Bathroom drainage can not be separated from the floor drain

First, what material is good for the floor drain

 

All copper chromium-plated floor drain: the most on the market today is all copper chromium-plated floor drain, all copper chromium-plated floor drain coating thick, so even if the use of a long time, long copper rust, but it is easier than cleaning. The service life of all copper chrome-plated floor drain can be used for at least 6 years, and the performance is relatively good, so it gradually occupies an increasing market share in the market.

Stainless steel floor drain: Although the stainless steel floor drain looks beautiful, the odor prevention effect is good, and the service life is long, the cost of the stainless steel floor drain is higher than that of the PVC floor drain, and the coating is relatively thin, so it is easy to rust after a few years, and the stainless steel floor drain is not good with the tile.

PVC floor drain: PVC floor drain price is relatively cheap, deodorant effect is good, but easy to aging, the material is relatively brittle, in the cold north, it will not take long to replace, so the market is not very optimistic.

Zinc alloy floor drain: although the corrosion resistance is strong, the price is cheap, but the service life is particularly short, Xiaobian recommends not to buy.

Ceramic environmental protection material floor drain: good performance, and the matching of ceramic tile floor is of course not suitable, but most of the current customized products, the price is expensive.

 

Second, what's good about the floor drain

 

Water-sealed floor drain: Water-sealed floor drain has the longest history, its biggest defect is that if not used for a few days, the water trap because of no water storage and the smell of the sewer pipe and pests drive straight into, even if some manufacturers will increase the water trap, but there will be a longer business trip or a long time without use and not deodorant problem, but also produce another problem, the higher the water seal, the easier it is to hide dirt in the core. These dirty things are difficult to clean up, and because the floor drain itself is domestic sewage, so the water stored in the south or summer water trap will stink in a few days, forming a new source of pollution.

Mechanical (gravity) : Using the balance principle of water pressure and counterweight block, automatically adjust the size and opening and closing of the gasket opening and closing, the water is immediately closed, will not give odor, pests any opportunity, fully use the water's own gravity to open and close the sealing cover plate, infinite speed regulation, natural and smooth, without water seal, without the use of springs, magnets and other external forces, reverse the use of gravity principle to open and close the gasket. At present, this kind of floor drain has no obvious shortcomings, but if the mechanical floor drain is unqualified, it will cause a complete failure to prevent odor.

Spring type: divided into up and down bomb type. The upshot type is to press the cover plate, the cover plate springs up, and when pressed again, it will reset; The lower elastic type is sealed by stretching the gasket at the lower end of the sealing core with a spring.

Disadvantages: Because the spring is made of iron boron, easy to rust, elasticity gradually weakened, until failure, life is not long, and the spring is easy to wrap hair, fabric, not easy to clean.

 

Third, floor drain size selection

 

Deodorant drain size is mainly 3 inches and 4 inches diameter two more common, there are other sizes, from small to large, the size is many. According to the shape of the deodorant drain, there are square, round, rectangular, etc., the size of the household square deodorant drain is from 90mm*90mm to 150mm*150mm, and the material is brass, white copper, bronze, stainless steel, plastic, alloy, cast iron and so on.

Before buying odor-proof floor drain, you should have a basic understanding of the size of the sewer pipe in your home, if it is the national standard size, you can rest assured to buy the corresponding standard size of the odor-proof floor drain, if it is non-national standard, you must specifically measure or understand the size of the sewer pipe in advance, and then choose the size of the odor-proof floor drain accordingly, so as not to install or inappropriate. It doesn't work as a floor drain. The floor drain sold on the market is the standard size, consumers in the purchase is more trouble, if the size is not compatible, but also need to decorate workers to rework, so the best way is the consumer first do not let the decoration workers modify the size of the drainage hole, go to the market first to select the appropriate floor drain, and then let the decoration workers according to the size of the floor drain to repair the drainage hole.

The aperture of the floor drain grate is best in 6-8mm, if it is greater than this aperture, it is easy to let hair, sludge and other things from the floor drain into the sewer, causing sewer blockage and causing trouble.

 

Fourth, floor drain installation method

 

The first step, before the floor drain is replaced, the cement near the floor drain is removed with a screw, and then the floor drain is struck with a small hammer to separate the floor drain from the cement below for easy removal.

The second step, knock down the old floor drain, the floor drain on the market is basically water sealed floor drain, its water seal is very shallow, the base can not achieve the effect of deodorization.

The third step, use a chisel to finish the cement layer near the drain pit. Pay attention to the drainage pipe must be temporarily plugged up, do not let debris fall into the drainage pipe.

The fourth step, after cleaning, scrape the cement putty near the pit wall.

The fifth step is to scrape the cement putty near the floor drain to make it firmly connected with the ground.

The sixth step, the center of the floor drain against the middle of the drain pipe, into the original position of the floor drain, according to the solid, the horizontal plane of the floor drain should be slightly lower than the tile surface.
