Please respond ASAP - I won't have Internet access after 40 minutes!
My model is black with a white cap.
The toilet w Problem: Debris is lodged under the valve's seal. Debris may consist of calcium deposits, minute pieces of corroded pipe, rocks, rubber, solder, etc. that are carried by the water stream to the seal area, where they become trapped. Some well systems without a filter constantly circulate debris.
Solution: Shut off the water supply and remove the valve top (Model
400A: lift arm first). Cover the opening with an inverted cup, and turn water on and off a few times. This should flush and remove water line debris. Turn top assembly over and clean seal surface by rinsing under water. Replace top (400A: lift arm first) by rotating clockwise.(end)
Nice, except that when I tried it, I couldn't get the cap off (yes, I twisted counterclockwise). Prying didn't do a thing either. I'm afraid I'll break it if I put any more pressure. What am I doing wrong?
Granted, another possible solution was listed here, which I'll try in a few hours:
Solution: Reset tank water to a lower level by using the water level adjustment clip (see illustration) located on the link of the valve. Squeeze the two sides of the metal clip together, then slide clip down the rod.
Again, please help ASAP - the plumbers are inspecting the building tomorrow and I'd rather do it myself. Thanks.
Lenona.
