What you should know before installing a bathroom floor drain

Before installing a floor drain, prepare the sewage system for it. If you plan to use a pressurized water line, you must install a trap primer, a small water line that connects a floor drain to a pressurized water pipe. The angle of fall must remain constant, about 1/4 inch per linear foot. Afterward, tile the floor area. Once the sewage system is ready, you can install a bathroom floor drain.

Cleaning the floor and work area before installing a bathroom floor drain

Before you begin installing a bathroom floor drain by IPS Corporation, make sure to clean the floor and work area thoroughly. It is necessary because floor drains can collect debris and dirt. It would help if you swept the floor regularly to avoid worrying about clogged drains. Moreover, it would be best to clean the drain regularly when you are experiencing clogging. Using a high-pressure water jet can also help to remove stuck debris.

Trap primers are a valve and a small water line that link pressurized water pipes to floor drains

While the floor drain is a relatively simple feature, traps can be difficult to maintain. It is why the introduction of trap primers became necessary. These devices help prevent sewer gas leaks in bathrooms and release foul odors. In many cases, they are even required by local building departments. A good place to buy bathroom floor drains is from a building supplier like Romtec, and they can design, supply, and install the bathroom facilities you need.

The simplest of trap-priming systems is the single-piece design. The valve and small water line are installed in the sink and extend to the p-trap on the floor drain. The valve is schematically represented as a cartridge in a water pipe. 

Trap seal primers can be pressure-drop activated or electronically operated. Trap seal primers must be installed on a one-half-inch male iron pipe. The trap is activated when the pressure in the line drops three psi. When this pressure difference occurs, the trap seal is opened, and water flows under pressure into the floor drain trap.

Tiling a bathroom floor drain

When tiling a bathroom floor drain, you must carefully pay attention to the floor drain’s location and tile around it. It should not be too close to the drain since pooled water will cause problems, like mold growing between the gaps. The tiles around the drain should be at least a quarter-inch apart. To avoid unnecessary mistakes, you should follow the steps below to install the drain and tile around it properly.

Alternatively, you can trace the drain shape on cardboard and cut it out. After marking the exact location, use a thinset mortar to cover a few square feet of the floor. Start by applying the thinset mortar and tiling the tiles in the space between the lines. Once you have covered the area, you can place the full tiles over the drain. The tiles must be positioned over the drain.

For an even finish, level the floor before you begin tiling. The slope of the bathroom floor should slope inwards about 2%. You should lay the tiles level or one mm above the tile frame when tiling a shower. It would be best if you also ensured that the tiles slope toward the drain. 

Preparing the sewage system for a floor drain

To install a bathroom floor drain, you must ensure that the mainline sewage pipe is properly prepared. This pipe is typically 4 inches in diameter. It can be made of ABS plastic or PVC plastic; some are made of clay or cast iron. The piping system runs underneath the basement or the foundation slab, and it is often hidden and is only exposed during major repairs and additions. 

Choosing a floor drain type

Linear – The linear drain is a long steel channel fitted between the shower walls. This type is usually framed and covered in ceramic tile. Linear drains are also available in plastic and can be molded into different shapes. These types of bathroom floor drains are generally cheaper than other types of drains. You may also want to use a linear drain in a child’s bathroom.

Bathtub – The shower type should match the type of floor beneath. If you choose a tub drain, make sure it has a lift-and-turn mechanism. These mechanisms are typically operated by turning a counterclockwise lever, which can be either one-piece or two-piece. Depending on the floor style, one-piece or two-piece showers will require different drains.
