To provide a water supply maintenance method capable of replacing an old pump group with a new pump group while maintaining the water supply.SOLUTION: A water supply maintenance method comprises: a step of closing a front valve 21 for a pump 61 of a first pump group 61 to 64 and removing the pump 61; a step of arranging the pump 61 outside the first pump group 61 to 64, connecting between a front parallel pipe 11 and the pump 61 by a front bypass pipe 71, connecting between the pump 61 and a water faucet mounting part 139 by a rear bypass pipe 72, and opening the front valve 21; a step of replacing the first pump group 61 to 64 with a second pump group 81 to 84, connecting the pumps 82 to 84 of the second pump group 81 to 84 to a pre-stage valves 22 to 24, and opening the pre-stage valves 22 to 24; a step of removing the pump 61, the front bypass pipe 71, and the rear bypass pipe 72; and a step of connecting the remaining pump 81 of the second pump group 81 to 84 to the front valve 21 and opening the front valve 21.SELECTED DRAWING: Figure 2
【課題】給水を維持しつつ古いポンプ群から新しいポンプ群に取り替えることができる給水維持方法を提供する。【解決手段】本実施形態の給水維持方法は、第１ポンプ群６１〜６４のポンプ６１用の前段バルブ２１を閉じ、ポンプ６１を取り外す工程と、第１ポンプ群６１〜６４の外部にポンプ６１を配置し、前段迂回管７１により前段並列管１１とポンプ６１の間を接続し、後段迂回管７２によりポンプ６１と分水栓取付部位１３９との間を接続し、前段バルブ２１を開く工程、第１ポンプ群６１〜６４を第２ポンプ群８１〜８４に取り替え、第２ポンプ群８１〜８４の一部のポンプ８２〜８４を前段バルブ２２〜２４に接続し、前段バルブ２２〜２４を開く工程と、ポンプ６１、前段迂回管７１、及び後段迂回管７２を取り外す工程と、第２ポンプ群８１〜８４が有する残りのポンプ８１を前段バルブ２１に接続し、前段バルブ２１を開く工程と、を備える。【選択図】図２
