First, you can insert a soft plastic tube with a diameter of 1cm into the frozen PPR water tube, then use a kettle to slowly boil water into the thin tube, and then slowly extend the cannula in until the ice melts and thaws. . You can also try pouring hot water outside the pipe and wait for the ice water inside to slowly dissolve. If the effect is not obvious, you can remove the water meter first, then insert a thinner plastic tube into the water tube, and heat the water from the thin plastic tube while inserting it. If it is not frozen deep, it can be melted. If the water in the water pipe has been frozen deep, it may not be effective to scald it with boiling water. The best way is to turn on the faucet a little to make the water flow before the weather cools sharply, so that it will not get stuck. ice. If the freezing is too deep, you can remove the faucet first, and then poke the red-hot iron pipe into the water pipe, so that the water pipe can be thawed smoothly. It should be noted that the floodgates must be closed in advance. If the part of the water pipe is frozen in the ground, try to thaw it by heating it with high current. This requires professional maintenance personnel to operate, do not do it yourself.
