If you're already noticing issues, might be worth checking behind the scenes sooner rather than later...
Yeah, that's a good point. Sometimes it's easy to assume it's just a small issue like the valve, but internal corrosion can really sneak up on you. Did you notice any discoloration in the water beforehand, or was it just the slow refill?
"internal corrosion can really sneak up on you."
Yeah, corrosion is definitely one of those sneaky issues you don't think about until it's too late. I had a similar experience last year—thought it was just the fill valve acting up, but when I took the tank lid off, there was some pretty nasty rust buildup inside. I'd noticed the water was refilling slower than usual but hadn't really paid attention until it turned into a bigger headache. Thankfully caught it before things got worse.
Have you tried looking inside your tank yet? Sometimes corrosion or mineral deposits can start small and aren't obvious until you do a closer inspection. Also, do you have hard water in your area? I've found that makes things deteriorate faster than you'd expect...
Are you sure it's corrosion causing the slow refill? I had a similar issue, thought it was rust too, but turned out the fill valve was just clogged with sediment. Might wanna double-check before assuming it's corrosion and spending extra money replacing parts...
"Are you sure it's corrosion causing the slow refill? I had a similar issue, thought it was rust too, but turned out the fill valve was just clogged with sediment."
Good point about sediment buildup, but I'd caution against dismissing corrosion entirely. Sediment usually causes intermittent flow or sputtering, whereas corrosion tends to steadily restrict water flow over time. I've seen plenty of cases where rust inside older galvanized pipes gradually narrows the passageway, causing consistently slow refills. Checking the fill valve is smart, but if it's clear, don't overlook the possibility of internal pipe corrosion—especially in older plumbing setups.
Good call on checking sediment first—I spent a whole weekend convinced my pipes were rusted out, only to find a chunk of mystery gunk blocking the valve. Felt pretty silly afterward, lol. Still, corrosion can sneak up on you, especially in older houses. If clearing the valve doesn't do the trick, might be worth peeking at the pipes themselves... plumbing adventures never end, do they? Hang in there, you're not alone in toilet drama land.
