Our RV is getting older, and as such, she’s needing a little maintenance and updating. Hmm, couldn’t we all? 🤣 At least twice a year, Al and I head up to the roof of the RV to check things out. More frequent visits would probably be even better, but when we’re confronted with landscapes that are so stunningly beautiful and beg to be explored, who wants to work on RV projects?
But regular RV maintenance is necessary, and most projects aren’t very difficult; therefore, there’s really no excuse. With that said, it is something we consciously try to make a priority if we want to keep the RV in tip-top shape. Thus, the travel and exploring gets put on hold temporarily while we dive into maintenance projects.
So, up on the roof we go. After checking all the vents, caulking, and general condition of the roof, Al and I determine that the sewer vent caps should be replaced. One cap is severely cracked while the other looks compromised. We’re not sure if they were damaged by hail or a tree branch. Regardless, we’ll replace both caps.
For this post, I’ve partnered with a great RV parts company called Road & Home. Although we’ve received some free goodies from them, all opinions regarding their products are my own. We first discovered Road and Home products during a shopping trip to the local Lowe’s.
RV maintenance made easy
It was a Sunday afternoon, and since most RV dealerships in Arizona are closed on Sundays, we headed to Lowe’s for some general plumbing fittings. We’ve had a tiny fresh water leak in our storage bay that only leaks during the clean water flushing stage of dumping our black tank. It wasn’t an urgent repair, but a needed repair nonetheless. A new fitting should fix up the leak, so off to Lowe’s we go.
Lowe’s had everything we needed to fix the plumbing leak, but much to our surprise (a pleasant surprise), they even had the sewer vent caps that we needed for the roof of the RV. We didn’t even realize Lowe’s carried any RV parts, but there we were standing in front of a large display filled with a variety of RV products from Road and Home.
Fifteen minutes later, along with half a dozen products in our shopping cart, it was time to head back to the RV to get to work. With storms expected in the next few days, first and foremost was replacing the roof vent caps.
How to replace a RV sewer vent cap on a rubber roof
Step #1 – The first step is to gently remove the existing vent from the rubber roof. After removing any visible screws, snap off the top cap. With a blow dryer, heat the existing caulk and with a plastic putty knife, gently pry and separate the caulk from the rubber roof. You’ll want to be extremely careful not to rip the rubber roof which is why we don’t recommend using a metal putty knife. This process might be a little slow going, but be patient … we don’t want to compromise the integrity of the rubber roof by damaging it.
Step #2 – Once the old caulk is removed, use a soft clean cloth to wash the area, making sure the surface around the sewer vent pipe is clean. We just used plain water, no soap.
Once the area is dry, lay down a layer of plumber’s putty. We already had a roll of RV sealant/putty in our tool box.
Step #3 – Now it’s time to screw down the bottom section of the vent and install the top cap. The top cap snaps on and there’s one screw on top to hold the cap down.
Step #4 – Now comes the cake decorating portion of the install … otherwise known as caulking. This is when I (aka cake decorator) step in to finish up the job. Using Dicor lap sealant with a caulking gun, I liberally apply a large amount of sealant around the base of the vent, and use the plastic putty knife to help spread out the sealant. This stuff is not normal caulk and may take a little practice to make it look somewhat close to factory install. The tube may say self-leveling, but that doesn’t mean self-smoothing!
Although replacing both RV roof sewer vent caps was a little time consuming and tedious, overall it was a relatively easy DIY project. Thank you, Road and Home, for making this RV maintenance project even easier with the convenience of being able to buy everything we needed at Lowe’s (available on Amazon too).
