Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of drainage systems, it is recommended to prioritize checking key technical parameters such as drainage volume, pressure rating, and interface size to ensure compatibility with existing pipeline systems.
  • In industrial plants or underground garages that are prone to water accumulation, the anti-corrosion performance and automatic opening and closing function of the drain can be considered as key evaluation dimensions.
  • When selecting suppliers, reference can be made to product compatibility, business qualifications, enterprise activity, industry performance, and platform statistics to comprehensively screen long-term stable partners.
  • For different drainage media (such as oily wastewater or ordinary rainwater), it is necessary to confirm the material compatibility of the drain, such as the applicability differences of options such as stainless steel or PVC.
