Why this product
The Drinkwell Original is the pet fountain you buy first if you have never owned one. It is $49, it works, and PetSafe has been making essentially the same design for over a decade. That track record is the actual reason to consider it, the engineering risk on a long-running product is much lower than on a brand new one.
The fountain holds 50 oz (1.5 L) of water, enough for typical 1 to 2 day refills for a single dog or a multi-cat household. The signature feature is the free-falling stream, water is pumped from the reservoir to the top, then falls down a ramp into the bowl. PetSafe’s marketing positions the moving water as encouraging hydration and adding oxygen to the water, which is the consumer-fountain pitch most brands use.
The carbon filter sits at the inlet, removing chlorine taste and trapping debris. PetSafe sells replacement filters in multi-packs that bring the ongoing cost down to a few dollars per month per fountain.

What PetSafe claims
PetSafe claims a 50 oz (1.5 L) capacity. This is the actual reservoir volume and matches the published spec.
PetSafe claims a free-falling stream that aerates the water and encourages drinking. The aeration claim is real, water exposed to air picks up dissolved oxygen, though the practical impact on a pet’s hydration is anecdotal.
PetSafe claims a replaceable activated carbon filter with a 2 to 4 week service life. Real-world filter life depends on water hardness, dust, and pet hair entering the system. In hard-water areas, filters clog faster and need more frequent replacement.
PetSafe claims dishwasher-safe parts (top reservoir, bowl, ramp). The pump must be hand washed, and PetSafe recommends a full pump disassembly and cleaning every 2 to 4 weeks to prevent biofilm buildup.
PetSafe claims a low-voltage submersible pump. The fountain runs continuously off a wired AC adapter at low wattage. Owner reviews on Amazon report typical electricity cost as effectively negligible.
PetSafe claims BPA-free plastic construction throughout. The body is a single piece of opaque plastic with the bowl and ramp molded as separate parts.
Who should buy the Drinkwell Original
Buy this if you have a single dog or one to two cats and want a working fountain for $49. The capacity matches the household and the price is right.
Buy this if you have a pet that ignores still water in a bowl. The free-falling stream is the feature most likely to actually get a reluctant drinker to engage with the fountain.
Buy this if you want the cheapest Drinkwell with PetSafe’s track record. The brand has been making this fountain for years and the parts are widely supported.
Skip this if you have a large dog. The 50 oz capacity will need refilling more than once a day. The Multi-Tier at 100 oz is the better fit.
Skip this if pump noise is a concern. The Original’s pump is audible at close range in a quiet room, the Multi-Tier model is quieter.
Skip this if you have very small pets exclusively. The Drinkwell Mini at $35 is the right size for a single small cat or small dog.
Stream design and water freshness
The free-falling stream is the actual feature that distinguishes a fountain from a bowl. Water moves continuously from the reservoir up to the top spout, then falls down a single ramp into the bowl. The motion adds dissolved oxygen and keeps the water from sitting stagnant.
For dogs and cats who shy away from still water, the visual and auditory cue of moving water is genuinely useful. Owner reviews consistently flag this as the reason a previously reluctant pet started drinking more.
Cleaning and filter maintenance
The dishwasher-safe parts (top reservoir, bowl, ramp) make weekly cleaning straightforward. The pump itself requires hand washing and PetSafe recommends a full disassembly clean every 2 to 4 weeks. Skipping this maintenance is the most common cause of pump noise increase or fountain failure, biofilm builds up on the impeller and degrades flow.
Filter replacement is the ongoing cost. PetSafe rates each carbon filter at 2 to 4 weeks. In a typical household with municipal water, the longer end of that range is realistic. In hard-water or high-dust environments, the shorter end is more accurate.
Pump noise and power
The pump is the noisiest component, audible at close range as a low hum. Most owners describe it as similar to a small aquarium pump. In a kitchen or laundry room, it blends into ambient noise. In a quiet bedroom, it would be more noticeable.
Power draw is low. The fountain runs continuously off a wired AC adapter, with electricity cost effectively negligible per month. The wired design means you cannot place the fountain far from an outlet, which is the typical constraint for any plug-in pet fountain.

Should you buy the PetSafe Drinkwell Original Pet Fountain?
The PetSafe Drinkwell Original is the cheap pet fountain that has been around long enough to prove itself. PetSafe lists a 50 oz capacity, a free-falling stream that adds oxygen to the water, and a replaceable carbon filter. The pump is louder than the newer Multi-Tier model, and the design is more dated, but for $49 the value is hard to argue with.
