Old lead-free Taramet Sterling Solder
I forgot to check my dad's old plumbing box before soldering up the heating/plumbing pipes for my combi boiler. Turns out there's almost a full spool of Taramet Sterling in there.
Did they change the formula for the 2011 low-lead requirements, or is this still good for potable water pipes? I'm running out of my new Harris Sterling.

Single pipe 392sqft system with an EG-40 rated for 325sqft and it's silent and balanced at all times.

You're good to go unless you live in California....they MAY have changed there thresholds. By the way, Taramet Sterling has been my favorite solder for many years. Mad Dog

Thanks. It looks like it was set to 0.2% in 1986 and remained unchanged in 2011, with the 2011 rules mostly impacting fittings <0.25%.
Do they still sell Taramet? Maybe under Harris? Label looks like my Harris spool.
