Toilet will not fill up

After flushing I have to turn the main shut off supply valve to the toilet
other wise the water just trickles and does not fill the bowl. Turning the valve off and then on after flushing allows the tank to fill up.

    If a normal style tank, buy an ajustable height fluidmaster and replace the valve. I have had better luck with this $8 valve over the last 20 years that I have had with tank type fill valves costing as much as $40 each.

Some Toto fill valves have a plastic debris screen located at the inlet connection. Turn off the supply valve and remove the supply connection at the bottom of the tank. Use a mirror to inspect the screen for debris.
I agree w/ Smithbrother, the Fluidmaster fill valves are cheap and work well. The only thing they ever need is an occasional seal for $1.50 and 5 minutes to replace.

After a flush, water tank fills up but water will not shut off automatically, have to shut off the main water supply at the bottom of the toilet after each fill up.


There is a problem with your fill valve. The fill valve has a float connected to it, that rises up as the water level reaches its correct level, which then shuts off the water entering the tank.
Replace the fill valve. They run in the neighborhood of $10-15.

I have a uberhaus dual flush toilet. I turned off the water supply in the house to work on a sink and when I turned it back on the toilet won't fill anymore. If I fill the tank or the bowl it will flush...


You will have to disassemble the fill valve and clean it. When you shut the water off and on to work on the sink it dislodged dirt and scale in the water piping which clogged the toilet fill valve. Check your lavatory sink areators too they may also be partially plugged. Hope this helps.

My toilet keeps running. I tried to adjust the float with a phillips but that did not work. There is slight leaking into the chamber over the top.


If there is a continual leak in to the toilet bowl you will likely need to replace the flush valve or the toilet flapper.

As a first step try try cleaning the sealing surface of the flush valve to se if the flapper will seat and make a seal.

If this does not work and the flapper is visibly detioriated and breaking down shut off the water supply, remove the toilet flapper and visit your local plumbing supply store to purchase a suitable replacement. Install the new flapper, turn on water supply.

These illustrated instruictions may also assist:

Although less likely, if the sealing surface of the flush valve is damaged or detioriated proceed with replacement of the flush valve. Again turn off water supply and follow the instructions set out here:

http://www.danco.com/HowTo/How-To-Replace-a-Flush-Valve

If there is not a leak in to the toilet bowl and the water flow does not shut off completely, then water is flowing through the fill valve and the overflow pipe and you may need to adjust the float and float rod to allow clsoure of the fill valve. See here:

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

You can buy valves and fittings at Home Depot and other repair stores that do not require any torching. They only require tightening. Measure the widths of the lines going into and out of the valve and go to the store and tell them that you want a compression fitting valve with the appropriate dimensions. Good luck!

Toilet keeps filling tank every 10 minutes doesnt sound like its leaking no water around toilet or on floor still flushes and opertes..just water trickles on every 10 minutes or so to top up


If there is no water on the floor then the water is leaking down the main tank drain. Take off the tank lid, turn off the water supply to the toilet. Fllush as much water out as you can. Look at the main drain, sometimes if the flapper valve is connected with a chain, the chain can get caught between the flapper valve and the drain hole, the flapper valve is pliable so it tries to seal around the obstruction but can't always do it. Make sure there is obstruction, that the flapper valve is not out of shape or old and non-pliable and that it lines up with the drain hole and doesn't get "hung up" on anything.

Downstairs toilet won't stop filling, upstairs toilet won't fill


for the upstairs if the valve is fully on there is not much you can do other than replace water service to the house or heaven forbid repipe.Valves usually don't restrict fill volume.But you can take the supply loose from the tank and stick it in a bucket turn the valve on and check the flow.this should narrow it down.Down stairs repair or replace flush valve

Toto Toilet - no water flow to refill tank after flush


Remove the tank lid and look at the fill valve. Is it a yellow valve?
This fill valve is common on the Toto Toilets and can easliy plug with debrie.

They can be disassmbled and cleaned. however, I usually just replace the valve with Fluid Master Fill valve.
You will also want to check the water coming into the toilet by turning off the water that supplies the toilet and disconnecting the water supply line. After removing the water supply line turn on the water at the valve to make sure that the water is flowing properly. Check the supply line also to make sure it is not plugged.
Be sure and place a small container to catch the water that will come from the valve. A towell will also help from making too much of a mess.
If the Supply line and the valve are clear the problem is in the fill valve.
The G-Max system denotes the Flushiing system which is a 3" flapper that allows the water from the tank to flow into the bowl quicker.
Good Toilets!
