<human>:  I need help with plumbing. Which pipes should I use for running a hot water supply for a new kitchen sink?
<bot>: The best pipes to use for running a hot water supply for a new kitchen sink would be copper pipes. Copper pipes are the most reliable and are more heat resistant than other types of pipe material. They also provide good insulation so that your hot water remains at a consistent temperature. Additionally, copper pipes are more expensive than other types of pipes, but they will provide a more secure and longer lasting hot water supply.
