Can the main pipe of residential washing machine be changed?

The main pipelines are owned by all the owners of the * * * facilities, but the developers build houses, and the houses are reported to the planning and filing through the housing construction management department.

If the owner needs to change the main pipeline for some reason, he needs to apply and report to the property management unit. After the property management unit reports to the local community street and housing management department, the main pipeline can be changed only after it is proved that there are no follow-up problems.
