Ice in zone valves and PVC.

    90% of our winterizing jobs have the manifold above ground. I tell all "calling" customers to shut off the water, open all drains, and cover valves with blankets or whatever.

    We went to several customers' houses today and found several with ice in valves and PVC. I carry a hair dryer but after trying this it would take hours to thaw the valves to allow air through. We do not want to dig up underground lines and tap in to winterize, for obvious reasons... Any ideas to thaw out above ground iced up zone valves????

    We had several customers with frozen PVB's and we will repair as needed before winterizing. Go figure. We did not know so many folks were in ND for their first day.

    PITA to arrive at customers house and valves will not open and will have to go back again when the temps warm up. Or at least they are supposed to warm enough for us to get the work done. But the backlog is getting large with the adverse temps..

    Thanks for all the help folks,

    John:cry: :cry:

    If they're not frozen to bad just turn the water on and lt each zone run about a min. Then you should be able to blow them out.
