    We just purchased a home recently which has wall mount toilets, approx 40yrs old. One is an American Standard with a 4049 tank, gravity flow. The tank cracked and flooded the bathroom. I’m looking for a replacement tank but only find the pressure assist for that model. Will the pressure assist work on the older model toilet or is that what they were originally built with?
    Thanks in advance.

    For the old bowl, you need something that flushes five gallons. The pressure assist only does 1.6 gallons.
    You either need an old tank for that, or just replace the tank and bowl. Gerber makes a nice replacement that fits on the same bolt pattern.

    The bowl is about 1.5" higher and uses 1.28 gallons. It comes with a compact elongated bowl.

    Really appreciate the quick response. Here are a couple pictures. It looks different than the AS placed in my original post. Did the previous owner just install the wrong bowl or flapper, or remove the pressure assist? It seemed to work fine and use less gallons than the other one in the house. (Tan toilet) which definitely uses a lot of gallons and flushes horribly.

    Pressure assist will not work with your old bowl.
    Don't waste your time trying. The bowl on your forty year old water wasting bowl was never designed to flush with only 1.6 gallons and even worse, not with a pressure assist which needs a bowl designed for that type of action. It's a totally different way of moving water through the bowl. The old bowl used at least 3.5 gallons to siphon the bowl. Pressure assist pushes water out of the bowl, and with just a little bit. With the old bowls, it won't evacuate the water from the bowl. It just kind of stirs your pee and poo a bit. Not good.

    Here they are explaining how the design of the bowl needs to be matched to the tank.

    What you had was a large volume gravity bowl that "slowly" moved water through a trapway. A lot of water was needed.
    1.6 gallons will only stir the water a little bit, but not create the siphon it needs.

    So many ways to design a bowl. They are not all the same. Not at all.

    The bowl in front is a Kohler pressure assist.

    The toilet is an old Kohler wall hung, using 3.5 gallons to flush with. They were pretty popular in the 60's.

    Finally just received my Gerber Maxwell after two months on order. Not a big deal but definitely much longer than expected.
    Anyhow, just pulled the old toilet to realize the previous owner built his own toilet mount. Angle iron bolted to studs.
    Dimensions seem to work, just hope it seals. No wonder plumbers can’t stand do-it-yourselfers. At least do it right if there doing it themselves! Thanks, we’ll see what happens.

    Well, it’s installed. Only time will tell if it holds up and doesn’t leak. Thanks for the help.

    I have a American standard Wall Mount Model F4040 with a cracked tank as well. I found a used 4049 tank on e-bay. Does anyone know if that will fit. I would rather replace just the tank. If not I will follow the Gerber Maxwell Replacement.
