I get where you’re coming from—early low-flows were kind of a gamble. If anyone’s still dealing with double-flushing, here’s what I usually suggest:
1. Check the flapper and chain first. Sometimes it’s just not opening all the way, which kills the flush.
2. Make sure the rim holes aren’t clogged up with mineral deposits. That can slow things down more than you’d think.
3. If those are fine and it’s still weak, upgrading to a newer model like the Drake is a solid move. Some brands have really figured out how to make 1.28 GPF work without sacrificing power.
Honestly, it’s not always about pressure-assist—gravity models can do the trick if they’re designed right. Just gotta pick carefully and maybe avoid those bargain-bin options... learned that one the hard way.
Had a job last month where the customer swore their “eco toilet” was just junk, but it turned out the chain was so short the flapper barely lifted. Fixed that and it flushed like new. I’m with you—sometimes it’s not the toilet, it’s just a little thing messing things up. Still, I’ve seen some cheap models that just never work right no matter what you do... makes me wonder if saving a few bucks is ever worth it. Anyone else notice some brands just seem to get it while others are always trouble?
Honestly, I think a lot of the “eco toilet” hate comes from little install quirks like that. But I’ve had a low-flow for years and it’s been solid—no double flushes, no drama. Maybe it’s more about the install and less about the brand? Some of the cheaper ones do feel flimsy, though... I get that. But I’d rather tweak a chain than waste gallons every flush.
Maybe it’s more about the install and less about the brand?
That’s spot on. I’ve seen plenty of “bad” low-flows that just needed a quick adjustment or a better wax ring. The install makes a huge difference—if the tank lever or chain isn’t set right, you’ll get weak flushes or have to double up. I do agree some budget models feel pretty flimsy, but even then, a careful install can help them work better than folks expect. I’d take a little extra setup over wasting water every time, too.
I get what you’re saying about install making a difference, but I’m not totally convinced it’s the whole story. I’ve had two low-flow toilets in different houses—one was a pricier brand, the other was a budget pick. Both were installed by pros, but the cheaper one just never worked as well, even after a couple tweaks. It’s not just about the lever or wax ring either... sometimes the bowl design or trapway is just too narrow and you end up plunging more than you’d like.
I’m all for saving water, but if you have to flush twice half the time, is it really helping? Maybe I just had bad luck, but I do wonder if spending a bit more upfront on a better model saves headaches down the line. Anyone else find that some of the super cheap ones just don’t cut it, no matter how careful the install?
