About prevention of freeze of water pipe

Last update date December 28, 2020

If temperature becomes below the freezing point, water in water pipe freezes up, and water does not flow and water pipe explodes and may leak water.
I would like cooperation for prevention of freeze of water pipe as follows.

Water pipe which is easy to freeze up

  • Pipe which has exposure (show) outdoors
  • Pipe of place where it is in the north side of house, and positive does not hit
  • Pipe in wind-swept place

※When it becomes -4 degrees Celsius in particular or less, attention is necessary.

The way of cold protection to be possible in ordinary household

  • We completely give in heat insulator and blanket, scrap of cloth to the top of faucet.
  • We put blanket or scrap of cloth Styrofoam of stump in the meter box to protect meter and keep warm.
  • When faucet produces water little by little in bathtubs, it becomes hard to freeze as water drifts consistently. (in addition, please be careful as you take water rate of thing that you spread.)

When it becomes absenteeism for the winter season

When we go out as water pipe explodes by cold wave and may leak water when it becomes absenteeism, we would appreciate your closing valve (supporting stop cock) in meter box.

When water pipe has frozen

  • When faucet froze, you wait to melt naturally or cover part which has frozen with towels, and please hang tepid water slowly.
    ※Pipe and faucet explode when we sprinkle suddenly hot water, and attention is necessary as we may damage feed cock.
  • When water does not flow even if we open faucet by freeze, you may have opened faucet, but please close faucet by all means even if water does not appear.

When water pipe has exploded

  • When water pipe and water meter (meter glass) exploded, you close valve in meter box as far as you can do it, and please turn off water. At this chance please apply for repair after blocking up point that exploded with cloth or tape. But please be careful not to be hurt by pieces of glass.
  • As, about leaks of water from water meter to faucet, we cannot repair in Water Works Bureau,Private water supply works shop (list of meter downstream side leak of water repair companies)You pass, and please ask for repair. But Water Works Bureau changes explosion of water meter (meter glass) free. In addition, as we may repair free when it leaks water near water meter,Water Works Bureau customer Service CenterPlease connect with this.

In City of Yokohama, Water Works Bureau

  • We organize patrol group during period in the winter season and keep in mind for repair in early detection, early stage of leak of water to cause slip accidents.
  • When cold wave is expected by weather forecast, we are doing antifreeze appeal with broadcast car.
