The home water heater shower pipe is broken, how to change ah?

This you may not be familiar with, it is more difficult to change,

One is to take the handle off the handles, and then the tee cover off, see the tee, and then use the plate hand, or vigorously pliers clamped on the head of the connector, loosened, and replaced with a new shower pipe can be.

If you are not familiar with it, it is recommended that you find a plumber locally and spend a little money to help install it.
