Clear Valterra Waste Cap

I wanted to try the Valterra T1020-1CLR Clearview Waste Valve Cap - 3" with Capped 3/4" GHT for some time. A recent thread reminded me, so I ordered two for my trailer with two drains. This didn't work out well.

First, the stickers had to be removed so that one could actually see thru the clear cap and that was wasn't easy. Also, I might get cancer now if I use these in California.

Second, the 3/4" hose connection threads were way too tight and the caps couldn't be installed. I spent over an hour lapping them with valve grinding compound. Now they fit properly.

Third, these things only have two locks instead of the more reliable four, and they have no detent to keep them in place.

Fourth, I tried to install them and they would not go. The gaskets are super glued in place at four locations and that prevents them from being compressed enough for the locking tabs to be engaged. I dug out one gasket destroying it in the process and my spares are of a different design.

Fifth, one locking tab on each has an air bubble weakening it.

I am requesting a refund, they are totally useless.
  • I bought one to avoid surprises and I wanted a cap with a garden hose output that I can use either to easier drain those surprises or drain the gray tank with a garden hose, like when at home.
  • I got mine off the shelf at CW and they work great without any mods. Nice to see if there is any liquid present and if so to be able to drain it without taking off the entire cap. My trailer has two dump stations.
  • Just scan a standard cap with your laser scanner and print it clear on your 3D printer :B
