Answer: 
1. Replace flapper. (On average, I have to try 4 flappers for each one that actually stops leaking.)
2. Replace the fill valve with one that has some kind of Leak Sentry function. Flappers fail all the time and a Leak Sentry type will keep the tank from filling unless the toilet has been flushed. (If you have a Leak Sentry type and your tank is dry, replace the FLAPPER.)

Check your flapper valve inside the tank. They do tend to wear out and need to be replaced. Kits are inexpensive and easy to install.

Answer: 
From my observations, it seems like the flapper may require attention / replacement.
For me, a cleaned flapper went from loosing 6 gallons (24 L) per day down to loosing only 4 gallons (16 L) per day!
Clearly, the flapper needs attention.

Water running all the time in the toilet could be the result of a few different things. The most common cause is a deteriorated or otherwise non-sealing flapper that is causing the tank not to stay full after flushing – check the flapper to see if it’s properly seating against the flush valve by first turning off the water to the tank and marking the water level.

Water running all the time in the toilet could be the result of a few different things. The most common cause is a deteriorated or otherwise non-sealing flapper that is causing the tank not to stay full after flushing – check the flapper to see if it’s properly seating against the flush valve by first turning off the water to the tank and marking the water level. Leave the tank for a period of time (1-3 hours) and do not flush it, then come back to the tank and check the water level. If the water level is below your mark then you have a tank leak and the easiest solution is to replace the flapper. A less common issue could be an older flush valve rim not being smooth enough to create a good seal with the flapper. This can be repaired with the 555CR Flush Valve Repair kit, or by replacing the entire flush valve and if the toilet has not been touched in years a complete kit such as the 400AKR might be a better solution to extend the life of your toilet. In such cases, you should also replace your toilet water supply connector to help prevent costly water damage that could be caused by a deteriorated water supply line. If the water line remains at its marked level, then you likely do not have a flapper issue. If your fill valve continually runs without a flapper/flush valve leak, the fill valve could be clogged and need to be cleared of debris or it might need to be replaced. The directions for clearing debris from the valve are:
1. If you are attempting this procedure while the valve is already installed into the tank, then it is necessary to turn off the water supply and flush the tank.
2. With right hand, reach under the float cup and push it up. Keep right hand under the float by grabbing the valve shaft and holding it tight. Do not let the float cup drop or the valve shaft turn.
3. With left hand, grab the cap and at the same time place your thumb on the side of the gray/black lever arm (The lift arm that protrudes out from under the top and connects to the adjustment rod) and twist both the cap and the lever arm counterclockwise 1/8th of a turn. You may need to press down on the cap while making a quick twist. The valve cap will unlock.
4. The cap assembly includes; the black cap, lever arm, the plastic housing and seal.
5. To purge debris from the fill valve hold a container over the uncapped valve and slowly turn on water until all the way on.
6. Let water run 15 to 20 seconds or until tank is full.

Make sure the water is not leaking through the flapper. You will know the flapper is doing its job when the water STOPS running. Water is leaking through this flapper. It's possible you might have to replace the flapper. Test it out: open up the toilet's top and watch what happens after you push on the trip lever. The flapper will lift up and let all the water flush downward. Watch the flapper, ensure the flapper is preventing more water from leaking out. If the flapper isn't doing its job, water will continue leaking through, resulting in the float ball (or in this case the Leak Sentry Water Saving Fill Valve) going down, which then controls water output from the water control assembly to push it back up to the water fill line.

Answer: 
The chain on your flapper valve may be getting caught up inside the tank. Remove the lid to the tank and see if the chain is holding the water level float up, not allowing it to drop and allow water to fill the tank.

Answer: 
Open the tank and watch the floater. It should push water out when the floater is down. The water in the tank will start to fill, and the floater will go up, and stop at a certain point. Make sure nothing is preventing the floater from going down after the flush. You might have to change the height of the refill adjuster to assist with this as well, it might be set too low? Hope this helps!

Tank over flow

Arlington, Tx

February 26, 2015
I have a leak sentry fill valve, and for some reason the little lever at the bottom that is supposed to prevent leaks some times gets stuck on the off or on position and causes the water to continue to spray into the tank instead of letting the fill valve to rise and shut of the water, this causes the tank to over flow and leak a ton of water. This has happened to me 3 times now, first two times i caught it within minutes, third time not so lucky, wasn't near the restroom and last time I used it was an Hour before I caught the overflow! 2nd Story too. Not fun to clean up. Now replacing fill valve, is the old ball cock a better solution?

Thank you for your question about the Leak Sentry Water Saving Fill Valve. The problem you described may not have anything directly to do with the Leak Sentry device. The issue here may have everything to do with debris getting trapped inside the valve (in the trap basin under the top cap assembly) and not allowing the fill valve’s master seal to properly seat and turn off. The simple solution to this problem is to remove the fill valve top cap and flush debris from the valve body. The Leak Sentry valve which is designed with a removable top can be flushed and without removing the it from the tank. I think the Leak Sentry valve Is a premium valve that offers greater potential for water savings and would not exchange it for a ball cock fill valve. Read Less

Rated 3.2 out of 5 by 45 reviewers.
Rated 5.0 out of 5.0 by "Cost reduced from 5 years ago. Float height adjustment has been drastically cost reduced from the old one (@ 5/6 years old). This change limits the amount of adjustment considerably. The mounting height can be used to compensate to some degree. Still, the thing is working well, installed ok, and the price was reasonable. Can't vouch for longevity, but for now it's working well. March 4, 2014

Rated 5.0 out of 5.0 by Fluidmaster 400 lsc leak sentry WORKS! The device was easy to install. It works like a charm. Even if I didn't think so at first! I made the same observation as previous reviewers: the tank was empty and the toiled "didn't" flush. Yet I concluded differently. The (my) unit works perfectly well. As advertised, the unit DOES "prevent the refill of a leaky tank." While I was puzzled at first and did think the unit was faulty, I removed the tank top and looked inside. The tank was empty! And that was clearly no fault of the Fluidmaster400 lsc; the unit did perfectly well to "prevent..." I took a look at the flapper and, after 6 years, it was pretty crusty; a perfect setup for water in the tank to seep through. An early, rough, observation had my tank emptying in about 4 hours. That is 6 "emptyings" a day at a gallon (4 L) per! Six gallons (24 L) per day. 365. Wow. I cleaned the flapper and the rate slowed to about 6 hours per emptying. Down to 4 gallons (16 L) per day of wasted water. In that toilet alone! Clearly, it is the seal with the flapper that is the problem. This weekend, my pet project will be... I hope this helps.

Rated 5.0 out of 5.0 by Tremendous Value Some years back, a basement toilet flapper valve leaked over 75,000 gallons of water before it was discovered. We have high mineral content water and the minerals crusted on the flapper valve. I installed the Leak Sentry fill valve (and new flapper valves.) I hadn't paid attention to that bathroom for several years, as it is remotely located. The other day I was down there again and flushed the toilet. Thank goodness the leak sentry had prevented the toilet from running, as the tank was bone dry. Again, the flapper valve had been encrusted by minerals and was leaky. All of my toilets in my rental houses have these valves and it saves money and water. February 19, 2015
Rated 1.0 out of 5.0 by Valve won't shut off. The unit was fairly easy to install, but the plastic chain took a bit time to get hooked to the right spot on the lever arm. However, after a week of light use, it whistles and is leaking (water going down the overflow tube). I had just replaced a similar unit (only a month old) after doing a bathroom remodel and thought the valve seals had maybe dried out from sitting in a hot garage as it leaked too. I guessing it's debris in the water line, but I certainly can't clear it out, or take the valve apart (it looks like it would just break trying to work on it.) I would like to buy something more robust (maybe less plastic parts?) October 14, 2014
Rated 5.0 out of 5.0 by quick and easy and works like a charm. A quick and easy way to fix a leaky toilet,I was really impressed with it and the price was right. August 5, 2015
Rated 2.0 out of 5.0 by Worked for 2 years, then won't allow tank to refill. I have a new house (2008), with 5 toilets in my house, about 2 years ago (2012/2013), we had high water bills so I changed out all of the factory toilet fill systems with the Fluidmaster 400LS. Immediately we noticed an improvement in our water bill and performance on refills. Now, 3 of the 5, the ones used the most, won't refill. These have been working fine, nothing has changed in the system or usage. I have re-adjusted the chain from the original position and I cannot solve the issue. I left it loose, i left it tight, to the point you could hardly move the handle and all positions in between (2-3 links in the plastic chain), and it is very difficult to move the handle far enough to get it to flush or it short flushes. This item has a 5-year warranty for performance, but who can find a receipt after a few years? Going back to buy 3 from Home Depot, will bring back the defective ones on that receipt, what else can I do? I have spent more than 3 hours total over the past 2 weeks trying of work this issue out. July 5, 2015
Rated 1.0 out of 5.0 by Poor quality When the toilet goes to fill back up the float device on this thing takes too long to raise up to stop the flow. I tried fixing it and adjusting hit no use. I just have to spend more money for he better quality instead of this cheap plastic. July 7, 2015
