    Tips Of Flange Installation

    Should toilet flange be flush with floor? Yes, you can also say the floor should be set so that it is flush with the flange.

    A faulty installation can lead to significant water damage. Here are some notes on the factors that you should consider when installing such a fixture:

    • Capacity (weight) carrying capacity should correspond with what you choose as your method of installation; support base, bolts, and screws, bolts only, weight-bearing bolts, etc.
    • Pipe should be at least one size larger, but not more than two sizes more significant, than the closet flange outlet. The ideal diameter is 1-1/2 inches for standard toilets and 2 inches for comfortable toilets.
    • If possible, do not overlap the pipe by turning it 180 degrees between flanges. This should only be done when necessary to avoid cutting or threading into tile or marble that may break.
    • Do not use thinner-walled piping than recommended by the manufacturer of your toilet. You should use the thicker piping where there are obstructions in the flow path. Structural elements such as joists or beams need to be crossed en route from source to destination.
    • Do not use extensions (longer length of pipe) with the toilet flange. This should be done only when necessary to complete the installation. However, if you do use an extension, ensure that the original piping is cut and capped off. A new drainage line is installed between these points: 1/2″ beyond the wall and 1/4″ beyond the thicker-walled piping or any obstruction along its path.

    What Should Be The Distance Between The Toilet Flange And The Floor?

    As per industry standards, the toilet should sit within 1/4 inch of height difference (one way or the other)of closet flange and finished floor. This should not be less than 1-1/2 inches under normal conditions. However, this should not be less than 2 inches for comfort height toilets. Only installing the flange at a proper height can make sure its drainage, like the rough-in height for bathroom sink.

    Problems with having a gap between the bottom of the toilet and the top of the flange:

    -If there is too much gap at the base of your toilet, water will begin to pool underneath your bathroom’s tiles or flooring. This can lead to seepage problems in adjacent areas. It also represents wasted water, making it more expensive to run your toilet. And should the flange fail, this could lead to further damage should water leak into surrounding areas.

    -If there is too little gap between the toilet and flange, your bathroom may be subjected to drainage issues should your main drain line develop a leak one day.

    Should Toilet Flange Be Flush With Floor?

    A toilet flange should be flush with the floor. When a toilet could not flush, for example, if it has a low water level or no water in the bowl, there should be a minimum gap between the bottom of the toilet and the top of the flange (toilet flange).

    There are two types of toilets: regular (standard) height and comfort height. An accessible fixture is one whose height sits between different ranges to allow easy use by people who may have trouble bending or stooping too low while using it. This includes people like older adults, some pregnant women, some children, and some individuals with disabilities. Comfort height can also be called ADA height.

    Some states permit the installation of an accessible toilet with a height of 14-1/2 to 15 inches from the floor to the top of the seat. You should note that there is no federal standard for a particular maximum height. Still, a toilet should not usually require a significant amount of additional hip and knee flexion during use.

    1. Leave the gap where the toilet flange does not sit flush with the finished surface (tile or marble) one way or another upon installation. The best method for adequately setting your toilet is by using large-diameter washers on the underside of tank bolts and nuts on bottoms of closet flange bolts to prevent loosening due to vibration.

    2. If there is too much gap at the base of your bathroom’s tiles or flooring, it can lead to seepage problems in adjacent areas. This can also represent wasted water, making it more expensive for you to run your toilet. If the flange should fail, this could lead to further damage should water leak into surrounding areas.

When the flange should not be flush with the floor, you are experiencing problems with seepage through underlayment or tiles in adjacent areas due to a lack of space between the floor and top of the flange. The solution should, as stated previously, include adjusting as needed by either adding or removing washers on underside tank bolts and nuts on the bottom of closet flange bolts; proper adjustments should resolve any issues associated with deviation from industry standards.

    The best way to ensure the toilet is by using large-diameter washers on the underside of tank bolts and nuts on bottoms of closet flange bolts to prevent loosening due to vibration.
