Hey everyone! I've got this old American Standard toilet from 2006, and the fill valve finally gave up on me. I'd prefer to just swap out the fill valve instead of getting a new toilet. The twist is that my toilet doesn't have a standard overflow tube; instead, there's a built-in overflow in the toilet fixture itself where the tube used to be attached. I found a diagram online that shows the mechanics, and I'm wondering if there are any aftermarket fill valves that can work without that overflow tube. Also, could a downspout be a solution for filling the cistern? Any thoughts? I linked to a video where you can see the overflow at around 02:30 for more context.

Looks like there’s a hose going to a port near your flush handle in the video. Does your setup have a similar port? If you're able to connect a hose there, that could work for your situation!
You might want to check out this link for some replacement options, but I get it, $137 is steep for just a fill valve! There are definitely cheaper alternatives out there; just keep an eye on compatibility with your setup. Good luck!
Haha, right? I could just buy a whole new toilet for that price!
I’d suggest replacing both your flush valve and the water supply tube while you’re at it. Korky has some nice kits that work well without that overflow setup. Just make sure to check the size of the drain hole for the flapper before you buy anything!
Just a heads up—those kits might not fit one-piece toilets, so double-check what you have!
2006 toilet feels ancient? Yikes! I feel for you, buddy. Honestly, if it’s been a hassle, you might just want to consider getting a new one anyway!
Yeah, it’s definitely been a pain. I was hoping a fill valve change would be a quick fix, but I might just bite the bullet and look for something new.

Yeah, it does! I’ve got a broken tube there that should refill the cistern. Just need to figure out how to reconnect it.
