    Insulation

    Hi,

    I work for a HVAC Contractor and occasionally work with the Geo Install crew. I was wondering what you guys are using to insulate the ground water pipes. We seem to be spending a lot of time wrapping pipes.

    I just wondered if there was another solution other than Armaflex.

    Thanks in advance.

    We don't wrap the pipes. They're buried deep enough in the ground so there's little temperature variation between the well and the house.
    If YOU want change, YOU have to first change.

    If you are waiting for the 'other guy' to change first, just remember, you're the 'other guy's' other guy. To continue to expect real change when you keep acting the same way as always, is folly. Won't happen. Real change will only happen when a majority of the people change the way they vote!

    thanks

    Our pipes are coming in the basement at about 3' below grade. How low are you coming in?

    We're about 8-feet down at the bottom of the foundation wall. At 3-feet we'd wrap them but we're never that shallow. But rather than wrap, we'd use rubbertex foam insulation that slides right on the pipe. It's got a talcum layer on the inside of the insulation that lets it slide right over the pipe. We use the same stuff on heating pipes of all types when doing conventional burnt air heat. Water pipes, refrigerant lines, whatever. We save the spit & sticky stuff for the last few feet if we can't push the non-split far enough down to make the final connection.

    Yeh, thats waht we are doing now. Real PITA. Hoping to find a better way. Way thinking there must be some sort of spray foam or something.

    Oh well, was a happy thought.

    Are you putting the armaflex on before fusing the pipe? I can't think that there is anything easer than sliding it on, hooking up the pipe and then gluing the insulation.

    Thanks for the reply local,

    Yes, the piping is getting insulated before fusing the pipe. The real issue is insulating the pipe at the manifold at the entrance of the pipe into the basement. A real PITA.

    Nomalock type insulation works ok.It always sucks having to insulate in the ground.Most jobs didnt need it as we were 3 feet or lower at the manifold or where the pipes enter the foundation.Sometimes I would use a straight length of 2"sch 40 pvc with a 2x1 1/2 fernco fitting on the end and slide the pipe through.
