Pegasus toilet tank will not refill

You probably have one of the newer Cimarron-series toilets that feature what Kohler calls "AquaPiston" technology. These gadgets use the water pressure in your supply lines to pressurize a charge of flush water in the tank, causing the flush water to rush into the bowl at high pressure and velocity. Many Cimarron-series toilets use only 1.28 gpf (gallons per flush), compared to the current industry standard of 1.6 gpf for conventional gravity-flush units. Reducing the gpf rating by 20% requires pressurizing the water in the tank, and the release of pressurized water makes a lot of noise. I'm afraid your toilet will always be noisier than what you may be used to.

hiya:) This is a result of a very minor design error (i am a big fan of FluidMaster products) combined w/a slightly higher than normal water pressure situation or foreign matter stuck in the valve somewhere. try turning down the water pressure via the shuttoff under the toilet tank:)

Pressure assisted toilets have a stainless steel tank that refills under lid,if your refilling bowl it only needs to fill trap for smell,the pressure assist does the rest,thats part of the water saving of the toilet,you don't have a lot of water in the bowl

it is filling up too much you can adjust the arm there is a screw on the side that adjusts the leval of water in the tank

Maybe the shut off valve is not open all the way .....
can you adjust the fill valve so that more water comes into the tank ... more water more flush !

You need to replace the tank flapper valve gasket.

sometimes if you change the flapper and add more water to the tank by adjusting the fill valve they will flush with more power

make sure the fill valve is not cracked,that's the long tower looking thing on the right side of the toilet when you stand in front of the unit. you can replace this part at homedepot. it is called a fluidmaster 400A.good luck.

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!

yeah sounds as though the ball valve or water inlet valve is stuck in the closed position or jammed so when you flush the loo the water doesnt refill.
Isolate water service remove valve as required clean/replace re instate test & leave working
