[SEL] Soldering galvanized question.

[Curt]

Guys,
Working on the last details of the Baker Monitor project and I am down 
to preparing the pail that the pump is going to pump water into. I am 
planning on hanging a galvanized pail from the pump and a pipe connected 
to the pail will drain water back to the tank under the cart.
I am thinking about soldering the pipe into the bucket.
It has been a LONG time since I watched gutter guys soldering sections 
of galvanized guttering together. As a child I recall them treating the 
sections to be soldered with something to make the solder wick and 
stick. But I don't recall if it was straight acid (muriatic?) or if it 
was killed acid.
Anybody remember?
Thanks,
Curt Holland
