Removing plumber’s epoxy

If it's actually an epoxy I'd expect acetone (nail polish remover) to soften it.
You need to soak it in acetone using a wet rag or other means for a while.
Please read the precautions on using acetone, I'd recommend plenty of ventilation and fresh air.

Channel locks and a good twist. My dad used a lot of it and is the only person I know who used it successfully. We're still finding that stuff.0

I had to chuckle when I read the title. Real Plumbers don't use epoxy putty or the black gooey spray that seals a boat hull, as seen on TV.
I would call it Hacks Putty or Homeowners quick fix to keep the Plumber away. The Husband puts it on and the Wife calls us Monday morning. Funny how that goes.0 -
If it's plumbers putty that stuff does get like a rock when it's old. Only thing I've had success with is mechanical removal, plastic scrappers etc. Most of the time I've encountered it was near finished surfaces so I try and avoid metal tools so I don't destroy any nearby finishes.
A lot of patience is required.
If it's actually some kind of epoxy....even more patience will be required.
Pictures of what you are doing would help identify what's going on.0 -
photo: tried to seal pinhole leak but didn’t turn water off and drain so fix failed. Notice many spots with corrosion further on down the line. Probably should replace with pex or what should I do since many potential pinhole leaks are forming.0

Hi @zvalve , Looking at the pipe, I agree that replacing with PEX is a good way to go. I might use Uponor or a system that doesn't use insert fittings, so you maintain good flow. Do you have access to a water quality test? I'm curious about the water.

Speaking of sharkbites a while back a contractor posted on FB that he thought it was funny all the professionals do nothing but bad mouth sharkbites and yet the supply house he goes to sells tons and tons and no DIY or homeowners go there.mattmia2 said:Normally I don't recommend sharkbites, but they would be a lot better than epoxy.

mattmia2 why don’t you recommend shark bites? Don’t’ you have to solder a fitting to the copper pipe to use the Uponor fitting as well as the purchase of a $250 expansion tool?0

Either learn to solder or sharkbites. It'll likely be fine as long as it's in a place that's accessible.
You need to do something and I'd try to get as much of that copper replaced as possible.
For what it's worth I consider my self pretty good at sweating pipe and I've found Uponor brass fittings to be less than easy to solder for whatever reason. I got the work done, and they were quality joints, but it wasn't as easy as normal fittings.Single pipe 392sqft system with an EG-40 rated for 325sqft and it's silent and balanced at all times.

I agree. But my new experience with pro-press relegated sweating to "only if out of viega pro press fittings" and shark bites to "in case of emergency"ChrisJ said:zvalve said:PC7060 maybe so, I’m no pro but what do you recommend for a lowly DIYer who can only afford $40 Harbor Freight tools?

@ChrisJ Were the Uponer fittings you were using lead free? If so they will not transfer heat as well as a normal brass fitting. Or maybe Uponor just uses an alloy that does not solder as well. Just a few thoughts.ChrisJ said:zvalve said:PC7060 maybe so, I’m no pro but what do you recommend for a lowly DIYer who can only afford $40 Harbor Freight tools?

The Uponor ones seem different, like you need to be extra extra careful especially with cleaning. I ended up using Bridgit solder and tinning flux on all of the lead free brass including the Uponor.Single pipe 392sqft system with an EG-40 rated for 325sqft and it's silent and balanced at all times.

They are really heavy so they take a lot of heat. I switched to using npt-propex adapters npt copper adapters because I would rather be able to easily reuse or reconfigure the like $6 propex adapter. The propex fittings are so expensive that copper tube is usually cheaper overall.0

I got pretty good at sweating fresh unused copper pipes with leaded solder but that was 20 years ago and when I recently tried to sweat some joints with pipe that held water I had a hard time getting the pipes dry and my joints failed or were cold soldered. I may have used lead free solder as well so I bailed with shark bites. Seems as if there is more of a learning curve with lead free solder and the pro press joining methods as opposed to shark bites. In any case thanks all for your input and help and found that heat and a razor blade scraper were the best tools for removing plumber’s epoxy
and don’t use the stuff to fix pinhole leaking pipes but an old piece of rubber garden hose and a hose clamp works in an emergency.Instead, do the job right with sweating on new pipe, or shark bites with pex B or Uponor and pex A or pro press fittings. Didn’t realize there were so many new joining methods for copper pipe and that there was a pex A or B. I was old school and thought sweating joints with lead solder or barb fittings with hose clamps around polyethylene pipe was all there was.0 -
If you can't keep the water out it's nearly impossible to properly solder the joint. Common trick is to stuff some white bread in the pipe prior to joint assembly. This trick usually buys you enough time to properly solder the joint.0

I also run the torch around the pipe before I flux it to cook any water or moisture out.DJD775 said:If you can't keep the water out it's nearly impossible to properly solder the joint.

I was going to say just solder in a new section, but thought better of it if he's getting pinholes. Pex would be a better bet here.😲ChrisJ said:

From the looks of the blue deposit on what appears to be the original pipe, I question if this home has a stainless water tank or a tank with a depleted anode rod. I've seen pinhole leaks develop in hot water lines where water quality was very soft and where there are no sacrificial anodes to protect the system. Adding a high temperature inline filter canister filled with cut up magnesium anode rods seems to protect the system and prevent future leaks.1

I've never used that bread trick.
Jet Sweats are very good.
A Copper x Female tee with a brass plug so steam can escape.
Crack the nut on the Water meter.
Any time I'm installing a new main shut off valve after the water meter, I'm putting a Copper x female tee with a boiler drain....so u can do a proper drain down AND if the valve don't hold down the line, your diverting that water so you can solder.. You DIE for one of those when you can't get a good shut down and wonder WHY no one 🤔 puts one in ..its easy enough..
I really love soldering and brazing...always did...Mad Dog 🐕0 -

I LOVE those European style split ring clamps with rubber. First time I saw them was In Bavaria in Seppe and Wick's (RIP) Homes in the boiler rooms 2005ish? Where you git them, Mattmia? Mad Dog 🐕0

I've used Propoxy on Holes in Cast Iron radiators and boiler blocks, leaking holes in lead bends...Temp fixes that weren't breaking the bank..especially for old folks. A potention $1000 dollar repair was done for $125 and wound up holding for many yrs..Mad Dog 🐕0

I got them from supplyhouse.com but I think they went out of stock after I ordered them.Mad Dog_2 said:I LOVE those European style split ring clamps with rubber. First time I saw them was In Bavaria in Seppe and Wick's (RIP) Homes in the boiler rooms 2005ish? Where you git them, Mattmia? Mad Dog 🐕

I'm pretty sure i bought a bunch of 1.25" cts clamps and I don't see that size in their catalog anymore.
I like them because they electrically isolate the pipe from whatever metal the clamp is made out of and from the support structure, frequently damp masonry. Those copper plated steel clamps seem questionable at best against copper.0
