Buying Guide On Floor Drain, Pop Drain, Bathroom Accessories

There are many kinds of small hardware for home improvement. How to choose and what area to install. If you have any doubts, you can understand most of them by reading this article. If you still don’t understand, please leave a message in the comment area.

Floor drain
1. Floor drain valve core
1.1U type floor drain

The principle is very simple, that is, the principle of the trap seal. The advantage is of course that it is durable, but the disadvantage is also obvious. If it is not used for a long time, the water will evaporate and it will not keep off the odor. Therefore, it can only be installed in the shower area, and if the odor control effect is to be good, the core must be made longer, so that the evaporation resistance time can be longer, but if the drain pipe is left too shallow, it will easily get stuck in the construction. The drainage speed of the floor drain is relatively slow. If the shower area is installed, it is recommended to install more than two, and the trap should be cleaned regularly.

1.2T type floor drain

The principle of T-shaped floor drain is to use spring rebound to prevent odor. This kind of drainage is faster than U-shaped, but the shortcomings are obvious. If the water is flushed frequently, the spring will age quickly. Therefore, it is recommended to install it in a dry area that is not frequently flushed, such as leak-proof water. Of course, it is not impossible to install it in the shower area, anyway, the valve core can be easily removed.

This kind of T-spool actually has an improved version now, that is, the spring is replaced by a magnet to attract and repel back and forth, which is much more durable than a spring.

1.3 Floor drain
The principle of the flap floor drain is to use a gravity block to return to its place to prevent odor. A certain boat uses this kind of plastic core. This drainage speed is not bad. The types of cores are plastic, stainless steel, and copper, and the common ones in the market are mainly plastic and stainless steel.

This kind of spool requires more workmanship, especially stainless steel. Because of the lever movable joint, it is easy to seal tightly. If the bottom drain pipe does not have a trap to prevent odor, pay attention to whether the valve core is tightly sealed.

1.4 Side sealed magnetic floor drain

Many people use this kind of spool. This kind of spool has a fast drainage speed, but it has a disadvantage that the magnets on both ends tend to attract small black spots of iron, and it is easy to seal tightly over time. However, this kind of spool is simple and cheap to clean and replace.

1.5 plastic floor drain

This kind of valve is very cheap, has good effect, and has a large displacement. The old-fashioned bowl floor drain that is not good at home can also be equipped with this valve core. Although the sealing will cause problems after a long time, this kind of cost is not high.

So I personally feel that the valve core is actually not permanent. If the seal is not good for a long time, and the drainage is not good, it will be removed and cleaned or replaced. Pay attention to the displacement and area selection. Others do not need to be too entangled.

2. Floor drain panel
There are also some tips for choosing floor drain panel types

2.1 Single use anti-reflow floor drain

This kind of floor drain can only be used to connect to the washing machine. If the bottom tube of the floor drain is left too shallow, it will easily foam and return water. This kind of floor drain can just solve this problem, but the disadvantage is obvious. If the washing machine tube is broken, the washing machine will remove the floor drain. , And there are no other floor drains, it is easy to flood the golden mountains. Therefore, it is recommended that the floor drain of the washing machine be as deep as possible. If you really want to install this kind of floor drain, you should consider leaving a secondary floor drain to prevent it.

2.2 Dual purpose floor drain

As the name suggests, this kind of floor drain can be used to collect water or take over. It is generally used to connect the washing machine pipe and plug the water pipe under the wash basin.

2.3 Single use ordinary floor drain

This kind of floor drain is often used in shower rooms.

2.4 Hidden floor drain

This floor drain panel can be turned over, cut into bricks and embedded in it, and it is beautifully finished.

I don’t recommend installing this kind of 10X10 hidden floor drain in the shower room, because the water collection area is relatively small and the drainage speed will be slower. Longer ones will collect water faster, such as 30X10 or more. However, there are very few copper products above 30X10, and the price is very touching if there are some. There are many stainless steel products. And it is recommended to install an auxiliary floor drain, such as a triangular hidden floor drain, the drainage speed and beauty are leveraged. Of course, this kind of long floor drain also has a double floor drain valve core:

2.5 bowl old fashioned floor drain

This kind of water trap, which is usually a few dollars, is very shallow, and has poor water resistance, odor resistance, and poor drainage. Now home improvement is rarely used.

3. Floor drain material

3.1 Copper plating

Copper floor drains are generally more expensive, and the plating layer of floor drains that can pass a 24-hour salt spray test will be more durable.

3.2 Stainless steel

Stainless steel is divided into 201, 202, and 304, and household 304 is more, but 304 is also divided into 304 and miscellaneous materials 304.

As we all know, more impurities are more likely to form a galvanic effect corrosion surface layer. And even if it is 304, sometimes the surface passivation film will be damaged and it will cause floating rust, but it will disappear after rubbing.

The process of stainless steel is divided into stamping and precision casting.

Stamping is cheaper, but the workmanship is not so good, and there will be seams in some places. Take the hidden floor drain as an example, the sides will be thicker, and the panel will have seams. See the picture below:

Precision casting is very expensive, but the details are much better. The sides will be narrower:

3.3 Zinc alloy

This is generally worse, so I won’t expand on it here.

As for the panel color, choose it according to your decoration style.

in conclusion:

Shower area:

If you want to look good, you can consider hiding the floor drain, but remember to choose a longer one to collect water faster. If you can, use a double concealed floor drain to drain faster. If you want to keep things simple, just use the floor drain alone. The spool should be durable and choose the U type, but the U type is recommended to be equipped with a double floor drain, because the U type has a slower drainage. To drain water quickly, use side seal magnets and silica gel. If the sewer pipe is too shallow, use gravity flaps. The T type is also less durable than the former.


If the wash basin is used for wall drainage, it should look good. It is enough to install a hidden floor drain to prevent water leakage. It is cheaper to install an ordinary single-use floor drain. The valve core should be T-shaped.

If the wash basin is drained from the ground, install a dual-purpose floor drain. Considering that the wash basin often drains water, if you want to be durable, you can choose a magnetic floor drain T type. If you want to drain, use side seal magnetic suction, silica gel, and T type can also be used. , But the durability is not as good as the first two.

Washing machine floor drain:

It is recommended to leave the water pipe directly inserted in the washing machine tube, and then make a T-shaped leak-proof next door. Of course, you can also use a dual-purpose floor drain, but the bottom should not be too shallow, otherwise it will easily bubble back. If the tube is too shallow, you can Consider installing an anti-reflow floor drain. The valve core is generally side-sealed or silica gel, and the drainage should be faster.

Floor drain purchase is one aspect, the pipe diameter should be more than 50, pipe depth, leveling, retaining slope, retaining water bend (above the national standard 5cm water seal!) and other construction details need to be paid attention to.

There are two main types of sink drains: flap and bounce.

It is said that the flap is durable, but the pitfall is that the water often rushes to the flap, and the flap is closed. As a result, we have to manually open the flap after brushing our teeth and wait for the water to dry before flushing the foam with water, which is a waste of time.

If you press the bounce frequently, it will age more severely. In fact, we usually use the basin to seldom turn off the water and sewage (unless you use the basin to soak clothes, but it feels dirty, and occasionally wash one or two clothes by hand is also a plastic bucket). So just buy a bounce, use running water, and keep it normally open.

It is recommended to buy this:

Large cover, easy to press, split design, easy to replace and install, with basket, easy to clean foreign objects.

There is a kind of drain that looks very thick on the market, but it is recommended to buy it carefully. This kind of drain is made of alloy and is very easy to crack.

This is recommended for ground drainage
Some of the anti-odor cores inside are flip-flops, which drain quickly and will not block: If it is wall drainage, you can consider installing the following two for aesthetics, especially hanging basins:
However, the height of the above two types must be determined when leaving the nozzle, especially the second type of water separator, the center point must also be determined, otherwise it will not be used if it is installed low, and it will easily leak if it is installed. There is another problem. The water separator is recommended to be installed in a small pot, because the drainage speed is average.

In addition, it is best to buy this kind of sewer pipe carefully on the market.
This kind of sewer pipe is water-sealed, it is easy to be blocked, it is troublesome to clean up, and it is easy to leak, which is very cheating!

Finally, I often see people saying that water leaks under the drain and the inside of the cabinet is wet. In fact, it is very simple. One is that your basin mouth is too rough, and the other is leaking from the overflow to the nut connection below, so it is very simple and rough. Use an angle grinder to polish it or use glue to smooth it, and then tie more raw material tape or glue to the bottom of the nut joint. It is recommended to use an angle grinder + raw material tape. It is better to remove it later.

Bathroom accessories
For pendants, consider choosing space aluminum, which is cheap and easy to use. Why do you say that?

Firstly, the space aluminum pendant is cheap, and secondly, the surface of the space aluminum pendant is matte, and the bathroom is relatively wet. If the water vapor is liquefied on the surface, it will not be stained and dirty like a bright electroplated layer after it dries. It is easy to damage the plating layer after rubbing for a long time.

Also, don’t choose basket-shaped racks. Shampoo and shower gel are not stable and easy to fall off. Buying a board is also very stable.
Don’t buy a folded towel rack, because most people don’t fold it up.

However, due to the material of space aluminum, it cannot be made too many shapes, and the style will be relatively simple. The same is true for stainless steel.

Of course, if you have a lot of money, you can also buy full copper plating, but the price is too touching, but be careful not to buy zinc alloy plating, the quality is very poor.

One thing to point out is that space aluminum can’t be used in the kitchen, because the oil is heavy and it is not easy to clean. Stainless steel pendants are more suitable for the kitchen environment.
