Galvanized Sewer Vents

Hello there,

While driving into a tight alley yesterday evening, the sewer vent cap or what was left of it was torn off by a tree branch. It looks like it's time to take out the puddy knife again and redo the base and cap. I've replaced a few of these in the past and know what to do but was wondering if anyone on the forum had tried the galvanized steel vents and caps. It would like kinda funny but looks like they would easily outlast the rig if installed properly. If you have experience with these galvanized cap and base or know someone that does. Please let me know how they hold up.

thanks a million.

    If it's the roof cap you're referring to, I'm not sure the galvanized version would be impervious to tree branches either. If the vent cap doesn't snap off its going to tear off your roof. Something's gotta give and I'd rather replace the less expensive part.

    stay out of the ally's and the metal caps I don't think they are galvanized either. while you are towing your TT you need to be more mindful of your surroundings.

    I got tired of replacing the cracked plastic caps so my replacements were made from aluminum cat food cans. I riveted the cans to the metal tangs that slip into the sewer pipe, painted the whole thing white and they stay put and will never crack. Cost is free.

    it says they are galvanized. I'm considering this vent and cap because it will likely holdup longer under the sun than plastic ones.

    We have the metal caps and lost one somewhere. We think it blew off in high winds in SD.

    I have been RVing since 1998 and never lost or had to replace a sewer vent cap so I think plastic ones will work fine.

    I like the metal ones too, but so long as you continue snagging tree branches, you will continue to rip them off as they are not impervious to damage from tree branches. I think you are better off damaging the cap instead of damaging the roof.

    My plastic cap is 18 years old and was looking shabby so my thought was to make one out of a metal tuna fish can and paint it white which I did but like the plastic one better, so I sanded the mold off and spray painted it white. I have painted it probably 3 times by now and it still looks good. The Fusion paint holds up nice on plastic parts.
