You don't have to replace, You just need to adjust the fill valve. If you have the ball **** type just tight the top phillips screw. If you have the newer type, close the water valve under the tank and Push down a plastic ring at the bottom of the filling valve, Push down the top of the valve, lift the plastic ring to it's place and open the water valve.

Sorry to hear your having problems with your toilet. The part in the back of the toilet that has failed is called the fill valve. The best solution is to order the new part from Toto as original manufacture parts tend to work best. Their parts site is https://www.totostore.us.com/Default.aspx. Depending on the type of fill valve you may be able to find a universal replacement at your local hardware or plumbing supply store. You will need to shut off the water supply to your toilet. Flush the toilet so that most of the water is out of the tank. Remove the remaining water in the tank. Disconnect the cold water supply line at the toilet. There will be a nut underneath the toilet tank holding the fill valve in the tank. Take the fill valve to the hardware store so that you can get the closest replacement part possible. They come in different heights and styles so be sure to get the best fit. If you're not sure the universal replacement will work then order the proper replacement part from the Toto website. Good luck with your project and let me know if I can be of any further help. Have a great day.

How to fix a running toilet


Please remove the lid from the tank on the back of the toilet to see wherein lies the problem.
You may find the flapper stuck in the upward position.
The flapper is usually black rubber, and is supposed to cover the drain hole in the middle of the bottom of the tank.
Flappers can turn your hands black if you touch them. Not a joke.
See if simple jiggling the handle will cause the flapper to work properly.
The regulator mechanism can also be worn out. That is the assembly that refills the tank after it is flushed. That can also stick and the water keeps running.
You may determine which of these is your problem.
God bless your efforts.

Tip

What to do if your toilet stops working


When a toilet stops working it can be a major inconvenience. If your toilet isn't working right, try the simple fixes below.

If the toilet doesn't flush:

When you jiggle the handle, nothing happens. Remove the lid from the toilet tank and peek inside. Most likely, either the chain came off at the lift rod or flapper end, or the rod broke in half. If the chain came off the rod, you can simply reattach it. (Finding the right amount of slack will take some trial and error.) Likewise, if it came off of the flapper, it can easily be reattached.

If the lift rod (the arm attached to the handle) is broken, you can purchase a new rod and handle assembly for a few bucks at just about any hardware store. A plastic nut holds the handle into the side of the tank and the whole assembly can be popped out and replaced. Once you've installed the new assembly, reattach the chain.

If the toilet keeps running:

Remove the tank lid and watch the toilet as it flushes. You'll probably see that the chain is too tight, causing the flapper to not close all the way, which results in water continuing to drain out and having to be replenished. Loosen the chain a little and see if it fixes the problem.

Another cause of a constantly-running toilet is an improper float height. The float is the balloon-looking thing that sits on the end of a shaft and falls and then rises when the toilet is flushed. When the float reaches a certain height, the fill valve is closed and the water stops flowing. If your toilet is running longer than it should, push down a tiny bit on the float and see if it stops running. If it does, the float just needs to be adjusted downward a little (by turning the screw at the other end of its shaft). You may need to try a few different heights to determine the optimal position of the float; adjust it slightly and flush the toilet, then adjust it again if necessary.

If there's not enough water pressure:

The chain may be too loose if there isn't enough pressure. With the tank lid off, watch the toilet flush. If there is too much slack in the chain, the flapper may close prematurely, reducing water pressure. Tighten the chain and see if that makes a difference.

Loss of water pressure can also be caused by the holes in the toilet bowl getting clogged up. There are little holes all around the side of the bowl, where water is forced into the bowl to refill it after a flush. If any of these holes get clogged, clean them out with a round file, a nail punch, or a similarly-shaped instrument. (Don't push too hard or hammer on the bowl.)

If the toilet overflows:

If your toilet overflows, the first thing to do is to turn off the water to the toilet. There is a valve on one side of the toilet, where the pipe runs from the wall to the toilet. Turn this valve clockwise to close it.

Once the water is off, use a plunger to try to clear the clog. If it works, you'll see the water drain out of the bowl. If the plunger can't clear it, try a simple drain-cleaning tool like a Zip-It or Turbo Snake. If you don't have anything that can remove the clog, or if the clog remains even after trying to clear it, you'll need to call a plumber (or buy yourself a closet auger or plumber's snake).

If you are able to remove the clog, turn the water back on and flush the toilet to make sure the clog is completely gone.

There are two holes in the top of the bowl where the tank attaches. As you indicate, one hole delivers water to the jet at the inlet to trap passageway, and another smaller hole to direct water to the rim.

I have seen in some cases the gasket that seals the tank to the bowl block the smaller rim-fed hole. All you need to do is knotch the gasket where the hole is located and re-install the gasket so the knotch is located over the hole. If you have any other questions please call the 800 phone number on top of the Flushmate.

Yes water can back up in a drain and flood out lowest opening, which would be a toilet flange at floor level.
If tub is draining fine, then clog is probably near the toilet, but below floor flange level, and therefore not inside the tank ... judging from your description.
If you are in a house, go outside and see if there is a vent stack on the roof directly above toilet. If so, you can run a snake down from there.
You can also run a snake down through "s" shaped toilet trap and enter the pipe that way.
Another option is to remove the toilet and run snake directly down hole, and then reattach toilet.

My mansfield toilet 160 has a weak flushing problem


My toilet had same problem:
I thought it was a clog in the drain pipe.
But the problem was clogged holes where water flushes into toilet bowl.

Here's how I fixed problem.
Purchase:
Gallon of CLR calcium-lime-rust remover from Home depot.
Pumice stone from hardware store.

Home supplies:
Cut off bottom of empty clorox bottle to make container for CLR
Old 3" paint brush you don't use for anything else to apply CLR
Small cup to pour CLR into toilet flapper opening

Steps:
Look inside toilet bowl under rim and see holes where water comes out
Use brush and apply CLR to holes where water comes out.
Use pumice stone to scrape ... pumice stone will not hurt toilet surface.
Flush toilet to clear holes so far.
Turn off water to toilet.
Open flapper to drain tank.
Keep flapper open.
Use cup and pour dose of CLR directly into flapper opening.
(You can also pour CLR down overflow tube... but flapper opening puts whole dose directly onto problem)
Pour another cup of CLR into opening.
Notice how CLR starts coming out the holes into bowl.
Pour CLR down flapper hole until it runs easy and fast out of holes.
Close flapper, turn on water, toilet fixed.

Saniflow pump keeps comming on without flushing toilet


Water pressure makes the unit kick on and off. If it's turning on by itself then most likely somehow water is draining back into the pump. It could be leaking water from the toilet tank, to the bowl and from the bowl to the pump. Or the check valve inside the discharge elbow may not be closing all the way down and is allowing waste water to drain back into the pump creating enough water pressure that makes the pump kick on and off. Inspect the flapper on the flush valve and the check valve on the discharge elbow on top of the macerating pump.

The toilet is only 2 months' old. The water keeps


Remove the top of the water tank.
check to be sure that the flush cover (about in the center of the tank) can close all the way. It seats into a 2 inch hole - and must seat all the way around. If it fails to seat, then the fill valve (on the left side of the tank) will continously let water into the tank.

As a starter experiment, you may try just turning whe water off at the wall shut off. Then inspect the tank to confirm that it is losing water.
If confirmed, then the above solution is correct.
If it is not losing water, then the fill valve is faulty and will need to be replaced (it is allowing water to over flow into the "OverFlow" tube.....

I recommend that you keep the water turned off at the wall until the toilet is needed - and the problem is repaired.

Slow and incomplete flush. material does not go down or some comes back.


Clean out the holes under the rim where the water comes in from the tank. Mineral deposits can clog these. A stiff piece of wire (coat hanger) will work.

Also, if the toilet has the siphon hole at the front part of the bottom of the bowl, this can get clogged with mineral deposits. These deposits can become almost rock-like and can be very difficult to remove. Try using a short screwdriver and break these loose. Water must flow freely from this hole for the toilet to flush properly.

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.
