Which of the following is NOT a typical component of a service tap?

A service tap typically refers to the point where a water supply line connects to the main distribution system to provide water service to a customer. The components involved in a service tap generally include a water meter, a curb stop, and the piping that connects to the customer's plumbing system, such as copper tubing.

The meter is essential as it measures the amount of water consumed, which is used for billing purposes. The curb stop is a shut-off valve that allows the water supplier to control the water flow into the customer’s property and is usually located near the property line. Copper tubing is commonly used for its durability and resistance to corrosion in the water supply piping.

A pressure tank, however, is not a typical component of a service tap. Pressure tanks are used to maintain water pressure in a plumbing system and are generally found in well systems or water storage systems where pressurization is needed, rather than being part of a service tap connection to a water supply network. Therefore, the correct answer identifies the component that does not belong in the context of what is included in a standard service tap setup.
