Frequently Asked Questions
What type of fittings to use on a water heater?
Common fittings for water heaters include threaded brass or stainless steel connectors, compression fittings, and dielectric unions. Dielectric unions prevent corrosion between dissimilar metals, extending the system's lifespan. Flexible stainless steel fittings are often used for easier installation and maintenance. Always choose fittings that match your water heater's specifications.
Do heat trap nipples restrict water flow?
Heat trap nipples are designed to minimize heat loss from the water heater but can slightly restrict water flow. This reduction is typically minimal and doesn’t impact overall performance. They improve energy efficiency by preventing heat from escaping through the inlet and outlet pipes, making them a worthwhile addition.
What size are the fittings on top of a water heater?
Fittings on top of a standard water heater are typically 3/4-inch in diameter, matching most water supply lines. These standard sizes ensure compatibility with common plumbing systems. Always verify the manufacturer’s specifications for your model before purchasing or installing fittings.
