同層排水於西元2023年元月起正式納入於建築技術規則及築物給水排水設備設計技術規範中，雖目前法令中並無強制要求設置，但在未來集合住宅發展埋下了勢必得變革的契機，其中造成影響最大即為我們平時極少重視的存水彎，存水彎的尺寸、大小、形狀甚至是性能都會影響建築物施工方式如降板、增築、高架等配管及設備空間設計及樓高都是施工關鍵因素，也會使存水彎設備開發商重新思考開發出尺寸、總高度較小的存水彎，故存水彎的水封深度、排水性若能及早訂定國內相關測試標準來為民眾把關，勢必更有利於跟上國際同層排水趨勢及存水彎規範及驗證的步伐。
本次研究主要為探討存水彎認證測試的不足，引出設計、實務施工常見問題及審查驗制度狀況，挑選存水彎負壓實驗及存水彎自淨能力實驗兩項主要實驗來先期引導試驗重要性，針對9組收集到的存水彎、集合式總存水彎一同進行實驗，針對存水彎的水封深度、存水量與耐負壓能力及自淨能力間的關係進行調查及分析。研究結果顯示，水封深度與耐負壓能力為正比關係，大致只要水封符合5cm後每1cm水封大約至少滿足100 Pa的負壓變化；針對自淨能力的表現，內部構造及擾流等皆會影響其自淨能力；實驗組中存水彎無效水量較多者自淨能力較弱，存水彎總存水量在350至500ml時自淨能力佳；總存水量大於1000ml時反無法存水彎自淨及耐負壓能力仍無提升；新型存水彎多數採用逆碗型、瓶型等存水彎樣態發展，因設計上入水後往四周擾動，相較於傳統單管流向的存水彎能提升自淨能力。

Same-floor drainage will be officially included in the building technical rules and building water supply and drainage equipment design technical specifications from January 2023. Although there is no mandatory requirement in the current law, it has laid the foundation for the inevitable change in the development of collective housing in the future. The biggest impact is the trap, which we rarely pay attention to. The size, shape and even performance of the trap will affect the construction methods of the building, such as lowering the floor, adding construction, and elevated construction, as well as the design of piping and equipment space. Building height is a key factor in construction, and it will also make the trap equipment developers rethink the development of smaller traps with smaller total heights. Therefore, if the water seal depth and drainage performance of the trap can be determined as soon as possible, the relevant domestic Using testing standards to safeguard the public will certainly be more conducive to keeping up with the international trends in same-floor drainage and trap specifications and verifications.
This study is mainly to explore the shortcomings of the water trap certification test, to introduce common problems in design and construction and to review the status of the inspection system. Two main tests, the water trap negative pressure test and the water trap self-purification ability test, are selected to guide the importance of the test in advance. Experiments were conducted on 9 groups of collected water traps and collective total water traps, and the relationship between the water seal depth, water storage volume, negative pressure resistance and self-purification ability of the water traps was investigated and analyzed. The research results show that the water seal depth is directly proportional to the ability to withstand negative pressure. As long as the water seal meets the requirements of 5 cm, the negative pressure change of at least 100 Pa can be met for every 1 cm of water seal. For the performance of self-purification ability, the internal structure and turbulence are all The self-purification ability of the trap is affected; the self-purification ability of the trap with more invalid water in the experimental group is weaker, and the self-purification ability of the trap is better when the total water storage volume is 350 to 500ml; when the total water storage volume is greater than 1000ml, the trap cannot be self-purified. The ability to withstand negative pressure has not been improved; most of the new water traps are developed in the form of reverse bowl-shaped and bottle-shaped water traps. Because the water is disturbed in all directions after entering the water, it can improve the negative pressure resistance compared to the traditional single-tube water trap. Self-purification ability.
