X-Jet (M5 Nozzle): Long-Range Chemical Application Guide

Key Takeaways

• X-Jet applies chemicals 30-40 feet - Without ladders or lift equipment
• M5 nozzle color codes mix ratio - Red, yellow, green, white, black tips
• Downstream injection built-in - Draw chemical through venturi effect
• Not for surface cleaning - Chemical application only, then rinse
• Technique matters - Proper distance, angle, and coverage critical

What is an X-Jet?

The Concept

X-Jet = Long-Range Chemical Applicator

It’s a specialized nozzle system that allows you to apply cleaning chemicals from 30-40 feet away. Instead of running hoses up ladders or using lifts, you can apply chemicals from the ground safely and efficiently.

How It Works:

1. M5 nozzle - Special tip creates venturi effect
2. Draws chemical - From container through siphon hose
3. Applies at distance - Sprays 30-40 feet accurately
4. Color-coded tips - Control mix ratio (strength)
5. Rinse with different tip - Switch to rinse after application

The “X” Pattern: When spraying, the X-Jet creates an “X” pattern of chemical coverage. This provides even coverage without the need to get close to the surface.

X-Jet vs Downstream Injector

Downstream Injector:

• Closer range - 15-25 feet max effective
• Fixed mix ratio - Usually preset by injector
• Through gun/wand - Chemical enters after pump
• Standard equipment - Most setups have this

X-Jet:

• Longer range - 30-40 feet effective
• Variable mix ratio - Change tips to adjust strength
• Dedicated tool - Separate from gun/wand
• Specialized equipment - Add-on for specific use

When to Use Each:

• Downstream injector - Most house washing, standard distances
• X-Jet - Second/third story work, hard-to-reach areas, large buildings

Complementary Tools: Many professionals have both. Use downstream injector for most work, X-Jet for high or difficult areas.

X-Jet Components

The M5 Nozzle

What It Is: Special nozzle tip that creates the venturi effect needed to draw chemicals. The “M5” refers to the orifice size and design.

Characteristics:

• 1/4” quick-connect - Attaches to your gun/wand
• Color-coded tips - Thread into M5 nozzle
• Precision machined - Consistent performance
• Brass construction - Durable

How It Works: Water flows through the M5 nozzle at high velocity, creating a vacuum that siphons chemical up through the delivery hose and mixes it with the water stream.

Proportioning Tips

Color-Coded Mix Ratios:

Red Tip (Strongest Mix):

• Ratio: ~1:1 (chemical:water)
• Use for: Heavy algae, black streaks, stubborn growth
• Most concentrated application

Yellow Tip:

• Ratio: ~1:4
• Use for: Moderate growth, typical house washing
• Most common ratio

Green Tip:

• Ratio: ~1:8
• Use for: Light growth, maintenance cleaning
• Gentler application

White Tip:

• Ratio: ~1:15
• Use for: Very light cleaning, delicate surfaces
• Weakest application

Black Tip (Rinse):

• No chemical - Clear water only
• Use for: Rinsing after chemical application
• Essential step

Chemical Delivery Hose

What It Is: Flexible hose (usually 3/8” ID) that siphons chemical from container to the M5 nozzle.

Characteristics:

• 10-20 feet long - Reaches from your container to nozzle
• Chemical-resistant - Handles SH and acids
• Weighted strainer - Filter on end (keeps debris out)
• Barbed fitting - Attaches to container

Important Notes:

• Always use strainer - Debris clogs nozzle
• Keep hose short - Longer = harder to draw
• Elevate container - If possible (affects siphoning)
• Inspect regularly - For cracks and wear

Using the X-Jet

Setup and Connection

Assembly:

1. Connect M5 nozzle - To your gun or wand (quick-connect)
2. Attach proportioning tip - Choose correct color for mix ratio
3. Connect chemical hose - To barbed fitting on M5 nozzle
4. Place strainer end - In chemical container
5. Test siphon - Should draw chemical when triggered

Pre-Job Checks:

• Container positioned - Within reach and hose length
• Chemical mixed - Proper ratio and strength
• Strainer clean - Not clogged
• All connections tight - Prevent air leaks
• Test spray - Verify chemical is drawing

Application Technique

Distance and Angle:

Optimal Distance:

• 30-40 feet - Design range for X-Jet
• Start closer - 25 feet, move back as needed
• Test pattern - Verify coverage before full application
• Maintain consistent - Distance affects coverage

Spray Angle:

• 45 degrees to surface - Optimal for most applications
• Adjust for wind - Steeper angle if windy
• Never straight-on - Reduces coverage effectiveness

Coverage Pattern:

Technique:

1. Start at bottom - Work upward
2. Spray in X pattern - Natural nozzle pattern
3. Overlap sections - By 6-12 inches
4. Maintain distance - Consistent coverage
5. Work systematically - Don’t jump around

Coverage:

• Side to side - 4-6 foot wide path per position
• Multiple passes - For full coverage
• Overlap passes - Prevent missed areas
• Even coverage - Critical for effective cleaning

Chemical Application

Proper Order:

1. Apply chemical - Using appropriate tip (usually yellow or green)
2. Allow to dwell - 5-15 minutes depending on chemical and surface
3. Rinse thoroughly - Using black tip or regular nozzle
4. Inspect results - Reapply if needed
5. Final rinse - Ensure all chemical is removed

Don’t:

• Apply too heavy - Wastes chemical, can damage
• Skip dwell time - Chemical needs time to work
• Forget to rinse - Leaves residue, can damage surfaces
• Rinse too soon - Wasted effort and chemical

Mix Ratios and Strength

Understanding the Ratios

What Ratio Means: Ratio refers to parts of chemical to parts of water after mixing.

Example:

• 1:4 ratio - 1 part chemical to 4 parts water
• If container has: 1 gallon chemical + 3 gallons water = 4 gallons total
• Strength: ~20% concentration (stronger than downstream injector)

Why Stronger Than Downstream: Downstream injectors typically dilute 10:1 to 15:1. X-Jet ratios are much stronger, which is why it’s effective at distance.

Choosing the Right Tip

Red Tip (1:1) - Heavy Growth:

• Use for: Heavy algae, thick black streaks, significant growth
• Surfaces: Concrete, brick, durable materials
• Caution: Very strong, test small area first

Yellow Tip (1:4) - Standard:

• Use for: Typical house washing, moderate algae
• Surfaces: Most siding, concrete, masonry
• Most common: Default choice for most work

Green Tip (1:8) - Light:

• Use for: Light growth, maintenance cleaning
• Surfaces: Delicate areas, previously cleaned surfaces
• Less damage risk: Gentler on plants and surfaces

White Tip (1:15) - Very Light:

• Use for: Very light cleaning, sensitive areas
• Surfaces: Delicate materials, first-time cleaning uncertain surfaces
• Safe choice: When you’re unsure about surface sensitivity

Black Tip - Rinse:

• Use for: Rinsing after chemical application
• No chemical: Clear water only
• Always: Final step before moving to next area

Bottom Line

X-Jet is a specialized tool for specific applications: high work, large areas, or difficult access. It’s not a replacement for downstream injector—it’s a complement to it.

For professionals: Essential equipment. You’ll use it on almost every house washing job for second story work, and it opens up commercial work you couldn’t do safely otherwise.

For homeowners: Probably not worth it unless you have a multi-story home and plan to do your own cleaning regularly. For occasional use, hiring a pro is likely more cost-effective.

Technique matters: The X-Jet is only as effective as your technique. Practice your distance, angle, and coverage. Bad technique = bad results regardless of equipment quality.
