Question:

Has anyone found a good way to clean a 2-inch sight tube on a vacuum truck? I can’t find a soft brush for this purpose.

Answers:

I used to just replace it.

I use a water jet. If that doesn’t work, replace the sight tube.

Do you drain the sight tube at night if you’re parked outside so it doesn’t freeze? Is the process shutting off ball valves and undoing the caps, and then drain into a bucket?

◆  ◆  ◆

I’m interested in the sight tubes. My trucks use the glass bowls. What material is the tube constructed of? How long do they last? Have you ever had an issue/emergency with one breaking?

◆  ◆  ◆

Yes, I have had one freeze and crack, so I switched to using 2-inch milk hose. It freezes but doesn’t break or crack. Just make sure during installation that elbows are mounted so the hose drains completely when the truck is emptied. I had this done wrong the first time. I can post photos of my current setup. The blue-colored hose actually stays clean longer. I have an extra tube made, and swap hoses when they get too dirty.
