Many people are complaining this drinker overflows and leaves their birds without water, but there’s a simple fix to this problem. This drinker is a good product, but there’s a trick to keeping it from leaking everywhere. I sent my first one back, the second ended up in the shed on a shelf. But now I use it every day and love it.
First of all, I’m sure you already know it’s important to place the drinker on level ground, and up on a cinder block is good practice too. But here’s the real trick to stop it from overflowing. After you fill the drinker full, loosely tighten the cover on top. Remove the black cap on the side allowing the fountain to fill. While it’s filling, loosen the black cover on top (kind of a lot) then tighten it again. This will create the vacuum needed to stop it from overflowing. That’s it!
