The drain pipe stores water, and the ball test is how to do it

1. Put the small ball of the size of the drainage pipe diameter 2 3 into the end of the main drainage riser and the horizontal sensory pipe.

2. Then discharge the water to flush the ball down with the drainage pipe, open the mouth left in the lower layer, if the ball can pass normally to the end of the lower drainage pipe, it is qualified, if it cannot pass, it is unqualified. The pass rate must be 100% passable.

Code for Acceptance of Construction Quality of Building Water Supply and Drainage and Heating Engineering "GB 50242-2002", the main indoor drainage riser and the main pipe of water should be tested through the ball, and the ball diameter is not less than 2 3 of the diameter of the drainage pipe, and the ball rate must reach 100%. Based on the investigation of common diseases in the quality of drainage projects, he ensures that the quality of the project requires that the drainage riser and horizontal main pipe should be tested through the ball; 100% of the ball must be guaranteed; The ball diameter should not be less than 2 3 of the diameter of the drainage pipe. Outdoor drainage pipes do not do through-ball test.

Put the small ball of the size of the drainage pipe diameter 2 3 into one end of the main drainage riser and the horizontal sensory pipe, and then discharge the water to flush the small ball down with the drainage pipe, and open the mouth left in the lower layer, if the small ball can pass normally to reach the end of the lower drainage pipe, it is qualified, if it cannot be passed, it is unqualified. The pass rate must be 100% passable.

Pass the water first, then pass the ball. The irrigation test is only required to be done with concealed pipes, and if there is no concealment, there is no need to do the irrigation test.

The irrigation test is that the indoor hidden or buried drainage pipe needs to be filled with a water test to see if there is leakage, if there is leakage must be treated before concealment or burial, if there is leakage after concealment, it is very troublesome to deal with it.

The ball test is to check whether the pipeline is blocked, which is suitable for horizontal main pipes or main risers, and needs to be checked by the ball test, if there is a large blockage, the ball cannot be passed.

The water test is carried out after the installation of the drainage system, and the whole system is connected to see if it is smooth and whether there is leakage. Do the final check.

Hello, bathroom drainage to do through-ball test' method: put the small ball of the size of the drainage pipe diameter 2 3 into one end of the main drainage riser and the horizontal sensory pipe, and then release the water to flush the ball down with the drainage pipe, and open the mouth left in the lower layer, if the ball can pass normally to the end of the lower drainage pipe, it is qualified, if it cannot pass, it is unqualified. The pass rate must be 100% passable.

Purpose: The through-ball test is to test the anti-clogging ability of building pipes. If the ball is blocked, the ball can be pulled out, the length of the line can be measured, then the blocked part can be judged, and then the dredging treatment is carried out, and the ball test is repeated until the pipeline is unobstructed, if the transverse pipe section behind the elbow of the outlet pipe is longer, the ball is not easy to roll out, and some water can be poured to help the ball flow out.

The through-ball test must be 100% qualified before the drain pipe can be put into use.

Put the small ball of the size of the drainage pipe diameter 2 3 into the main drainage riser and one end of the horizontal sense collapse of the Shenguan pipe, and then release the water to flush the ball down with the drainage pipe, and open the mouth left in the lower layer, if the ball can pass normally to the end of the lower drainage pipe, it is qualified, if it cannot pass, it is unqualified. The pass rate must be 100% passable.

Purpose: The through-ball test is to test the anti-clogging ability of building pipes.

If the ball is blocked, the ball can be pulled out, the length of the line can be measured, the blocked part can be judged, and then the dredging treatment is carried out, and the ball test group is leaked repeatedly until the pipeline is unobstructed, if the transverse pipe section behind the elbow of the outlet pipe is longer, the ball is not easy to roll out, and some water can be poured to help the ball flow out. The through-ball test must be 100% qualified before the drain pipe can be put into use.

What are the steps of the water supply and drainage test and the ball test?

Dear, I will answer for you, <>

Excuse me, what are the steps of the water supply and drainage project water supply test and the ball test? Answer: The steps of the water test are as follows:

Check all valves of the water supply system, close all the water distribution valves, and open all the control valves. The water supply system is supplied with water at the same pressure and water quality as the design requirements, and the hot vertical round water system is supplied with cold water at the same pressure as the cold water.

The position of the inspection mouth is on the drawings, the ball test is done after the drainage project is completed, the test ball is a plastic ball, the ball is put into the toilet hole on the top floor and flushed with water, and the ball can be observed in the manhole on the ground to see if it can come out, generally only do the top ball test, but each toilet must be done once.

Note that if the ball is blocked, the ball can be pulled out, the length of the line can be measured, the blocked part can be judged, and then dredge the treatment, repeatedly do the ball test, until the pipeline is unobstructed, if the transverse pipe section behind the elbow of the outlet pipe is longer, the ball is not easy to roll out, you can pour some water to help the ball flow out. The through-ball test must be 100% qualified before the drain pipe can be put into use.

Just put a little bit of a ball on it.
