Petmate Fresh Flow Pet Fountain 108 Oz – Full Review

Petmate Fresh Flow Pet Fountain 108 Oz.

Petmate Fresh Flow Pet Fountain 108 Oz.


Petmate Fresh Flow Pet Fountain is a quiet purifying fountain that encourages your cat to drink more water as pets love fresh flowing water.

Special charcoal filters purify the water and a silent-operating submersible pump helps to supply cool and oxygenated water.

The unit includes a transparent 108 Oz reservoir that automatically adds water to the drinking bowl as the water level gets low. Additionally, the unit comes with 120-day supply of charcoal filters that help to remove impurities and odors.

A unique design with angled ramp prevents water from splashing and getting to your floor and special rubber feet to keep the fountain from sliding.

The Petmate Fresh Flow fountain comes in three colors: bleached linen, black and white. And there are three sizes:

  • 50 Oz water capacity with dimensions of 10.9”x 9.25”x 5.2”
  • 108 Oz capacity, dimensions 14.1″ x 10.1″ x 7.7″
  • 216 Oz. capacity 17.4″ x 14.4″ x 8″

This particular review is for the 108 Oz. capacity version.

  • Plug the unit to make it operate. You might hear a humming noise when you do this; it is the pump getting started so don’t worry, it is part of the process. When done, you should see a little stream of water falling. It might take from 2 to 3 minutes before the fountain starts showing the running water on the water-slide.
  • The induction to this fountain to your pet has to be done as a process. To make your cat used to this, you should put the unit close to the regular water bowl. Once your cat gets familiar with this new fountain and starts using it, you can take the regular bowl away.
  • To refill it, you do the same process of detaching the back reservoir and filling it with water, fill the bowl reservoir with water as well. Never leave the water level too low or the machine will start making loud gurgling noises.
  • After a week of use, it is a good idea to check the filter to make sure is not full of hair, if it is, just wash it and put it back. The filter should last up to 60 days, but this will depend on how many pets are using the fountain.
  • You have to clean the fountain deeply (including the pump) at least every other week to keep the unit working properly and ensuring the functionality of the pump. To clean the Petmate Fresh Flow you have to disassemble the unit and wash the parts by hand with mild dish soap. The parts are not dishwasher safe.

These are general instructions for basic information only. More detailed information in the owner’s manual.

  • If you want to keep the unit clean longer, you can add silver sol water to the reservoir: this helps to maintain the water clean, pure and the silver is also good for cat’s immune system.
  • You have to change filters after several weeks or when: the water flow slows down, your cat stops drinking water or debris block the filter screen.
  • To help the filter to last longer you can use filtered water.
  • If you have hard water it is a good idea to clean the parts with vinegar and soda to remove hard water accumulation.


Note: The Petmate Fresh Flow’s reservoir does not discharge water continuously, only when the bowl drops to a certain level.



  • The Pemate Fresh Flow pet fountain does what it’s supposed to do: give your cat a moving source of water which encourages your pet to drink more.
  • The unit has mainly two downfalls though: it is not a breeze to clean it and the pump gets clogged periodically. So you have to do an often maintenance (as any automatic water fountain) if you want to ensure its operation.
  • As the filters don’t seem to filter the water properly, it is a good idea to use this fountain with filtered water. If you use filtered water and keep the unit clean often, you will enjoy a good product that will make your cat to drink more water.
  • The 108 Oz capacity is a little small for several pets (more than 2).

For the reasons mentioned above and the pros and cons of this fountain:


? I recommend the PetMate Fresh Flow Pet Fountain 108 Oz if you fit all these criteria:

  • You will use the unit for one or two cats maximum
  • If you are tired of your pet drinking water from the faucets or the toilet.
  • If you use the unit with filtered water (to make your life easier)
  • If you are willing to do a periodical maintenance to the fountain (such as not to leave the water go low and clean it at least twice a month)
  • If you don’t mind humming noise of the motor (it is pretty quiet when filled with water and clean)


x I don’t recommend the Petmate Fresh Flow 108 Oz:

  • If you want to use it for more than 2 pets.
  • If you don’t want to buy filters or neither to use filtered water.
  • If you don’t want to do maintenance to the fountain
  • If you want a very silent unit.
  • Cats with allergy to plastic
