ATMZIQXR S18 Stainless Steel Pet Water Fountain, 88 oz / 2.6 L

Product Overview

The ATMZIQXR S18 is a corded pet water fountain designed to provide continuously circulating drinking water for cats and small dogs. It uses a 2.6-liter, or 88-fluid-ounce, reservoir made from 304 stainless steel and includes a transparent window for checking the remaining water level without removing the top assembly.

A submersible 0.8-watt pump moves water through a four-stage filtration system. The filtration media combine activated carbon, ion-exchange resin, non-woven material, and a high-density sponge to capture debris and treat water as it circulates. The fountain supports a raised faucet-style stream and a lower bubbling flow configuration.

The S18 measures approximately 7.8 inches square and 4.3 inches high, with a documented operating noise level of 25 dB or less. Routine upkeep includes washing the stainless steel reservoir, cleaning the pump and impeller, rinsing filtration components, and replacing filters periodically. The fountain requires an electrical connection during use and is intended primarily for indoor pet-watering applications.

• Providing drinking water for small dogs
• Serving households with more than one compatible pet
• Offering a raised flowing stream for pets attracted to running water
• Providing a lower bubbling flow for pets that prefer a gentler water surface
• Reducing the need to refill a small conventional water bowl repeatedly during the day
• Monitoring the approximate remaining water supply through the viewing window

Maintenance & Care

The fountain should be unplugged before cleaning, disassembly, or pump maintenance. Stainless steel components can be washed with warm water and mild pet-safe soap, then rinsed thoroughly so no detergent remains.

The reservoir, lid, and pump should be separated regularly for cleaning. Pump maintenance includes removing the pump cover and cleaning accumulated hair, debris, or mineral deposits from around the impeller. A soft brush can be used for small internal areas.

The filtration media should be rinsed under clean cold water to remove loose debris. Available product documentation recommends replacing the carbon filter approximately every two weeks, with replacement frequency adjusted when contamination, clogging, or water conditions require earlier service.

Internal tubing should also be inspected for slime or buildup. All washed components should be rinsed and allowed to dry before extended storage.

Safety Information

• Disconnect electrical power before cleaning, disassembling, or servicing the fountain.
• Do not operate the pump when the reservoir is below the minimum water level.
• Keep the electrical connection and power components away from standing or spilled water.
• Inspect the power cable periodically and discontinue use if the cable becomes damaged or frayed.
• Fill the reservoir only to the marked maximum level.
• Make sure the pump, filter housing, lid, and water outlet are correctly assembled before operation.
• Rinse cleaning products completely from all food-contact and water-contact surfaces before returning the fountain to service.
• Keep small removable filtration and pump components away from pets during cleaning or disassembly.

Compatibility

The S18 uses replaceable filtration components designed for the ATMZIQXR fountain system. Replacement filters and pump components should be confirmed as compatible with the S18 rather than selected solely by appearance or dimensions.

The fountain is documented for cats and small dogs. Suitability for an individual animal also depends on the pet’s size, drinking position, behavior, and willingness to use moving water.

The appliance requires a wired electrical connection during normal operation. It does not use an internal rechargeable battery for cordless fountain operation.

Frequently Asked Questions

How can I identify the ATMZIQXR S18?

Check the model information on the fountain, packaging, or accompanying documentation. Confirming the S18 designation is especially important when searching for replacement filtration or pump components.

Is the S18 made entirely from stainless steel?

The primary reservoir and documented fountain components use stainless steel, while the operating system also contains non-metal components required for filtration, pumping, tubing, seals, and water-level viewing.

Does the fountain need to be connected to power continuously?

Yes. The pump requires a wired electrical connection while circulating water. This model is not documented as a battery-powered cordless fountain.

Does it require plumbing installation?

No. The fountain uses its own refillable reservoir. It does not connect to household water pipes or require permanent plumbing installation.

How should the fountain be set up before first use?

Rinse the water-contact components, prime the filter in clean water, place the pump in the reservoir, install the filtration system, and fill the tank without exceeding its maximum level. The lid and chosen water outlet are then installed before power is connected.

Can the water level be checked without opening the fountain?

Yes. A transparent window in the reservoir allows the remaining water level to be observed from outside the fountain.

Why has the water flow become weaker?

Reduced flow can result from low water, debris around the pump or impeller, clogged filtration media, or obstruction inside the water tubing. The fountain should be unplugged before these components are inspected.

Why has the pump become louder?

A low reservoir level or accumulated debris can increase pump noise. Restoring the correct water level and cleaning the pump are documented troubleshooting steps.

Can the pump run without water?

The pump should not be operated dry. Maintaining water above the minimum level helps keep the pump submerged and reduces the possibility of damage.

How often should the pump be cleaned?

Available product guidance recommends cleaning it approximately every two weeks. Homes with substantial pet hair, mineral-heavy water, or visible debris may require more frequent attention.

How is the impeller cleaned?

After disconnecting power, the pump housing can be opened to expose the impeller area. Hair and deposits can then be removed carefully with a small soft brush.

What can cause an unpleasant taste or odor in the water?

A saturated filter, dirty reservoir, contaminated pump, or overdue cleaning can affect water condition. Cleaning the fountain and replacing exhausted filtration media are standard maintenance responses.

Can mineral deposits form inside the fountain?

Yes. Minerals present in household water can accumulate around pumps and water-contact surfaces over time. Periodic cleaning helps control deposits and maintain circulation.

Can this fountain be used for dogs?

Product documentation identifies small dogs as a supported pet category. Larger dogs may require a fountain with a different drinking height, bowl area, or reservoir capacity.

Does the S18 have different water-flow options?

Yes. Its documented configurations include a faucet-style stream and a bubbling flow, allowing the drinking surface to be changed for different pet preferences.

Does the fountain have a water-level sensor or automatic shutoff?

A transparent level window is documented, but reliable public information reviewed for this page does not establish an automatic low-water shutoff feature. The reservoir should therefore be checked regularly.

Can generic filters be used?

Filter compatibility should be confirmed before use. Size, shape, filtration layers, and installation method can differ among fountains even when replacement filters appear similar.

What should be done before storing the fountain?

The unit should be unplugged, emptied, cleaned, rinsed, and completely dried. Filters that are no longer suitable for reuse should be discarded rather than stored wet inside the fountain.

Buying Considerations

The S18 requires access to an electrical connection, so placement is more restricted than with a battery-powered fountain. Cable routing should also prevent pets from pulling, chewing, or becoming entangled with the power lead.

Filter replacement is an ongoing maintenance requirement rather than a one-time setup task. Pump cleaning is equally important because accumulated hair and mineral deposits can reduce water flow and increase operating noise.

The 2.6-liter reservoir offers more stored water than a small drinking bowl, but actual refill frequency depends on the number and size of pets, evaporation, ambient conditions, and individual water consumption.

Stainless steel simplifies cleaning of the main water-contact surfaces, but the pump, filter housing, tubing, and other internal areas still require periodic disassembly. These maintenance requirements should be considered when comparing fountain designs.

Customer Feedback Summary

This section is a generalized summary of recurring themes in publicly available customer feedback. These observations describe individual user experiences and are not verified product specifications.

Positive feedback commonly focuses on quiet operation, straightforward assembly, stainless steel construction, and the ability to see the remaining water through the reservoir window. Users also frequently mention the fountain’s capacity and circulating stream as useful aspects of everyday pet watering.

Ease of cleaning receives generally favorable comments, particularly for the accessible stainless steel reservoir. Some users also report that their cats adapted quickly to the flowing water, while others note that individual animals may require an adjustment period or may continue to prefer a conventional bowl.

Recurring limitations center on routine filter replacement and pump maintenance. Hair, mineral deposits, and debris can affect flow if the pump is not cleaned regularly. Some users also find disassembling the pump and filtration components less convenient than washing a simple stationary water bowl.
