I’ve had mixed luck with silicone washers, honestly. They’re great at first, but in a couple of my rentals, they started leaking after a year or two—maybe the water quality? I still lean toward rubber for most fixes. Metal’s solid, but yeah, overtightening is a real risk... seen tenants do it more than once.
Yeah, I hear you on the silicone washers. They seem perfect at first, but I’ve had a couple go soft and start leaking too—especially in places with hard water. Rubber’s not perfect either, but it’s usually less hassle. Metal’s great if you trust everyone to not crank it down... which, let’s be real, rarely happens.
I’ve run into the same thing with silicone washers, especially in older buildings where the water’s got a lot of minerals. It’s weird—they look fine for a while, then suddenly you’re dealing with a slow drip or, worse, a little spray that sneaks out and soaks the cabinet. Ever notice how they almost melt if there’s any cleaning chemical residue? I started double-checking what cleaners folks use around the fixtures after seeing that.
Rubber’s been my fallback too, but it’s not foolproof. I’ve seen them get brittle and crack if someone overtightens or if the water gets too hot. Metal washers are solid, but like you said... most people don’t know their own strength when they’re tightening things down. I had one job where someone used pliers on every fitting—ended up with stripped threads and a warped valve body. Not fun.
Do you ever use those fiber washers? I’ve tried them in low-pressure spots, but I’m never sure how long they’ll last. And with these toilet sprayers, I always wonder if it’s better to swap out the whole hose assembly every couple years instead of just chasing leaks at the joints. Feels like overkill sometimes, but I’d rather avoid a surprise flood.
Curious if anyone’s found a washer material that actually holds up in hard water over time. Or is it just about regular checks and not trusting anything to last forever?

Honestly, I haven’t found a “forever” washer yet, especially with hard water in the mix. I get what you mean about silicone—on paper it sounds perfect, but in practice, mineral-heavy water and stray cleaning chemicals seem to eat through them faster than you’d expect. I’ve seen them go soft and gummy, almost like they’re dissolving, even when everything else looks fine.
Rubber’s hit or miss for me too. It’s cheap and easy to replace, but like you said, overtightening or hot water can turn it into brittle confetti. Metal washers are tough, but they don’t seal as well unless everything’s perfectly flat—and let’s be real, most of these old fixtures are a little warped already.
Fiber washers... I’ll use them for things like garden hose connections or low-pressure stuff, but I don’t trust them anywhere that could cause real damage if they fail. They swell up and seal okay at first, but once they dry out or get hit with a bit of heat, they shrink and start leaking again. Not worth the gamble under a sink or behind a toilet.
On the toilet sprayer hoses—yeah, I’ve started swapping the whole assembly every few years rather than chasing leaks at every joint. It does feel like overkill sometimes, but after one too many surprise puddles under the cabinet (and one ruined roll of TP), I’d rather just replace the whole thing before it becomes an emergency. The cost isn’t that bad compared to the hassle of cleaning up water damage.
At this point, I think regular checks are just part of the deal. Maybe there’s some magic polymer washer out there that lasts forever in hard water, but if there is, I haven’t found it yet. Until then, I keep a pack of assorted washers on hand and check for drips whenever I’m under the sink for something else. Not glamorous, but it beats getting surprised by a leak at 2am.

Yeah, that’s been my experience too. I’ve tried “premium” washers and they still end up mushy or cracked after a year or two. Honestly, I think the only thing that lasts forever is the need to crawl under the sink every so often and curse at the plumbing. Anyone else ever find a washer that actually outlived the fixture? Because I sure haven’t.
