Tools Needed:

• 3/4" step-bit

• Drill

• Marker

(Optional) Flashlight to see internal wall angle

IMPORTANT INFO:

The Stem Tool is ONLY for ANTI-ROTATION. 

It is NOT a torque tool. 

 

• ✅ ALL tightening force goes into the Vent Nut using the Nut Wrench. 

• ✅ Use the Stem Tool ONLY to prevent the Vent Body from spinning — minimal torque. 

• ❌ NEVER twist or crank on the rod — it will snap. 

 

Think of it like this: The Nut Wrench is the muscle. The Stem Tool is just the spotter — there to keep things steady, not to lift the weight. 

 

Pro install sequence: Hand-tighten the nut first, then apply final torque with the wrench while gently holding the stem steady. No gorilla grips needed.

COMMON MISTAKES

MISTAKE #1: USING THE WRONG DRILL BIT

MISTAKE #1: 
USING THE WRONG DRILL BIT

A 3/4" step bit is a must.
Too big → the vent won’t seal.
Too small → the vent won’t fit.
Twist bits → tear the plastic and cause leaks.
Drilling past the 3/4" step → slightly oversized hole that won't seal

BEST PRACTICE
Use a step bit and stop exactly at 3/4". 
An oversized hole is one of the most common causes of mystery leaks.

MISTAKE #2: DRILLING IN A CURVED, THICK, OR UNEVEN AREA

MISTAKE #2: 
DRILLING IN A CURVED OR THICK AREA OF THE JUG

The internal body must sit perfectly flat on the inside wall. 

AVOID DRILLING:

• ❌ near the handle

• ❌ into a curved transition

• ❌ or into extra-thick material

• ❌raised seams, ribs or rough surfaces

 

If the inside surface isn’t flat and smooth all the way around, the flange won’t seat → leaks guaranteed.

👉 Tip: Don’t just look — reach inside and feel the landing area before drilling.

Title

MISTAKE #3: O-RING NOT SEATED CORRECTLY

MISTAKE #3: 
O-RING NOT SEATED CORRECTLY

The small o-ring on the vent body can shift when installing. If it’s: 
• ❌ crooked
• ❌ twisted
• ❌ pulled out of the groove
• ❌ contaminated with debris
…it will leak.

Always confirm the o-ring is fully seated in its groove before tightening.
If troubleshooting a leak, remove the o-ring and inspect the groove for debris or damage.

Title

MISTAKE #4: NOT DOUBLE-CHECKING YOUR HOLE LOCATION

MISTAKE #4: 
NOT DOUBLE-CHECKING YOUR HOLE LOCATION

Once you drill, there is no going back.
As Troy says: “Check, check, and check again before you drill.”

Common oversights include:
• ❌ drilling without confirming a flat interior landing
• ❌ drilling too close to the edge or radius of the tank
• ❌ leaving plastic shavings or debris under the flangeEven tiny shavings trapped under the flange can create a leak path.

BEFORE INSTALLING:
✅ Confirm the hole is exactly 3/4"
✅ Feel the inside surface for flatness
✅ Remove all debris and plastic shavings

Title

MISTAKE #5: FORGETTING TO OPEN THE VENT WHILE POURING

MISTAKE #5: 
FORGETTING TO OPEN THE VENT WHILE POURING

If you start pouring before opening the vent, 
the jug will pull suction and drain slowly.

Open the vent right after you begin pouring
to let air in and keep flow smooth.
