Are there any chemicals in the tank?
I have a newly installed one-piece Guinevere Toilet. Approximately 50% of the time the flapper lands off center and distorts after closing and allows water to leak around the edge causing the toilet to run continuously and often making a strange whistling sound. I do not believe this is an installation problem. The flapper attaches to the drain in only one manner. The flapper seems too soft and flexible. Toto sent me another identical flapper and I have the same problem? I am thinking of adding some plastic to the back of the flapper to stiffen it enough to prevent this problem. I can't be the only person with this problem, can I? Toto needs to manufacture a stiffer flapper to correct this problem. With the water running so often instead of saving water we are wasting water with this new toilet!
No chemicals. It is a brand new toilet. The flapper literally lands off center and then by the strong suction gets sucked partially into the drain.
Is the brass rod bringing it offcenter?
If that were the case, a slight bend may help.
I've been selling dozens of these, and haven't seen that before.
TOTO uses the same flapper on everything.
So the flapper is on thousands of units that I've sold.
Yes, I think the flapper is pulled slightly off center by the brass lever arm, but so far I have been unable to adjust it so that the pull is enough when it is on center. I will try again. I do believe if the flapper were stiffer this would not be an issue. Thanks for the advice. Evan
I could not adjust the lever to avoid pulling flapper off center. Instead I cut a small piece of the white plastic chain sleeve and put it on the back drain-flapper connector hook to create a washer buttress to keep the flapper from sliding towards the front of the tank and off center. Not sure that I am describing well, but it worked. The other solution for Toto would be to allow less play in the area where the flapper attaches to the drain hooks. Thanks for help. Evan
I had the same problem, also installed in last month or so. (9/21/2009) I used tie wraps on inside of flapper hinge both sides and is working, after getting clued in by reading the washer suggestion (thanks).
I installed my new Toto Guinevere and the dam thing wont seal at the flapper, Ive removerd it and checked it for burrs and found nothing. it continue to slowly leak the water out of the tank.
Toto is sending me a new flapper assembly, but damm for what these cost you think the thing would just work.
Is there any thing else I should check?
By the way this Toto is loud.
Terry I did that and thought it helped but it still dripping and loosing water in the tank.
One thing I did notice is that the flush handle is pulling the flapper just so slightly to the side. Should I bend the rod to have it lift it straight up? or is the way this model works? (Handle pulls froward)
Were going on vacation and I need to get this resolved ASAP
Ok I took the fill tube assembly out again and found there to be a porcelain bump on the inside edge of the hole, I tried to us emery cloth to smooth it out but didn't have much luck.
The new parts Toto are sending me didn't arrive today and was now told they wont be here until tomorrow.
Do you think its the bump on the inside of the hole thats causing it to leak? and now what should I do?
ok Im letting is sit to see if its still leaking.
The bump is defiantly on the inside edge of the hole.
New flapper and fill tube are installed in the new Toto, it seems to be holding water.
The tech team at Toto were great to deal with, and I will be buying another Toto for my other bathroom.
Thanks for the help Terry
