Cutting the Copper Hot Water Pipe – Layout A
Please follow all pre-installation instructions carefully. If further assistance is needed, a licensed and
qualified plumber in accordance with all applicable national, state, provincial, and local plumbing codes
should be hired.
1. Locate the hot water outlet connection on your pre-existing water tank. On the copper pipe, mark
with a pencil 2 inches above the topmost point of the hot water outlet connection fitting.
2. Using a pipe cutter, cut the hot water copper pipe at the 2-inch mark (Cut A), as accurately as
possible.
Refer to Figure A.
Once accomplished, unscrew the original connection fitting from the
outlet thread of the tank.
3. On the now exposed tank outlet thread, screw on the Female NPT Adapter (reference pg. 9), tightly
securing this connection.
Wrap the thread 2-3 times with Teflon Tape to seal the connection and
prevent leaks.
4. From the in-place Female NPT adapter, measure upwards
EXACTLY 11 ⅛ inches. Refer to Figure B.
Mark this on the copper pipe with a pencil.
IT IS IMPERATIVE TO BE AS ACCURATE AS POSSIBLE
DURING THIS STEP. CUTTING THE PIPE TOO MUCH WILL PREVENT A SECURE CONNECTION FROM
TAKING PLACE.
5. Cut the pipe at the 11 ⅛ inch mark (Cut B), taking extreme care for accuracy. If the installer is less
experienced or unsure, it is advised to cut the pipe slightly below the 11 ⅛ inch mark. It is safer to
cut too little and correct a mistake than to cut too much.
