To clean a cat water fountain, unplug it, empty it, take it apart according to its manual, clean the removable parts and pump as directed, then rinse and reassemble everything before refilling. The exact method depends on the model: dishwasher-safe parts, pump disassembly, filter care and cleaning intervals are not the same for every fountain.
The safest approach is to treat the fountain, pump and filter as separate components with separate instructions. A step that applies to one model—such as putting certain parts on the top rack of a dishwasher or soaking pump parts in vinegar—may not apply to another. Use the steps below as a sequence, but let the instructions for your exact fountain determine which cleaning methods and replacement intervals to use.

Find the instructions for your exact fountain model before removing parts. Check which components can be washed, whether any are dishwasher-safe, how the pump opens, and whether the filter should be rinsed, discarded or replaced. Do not force a latch or guess how a pump comes apart: designs and reassembly order vary.
Set aside a clean place for the parts and keep the pump, adapter and other electrical components away from the dishwasher unless the manufacturer explicitly says otherwise. If the manual is unavailable, look for the model name on the fountain or its packaging and consult the manufacturer’s instructions before disassembling unfamiliar parts.

It helps to check five details before starting: the order for taking the fountain apart; which removable parts are washable and which are dishwasher-safe; whether the pump can be opened and its impeller removed; the filter type and its handling or replacement interval; and the recommended cleaning schedule. These differences are practical, not merely cosmetic. A cleaning instruction for a particular pump or filter is not automatically transferable to another fountain, even if the parts appear similar.
For example, the PetSafe Viva instructions permit soap-and-water cleaning for specified parts and identify some parts as suitable for the top rack of a dishwasher, while also saying not to put the pump or adapter in the dishwasher. The PetSafe Pagoda guide describes opening the pump to clean its components. Those examples show why the manual for your own model should guide the whole process.

How do you clean a cat water fountain in 7 steps?
- Unplug the fountain. Disconnect it from power before moving or taking it apart. The PetSafe Viva cleaning instructions, for example, say to unplug the unit and disconnect its USB plug. Keep power disconnected throughout cleaning. Do not begin by moving or opening a powered fountain: the power connection should remain out of the way while you empty, separate and wash parts. If a model has a separate adapter or USB connection, follow its instructions for disconnecting that connection too.
- Empty the water. Pour out what remains in the reservoir before washing. This makes the parts easier to handle and prevents old water from mixing with the fresh water you add after cleaning. Emptying is also part of the sequence before disassembly: begin with an unpowered, emptied fountain rather than trying to wash the assembled unit. If you need to move the fountain to a sink or cleaning area, keep the disconnected electrical parts separate from the parts you will wash.
- Disassemble it as the manual directs. Remove the fountain’s removable components—such as its tower, tray or filter housing—only in the prescribed way. Some models have parts that lift off; others use particular latches or an order of removal. Do not force components or assume that another model’s instructions apply. Put the parts aside in a way that helps you keep track of what belongs where, then check the manual if you are unsure which piece comes off next. The goal is to expose the parts the manufacturer says to clean without damaging a latch or pulling on a component that is not intended to come apart. Pump disassembly is a separate question: a removable pump does not necessarily open for internal cleaning, and the method for opening one is model-specific.
- Remove and handle the filter according to its instructions. Some filters are replaced; others may be rinsed as directed. Do not wash a filter with soap unless its manufacturer explicitly instructs you to. Filters and replacement intervals differ by model, so do not substitute one filter type or schedule for another. Check whether the filter in your fountain is meant to be rinsed, discarded or replaced during this cleaning, and follow the instructions for that exact filter. The Viva guidance, for example, warns not to wash its filters with soap and gives different replacement intervals for its Ion-X and foam filters. That does not establish a schedule for a different model’s filter. If replacement is due, use a filter identified as compatible with your fountain rather than assuming that another filter will fit or perform the same role.
- Wash the removable fountain parts. Use the cleaning method specified for those parts. PetSafe says the Viva’s specified parts can be washed with soap and water and identifies certain parts as suitable for top-rack dishwasher cleaning. That permission is model-specific: check your own manual rather than assuming every fountain part is dishwasher-safe. PetSafe also warns against harsh or citrus-scented cleaners for the Viva. Separate the parts the manual identifies as washable from the pump and adapter, and do not extend a dishwasher instruction beyond the components it names. If your model’s guide specifies hand-washing, follow that method rather than treating another model’s dishwasher allowance as permission. Rinse cleaned parts as directed before putting them back together.
- Clean the pump separately. Follow the pump’s model-specific instructions; some pumps can be opened so the impeller and internal surfaces can be cleaned. For the Pagoda ceramic fountain, PetSafe’s pump-cleaning guide describes removing the faceplate, stator and impeller, then washing those parts with mild dish soap and warm water. For mineral buildup, that guide specifies soaking those parts in a 50/50 water-and-white-vinegar solution for at least 15 minutes before scrubbing. Treat this as Pagoda-specific guidance, not a universal recipe; PetSafe says not to use bleach or other harsh chemicals on that model. Do not pry open a pump if its manual does not describe how to do so. The purpose of cleaning the pump separately is to reach the components the model’s instructions identify, not to assume every pump has the same removable pieces. A small pump-cleaning brush can help reach inside compatible pumps; PetSafe describes its Drinkwell Fountain Cleaning Kit as an option with a brush designed for cleaning inside the pump. It is an optional aid, not a requirement for every fountain, and compatibility should be confirmed before use.
- Rinse, reassemble and refill. Rinse cleaned parts as the manual directs and put them back in the prescribed order. Reinstall or replace the filter as instructed. Refill the fountain, and make sure both your hands and the electrical connections are dry before reconnecting power. Check that each part you removed has been returned to its proper place before restoring power; the order of reassembly is model-specific, just like disassembly. Do not reconnect the fountain while your hands or electrical connections are wet. Once it is put back together and refilled according to its instructions, reconnect it as directed for that model.
How often should you clean the fountain?
There is no single schedule that applies to every cat fountain. Follow the interval in your model’s manual, and clean sooner if you see debris or buildup. A household with several pets may need more frequent cleaning than a single-pet household. Dirt and use matter too: Catit advises more frequent deep cleaning of its PIXI Stainless Steel UV-C fountain depending on the number of pets and whether the fountain becomes dirty.

The manufacturer recommendations below illustrate why it is important to check the exact model. They are product-care instructions, not a universal standard:
| Fountain guide | Cleaning recommendation | Filter guidance in the cited guide |
|---|---|---|
| PetSafe Viva | Every 2–4 weeks; more often may be needed in a multi-pet household. | Replace the Ion-X filter every 2–4 weeks and the foam filter every 1–2 months. |
| PetSafe Pagoda | A thorough clean monthly, or about every two weeks for multiple pets or exceptionally slobbery pets. | Use the filter guidance for this model; do not combine it with another fountain’s schedule. |
| Catit PIXI Stainless Steel UV-C | Deep-clean monthly or more often depending on the number of pets and how dirty the fountain becomes. | Follow the model’s own instructions. |
These are not competing universal rules. They are recommendations attached to different fountains and should be used as examples of the variation a manual can contain. PetSafe recommends a 2–4-week cleaning interval for the Viva and a monthly thorough clean for the Pagoda, with about every two weeks suggested for multiple or exceptionally slobbery pets. Catit recommends monthly deep cleaning for the PIXI Stainless Steel UV-C model, or more often depending on use and visible dirt. The interval for your fountain may be different; follow its own guide rather than choosing one of these schedules because it sounds more convenient.
Filter replacement is a separate schedule from cleaning the fountain itself. For the Viva, PetSafe specifies every 2–4 weeks for the Ion-X filter and every 1–2 months for the foam filter. Those intervals should not be applied to the Pagoda, the Catit models or another fountain. A filter’s type matters, and filters should not be treated as interchangeable. If your fountain has more than one filter component, check the instructions for each rather than assuming they are all replaced together.

The manufacturer recommendations come from the guides for the named models: PetSafe Viva, PetSafe Pagoda and Catit PIXI Stainless Steel UV-C. Catit also provides a separate cleaning guide for its Easy Clean Flower Fountain, underscoring that care instructions should be matched to the model rather than generalized across a brand. Check your own manual for the cleaning interval and filter routine, and do not wait for the next scheduled clean if visible debris or buildup appears.
What should you avoid when cleaning a cat fountain?
- Do not clean it while it is plugged in. Disconnect power before moving or disassembling it, and reconnect only when your hands and electrical connections are dry. The cleaning sequence begins with unplugging because the pump and power connections are part of the fountain’s electrical system.
- Do not put the pump or adapter in a dishwasher unless the manual explicitly allows it. PetSafe’s Viva instructions specifically say not to put its pump or adapter in the dishwasher. Its top-rack allowance for specified parts does not include those electrical components.
- Do not assume every removable part is dishwasher-safe. Dishwasher guidance applies only to the parts a manufacturer identifies. A part being removable does not by itself mean it is dishwasher-safe; consult the exact model instructions for each component.
- Do not wash a filter with soap unless directed. PetSafe’s Viva instructions warn against washing its filters with soap; follow the instructions for your own filter. Rinsing, replacing and washing are different options, and the correct one depends on the filter and model.
- Avoid harsh cleaners where the model’s instructions prohibit them. PetSafe cautions against harsh or citrus-scented cleaners for the Viva and bleach or other harsh chemicals for the Pagoda. Use neither vinegar nor any other cleaning solution on a component unless its manual permits that treatment. The Pagoda guide’s 50/50 water-and-white-vinegar soak is specific to its named pump parts and mineral buildup; it is not a general recommendation for all fountains.
- Do not combine filter schedules from different models. The Viva and Pagoda guides specify different routines. Check the fountain’s model and use its compatible filter and schedule. The fact that two fountains share a manufacturer does not make their filter types or care instructions interchangeable.
- Do not guess how to open the pump. Some pumps can be opened for cleaning, but the mechanism and component-removal order vary. Follow the pump instructions for your specific model instead of forcing a faceplate or attempting to remove an impeller based on another fountain’s guide.
How can you tell whether the instructions are model-specific?
Compare the manual’s instructions on five points: how the fountain comes apart; which parts can go in a dishwasher; whether the pump opens and its impeller can be removed; what type of filter it uses and when that filter is replaced; and how often the manufacturer recommends cleaning. A difference in any of these details is a reason to use the instructions for your own fountain rather than adapting another model’s steps.
For example, PetSafe’s Pagoda guide describes removing and cleaning individual pump components, while the Viva guide includes different cautions about its pump, adapter and filters. Catit publishes separate cleaning guides for its Easy Clean Flower Fountain and PIXI Stainless Steel UV-C Fountain. Together these examples show that even within a brand, a model name matters. Use a guide only when it matches the fountain you own; otherwise, use it as a reminder of what to check, not as a substitute for your manual.

When comparing two instructions, look for the exact part names and the actions attached to them. A guide may identify a tower, tray, filter housing, pump faceplate, stator or impeller, but your fountain may not use the same parts. Likewise, a filter described as washable in one set of instructions does not make another filter washable, and an approved cleaning solution for one pump component does not prove that it is suitable for the rest of your fountain. The safest comparison is therefore about the instructions themselves—not about which brand or material is supposedly better.

If you need a brush, treat it as a tool for a task rather than a universal accessory. PetSafe describes a brush in its Drinkwell Fountain Cleaning Kit for cleaning inside compatible pumps. Whether that kit fits or is useful depends on your pump design; it is optional, and the manufacturer’s instructions should still determine what can be opened and cleaned. Similarly, if you need a replacement filter, identify your fountain model and select a compatible filter. Do not purchase or install one based only on a similar shape or a schedule from another model.

How often should I replace a PetSafe Viva filter?
PetSafe’s Viva instructions give separate intervals: every 2–4 weeks for the Ion-X filter and every 1–2 months for the foam filter. Confirm the filter type and current instructions for your fountain rather than applying these intervals to another model.
Can I use vinegar to clean any cat fountain pump?
Do not assume so. PetSafe specifies a 50/50 water-and-white-vinegar soak of at least 15 minutes for mineral buildup on the named Pagoda pump parts; that instruction does not establish that vinegar is suitable for other pumps or fountain materials.

Follow the schedule for your model. PetSafe recommends every 2–4 weeks for the Viva and a thorough monthly clean for the Pagoda, or about every two weeks for multiple or exceptionally slobbery pets. Catit recommends monthly deep cleaning for its PIXI Stainless Steel UV-C model, or more often depending on the number of pets and how dirty it becomes. Clean sooner if you see debris or buildup.
Should I rinse or replace my fountain filter?
Use the instructions for the specific filter. Some filters may be rinsed as directed, while others are replaced; do not wash a filter with soap unless its manufacturer explicitly says to. The Viva’s Ion-X and foam filters have different replacement intervals, so identify the filter type before acting.
The Bottom Line
Unplug and empty the fountain, then follow its manual for disassembly, filter handling, washable parts and pump cleaning. Rinse and reassemble as directed, and reconnect power only when your hands and electrical connections are dry. Use the model’s own cleaning and filter schedule rather than borrowing another fountain’s instructions.
