Hi all,

Has any one used flex and seal wrap (tape) on waste water plumbing on their RV? Asking for a friend who has a plumbing problem.

Would eterna bond work?

Hi piano,

See this thread where a similar question was asked. I have much more to add if needed, http://forums.trailerlife.com/index.cfm/fuseaction/thread/tid/30301229/gotomsg/30301329.cfm#30301329

In these plumbing leaks situations, it really helps to know more about the leak, and ideally, see some pics of the leak area. I know you are getting this 3rd hand, but get some info from your buddy and we can help better.

If there is a cracked tank, cracked pipe, cracked tank fittings, this all comes back to, where is the crack and what caused the crack? Knowing some about the first topic helps greatly on backing into what caused the crack. Then comes how to make a band aide to get by if needed to get you home, followed by a permanent repair that removed the temporary patch and does a permanent fix.

This much I can say, Eternabond is not a long term repair on a RV tank/plumbing system in "most" cases. I have used a lot of Eternabond, and it is really good stuff when applied right, just this is not the right application. Ebond has no mechanical strength to reinforce the leaking joint to not continue ripping or leaking long term.

We really need to see and know more about the leak to help guide you better. Putting flex seal etc. on as a band aide may contaminate the area making a permanent fix harder to grind out, scrape off the goop put on wrong.

ABS plastic that most RV waste systems uses is very repairable, permanently. From small cracks, to mega missing parts ripped out of the tank, using an ABS solvent weld method, ABS plastic sheet filler, ABS pipe, fiberglass reinforcing mesh and, addressing the original reason why the crack/leak happened in the first place.

Hope this helps
