Easy Install / Perfect Function

 Would Recommend

My toilet was taking a very long time to refill. I purchased this fill valve and was able to do the replacement myself in about an hour or so. Toilet fills like it's supposed to now! I can only imagine that a plumber would've charged me at least $200 for the job. This part was like $11.
