 Toilet fill valve making continuous hissing sound
Author: theyegis (NJ)

Hi all. First time poster here so apologies for any mistakes. My fill valve has recently started to make a pretty steady hissing sound, even when not flushing. Here's the link to two videos to demonstrate this: [photos.app.goo.gl]

In the shorter one, you can even see a little water movement where the grey cylinder meets the black. Anyone know what could be wrong?

you have a very common problem with a very popular fill valve.
have a look at a few google videos and decide if it is something you want to attempt yourself.
it really is a simple fix.

probably debris stuck in the hole under the washer.
make sure you shut off the water first....
it really is a simple as this video makes it look.
the washer is in the top that you remove and there may be debris in the hole that is in the shaft.

if the washer has a knick in it, just replace it. it pops right out.

Thanks again. You had an Amazon link in your post earlier that it seems you removed. Wanted to double check this would be the part to replace: [www.amazon.com]
