Copy and paste the whole thing from dielectric union back to http. Some are saying (in other websites) you won't have an issue with a closed loop system, their reasoning is that there isn't the introduction of oxygen. My thought is to better to be safe than sorry, but then again I'am picky. If you notice to, the pump in the same picture has brass fittings on both ends. - a guest Wed, 22 Dec 2010 08:53:00 +0100 /component/content/article/1-latest-news/35-a-new-gas-boiler-for-our-house#comment-3 JA, You will need a brass nipple or a dielectric union where your copper connects to the iron pipe otherwise you will have an issue with electrolysis. http://wiki.answers.com/Q/Can_you_screw_a_copperfitting_into_a_cast_iron_pipe_without_a_dielectric_union - a guest Wed, 22 Dec 2010 08:29:06 +0100 /component/content/article/1-latest-news/35-a-new-gas-boiler-for-our-house#comment-2 [img]http://www.iburncorn.com/images/boilerchangeout_dec10_15.jpg[/img] Here is a better shot of the bottom pipe. I don't think it is galvanized, just plain old iron pipe. As you can see, I wanted to turn it out. I had the pipe wrench on there with the imitation big muscles on the end of it (in the form of a four foot section of pipe on the handle) No luck. I couldn't get it to turn. - jabbott Tue, 21 Dec 2010 23:04:37 +0100 /component/content/article/1-latest-news/35-a-new-gas-boiler-for-our-house#comment-1 In looking at your pictures of the story you posted on the front page, it is hard to tell, but it looks like the picture with the heading "temperature guage with low drain", it looks as though you have copper connected directly to galvanized. Hard to tell in picture though. Overtime it will look like the picture you have posted above that with the heading of "corroded pipes another problem". You should have a piece of brass in there or a dielectric fitting. Glad to see that you got everything going again. - Binford Tue, 21 Dec 2010 22:04:00 +0100
