Great fountain Our cat loves this fountain. So far after 6 weeks no slimy feeling in bowl and it is quiet. Easy to put together and clean. Water is staying fresh.
Good Buy Works great in the cat fountain! Easy to use and doesn't clog the water flow. The price point is good, too. The filters fit as if they were made especially for this fountain. They don't fall apart like some other filters and keep the water fresh and tasty for the furry kids.
quality the water fountain is excellent and the filters are so easy to change
Pet water fountain Love this waterfountain, so do my cats!! ❤️ have had it for over a year n the pump started to go on it, ordered new part, easy to switch out n flowing fast again, like new, happy cats!! Also was able to order package of both filters. Great product
Great cat fountain We purchased 2 of these cat fountains and they both work great. I left a review on the 1st one and I tried to leave another review but it didn't work. So I'm leaving the review here for the fountain. This item here is the pump for it and it is very quiet and works great. Thanks!!!
Purrfect replacement spout Perfect replacement spout for our pet fountain! Even came with a cleaning brush!
Cats evolved to trust running water and to be suspicious of still puddles. A pet water fountain keeps the water circulating all day, which many cats find more attractive — they drink more often, and better hydration supports their overall health. The flowing stream also carries oxygen into the water, so it tastes fresher than a bowl that has sat out since morning.
The DIANU fountain bowl and top are 304 food-grade stainless steel. Steel resists corrosion, does not scratch the way plastic does, and does not hold onto slime or smells, which is why many owners switch from plastic flower fountains. It also takes hot water and the dishwasher. Only the pump, the filter holder and the small spout parts are plastic, and those are washed by hand.
Water passes a release strip, a cotton layer, activated carbon and ion exchange resin, then a pre-filter sponge before it reaches the 5 V pump. The pump runs at up to 180 litres an hour and stays at or below 25 dB, so the fountain is quiet enough for a bedroom or a small apartment. A LED lights the side window, so the water level is easy to check at night.
Replace the filter cartridge and sponge every 1–2 weeks, depending on how many cats drink and how hard your water is. Once a week, take the pump apart and brush the rotor with the cleaning brush. Keep the water between MIN and MAX: a pump that runs dry fails early. Official DIANU filters, a replacement pump and a full accessories kit are sold separately, so one fountain lasts for years.
Yes. It is designed to run 24 hours a day; just keep the water between MIN and MAX so the pump never runs dry.
Lift the stainless top and pour fresh water into the bowl up to MAX. The window on the side shows when it is time.
Every 1–2 weeks. Homes with several cats, hard water or heavy use may need a faster routine.
Usually low water or a rotor clogged with hair. Refill to between MIN and MAX and brush the rotor; if it still won't start, replace the pump.
Yes — it is a pet water fountain for cats and small dogs. A dog empties 3.2 litres faster, so check the window more often.
