PetSafe Healthy Pet Water Station- Medium, 1 gal Capacity- Gravity Cat & Dog Waterer- Removable Stainless Steel Bowl Resists Corrosion & Stands Up to Frequent Use- Easy to Fill- Filter Compatible

I purchased the PetSafe Heathly Pet small after trying the pump fountain type units. These are often a pain to clean, collect hair, need replacement pumps and filters. This water station is something different and it is fantastic - no complicated parts, all dishwasher safe, no filter to clean, quality construction (parts feel thick and strong) PetSafe Healthy Pet Water Station, Small Best features: - Dishwasher safe - No filters to buy - Looks nice Pros: - If you've had similar items you know what I mean when I say being able to throw everything in the dishwasher is a big plus. Never worry about bacteria and associated issues, I just put mine in once a week, which is about how long the water lasts. - No filters to buy is a pro to me. Some people want the extra assurance these small filters offer, and they make filters for these. But they are not required and the unit works great without them. Instead of filters, see the weekly dishwasher comment above. PetSafe Healthy Pet Water Filter, 2-Pack, PFD17-11867 - Asthetics. Last in my list, but still a consideration if this is in the kitchen. It looks nice, stainless steel and black, not too obtrusive. Cons: - No real cons. The black lid serves no purpose other than aesthetics, yet it is removable for some reason. Opinion: Buy one if you need a pet water fountain / station. Small is good for one cat, medium for 2 cats or a dog, and the large is big so plan to put it somewhere out of the way. Filters are the same for all sizes. I've used many types, and this is easy to clean, only a plain old bowl would be easier. No moving parts or anything to break.

Dogs love it! Easy to fill and clean. Always plenty of fresh water for them.

I got 2, one of the broke, the spiral thing went missing to one of them so it's a bit inconvenient to refill but it still works, we had ours for a few months now and it held up pretty well, it's plastic and I could not find if they sell replacements other then the filters(witch I did not try), a replacement bowl and the spiral metal thing

Fantastic for my dogs. Great item.

This is a great bowl but mine arrived without any instructions other than an advertisement for the filters and how to install them. Initially I thought it was missing parts like the bowl and a cap that I describe later. I hope this review saves others time and frustration in case yours does not have instructions like mine. The box contains the reservoir on the top and in a false bottom I later discovered, the bowls. I almost returned mine because I thought parts were missing! The top of the reservoir contains a black plastic ring that covers the molded portion of the reservoir itself. Both pieces function as a handle to carry the filled or empty jug and as a way to lock the reservoir in place to the bowl after you refill the bottle. It also allows the top part to lay flat on the floor for refilling or screwing on the filling cap. ASSEMBLY: I have included photos of what the bottom screw on lid looked like on arrival. Note the center bottom hole is open. 1) If you do NOT plan to use the optional charcoal filters, there is a cap sitting on a post that you MUST use to cover this center hole or your reservoir will overfill. I suspect this is the reason some complain of overfilling. As there were no directions, I missed this little cap at first. See the pictures that I provided. This cap sits in a post on the fill cap that is easy to miss. 2) IF you plan to use the filters, these come with black valve that fits into the hole so you MUST put the cap on its post to have it work properly. The filter will not work unless you take this cap off so water can flow through the filter mechanism. FILLING: You cannot fill this from the top as some reviews suggested. It fills from the bottom but it has a cap that screws on the bottom to prevent spilling and leaking while you are carrying or installing the reservoir to the bowl. Water comes out of that spring loaded valve once the reservoir is locked in place. I am older but had no issues carrying the filled reservoir. Even filled, the container was not too heavy. BOWL DEPTH: Some reviews stated their bowls were not sufficiently deep. We have two larger dogs including a 105 lb German Shepherd and at least for the large size we ordered it works for either dog. The bowl is about 3-4 inches deep on the front where they drink so that is more than sufficient for most dogs. WATER FLOW/NOISE: I noticed very little noise while the water flows into the dish. You hear a faint glug but it should not wake one up or be bothersome for most. It does fill somewhat slowly when first filling the bowl from empty but my dogs had no issue getting the water they needed while drinking. Having too small a dish for your dog may cause issues I suppose. Those who report loud glugging sounds may want to check that their center hole cap is secured (if not using a filter). I have not used a filter yet so I cannot comment on sounds it may make with that installed. Sorry for the long review but I hope it solves some issues that others reported and helps those trying to figure it out if there are no instructions in the box like mine.
