Call

Burst Pipe

Shut the water off at the main valve, or cut power to the well pump if that is what feeds the house, then call before the split line finishes soaking the crawlspace.

When this becomes an emergency

What a pro does

Most burst-pipe calls on Delmarva trace back to a single cold night rather than a long freeze. The peninsula sees somewhere between 55 and 80 nights below freezing in a typical year, so the lines that fail here are the exposed ones: a hose bib on an exterior wall, an outdoor shower at a Dewey or Bethany rental, a supply run through a vented crawlspace with the thermostat turned down to 50. A plumber's first question on a call in Rehoboth or Ocean City is usually how long the place has been empty. On a private well the arithmetic changes, because there's no municipal meter spinning to give the loss away and the pump keeps cycling against a break it can never satisfy. That is why the pump breaker matters as much as the main valve. Once flow is stopped, the failed section gets cut out and rejoined with fittings matched to the pipe already in the wall, and the run gets pressure tested before the crawlspace hatch goes back on.

Frequently asked questions

It does, though not the way it happens further north. Delmarva averages roughly 55 to 80 nights below freezing, and one of those nights is plenty for a line sitting in a crawlspace, an unheated garage, or an outdoor shower stall. Houses held at a low thermostat setting through the winter are where it turns up most often.
Winterizing drains the lines so there is nothing left to freeze, and it works only if every low point actually emptied. A trapped pocket in a crawlspace run or a fixture that never got blown out can still split. Nothing shows up until the water goes back on in the spring.
The break looks the same. Detection is what changes, since there's no meter at the curb to spin and the pump will run against the loss until somebody notices or the motor gives out. Cutting power at the pump breaker stops the flow the way closing a main valve does on a Dover or Salisbury water connection.
Nobody is there to hear it. A house in Ocean City or on Chincoteague can go from October to April without anyone walking through, and a line that let go in January has had months to work into framing and insulation over damp sandy ground. Spring startup is when a large share of these get found.
