I'm not trying to be difficult, but does it specify potable water service temperature range?
Unless it's at least 250°F, it probably should not be used on an espresso machine.

Many industrial chemicals have a maximum permissible level of a few parts per BILLION and some have NONE.

Asking the question is almost as easy as looking up the answer :wink:

Given the extremely tiny amount used, the surface area exposed and the lack of signifcant flow at the location where it is used I'd not worry anymore than when using PTFE tape (Teflon is no saint either)

You?? Difficult? :lol: Rectorseal #5 is the standard sealant used by the vast majority of professional plumbers in the U.S. when they install household water systems. It's been around a long, long time & if there were any issues they'd be well known by now.

rectorseal is the correct sealant for house water systems; suggest loctite 55 pipe sealing cord on espresso machines

Hi Camino,

I'm very interested in understanding what you learned from CC that indicated the boiler issue was tripping your GFCI. I have a La Marzocco that just started tripping my GFCI, this was after a move, and I'm trying to figure out where to start the troubleshooting.

Thanks,

A GFCI trips when there is a small current in the earth safety. It can be caused by water in a connector, bad heating element, leaky motor, a moist salt path.

Over current load.

GFCI also go bad.
