Hey All,
We recently bought a HUD house and the inspection done by HUD was ok, they said the pipes help pressure when air tested but that ice blockage in the line prevented it from being inaccurate. Do you think we are in a world or problems with this house? Please give valuable suggestions.
Thanks in advance

Ice blockage? Are you close to the Arctic Circle?
Are you talking about the AC? Refrigerator? More information, please.

I would guess that it means they were simply unable to test the entire system.

If you pressurize the line at 1 end and part of the line is blocked, but you have a leak on the far side of the block, then the pressure test will not find that leak. If the ice block is 1 inch away from the pressurization point, then it wasn't really tested.

That they let the line freeze with water in it could be a little bit of a problem. If there is enough water in the line and it freezes, it can rupture the pipes and you would need to put in new water lines. It isn't the end of the world but could cost a few hundred to a couple thousand dollars.

It’s not really clear from the original post what the report says. Water supply pipes are supposed to be routed below the depth to which the ground can freeze in the winter and are also supposed to be otherwise protected on the run into the house. Not quite sure how the supply line could freeze solid…

The only other option I can see is that the inspector installed a freeze plug intentionally to seal the system off from the main line out to the street. I’ve used freeze plugs before but never heard of anyone doing that in a residential application.
