I just finished remodeling two bathrooms, both of which had ten year old Toto Drake GMax 1.6GPF's in them. So I am very familiar with how they are supposed to work, at least in my house. Well for the remodel I bought one of the old Gmax 1.6GPF units right before they became illegal in California, and had to get the Eco 1.28GPF EMax for the other bathroom. Of course before doing that I consulted this site to find out what people were saying about the EMax especially Terry. Anyway, I had the new Gmax installed and it worked exactly as well as my old ones. Then two weeks later the new EMax went in and the next thing I know my wife is screaming at me that the new toilet was broken and I had to get it fixed now! So a few days later I looked at it and she was absolutely right. The Emax had a very weak flush, and even if I held the handle down, it got more water, but still with a weak flush. Btw, both of the new toilets came with the new Tower style flush valve. So just to make sure, I went up and down the stairs several times(the bathrooms are on different floors) checking the flow on both, and there was no doubt about it. So I got the plumber back today who looked it over, but couldn't find anything wrong. He did adjust the flow on the tower to increase it, but that didn't help either. He also has the same Gmax model at his house, and agreed that this new EMax had a very weak flow but couldn't figure out why. He guessed that it could be a manufacturing defect in the bowl, but didn't have a camera with him to check it out. So I went to the Gmax and timed the opening of the tower from when I pushed the handle down to when it stopped releasing water and it was roughly 1.5 seconds. When I did the same thing with the Emax, it closed in .5 seconds and it closed with what I would just guess was about half the amount coming out of the GMax. Btw, there are no leaks anywhere, and the tank is seated correctly. So my plumber thinks it's a bowl problem, and I think it's a tank problem, but could it also be a tank problem being caused by a bowl problem also? Whew!!! Any suggestions would be appreciated before I just go drive across state lines and get me a GMax?
Btw, I'm already kicking myself for not having my plumber switch the Gmax tank with the Emax tank to isolate the problem to the tank or the bowl!
