Motor: The motor is noisy and after 3 weeks is considerably less powerful than when we first got it with water reduced to a trickle. I do not think this motor will stand the test of time which is dissapointing because a low level fish filter motor can pump out a lot more water and run for years.
Filter: My issue isn't so much the carbon filters as those work well. The issue is the bio foam filter. Bio-foam holds bacteria and is commonly used in fish filters to be a breeding ground of good bacteria for the fish tank. This bio foam is the first stage of the filter and for drinking water I find it useless. The instructions say it is for filtering out particles before the pump however that is what the screen doors are for. The plastic screen doors that are there to filter hair should be made of a mesh instead of a case to filter out anything replacing the bio-foam. I do not know why they did this. The bio-foam seems like it could be a breeding ground for bad bacteria making your bowl dirtier and potentially harm your pets. If someone with more knowledge on biology wants to chime in and let me know why they put this in the product for pet drinking water that would be awesome.
Update: the motor is pretty much dead. I took a video of it and the thing didn’t even make it three weeks.
Update #2: Alright the pump is not bad or weak but a crucial engineering flaw makes it weak. There is one exit point on the motor where the housing sits for the filter and water to flow through. This housing connects to the pump which allows the water to flow through. Whatever brilliant engineer designed this needs to be taken outback and beaten or at least have their engineering degree revoked. They placed a water circulatory diverted on this so this small pump pushes water through a 3/8th inch hole. The water circulatory tubing is 3/8 inch thick and the hole for the water to flow up into the filtration system is about 1/4 inch this maybe smaller. The water is going to take the path of least resistance and this small pump does not pump enough water to push it through two different paths. I mean it is common sense. When the water circulatory tubing is plugged up the water flows great. Further when you drill a 3/8 inch hole into the filtration system this thing really pushes water and circulates it enough that there is no need for a circulatory tubing. So plug the white tube with silicone tank grade caulk and you now have a five start product.
Update#2: The pump has been working fine with the adaptions I made for it however it is so tough to keep clean with the filter and scum. After about 5 days the water smells so terrible that my dog would rather go to the toilet bowl to drink out of it. He is part newfy so when he drinks he tends to dip his whole face in the bowl. The pet fountain we have downstairs needs cleaning about once a month though so I am unsure the reason. The pump filter needs to be taken apart every cleaning which is a pain and needs cleaned every week. The original screens were junk and the mesh screens I had adapted still do not keep a lot of the hair and food particles from clogging the screens on the pump. Overall the design leaves a lot of be desired and I think if they had a pre-pump filter the entire contraption would stay a lot cleaner. I scrapped the pump and the fountain and am just using this like an old dog watering bowl now. Great idea but they need a re-design
