    Could not add another image using the add another image button. Safari Java script error?

    A safe bet

    It is a safe bet that this job is a contender if not a sure thing for some System Showcase accolades.

    Beautiful work Devan.  Is that grey melamine?  Very well thought out and I love the piping as it dissapears into the wall.  Your concealed wiring is top shelf.

    I think I will have to go "Tonya Harding" on you before the System Showcase Awards if I'm to have a chance.  :)

    Best to you,

    Wire on Pumps?

    Are those electric cords hanging on the iso-valves on the system pumps?  If so what are they for?

    nice layout

    I like the way you offset with the 45's nice work. Great components also.

    Yeah, I'm torn on the corded versions of the Grundfos. I like that you don't need to get inside, the pump to wire it, but it limits you to that wire??

    Thanks Paul

    was not really thinking about system showcase awards for this one, but I may have a few other jobs in contention ; )

    Yep, the Grundfos Alpha has a quick connect cord connection.

    Downside, you have to use it, I will probably finish up the wiring soon, I just

    did not want to cut those cords yet until I made sure they worked ok.

    It is pretty cool though when you close off zone valve , and you see the wattage drop as displayed on the pump.

    Forgive my ignorance, but how does one wire these Alphas to something like a Taco SR?

    Thank Rob

    Is that you NRT.Rob?

    Just cut the ends off the leads, then wire as normal into a taco,grundfos,argo or tekmar relay panel.
