how do I know which part is leaking?

The toilet runs constantly and the old flapper is partially disintegrated, I guess from the chlorine. But how do I know if its the valve or the flapper that is leaking?
Asked by: handymom24
Turn off the water supply. If it is the valve, your leak will stop. If all the water drains out, it is the flapper. However, it is best, in my opinion to just replace both. Save yourself the worry and hassles. There are kits that contain both parts and are cheaper than trying one piece then the other.

Fill Valve and Flapper Repair Kit is rated 4.5 out of 5 by 225.
Rated 5 out of 5 by from Easy to install, Worked well the first time This things looks intimidating at first to install. But if you go to YouTube, there are a lot of DIY videos that show you how to do install it properly without getting water all over your bathroom, or breaking anything. I've done this twice already in 6 years. It's a really easy installation. And for the price, this is the best deal. Even though everything is plastic, the build quality of the parts and assembly are pretty high. I'm very satisfied with this purchase.

Rated 4 out of 5 by from Replaced Glacier Bay toilet fill valve Had to replace works because Glacier Bay 1.6 gpf toilet was constantly running. Easy to install following the directions. After completing installation, toilet still had slow leak identified by slight sound of toilet running. Called manufacturer 800 # listed on instructions. They told me to follow the flushing out procedure listed at end of instruction sheet. This worked.

Rated 1 out of 5 by from Bad luck with product When I purchased this item feeling I was sure it would fit my need from past experience with the product and having purchased the same one twice at some time in the past. When I attempted to use it I found it was defective and could not adjust the tank water level as it is supposed to do as the inner pipe which should was completely stuck. I was going to return it and looked for the receipt from the self check out I had received and found that sale item had been charged to my credit card for a total of only $0.01. Unable to understand this I took my receipt to an employee at the store and showed her the receipt and was told that that line had been discontinued and could not explain how the one I had taken was even on the shelf . It was suggested I just take advantage of my good fortune and accept it. When I got home and after trying unsuccessfully to make it work decided that as I had basically been given the thing to just junk it. I was able to get the old control working well enough for the time being and eventually will endeavor to find a suitable replacement to complete the job.

Rated 5 out of 5 by from Fill valve and flapper repair kit Bought two of these kits to replace toilet tank valve and flapper for both house toilets due to minor running water on one unit. Just follow the six easy steps and you can’t go wrong trust me. Word of advice pay close attention to the second step which is to adjust the heights of the fill valve and float cup, but other than this it’s simple to install. Takes about a good 30 minutes to complete, I decided to do a good clean up job inside the water tank since it was empty and dry. I read some complaints of packaging being tough to open the kit, well you just need to man up to open and get the job done. I recommend this product to anyone needing to repair a toilet tank slow leak or running water. Fluidmaster did a good job making the kit as a simple DIY house hold fix. Great product, easy installation steps, 5 Stars – ‘nuff said.

Rated 5 out of 5 by from Easy plumbing for dummies This product was so easy to install. I am a 60 year old female and I installed this repair kit and my toilet was operating properly within 30 minutes.

Rated 5 out of 5 by from Easier to install than I thought, works great. All that parts in one package to get the job done right without five trips to the store: nice. Easily adjusted to fit my 60 year old toilet so I'd expect it will fit anything. Detailed, easy to read, step by step instructions should allow the complete idiot to get this in right on the first try with just a few tools. Way better quality that the stuff I took out so I expect this will last pretty much forever. If your toilet runs, just buy this kit and you'll be able to make the fix. Took me about half an hour and I was being really careful.
