Tools And Items You'll Need:


  • Why You Need It: To seal the unused vacuum inlet port.
  • Where to Get It: Any big-box hardware store will have these in the plumbing section.

Tachometer (Optional)

  • Why You Need It: To check the engine speed and ensure optimal vacuum performance.

Steps To Seal A Vacuum Inlet

Step 1: Identify The Ports

Locate the vacuum inlet ports on your truckmount. These ports are usually situated near the back of the machine and are essential for vacuum suction. Knowing the size of your ports—whether they are 2-inch or 2.5-inch—will guide you in purchasing the correct PVC cap size. The wrong size cap will not provide an effective seal.

Pro tip: Take a measuring tape with you when you go to purchase the PVC cap. This ensures you get the right size the first time, saving you a return trip to the store.

Step 2: Choose Your Configuration

Decide if you'll be using a single port or dual ports. This decision is based on your specific cleaning needs and the capabilities of your truckmount. Using dual ports can maximize vacuum efficiency, allowing for quicker and more effective cleaning. 

However, a single port is often sufficient for most jobs and is easier to manage.If you're unsure about which configuration to use, consult your truckmount's manual. It often contains recommendations on optimizing vacuum efficiency.

Step 3: Seal With PVC Cap

If you opt for a single-port configuration, place a PVC cap on the unused port to seal it effectively. A tightly fitted cap prevents air leakage, which can significantly affect vacuum efficiency. Any leak can reduce suction power, making your cleaning less effective.

After placing the cap, give it a slight twist to ensure it's securely in place. You can also use a rubber mallet to gently tap it into position.

Step 4: Check Engine Speed (Optional)

Use a tachometer to check if your engine speed is within the optimal range. An engine running at the correct speed will maximize your vacuum's performance.

Step 5: Test The Setup

Run your truckmount to ensure there are no leaks and that the vacuum is functioning optimally. Always test before heading to a job to avoid any on-site issues.

Why Is a Tight Seal So Important?

In our experience, a tight seal is crucial for optimal performance. Our research showed that a loose or faulty seal can lead to loss of suction, reduced cleaning efficiency, and even damage to your truckmount. 

A tight seal ensures that your vacuum system operates at peak efficiency, saving you time and money in the long run. It’s just as important as knowing what oil going on truckmount blower vacuum or how to organize truckmount vacuum hose without vacuum reel.

How Do You Know the Seal Needs Replacement?

Here are some telltale signs:

  • Loss of suction power
  • Unusual noises from the vacuum system
  • Visible wear and tear on the seal

If you notice any of these, it's time for a check-up. Vacuum seals not sealing properly should be inspected and repaired or replaced. After putting it to the test, we recommend conducting regular inspections to catch issues early.


So there you have it, folks! Sealing your vacuum inlet is a small but crucial part of maintaining your carpet truckmount. And it’s as easy as putting a PVC cap over the inlet.
