I just found out that a slab foundation summer house we just purchased has orangeberg (fiber conduit) drain pipes.  I am told by my plumber that these drain pipes will need to be replaced within the next 10 years; but I do not want the expense and headache of tearing out the cement slab to replace it.  Can you offer any suggestions?  I understand that the orangeberg is very brittle and will not withstand an epoxy sleeve. Please help!

Gigi, because Orangeburg pipes are made of layers of wood pulp and pitch they’re not repairable. Epoxy lining is not an option, but if enough of the Orangeburg pipe is intact, it’s possible that sock lining might be. Sock lining consists of a felt sock being pulled through an existing pipe and then inflated/expanded to fill the width of the old pipe. The sock cures in place and you have a new pipe inside of your old one. I recommend contacting a reputable trenchless technologies company that offers sock lining services. You may be able to find someone through the website of the North American Society for Trenchless Technology, www.nastt.org.

Do you see epoxy lining emerging as the preferred choice for pipe rehabilitation for apartments, condos and commercial buildings?

-Tejas

Tejas, epoxy pipe lining can be the perfect solution for pipe problems in apartments, condos, and commercial buildings. It’s gaining popularity as an effective alternative to the more traditional repipe because it’s safer for drinking water than unlined metal or cement pipes; is often less messy, costly, and time-consuming; and eliminates the corrosion that leads to blocked or leaky pipes.

-Brian

In the municipal market, can epoxy lining only be used for wastewater, or can it be applied to drinking water pipes as well?

-Tejas

Tejas, epoxy lining can certainly be used in both types of pipes. For example, CuraFlo’s sister company, RLS Solutions, offers coatings for restoring and rehabilitating water mains (drinking water delivery), as well as deteriorated wastewater infrastructure.

I have a small leak coming from my shower. It is behind the one handle that controls temp. I took off the handle and all the caulk around it, and it looks like there might be a small crack in the plastic. Can I just put epoxy or something else on it? I don’t want to take the ceramic tile off to replace it.

-Jan

Jan, if there is a crack in a part of the fixture, especially in a part that’s plastic, you should replace at least that part. Repairing the part might work, but plastics can be difficult to repair and the potential damage the leak may cause if it reopens may not be worth it. The epoxy we use is only for lining pipes, but there are other epoxies and compounds that can be used in plastic repairs. I would contact the store where you bought it, or the manufacturer, to see if a replacement part is available.

I have a 12 year old home and I got a tiny pin hole leak in the copper pipe not at a connection. After getting it fixed, 3 days later a got another tiny pin leak inches of way. What could cause this and should i worry about the entire line?

- Jason

Jason, a single pinhole leak can be a fluke, but if you have more than one there’s a good chance that you have a systemic problem. A pinhole leak is the final breakthrough in an area of the pipe’s wall that has been affected by pitting –a form of corrosion. Replacing the section of pipe or the whole system will turn back the clock, but won’t stop the pitting and leaks from happening again or in different spots. You may be able to have your current pipes epoxy lined which would restore them to like-new condition and prevent water from coming into direct contact with the pipe wall.

I have a swimming pool that is leaking somewhere in the piping. Can some sort of a liner be put in the pipe to stop the leaks? The pipe is PVC and has several 90 degree bends.

- Ed

Ed, unfortunately your problem is the pipe material used, not that there are 90 degree bends. If your pipes were metallic, epoxy lining them could have been a solution. PVC (polyvinyl chloride) pipes, used in most pool installations, can’t have a lining installed. You’re going to have to excavate the pipes and then repaired or replaced.

What is the chemical composition of CuraPoxy? How safe is it to drink water from pipe lined with this as compared to other plastic pipes and water containers?

-Gerry

Gerry, while I can’t disclose the chemical composition of CuraFlo’s epoxy, CuraPoxy®, I can tell you that it’s certified to meet ANSI/NSF Standard 61 which is the U.S. government’s standard for safe drinking water. This standard has been in place since 1988 and has been used to certify over 12,000 products. To find out about the safe for drinking water certifications on plastic pipes and bottles I recommend you contact their specific manufacturers directly.

Does CuraFlo lining contain BPA?

-Roberta

Roberta, CuraFlo’s epoxy, CuraPoxy^® is certified to ANSI/NSF Standard 61 –the established governmental safety standard for drinking water system components. That certification ensures products are free of unsafe levels of contaminants such as BPA (bisphenol-A). For more information about how epoxy and polycarbonate products (water bottles) differ, please refer to this previous post of mine on this very topic.

My back yard drain (partially under cement) is the old orangeberg pipe. When it is snaked out to remove and roots etc I am now receiving parts of the pipe. Total replacement would be tremendous. Can one sleeve orangeberg and is it economical? Can one use  the epoxy liner to fix?

-Richard

Richard, Orangeburg pipe, also called “fibre conduit”, is made from made from layers of wood pulp and pitch (for more information, see the article on Wikipedia here). Because Orangeburg lacks in structural integrity (even when it was new), it’s not a suitable host pipe for epoxy lining. It might be possible to sock line Orangeburg pipe if enough of it is intact, but you’ll need to consult with a company that offers these services to find out. The North American Society for Trenchless Technology’s website, is a good place to start looking for companies that offer different trenchless solutions that might have a solution for you, or at least offer additional insight.

Does copper kill fungus or Bacteria? What is the effect of epoxy lining on Bacteria?

-Don

Don, copper won’t kill bacteria or fungus –in fact, in both copper and galvanized steel pipes, bacteria and other microscopic organisms grow in encrustation on the corroded pipe wall or on the corroded areas themselves. Epoxy pipe lining prevents corrosion and encrustation by creating a barrier between the pipe and water. The bacteria and other organisms will no longer be present to cause bad tasting or smelling water.
