Important:
Do not over tighten ttings as this may cause leakage and broken ttings.
Do NOT use pipe dope. The use of pipe dope voids the warranty. You may
use plumber’s tape. Leave two-three threads exposed and do not exceed
seven layers of plumber’s tape. More than seven layers will cause the nipple
to crack and leak.
