Cool Tools: A cheater plumbing vent cap

It is common to have items on your RV roof become sun damaged and then eventually break or go missing. A common one would be the plumbing vent. There are many times that you can get away with replacing just the cap, and not the entire vent—where you have to remove the roof sealant and putty tape.

I want to introduce you to a cheater plumbing vent cap. This replacement cap is designed with a spring tension attachment, which eliminates the need to replace the entire vent. Simply insert it into the plumbing vent pipe, align the mounting screws hole and add a screw to secure it in place.

Here’s a little more about it…

Hey Dustin, nifty repair but it seems that the 2 metal tabs that go into the ABS isn’t enough to hold it in place, is there a way to also screw in place? Thanks for the information. Look forward to you & Dave on Wednesdays. Wish you were closer than a 6+ hour trip! Would be great just to visit your shop!

I agree with you Snoopy and wish Dustin’s shop was closer than a 16 hr trip, at least that’s what Google Maps calculates. I travel slow to be easy on my MH, for safety and to look at the scenery so who knows how long it will take… I plan to find out in Feb.
