement pump that was small, tough, and dependable—a true workshop workhorse. The search led me straight to the Superior Electric WP700 Submersible Water Pump, a compact unit promising consistent performance for tools and more.

What to Consider Before Buying a Submersible Utility Pump

A submersible pump is more than just an item; it’s a key solution for moving water from one place to another without complex external plumbing. Whether you’re keeping a tile saw blade cool, creating a tranquil backyard fountain, or draining a small flooded area, the principle is the same: you need reliable, continuous water flow. The primary benefit of a submersible design like this is its simplicity and efficiency. It uses the very water it’s sitting in to cool itself, allowing for longer run times, and its direct-drive mechanism minimizes energy loss. For a workshop, this means less downtime and better cutting results. For a pond or fountain, it means a healthier aquatic environment and a more beautiful water feature.

The ideal customer for this type of compact pump is someone facing a need for low-volume, continuous water circulation in a confined space. This includes tile setters, stonemasons, hobbyists with small water features, or anyone needing to power a small hydroponics system. It’s a specialist tool for a specific job. On the other hand, it might not be suitable for those who need to move large volumes of water quickly or overcome significant vertical height. If you’re trying to drain a swimming pool, power a large waterfall, or run a whole-house irrigation system, the Superior Electric WP700 Submersible Water Pump would be vastly underpowered. In those cases, you’d need to look at high-horsepower centrifugal pumps or heavy-duty sump pumps.

Before investing, consider these crucial points in detail:

• Dimensions & Space: A submersible pump has to fit inside its water source, be it a tile saw tray, a fountain basin, or a 5-gallon bucket. The WP700’s compact profile (2-3/4″ x 1-7/8″ x 2-1/4″) is one of its greatest assets, allowing it to be easily hidden and fit in tight quarters. Always measure your available space before purchasing to ensure a proper fit without impeding water intake.
• Capacity/Performance: This is defined by two key metrics: flow rate (Gallons Per Hour/GPH) and maximum lift height (also called ‘head’). The Superior Electric WP700 Submersible Water Pump is rated for 150 GPH with a max lift of 43 inches. This means it can push water up a tube 43 inches high before the flow stops. It’s crucial to match these specs to your needs; a pump too weak won’t get the water where it needs to go, while one that’s too powerful can create splashing and waste energy. You can see its full performance specifications here to ensure it matches your project’s demands.
• Materials & Durability: The environment a pump lives in can be harsh. For a tile saw, it’s a slurry of abrasive grit and minerals. For a pond, it’s constant submersion. The WP700 uses a corrosion-resistant plastic housing, which is ideal for these applications as it won’t rust like metal components might. Look for robust materials and sealed motor housings to guarantee a long, dependable service life.
• Ease of Use & Maintenance: A good utility pump should be a set-it-and-forget-it tool. Features like suction cup feet for stable mounting, a long power cord (the WP700 has a 6-foot grounded cord), and an adjustable flow rate add significant value. For long-term care, consider how easy it is to access and clean the intake and impeller. A tool-free design for cleaning is always a major plus.

This little pump is a fantastic specialist, but it’s important to understand the broader landscape of water-moving equipment.

While the Superior Electric WP700 Submersible Water Pump is an excellent choice for its intended applications, it’s always wise to see how it stacks up against the competition. For a broader look at all the top models, from small utility units to massive pool circulators, we highly recommend checking out our complete, in-depth guide:

First Impressions: A Compact Powerhouse in Red

Pulling the Superior Electric WP700 Submersible Water Pump out of its straightforward packaging, the first thing we noticed was its surprising density. For such a small unit, it has a satisfying heft that speaks to a solidly built motor and housing. The bright red plastic casing is thick and feels durable, not at all like the brittle plastics found on cheaper alternatives. There’s no assembly required; it’s ready to go right out of the box. The three suction cups on the bottom felt pliable yet strong, suggesting they’d get a good grip on the smooth plastic of a tile saw’s water tray.

The 6-foot power cord is a welcome feature, providing ample length to reach a GFCI-protected outlet without needing a risky extension cord near water. Crucially, it’s a 3-prong, grounded plug—an essential safety feature for any tool that operates in water. We also immediately noticed the flow control dial on the front intake. It has a simple lever that slides from a minimum to a maximum setting, offering a tangible way to fine-tune the water output for the task at hand. It’s a simple, robust design that feels built for function over flash, which is exactly what we look for in a workshop tool. This initial quality impression immediately set it apart from the flimsy, unbranded pumps it was bought to replace. You can check the latest price and availability for this impressive little unit.

Deep Dive: The WP700’s Performance Under Pressure

A pump’s true worth is only revealed when it’s put to work. We didn’t just bench-test the Superior Electric WP700 Submersible Water Pump; we integrated it into our workflow, using it as the primary pump for an MK-370 tile saw during a bathroom renovation project. This provided a real-world crucible of dirty water, long run times, and the absolute need for consistent performance. Its performance was not just adequate; it was exceptional for its class.

Unpacking the Magnetic Drive Heart

At the core of the Superior Electric WP700 Submersible Water Pump is its magnetic drive system. Unlike direct-drive pumps where a sealed shaft connects the motor directly to the impeller, a magnetic drive uses a set of magnets to turn the impeller without any physical connection. This design has two enormous benefits for this application. First, it eliminates the need for a shaft seal, which is a common point of failure in cheaper pumps, especially when exposed to abrasive particles from tile and mortar. With no seal to wear out, the motor is hermetically protected from the water, leading to a significantly longer lifespan.

Second, this design is incredibly energy efficient and quiet. We measured the power consumption, and it stuck right around the advertised 12 watts—a minuscule amount of electricity. During operation, the pump is virtually silent. The only sound you hear is the gentle hum of the magnetic coupling and the flow of water itself, a stark contrast to the rattling chatter of some budget pumps. This oil-free magnetic system is also what makes it safe for use in small ponds or fountains with fish or plants, as there’s no risk of lubricant contamination. This dual-purpose capability is a feature that really sets it apart in the utility pump category. After over 20 hours of intermittent use cutting tough porcelain tile, the pump’s housing was barely warm to the touch, a testament to its efficient, cool-running design.

Real-World Flow Rate and Lift Performance

Specifications on a box are one thing; performance in a murky water tray is another. The advertised 150 GPH and 43-inch maximum lift height felt accurate in our testing. For our tile saw, which required a lift of about 14 inches from the tray to the blade guard, the flow was robust and easily managed. This is where the adjustable flow rate knob becomes an indispensable feature. When making long, slow cuts on thick porcelain, we could dial the flow up to maximum to ensure ample cooling and dust suppression. For more delicate cuts on ceramic or glass mosaic tiles, we could dial it back to prevent excessive splashing that could obscure our cutting line.

The control is simple but effective, offering a meaningful range between its minimum and maximum settings. At full power, it delivered a steady, generous stream of water that coated both sides of the diamond blade evenly. At its lowest setting, it provided a gentle trickle, perfect for keeping things damp without creating a mess. We found the sweet spot for most tile cutting to be around 75% of its maximum flow. This consistent delivery is the key to preventing blade glazing, reducing chipping, and ultimately achieving cleaner, more professional cuts. The reliability we experienced gives us the confidence to recommend you invest in this dependable pump for your own workshop.

Built for the Grind: Durability, Installation, and a Hidden Feature

The workshop is a hostile environment, and a tile saw’s water tray is ground zero. It’s a gritty soup of abrasive particles that can shred the internals of a lesser pump. The Superior Electric WP700 Submersible Water Pump‘s hard plastic housing and screened intake held up beautifully. The intake screen has fine enough slots to prevent larger chips from getting sucked in while still allowing plenty of water flow. After days of cutting, we saw no signs of undue wear on the housing.

Installation was effortless. The suction cups gripped the bottom of the plastic tray tenaciously, holding the pump firmly in place both vertically on the side wall and horizontally on the floor of the tray. This stability is crucial, as a pump that wanders can have its intake blocked. During our initial setup, we discovered a brilliant—and completely undocumented—feature, which was later confirmed by feedback from other users. The pump appears to come with only a large hose connector. However, if you pop the front intake cover off (as you would for cleaning), the large connector slides right off, revealing a smaller, narrower connector underneath. This was a fantastic discovery, as it allowed us to get a much tighter, leak-free fit with the standard tubing on our tile saw without needing adapters or clamps. It’s a thoughtful piece of design that many might miss, and as one user noted, the lack of documentation is a small drawback, but the functionality it adds is a huge plus.

What Other Users Are Saying

Our positive experience with the Superior Electric WP700 Submersible Water Pump is mirrored by many other users who have put it to the test. The general consensus is one of surprise and satisfaction with the power and reliability packed into such a small frame. A particularly insightful piece of feedback, which we confirmed in our own testing, centers on the hose connector. One user pointed out, “The large hose connector comes off when you open the unit. And you can slide the smaller hose connector that comes with it, in place.” This “hidden” feature is a common point of praise, allowing for greater versatility with different hose sizes.

This same user also noted a minor critique that we share: the unit does not come with any internal filter sponges. While the external screen does a good job of stopping large debris, a fine sponge could offer another layer of protection for the impeller. However, we found that with periodic cleaning—a simple process of popping the front cover and rinsing the impeller cavity—the pump operated flawlessly even in very gritty water. For the price and performance, most agree that this is a minor issue that is easily managed.

How Does the Superior Electric WP700 Compare to the Alternatives?

In the world of pumps, application is everything. Comparing the specialized Superior Electric WP700 Submersible Water Pump to heavy-duty pool or pressure washer pumps is like comparing a scalpel to a sledgehammer. While they all fall under the “pumps” category, they are designed for vastly different tasks, power scales, and environments. Understanding these differences is key to choosing the right tool for your specific job.

1. XtremepowerUS 1.5HP 2-Speed Pool Pump

The XtremepowerUS pump is an entirely different class of machine. With a 1.5 horsepower motor, it’s designed to circulate thousands of gallons of water in an above-ground swimming pool. Its flow rate is measured in gallons per minute (GPM), not gallons per hour, and its power consumption is orders of magnitude higher than the WP700’s 12 watts. Someone would choose this pump for its intended purpose: pool filtration and circulation. It is far too large, powerful, and expensive for use with a tile saw or small fountain. For its niche, the Superior Electric WP700 Submersible Water Pump is the more precise and economical tool.

2. AR ANNOVI REVERBERI SRMW22G26-EZ Replacement Pump

This AR ANNOVI REVERBERI unit is a replacement pump head for a gas-powered pressure washer. Its key metric isn’t just flow (2.2 GPM), but pressure, rated at a powerful 2600 PSI. The WP700 produces negligible pressure; its job is simply to lift water. The AR pump’s purpose is to create a high-velocity jet for cleaning. It cannot be submerged and is designed to be driven by a gasoline engine. This is a specific replacement part for a power tool, and it serves no purpose in a low-pressure, continuous flow application where the WP700 excels. There is no crossover in their use cases.

3. Doheny’s 1.5 HP Pool Pump

Similar to the XtremepowerUS model, the Doheny’s pump is a high-capacity unit built for above-ground swimming pools. It boasts an 83 GPM flow rate and a powerful 1.5 HP motor, designed for the heavy lifting of pool water filtration. It features large 1.5″ and 2.5″ threaded connections for robust pool plumbing, whereas the WP700 uses small slip-on hose barbs. A customer would choose the Doheny’s pump for its power, durability, and high-volume capacity in a pool setting. For the delicate, controlled water delivery needed by a tile saw, the Superior Electric WP700 Submersible Water Pump is unequivocally the correct and more appropriate choice.
