    This is odd

    I have 2 Water Furnace customers who have called a day apart with a Water Flow light coming on.

    Never seen this before, where 2 of the same issues happen 35 miles apart at 2 separate sites. Both residential. Both Water Furnace.

    We have has quite a warm winter and spring.

    Would anyone have any idea what is going on?

    I have not been to either site yet.
    Can someone please explain to me -
    Why is there never enough time to do it right the first time, but plenty of time to do it twice?

    Would the ground frost have reached it's deepest point now and just starting to come back up?

    Snow cover this year or not?

    expansion and contraction in the loop.
    The pipe in the ground during the season will expand as it gets warm in summer, adding in the heat added to the water pushes the water pressure up.

    Winter, pipe shrinks, water pressure decreases due to less heat.

    This happens season by season, as long as you started straight up at about 40-50 psi, no problem.

    One summer, the pipe will expand....and not shrink back. Which is good. You'll be making more contact with the ground with more surface area.

    Winter comes, doesnt shrink back, water gets cold, shrinks, you loose pressure to the point your not pumping anymore.
    Especially if the geo is in the basement, and the water lines go up the wall before exiting the building into the trench.

    Bump it up. Call it a day. Dont worry about adding anti-freeze, you haven't really added any water. Maybe a quart.
    If it drops again, then yeah, you are leaking somewhere.

    DONT ASSUME ITS THE LOOP LEAKING!
    When your done bumping it. Stick around and watch it run. See if your getting leaking at the pumps. Happens all the time.

    Mr. Vegas,

    Thanks! Great info.

    Bumping it up was about where I was going to start. So that confirms my thoughts.

    Now that I recall I had a similar one a few years ago that I only added a quart or so to handle this issue. I think your response jogged my memory on that one.

    Your help is appreciated.
