    We are fortunate to have three full baths in out home. I was wondering if you could help me with this question/ I have all 7 gallon toilets in my home. All,.. on two sewers.She cleans then every week and uses "iron out" I think the porcelain glaze is getting kind of rough 'the shine].Will 3 gallon toilets get the job done on this long of a run....clear to the main, in the street? Theres just her and i here, and the dog,and the dog would rather go outside:D thank you if you need more info let me know bob s

    This sewer is all pvc..installed right. never have had a stoppage in 20 years.

    My parents home has one 3.5, and two 1.6 bowls.
    It's 250 to the street sewer with 4" clay lines that were installed in 1962.
    Never a backup.

    Where will you even get 3 gallon toilets? They have been illegal for over 20 years. You need to understand that toilet waste does not flush through the entire waste line, even short ones, with one flush.

    I have the toilets mixed up.. I think.. what was the standard water amt 25 years AGO?/ My toilets are the large tank, that i rebuilt mine to/for this long sewer.. I am thinking they are 7 gallon . am i right?The newest toilets are 3.5? and i want to change over to the newest size. just don't want sewer trouble.

    The old big ones are 3 not 7 aayy Gary. i have forgotten a lot since i retired from plumbing along time ago bob s

    yes they might be illegal. but its my choice.plugged sewer or get caught. right?,

    In the mid 80's, toilets went down to 3.5 gallons
    In 1992, they went down to 1.6
    California now uses 1.28

    I really don't think you have anything to worry about.

    FWIW, Toto now has a 1g flush toilet that gets good reviews. Toilets will continue to decrease their water usage as technology and water issues evolve.

    "Waste does not flush waste" through the waste line???????????

    He is saying it takes more than one flush for "toilet waste [to] flush through the entire waste line", and even with the short lines.

    NOt all toilets are created equal, just like not all cars are, or pretty much anything made in this world. Some work quite well flushing with the mandated lower water usages...some, even some of the big old brand names, do not. As a brand, my experience with Toto has shown them to be good both in performance and in QA/QC. It takes both a good design and quality manufacturing to ensure you get a good one.

    Any TOTO bowl using 1.6 or less will clog less often than a Norris 7.0 gallon bowl from the 70's
    Funny, but true!
    With the 7.0 gallon bowls, I had a plunger by them all the time.
    Plunger sales have gone way down since people are buying better toilets.
