What you are experiencing is a flapper valve problem. Since I don't know what model you have I will give you a link to the generic GMax unit. Here is the parts breakdown for a GMax

Toto GMax

I would suspect you need part #7 on this diagram a flapper valve. Take the old one with you since different colors ones are used on different models. You should go to the Toto site to locate a dealer first. You can find their site here:

Hope this helps and please remember to rate this!

If this is one of those models that most people have, the valve that shuts the incoming water off when the tank is filled is probably bad. It only costs about 8-10 dollars to replace. This valve is actually a stem or tree shaped device.

You might want to try and lubricate the rubber gasket with some silicone grease or plumbers grease. If that doesn't work, follow this link. I'm sure there is information for your toilet at the Dometic website. http://www.dometic.com/enus/Americas/USA/Customer-Support/

SOURCE: Toto fill valve continual problem, new toilet

There are cheep fill valves and ther better built fill valves, so make sure you buy aa quality fill valve. Also buy a pressuer gauge at ahard ware store and check water pressure level at a faucet outlet. Screw gauge onto water fauct leave a little room for air to escape when water is drippng out tighten the hose bib on the gage turn on the faucet and read the pressure. If it's more than 50 PSI you need to lower the water pressuer. I need to know if your on a, on site underground well,or are on city water to tell you what you need to do to to fix this problem. If there is one. thanks for using Fix-ya if you want more info post here.

SOURCE: Continous water running

just lower your float a little further. otherwise i'd adsume air is leaking out of your float. but if your float is up in the shut off position and water is still coming out. then you need a new assembly.

Toto neorest leaking & low pressure wand


Sounds like the washer in the shutoff at the wall has failed and is partially blocking the fill pipe. Some rubber from it may have gotten into the toilet valve internally. With the wall valve closed, try to remove the connection pipe to the toilet. If you can do it without water continuing to flow out of the wall shut off...then remove the pipe from the wall shut off. Flush the toilet. Now, apply air pressure to the rubber hose the goes into the overflow pipe. That may clear the valve in the tank and solve both problems. If you cannot stop the water at the wall shut off, close the water valve feeding the house. Remove static water pressure by opening the cold water a the kitchen sink faucet. Now you can open the wall shutoff valve and replace the washer and clean it out....

How do i flush the pipes out? (when i flush the toilet it will not re-fill water) one of the answers was to flush the pipes


If you have a supply shut off to fixture shut it off and disconnect supply line from inlet to toilet . If your supply line to toilet is a flexible line then bend it so that you can direct water to small container. Slowly turn valve on to see what flow rate is at that point. If flow rate is not good then I would shut water off to house and replace valve. If flow rate to toliet is good I would reccomend you replace flush vallve. To do this shut off water supply to toilet. Disconnect supply nut to bottom of flush valve. There will be a retaining nut that holds flush valve in place in toilet tank. Remove flush valve after removing fill tube from flush valve to overflow tube. Replace with toto replacement valve or use Fluidmaster 400A. Instructions on box of 400A are easy to follow and if you have flex connector you won't need supply line washer. I would reccomend that before you install new valve that you put rubber gasket on shank of valve and slid it about halfway up the shaft. Make sure that inside of tank is dry and use a small bead of silicon caulking on top and bottom side of shaft gasket. slid gasket the rest of the way on valve shank,install in tank and put on retaing nut hand tight. Push down on top of valve and using channel lock pliers finish tightening nut securely.You may need to reach into tank and grasp valve body to stop it from turning. There are other things you can do if you have a working supply valve. Shut off valve and remove screws that hold top of valve in place and remove and clean surfaces. You can turn valve on slowly to help flush out any rust or mineral deposits. I hope this is of some help to you. Thanks

Toilet flushes fine but when the tank has filled it seems like the float ball keeps bobbing up and down letting more water or air into the tank. it will do this 5/6 times then quits. its almost like it is...


The ball float follows the tank water level, and repeated cycles of the float dropping and opening the fill valve would likely reflect a leak in the flush valve. You could try adjusting the float arm downward so that it will respond to a lower water level. Try turning off the supply valve, flushing it and listen for water leaking past the flush valve after it closes. If it does, replace the flapper or adjust the chain.

Toto toilet does not flush properly - insufficient water to make it flush properly - need to pour water down toilet for it to flush. There is not any kind of blockage.


Check water level in tank for proper height it should be about 5/8 close to top of stand pipe in tank or it should have a mark on it wher it should be.


You can adjust the flush valve to increase water height.

My toto toilet has both 1.6 gal and 6 gal flushes. the short flush doesn't go down.


I am not a toto expert but i think i understand the gravity control toilet concept.A gravity flush tank type toilet flushes do to the force of water traveling from the tank to the bowl in a small passageway and forces the water in the bowl towards the integral trap in the toilet.In other words the water isnt dumping quick enough or the passageway is restricted.,My guess is the flush valve isnt dumping all at once.

Toto CST853 cistern will not refill. Was fine yesterday. City is working on pipes and broke a water main last evening, all other faucets and toilets are working....can I clean the water filter or does it...


alot of times you can turn the water off to the toilet and the tops of the fill valves usually pop or screw off. then if you put a small cup over the top of the fill valve you can turn it back on and flush the debris out and put it back together. if its a fluid master type you can pop the top off it. and turn the float arm a 1/4 to half turn and the whole top will come off

Toilet will not flush


You need to replace the fill valve with a oem replacment valve. You need to use toto parts.

I have a toto toilet. After flushing it is taking a very long time to fill up.


Make sure that the fill valve doesn't have debris caught inside near the valve needle. Also the tube that attaches onto the flush valve can become clogged near the fill valve as well. Remove the hose and then take a needle and try and clear the outlet. Blow through the tube to insure that it's not blocked as well.

I purchased a Toto Aquia II Dual Flush Toilet, around a year ago. No problems until now. The toilet won't flush. It doesn't appear to be running at all.


If this is one of those models that most people have, the valve that shuts the incoming water off when the tank is filled is probably bad. It only costs about 8-10 dollars to replace. This valve is actually a stem or tree shaped device.
