Final answer:
The main water supply shutoff should be accessible for quick and safe shut off in emergencies or maintenance needs.
Step-by-step explanation:
The main water supply shutoff should be accessible.
It is important for the main water supply shutoff to be easily accessible so that it can be quickly and safely shut off in case of emergencies or maintenance needs. The shutoff valve is typically located near the water meter, usually in a basement, crawl space, or utility room.
In some cases, the main water supply shutoff may be located outdoors, usually in a pit or valve box with a removable lid. This allows utility workers or homeowners to access the shutoff valve without having to enter the building.
