Is it better to use a 90 degree elbow or a 45 degree elbow for hanging urinal wall peach?

It depends on how much the size of the on-site civil engineering and decoration finish surface is left, the deeper one can do a 90-degree elbow, if the wall and the decoration finish surface is shallow, then it is natural to choose a 45-degree elbow, and in fact, the 45-degree elbow drainage and sewage flow is higher.

There are few water impurities in the wash basin, 90 degrees is OK, the key is that the water seal height is enough, and it will not return to the smell.

If there is space, it is best to use 45 degrees, or 90 degrees for a larger radius.

45 degree elbow.

90 degrees is not convenient for discharging dirt and is easy to block.

I don't know what kind of 45-degree elbow you said, if the bend is 135 degrees obtuse, then you can use it, otherwise the 45-degree acute angle, the angle is too small, increase the resistance, easy to block, and it is not easy to dredge after blocking, it is better to use 90 degrees.

If there is a certain distance between the drain pipe of the toilet and the horizontal pipe below, then this angle does not matter, if the drain pipe close to the toilet is a horizontal pipe, or 90 degrees is good, it is best to try not to store water and not reverse water.

Don't 90 degrees, 45 degrees is better. 90 degrees is not convenient for discharging dirt and is easy to block.

45 degrees is required, and now many use 90 degree elbows, the reason is that it is beautiful, trouble-free, less than an interface, and the shortcomings are not convenient for dredging sewers.

Just install a trap Why do you have so many other things.

45 degrees.

Because of the 90-degree elbow, it is easy to be clogged in use, and the 45-degree elbow is not easy to block.

When the 90-degree elbow falls into the water, the water flows vertically, which will have a certain impact on the pipe wall and produce a large noise. The pressure bearing of the elbow of 90 is poor, and if the water flow is large, it is easy to be damaged. Note that when installing the elbow, the joint between the elbow and the pipe should not be made of glass glue, and the material used to repair the pipe should be painted.

A 90-degree angle elbow is used for normal pipe corners, and only 45-degree angle elbows are used in special cases

It should be 90 degrees good. You can also choose the degree of the elbow according to the direction of the water pipe.

It mainly depends on the pipeline design, which kind of pipe is needed, which must be used, and the technical requirements are strict.

Under normal circumstances, the resistance of a 45-degree bend is greater than that of a 90-degree bend, and the head loss of each 90-degree bend is about one meter, and the resistance of every 20 meters of the pipeline can make the head loss of about 1 meter. The greater the angle of the curve, the smaller the resistance, and try to use a large angle elbow.

When the drainage pipe of the sanitary appliances is connected with the drainage horizontal branch pipe, the 90° oblique tee can be used.

Article drainage pipeline of the horizontal pipe and the horizontal pipe, the connection of the horizontal pipe and the riser, should be used 45 ° tee, 45 ° tee, 90 ° oblique tee, can also use right-angle water-following tee or right-angle water-following crosses and other accessories.

Article The connection between the drainage riser and the end of the discharge pipe should be two 45 ° elbows or 90 ° elbows with a bending radius of not less than 4 times the pipe diameter.

Article The drainage pipe should avoid axis offset, and when limited by conditions, it is advisable to connect with a B pipe or two 45° elbows.

A ninety degree elbow is easy to block, and a forty-five degree is easy to clean.

There is another reason: the water flow hits the pipe wall vertically when the elbow falls into the water, and the noise is too loud.

If the 90° elbow is used for the wall drainage pipe, it will not only cause a lot of noise in the case of a large drop and excessive water flow, but also form a great impact on the elbow if the water flow is large or mixed with foreign objects, which may lead to the rupture of the elbow part.

When using the 45° elbow, a certain slope is formed at the bend, which plays a buffering role, and even if the water flow is large and foreign matter is mixed with foreign matter when draining, the impact force on the pipe wall at the elbow will be greatly reduced.

The cleaning port is installed vertically to facilitate the removal of foreign objects at the elbow, and in case of blockage, the cleaning port can be opened directly for cleaning and unblocking.

If the water is too strong, the pipes will burst.
