possable leak

[Deleted User]

i just bought this house 2 months ago the boiler was inspected and had a couple things replaced . now that the
cold season is here i keep loosing pressure in my boiler .
i fill about 5 lbs every 4-5 days . i was told i may have a leak in my pipes that run under some concrete in my house . just the sound makes me think high cost to fix .
the lower part of my house where this is is on it's own loop . is there any way to avoid hammering the concrete to
fix this problem , or better yet does anyone have any suggestions .

thanks
mike

Starting by shutting of that loop and seeing if that is in fact where your leak is?
