Review: Great product!!! - I am not a handy person but I was able to remove my broken Fill Valve and replace with this one. It's been a few months now and I've had no problems. It was somewhat easy to put together. I will admit I had to watch a video on YouTube because I got a little confused with the instruction. My water bill is lower due to the Fill Valve not leaking and wasting water. I can also sleep better at night not having to hear the broken Fill Value "running". I give this product a thumbs up and will definitely recommend to friends and family. I will also purchase again if needed.
Review: Fixed Water Hammer Issue - This valve resolved my toilet water hammer issue. My water pressure is 60 PSI. First tried partially closing the toilet fill line valve, but this resulted in water noise from the valve. Next tried a water hammer arrestor on the fill line, but it was not effective. Then tried this fill valve, and it resolved my toilet water hammer issue. We still have a little water hammer, but it is reduced to what we consider an acceptable level. It took me around 15 minutes to install.
