How to Install a 100-Gal Water Tank on a Truckmount

Now that we've gathered all our tools and parts let's get to the fun part—installation!

Step 1: Position The Mounting Brackets

First, you'll want to position the mounting brackets on a stable, secure spot on your truck bed. Use your measuring tape to ensure even placement—accuracy is critical here. Make sure to measure twice and drill once. The last thing you want is a lopsided water tank!

Pro Tip: Use chalk or a temporary marker to outline where the brackets will go. This gives you a visual guide and makes adjustments easier before you start drilling.

Step 2: Secure The Tank

Now, gently place the 100-gallon tank onto the brackets. Use your wrench set to bolt it down securely. After doing this, we can't stress enough the importance of double-checking the tightness of the bolts. A loose bolt could lead to a wobbly tank, and nobody wants a water spill mid-job!

Pro Tip: Use a torque wrench if you have one. It allows you to apply a specific force, ensuring the bolts are neither loose nor tight.

Step 3: Connect The Hoses

Next, connect the water hoses to the tank. Use hose clamps to secure them tightly. A loose hose can lead to water leakage, which wastes water or professional carpet cleaning chemicals and could potentially damage your equipment.

Pro Tip: Consider using thread sealant tape around the hose connectors for an extra layer of leak protection.

Step 4: Install The Water Pump

The water pump is the heart of your water supply. Attach it to the tank and secure it with screws. Make sure it's positioned to allow easy access for future maintenance.

Pro Tip: Before screwing in the pump, make sure you've read the manufacturer's guidelines. Some pumps require rubber or silicone gaskets to prevent leaks.

Step 5: Wire It Up

Time to bring this setup to life! Strip the insulation off the electrical wires using wire strippers. Connect the wires to the water pump using electrical connectors. Make sure to follow the wiring diagram that came with your pump.

Pro Tip: Use cable ties or electrical tape to neatly bundle the wires together. This keeps your setup organized and minimizes the risk of electrical shorts.

Step 6: Test The System

After installation, it's time to put it to the test:

  1. Turn on the pump and check for any leaks or malfunctions.
  2. Make sure the pump is functioning correctly and efficiently.
  3. If everything looks good, pat yourself on the back—you're all set!

Pro Tip: Run the system for at least 10-15 minutes during the test. This allows enough time to identify any potential issues that might not be immediately obvious.

Troubleshooting Tips

Even with the best preparations, things sometimes go differently than planned. Here are some common issues you might encounter and how to troubleshoot them:

  1. Leaking Tank or Hoses: Double-check the tightness of your hose clamps and bolts if you notice any leaks. Consider applying thread sealant tape or replacing the faulty part if the issue persists.
  2. Pump Not Working: First, check the electrical connections if the water pump isn't functioning. Ensure all wires are securely connected and that there's no short-circuiting.
  3. Uneven Tank Placement: If the tank seems uneven after installation, re-measure the distance between the mounting brackets and adjust as necessary.
  4. Low Water Pressure: If you experience low pressure, inspect the water pump and hoses for clogs or obstructions. Clean or replace the parts as needed.
  5. Electrical Issues: If you're facing electrical issues, consult the wiring diagram that came with your pump. Make sure all connections match the diagram, and consider using a multimeter to check for electrical continuity.
  6. Noisy Operation: Unusual noises could indicate a loose part or an issue with the water pump. Tighten all screws and bolts, and if the noise persists, consult the manufacturer's guidelines for troubleshooting the pump.


And there you have it, folks! You've successfully installed a 100-gallon water tank on your truckmount. Remember to make sure to take all the necessary safety precautions, and then simply follow the steps we’ve outlined above.
