I get where you’re coming from, but I’ve seen plenty of old buildings where low-flow toilets work just fine—sometimes better than the old ones that guzzle water. The trick is regular maintenance. If you’re dealing with decades of buildup, yeah, you’ll have issues no matter what toilet you install. But once the lines are clear, low-flows can actually help prevent future clogs since they don’t overload the pipes. Not saying they’re perfect, but I wouldn’t write them off just because the plumbing’s old. Sometimes it’s just about keeping things moving, literally.
I hear you, but I’ve seen low-flows struggle in some older spots, especially where the main lines are narrow or have weird bends. Ever had to deal with a place where even after clearing the pipes, clogs kept coming back? Just curious if that’s more about the building or the toilet design.
Had a rental once where the pipes were ancient—think 1940s, lots of weird twists and turns. We put in a low-flow to save water, but honestly, it was a constant battle with clogs. Plumber said the toilet was fine, but those old, narrow lines just couldn’t handle it. Ended up switching back to a regular flush. Sometimes it’s just the building, not the toilet. Newer plumbing seems way more forgiving.
