Is There Such Thing as Good Check Valves?

[AquaticQueen]

I've been looking into getting a sponge filter for something but I can't seem to find any check valves that actually sound reliable and that aren't way out of my price range. All of the ones I've looked at had a bunch of reviews complaining about leaks, malfunctions, etc. Does anyone know of some check valves that aren't going to leak right away that I can get for a reasonable price? Thanks.

Since it has never happened to me I didn't know there was a problem with check valves leaking. I just have very inexpensive check valves and maybe I've just been lucky but I've never had one fail.

These are the ones I am using right now and are the only kind I have ever used.

I've never had one leak. And they are cheap. I just buy what's for sale at the store or whatever comes with the pump if it's supplied. I'm curious about expensive ones. The valves mattgirl linked to cost pennys each.

Thanks for the responses, guys! I think I'll just buy the best ones I can find and hope for the best. I looked around a bit and it sounds like I won't be able to find a really good valve. I think I'm setting my expectations too high haha.

It’s a vacuum check valve. Why limit yourself to aquaria? Aviation or automotive ones need to meet standards.

I have a bunch of the ones from Aquarium Coop, and several different types from Amazon and Pet Supplies Plus. I probably have about 60 check valves in use at any given time, and have never seen a leak. When the valve is new, before I attach it, I blow air into it from both ends. I want the air to travel through in the proper direction without an excess of resistance. And I want no air at all to get through from the tank end. I've only thrown out 2 that could not resist me blowing in the tank end, I figured they would leak.
