So when you buy it, should you buy a spring tube or an explosion-proof tube? I suggest that you buy a better explosion-proof tube. The spring tube has a small diameter. Although it does not take up space, the pressure of the spray gun is low, and the meaning of the spray gun is lost. You can hang the position slightly higher, and the tube does not hang down. Or you can embed a ppr elbow directly above the toilet angle valve when changing the water and electricity. It is very practical to connect the spray gun or the toilet cover in the future.
