  • are those flow check valve and swing check valve important?

    We did oil to gas conversion last November (http://www.ridgidforum.com/forum/showthread.php?t=29244). The boiler is Burnham Alpine. The plumber told me he would follow the manufacture's instruction (see the attachment please) to layout the pipe. I just found he didn't put the Flow Check valve on the top left and the Swing Check Valve before the Boiler Loop Circulator.

    Are those check valves important or not? Do I need to ask somebody to add them in?

    thanks,

    did he pipe the system with circulators or with zone valves. If zone valves the flow checks arent neccessary, or the cirulators may have the flow checks built in like these:

        He did the system with circulator not zone valves. The zone circulator is Taco 007-F5-12 which has no integral flow check. The Boiler Loop Circulator is Taco 007-F5-1IFC which has integral flow check. I guess he forgot that flow check valve.

        needs to be added in?

          If you had summer/winter hook up, I would say without a doubt there should be a flow valve installed. Straight heat only (didn't look at the diagram) you may have to install a flow valve, so the heat doesn't drift to one of the other zones that's not calling for heat. But if you had zone valves on straight heat only...you don't need a flow valve. If you only have one zone (which I doubt you do) then it's a non issue.

            Based upon his first post..... he has one zone. Moot point.... no need for any check valves.

            Why are you so uncertain about your installers work? Just wonderin?

              Didn't realize there was another thread with this boiler in question. After seeing those pictures, I do not care for the way the boiler is piped at all..especially the auto feeder! If the Plumber was going to to that, he should of used the Amtrol fill-trol set up, and back feed the boiler if he wanted too.

              1 zone is a moot point, and I don't understand why this guy keeps asking these questions about his installer.

                read from other place which says the flow check valve is important if you use circulator. after checked mine, no flow check valve was installed. so ask here to see if that valve is really necessary.

                  There are lots of REAL experts here. Check with their opinon and ask them questions can learn a lot. For example, I learnt from you that one zone circulator layout is ok without check flow valve but check flow valve is important on multiple zones circulator layout.

                  When I add more zones, I will ask plumber to add that check flow valve in. I want to be an educated user.

                    Our point is maybe you shouldnt be using your installer if your doubt his knowledge abilities and judgements so much. maybe you should interview your installer based upon his know how so you can rely on his judgements as opposed to a website of real EXPERTS who arent at your house that are able to see all the reasons your installer may have had to do what he had to do.

                    we cant see what he does so it isnt fair for us to judge what he knows. this is the reason that you hire someone based upon what the know, not how low their price seems to be.....
