Have had a few pinhole leaks in house Copper water pipes.
Certainly don't want to re-plumb the whole house !
Anyone have any experience with the epoxy lining treatment for these
house water pipes ? Please see:
Was also particularly wondering about:
- Health safety aspects of drinking water thru epoxy pipes ?
- how do they handle pumping the epoxy with all the valves in the house;
faucets, shower valves, etc. ?
- what happens at the 90 degree elbows ?
- how "popular" is this technique ? Proven, experimental, etc. ?
- what are the negatives and caveats to this approach; there are
undoubtedly, I would think, some ? Cost aspects ?
If I were you I'd not mess around with things like that. Fix the problem
proper and live happily ever after. If you keep trying gadgetry,
at the end the money spent will be lot more than fixing right first time.
Hey Bob. This is really the same question as your earlier thread.
Probably best to keep the whole shebang in one thread, including
aspects that go off on a tangent.
That article link you posted addressed the cost.
"Water supply pipe epoxy relining generally costs about the same as
removing the old pipes and installing new ones; including the cost of
average surface refinishing after the fact. The homeowner benefits
from the longer warranty on the epoxy method and the quicker
completion. Homeowners with upgraded finishes and larger homes will
find the relining process to be the least cost approach."
I don't recall you answering where exactly the pinhole leaks
occurred. At fittings? All over the house? Middle of runs?
Leaks seem to be only (so far) in horiz. run on ceiling.
True "pinhole" size.
One at end of run, one in middle.
Ah, the joys of owning a home !
Thanks for help, appreciate it

I would replumb with PEX using a manifold and homeruns to each
PEX is cheap, tolerates freezing, with homeruns no buried Ts in walls
PEX is the way to go.
I wouldnt want to use water after it laid in epoxy coated lines, and
any coating will mae lines smaller
This is the first I've read of lining fresh water pipes. I've heard
of it done
for sewer pipes. Even, then, I've only read about it, don't know of
who actually had it done. Would suspect it's not that common.
because of the cost issue, which the link addresses. If the cost is
the same as replacing with copper or PEX, I would think the only
advantage to lining would be for cases where replacement would be
very difficult, eg below slabs inside a house, etc.
The epoxy is probably safe, but if it were me, I wouldn't trust it.
worried that even if epoxy is theoretically safe, how do you know the
mix used in your pipe was completely blended, cured, etc?
Drinking water after the epoxy cured wouldn't bother me any but I
really have to question how they get a good layer on the top half of
the pipes. It's got to be a liquid and that means gravity is going to
affect it. In the case of waste pipes having a better coating on the
bottom side of horizontal pipes is probably a good thing. Not so with
pipes under pressure. I agree pex from a manifold is a superior
plumbing solution but I would not replumb a house because of a few
pinhole leaks in some copper pipe.
I don't understand your logic. Why else would you replumb a house
other than the fact that leaks are occurring in random places? That
was the reason I asked Bob about where the leaks occurred. Since one
was at the end of a run (fitting/flux problem possibly) and the other
in the middle of a run (probably bad pipe or bad water - and both of
those are system wide problems), I'd be seriously looking at
investigating further - pipe surgery - with an eye toward replacing
I don't think I've *ever* seen a pinhole leak in a properly installed
copper water pipe... and some in my house are probably original to the
house (late 40's) what would cause this? certain contaminants in
water? I guess I've never lived in an area where I had to worry about
My parents are on a well... no probs... grandparents were too when
they lived out in the country, don't know when the indoor plumbing
dated from but house was built in 1880s. Again a lot of that copper
was probably original install. Don't remember hearing of any probs
In fact, the only plumbing issues that I ever remember having all had
to do with water heaters, and most of those were T&P valves that got
weak, popped off, and didn't close again. One tank rusted through.
No water softener; water felt a little hard but was never tested. And
I agree with you. I was not trying to be argumentative, I really just
have all my life had the idea in my head that copper water pipe was
not something that ever went bad, and this whole discussion is
completely new to me.
No sweat. Nothing lasts forever (well, maybe gold), and certain
things that seem more or less bulletproof, aren't, if you have the
right bullet. Certain minerals and elements react just fine with
copper - meaning it's not fine for you and your plumbing.
Maybe if this was the thrid or forth time he had the same problem but
he's just had one problem. That could simply have been a bad piece of
pipe. Tearing out all the pipe and replacing it will be expensive.
The pipe leaked in two place, not one, and the OP said the pipe was
Pinhole leaks can be just as damaging as a catastrophic leak. Pinhole
leaks may not show up for months or years, and by then mold and rot
will be a bigger problem.
I did say that I would investigate the situation of the pipes more
fully to help determine what needs to be done. That was the last
sentence of what you quoted.
Not tearing out pipes could be just as expensive, or more so, than not
tearing them out when he should have.
An exercise in futility.
Do it right.
Do it once.
Do it frugally.
Do it in PEX.
Not redoing the whole house with something that works makes people
wonder why you insist on a band aid solution that is known to have
many caveats and is very costly.
Time now to get on with finding a good plumbing contractor. Good luck.
well its his wallet, no cost to me when he tries having insides of
water lines coated, and gets a leak later....
he can let us know how it goes, and give perodic reports. and if a
leak still occurs in future, how much it cost to fix.....
floods are pricey repairs......
