Daily Pen Waterer Checks

A quick daily inspection helps catch small issues before they become bigger problems.

Check for:

• Clean, fresh water

• Debris around the nipple
• Dripping after the animal finishes drinking

If you notice water constantly dripping or reduced water flow, the nipple assembly may need to be cleaned.

How to Fix a Leaking Livestock Waterer

One of the most common questions we hear is:

“Why is my livestock waterer leaking?”

Most leaks are caused by debris inside the nipple assembly or an improperly seated O-ring.

Common Issues and Solutions

Problem	Possible Cause	Solution
Nipple drips	Debris inside nipple	Clean nipple assembly
Low water flow	Blockage	Clean tank and nipple assembly
Constant leaking	Debris or buildup	Clean nipple assembly
Poor seal	O-ring not seated correctly	Reassemble nipple properly

Before replacing parts, always clean the nipple assembly first. Many performance issues can be corrected with proper cleaning.

If cleaning does not resolve the issue, a Trojan Pen Waterer Repair Kit includes commonly replaced components to help restore proper operation.

How to Clean a Trojan Nipple Assembly

If your livestock waterer nipple is dripping or not allowing enough water flow, cleaning the internal components may restore normal operation.

Step-by-Step Nipple Cleaning

1. Remove the nipple from the elbow

Using a 7/8” wrench, remove the nipple from the elbow.

If you have a vise:

• Secure the elbow in the vise.
• Turn the nipple counterclockwise.

If you do not have a vise:

• Hold the elbow securely with a 1-1/16” wrench.
• Use a 7/8” wrench to remove the nipple.

2. Remove the internal components

Remove the gravity orifice using a large flat-head screwdriver or quarter.

Remove:

• Gravity orifice
• Spring
• Trigger
• Viton O-ring

3. Clean the nipple body

Use a small, soft brush or pipe cleaner to remove debris inside the metal nipple body.

4. Inspect the O-ring

Check the Viton O-ring for:

• Cracks
• Tears
• Wear
• Debris buildup

Clean the O-ring thoroughly and replace it if damaged.

5. Rinse all components

Make sure all soap and debris are removed from:

• O-ring
• Trigger
• Spring
• Gravity orifice

6. Reassemble the nipple

Reinstall the components in the correct order:

1. Seat the O-ring evenly inside the nipple body.
2. Insert the trigger.
3. Install the spring with the small end against the top of the trigger.
4. Reinstall the gravity orifice.

A properly seated O-ring is important for preventing leaks.

Reinstalling the Nipple Assembly

Before reinstalling:

• Inspect the nipple and elbow threads.
• Remove any debris.
• Apply thread tape if needed.

Thread the nipple into the elbow by hand first to avoid cross-threading.

Tighten securely with a 7/8” wrench while holding the elbow firmly.

Pen Waterer Maintenance Tips

For the best performance:

• Flush the nipple with clean water after use.
• Allow the unit to dry after every livestock show.
• Store indoors when not being used.
