tagged: The Amateur Plumber’s Guide to Connecting a Typical Water Heater
Posted by GuestPoster in -Home Improvement
Water heaters need to be connected to the water supply line in the house. Steel, copper and CPVC pipes are materials that can be used for this project. (Note that PVC pipes can only be used for cold water while CPVC is for both hot- and cold-water use.) In this post, experts from plumbers Houston and plumbers Dallas teach you how to connect a typical water heater.
This procedure assumes that CPVC pipes are being used.
- Place the water heater in the spot where it will be installed. Use a level to check that all sides are even, and that the sides and front of the tank are vertically aligned to the space.
- Identify the cold water supply and the hot water feed lines on the tank.
- Install a gate valve on the cold water supply line; this provides you with a means for locally shutting off the water supply to the heater.
- Identify the cold water inlet and the hot water discharge port. The cold water inlet has a plastic tube underneath the threaded inlet; this tube is called a dip tube.
- Wrap some Teflon tape three times around the ends of each nipple. Place the Teflon tape in such a way that it thoroughly covers the threads. Thread a nipple into each port and tighten with a wrench. Use steel nipples that are at least 12 inches long for the heater’s fill and output ports to prevent heat damage to the CPVC pipe.
- Thread the bottom half of the union on top of each nipple. Tighten with a wrench as well.
- Connect the hot and cold water lines into the correct ports on the water heater tank. Measure the drop pipes needed for union installation and cut the needed lengths.
- Connect the upper portion of both unions to the correct pipes. Use a power miter box for this; a hacksaw will leave ragged ends that can damage appliance valves.
- Join the unions and secure the joining ring.
- Finally, turn on the cold water supply. Observe whether there are any leaks that need to be repaired.
