I just replaced the water supply valve and metal tubing with the flexible tubing and noticed mildew all over the bottom of the tank on the outside. After observing the toilet during flushing I noticed that water shoots up out of the overflow tube several inches, and hits the lid, then runs down the back of the lid and onto the back of the tank where it accumulates on the bottom of the tank.

Is this normal? If so how do I stop it? I also observed water continually running into intake valve, even though I couldn't hear it running, I could see the water moving around in the intake tube. So I will be replacing the intake valve, but it doesn't look like that will affect the overflow tube shooting water.

Any ideas?

 

There should be no water shooting up from the overflow tube if everything is set-up and functioning properly.
Replace the tank water valve with a Fluidmaster 400A float-cup type (about $7-$8 bucks). Easy. Just follow the directions that come with it.
The flex water tube from the new tank supply valve should be clipped to the top of the overflow tube, and the water flow directed downward into the overflow tube.
There should be a horizontal indentation inside the tank wall that indicates the proper water level at cut-off, which should be at least 1/4" or more below the top of the overflow tube. Adjust the float (pinch the clips on the side rod and slide it up or down to adjust the water level) to shut the incoming water off at the proper level.
Good Luck!

Thanks for the reply. I will try what you suggest. But I did notice that even when the tank has only filled halfway and I flush, water still shoots out the overflow tube, but not far enough to hit the lid.

 

When you properly install the new tank water valve, that problem should be solved.
Good Luck!

And it was! I got the Fluidmaster 400AK something rather, complete kit and replaced everything including all the bolts. Seems to work much better now and the tank even fills 10 times faster. The only odd thing is if I set the flapper volume setting to anything less than 9 it closes before half the water is out of the tank, but other than that it works great. I also put some plumber's grease on most of the gaskets even though the instructions didn't mention it.

Thanks for your suggestions Mike!

 

Hello: Uter

The flush holes around the underside of the bowl rim may be restricted with hard water and or calcium deposits.

In some cases, hard water deposits can restrict and or clog up the water flush holes around the underside of the rim around the bowl. Therefore, the water flows out without sufficient volume and force to fully complete a total flush. May also cause the water to backflow up out of the overflow tube.

Muratic or Phosphoric Acid can be poured down the over flow tube inside the tank. Allowing this de-liming chemical to remain in the rim of the bowl for several hours or overnight, will loosen the hard water and lime deposits.

Upon the next flushing, the deposits will flush out with the water and normal flushing will resume. Heavy deposits may require two or three repeated treatments.

May also need to use a wire end of a coat hanger to gently move around up in those flush holes to further remove loosened depsoits, etc. Not exactly a pleasant task but may help. Once that is completed, flush again to remove lossened deposits, etc.

Visit the local hardware store and inquire about the products mentioned above. Follow the mfgs instructions if any are porvided. Ware eye and hand protection. Both chemicals are corrosive. Read the labels.
