I forgot to say that Dick Paterson recommends always using a torque wrench when installing plugs.
Most of us just spin them in and lean on the wrench.
Dick says to torque them to 26-30 ft-lbs.
Over torque can distort the thin base and fracture the “gas tight” seals between the porcelain and metal base.
