There should be a number stamped into the tank.
I have a toilet which frequently gets plugged in my 1986 manufactured home. The toilet may be original; I don't know since I've only owned the house for 5 years. It says "Gerber 1.6gpf" on it. 1.6 gallons per flush, I believe. My other toilet is nearly new and has never plugged up. I have a septic system. Does anyone have any ideas on how to fix this problem? The toilet probably plugs up once or twice a month. Before I get too many wisecrack answers, I will say that I know how to use a plunger and have done so many times. When I say "fix this problem", I mean to prevent it from happening. THANK YOU.
A 1.6 gpf toilet is likely NOT from 1986, but could be. In any event, if it is anywhere pre-2000, as a 1.6 it is a very poor flusher. That said, without being too graphic....if there is not a drain issue on that line, it could relate to what you put in it! For starters, stop using Charmin or any soft multiply tissue like that. Get some el cheapo Scotts or Kirkland. There is a BIG difference in flushability of papers.
Just to expand Jimbo's comments a bit. Early low flow toilets were a bust. Manufacturers tried to make their old water hog designs work with less water. The results were predictable; frequent clogs. Unfortunately, some manufacturers still are trying to tweak the old designs with fancy flush valves and pressure assisted flushing. Toto saw the problem early on and knew the internal designs had to be changed. The results were toilets that performed well while meeting the new standard. Over the 20 plus years of the low flow requirements, Toto has continued to improve their designs so that the newer models now perform well with only 1.28 gallons per flush. Few Toto owners report a clogged toilet, and most of those who do experience one find the cause is something being flushed that was not intended to be. Children's toys probably lead the list, but other things can cause the problem as well TP also makes a difference. I have found the cheap house-brand paper sold in chain stores to be the best.
If you can get underneath, you may want to check that that pipe is sloped properly without humps or dips...

To Terry Love,
The numbers on my Gerber toilet tank (stamped inside) are "6 15-02 2". There may be dashes between all the numbers but, if so, they are very faint. Thank you.
Thanks to Terry and everyone who replied. Looks like I will be replacing a toilet sometime soon, so Terry's consumer toilet reports will come in handy. Thanks again.
And, a definite plus for you is that you are just a hop, skip, and jump down I-405/Highway 9 from Terry.
