    Backflow valve
    Just installed new main water line from meter to house. Water pressure to the house is good however no water in the house. Noticed a backflow valve and old shut off valve under the house (crawl space). Could either prevent water flow to the house? Water has only been off for two days after main line broke.

    Both the backflow preventer and the shut off valve are capable of stoping water from entering your house. If the main broke it's possible that dirt and soil got into your system and is clogging your lines and faucets. Good luck, Tom

That is the only replaceable part besides the gauge. Could something be stuck in the water pipes leading into the house? I am at a loss and so is...
