We've got a toilet that suddenly won't fill.  Flushes fine when filled but then the incoming water barely trickles from the fill tube.  If I turn off the water supply valve and then back on it fills fine.  Any ideas?

Thanks

Toilet parts are cheap. I'd guess the filler valve is sticking closed. Reintroducing pressure by opening the service valve might jar the filler valve open. I'd start by replacing the filler valve.

replace the filler valve as already stated.

you could try and clean it but it's almost always a waste of time.

+1. I've tried to no avail. Same with the float valves in water treatment systems. When they go, the go.

So I bought a new fill valve and got it installed - it is dripping from/the top cap.  Other than that it seems to work OK.  I have no idea why that is occurring

Clean ours with vinegar a couple times a year, due to the mineral buildup.

With the fill vale float down, pour vinegar on the float and get some to run down the fill valve stem. Let it soak and do it once more.
Then twist and pull the float up and down for a bit, working the buildup off the stem.
About 10 minutes of your time will save buying another fill valve.
I do keep an extra fill valve as both commodes use the same one.

This is  brand new fill valve

It sounds like the new valve is defective. You should remove it and return it for a replacement.

Check your home’s water pressure.  I’ll bet it’s too high , causing the new valve to leak.  

Is it a korky by any chance ?
