Hi,
To create some traffic for our newcomer, I thought I'd ask for
recommendations for a penetrating oil to apply to stuck gate valves; the
typical kind found on 15 mm and 22 mm domestic copper piping.
I've had WD40 suggested, but it isn't the same thing.
I've quite a few stuck gate valves. Getting applying torque by hand,
back and forth until it starts moving has freed some. I've returned the
open ones to fully open less a quarter turn to help prevent future
sticking. Presumably that doesn't impact flow, with the gate only
cutting in after more turning?
The tap on the incoming mains is also stuck. :-)
what does Gemini/ChatGpt suggest?
dislocated my shuolder today. just got home. left hand typing only.
