SELECTION AND INSTALLATION

RECOMMENDATIONS FOR DRAIN SELECTION

(Models, finishes, product code identification)

Floor drain identification code 100 Roof or Terrace drains, identification code 200 Floor drains can be installed in both internal and external areas. The pipe diameter required for the drainage area is determined by the mechanical engineer’s calculations.

Carmiol drains have a collection strainer area greater than or equal to the discharge area, respecting the engineer’s design for proper water removal rate. It is recommended for exterior applications, the open area of the grate to be double the size of its discharge.

Drain location and quantity are determined according to the discharge volume, area layout and location of surrounding structures and equipment. Answer the following questions to choose the appropriate drain.

1. What is the diameter of the pipe at the installation of the drain?

Specifications of standard pipe diameters for drains can be found on the data-sheet of each product.

2. Do you prefer bronze or aluminum?

Both are high quality and anticorrosive. Aluminum is more economical while bronze offers greater mechanical resistance. In some specific cases, cast iron drain/grates are manufactured by request for heavy duty resistance.

3. Which type of fittings are preferred between the pipe and drain?

Embedded (E) (best seller), external thread, or internal thread? If the discharge pipe has a ‘male’ end attachment, then an internal thread drain should be chosen. If the attachment end is ‘female’, chose drains with an external thread. In cases where there is no pipe fitting or attachment, embedded fittings should be selected.

4. Which metal finish do you prefer?

(Non-slip, Satin, Enamel, Polished) A. Non-Slip (Ad): Economically priced and recommended for large surface areas exposed to pedestrian or vehicular traffic. Its rough surface and textured finish helps prevent accidents caused by slipping and sliding.

B. Satin (S): Our most popular finish by request. Discrete, subtle and easily matches with any floor design.

C. Enamel (Es): Utilized in places with strict attention to hygiene. The smooth surface and finish reduces health risks by minimizing the accumulation of dangerous bacteria and microorganisms.

D. Polished (P): This finish presents an attractive focal point on the floor, adding elegance to the installation area.

5. Which shape do you prefer your drain, round or square?

Many prefer square drains due to the facility to cut at right angles instead of circular cutting when installing in ceramic or tiled floors. Square drains are better suited for floors with linear designs. Round drains are also more cost effective.

6. Is the drain to be installed in places with strict hygiene regulations such as hospitals, laboratories or where food is prepared?

Indirect drains are recommended for sinks where food is washed and the discharge is not directly connected to the pipeline, but has a hose or pipe that is placed inside to allow drainage while in use. This prevents any microbes or contamination in the pipes from reaching food in the washing process. We also offer the option of enamel finish for a smoother surface and more sterile drainage. Examples of these features are drains CI-130, CI-131, CI-140, CI-141 and CI-147.

7. Do you have problems with odors and / or cockroaches coming from pipes or want to prevent these problems from occurring in the future?

We have drain designs that offer a hydraulic seal siphon which eliminates the passage of outside insects and odors from entering into the areas where the drain is installed. Examples CI- 132 , CI- 133 , CI- 134 , CI- 135 , CI- 143 and CI- 148

8. What type of traffic will the drain receive?

Pedestrian or vehicular? Drains designed for pedestrian traffic are models CI- 101 to the CI -129. The following models indicate drains designed to withstand vehicular traffic, CI- 137, CI- 140, CI- 142, CI- 149, CI- 152 and CI- 153.

9. Is your drain installation located on the ground floor, second story or mezzanine located above other floors?

Installation of a waterproof membrane layer such as asphalt or plastic is highly advised to prevent moisture from seeping through drain installations above the ground floor level. For these applications the drains are installed with a lower plate such as the CI- 144, CI- 145, CI- 146, CI- 150 and CI -151. The lower plate collects and discharges any water or moisture in between the drain and floor preventing any cause for leaking onto the downstairs ceiling.

10. Do you need an outdoor or garden drain?

We offer the CI-138 and CI-139. The dome ensures continual drainage even when the drain appears to be covered with leaves or trash. The drain’s screen is designed to prevent soil and rocks from going through the pipe.

11. Do you need a roof drain?

All 200 series drains have the necessary features for roof installations. The domes ensure that the drainage action continues even when leaves or debris accumulate at the base of the drainage. Selecting the correct model and drain will depend on the diameter of the pipe and amount of water to be evacuated. If your drain pipe is located in a corner or on the edge of the roof you can use any of our scupper drain (from CI- 211 to CI- 215) . In order to avoid water filtration problems on the floor below the roof, a waterproof membrane and drainage plate must be installed as used with models CI- 208 , CI -209 and CI- 210 .
