i just received my 0-3psi #33020 for the steam boiler. Now to put it to work.
I plan to take mthe pressuretropl off the pigtail and the with a T fitting abd a few brass nipples, and elbows, reattach the ptrol to one side of the "tree" abd the 0-3psi gauge to the other side. I will not touch the 0-30psi guage.
I am going to use a black iron union. that way I can get most of it together on the beanch. From the union, the retst will be breass fittings. Should I use the same sealant on both the iron and brass. Teflon and/or rectorseal #5 ?
We stil have the two-pipe, air vent system (1900??) with radiators with two supply valvers and air vents.
