Toilet will not fill after placing tidy bowl automatic cleaner in tank. Took the cleaner out but tank will not fill on its own. Help!!

The tank holding the proper amount of water is a good sign. The inside of the stool is like the GOOSE NECK under you sink. It always holds water. This may sound like a bit of a hassle to do but if all 3 toilets are identical, here is what you can try if you are a bit handy. Go to the hardware store and purchase 4 toilet wax rings with a plastic flange and a few sets of toilet floor flange bolts(they are cheap and you can always return if not used, as It is better to have xtra parts on hand). Turn off the water supply to the "Mystery Toilet". Leave the tank and everything connected to the stool. Flush the toilet and remove all excess water from the tank and bowl. This can be done with a shop vac, sponge or towel. Disconnect the water supply to the tank. Remove the bolts holding the stool to the floor and carefully remove toilet. Scrap off all the old wax from the floor flange and bottom of stool. Now go and repeat this proceedure to one of the toilets that is working properly. In other words Switch the "Mystery Toilet" with a "Working Toilet" and see how they react. If the working toilet does it in the same bathroom and the "Mystery Toilet" does not do it in the other bathroom then you probably have a VENTING PROBLEM. If the "Mysery Toilet" Does it in the other bathroom then you most likely have a Defective Toilet. This Job is best done by 2 people, as it can sometimes be challenging to center the new wax ring on the toilet flange. Reconnect to the floor and reconnect water supply to the tanks. DO NOT OVERTIGHTEN BOLTS to the floor flange as you may crack the toilet. All drain lines must be vented properly for water to flow. If you are curious check out drain venting on the internet. Also, sometimes a vent can become obstructed with debris, ice, bird nest, etc.. I would 1st check the vent on the roof visually and then have someone flush and listen. If you believe the vent is clear....Then do the toilet switch and go from there.....Hope this helps and Happy Holidays....Joe

SOURCE: Toilet tank not filling

shut the water off to the toilet .Remove the toilet supply from the tank end.slowly turn the valve on to see if their is any water coming thru the supply.If water is coming thru the supply than you know you need to change the ballcock.This is the part in the tank where the water comes out of.

SOURCE: Toilet will not fill up

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.

I would change out the flush valve itself...it will come with the right gasket....it won't cost anywhere near the price of a new toilet...and it will save you time in the long run..good luck and.thanks for rating my effort....the fang.

Check your flapper line to the flush handle. The flapper is in the tank on bottom. There shoiuld be a plastic line to handle or chain. :)
