Label:Yes Color:gold,silver Package includes:1Pc Floor Drain Core Material:Brass Type:Floor Drain Core Size:4.2*3cm(1.65*1.18in)

Each core is made from Brass with a built-in seal. The compact size fits most residential drains without requiring major modifications to existing plumbing. Equipped with a floor drain backflow preventer, the core features a one-way valve that stops water, sewage, or odors from flowing back up the drain. The valve opens automatically when water drains through and closes tightly when not in use, creating a reliable barrier against unwanted smells and backups. Functioning as a shower drain smell stopper, it effectively blocks sewer odors from entering bathrooms, kitchens, or laundry rooms. To install, simply remove the old drain core (if present) and insert this one into the drain opening--no tools or professional plumbing skills needed for a quick setup. This core doubles as a shower drain stopper and shower stopper for drain; press down gently to create a temporary seal for filling bathtubs or shower floors. The silicone material conforms to drain edges, ensuring a tight fit that prevents water from leaking while the stopper is engaged. Compatible with shower floor drain, floor drain plug, and drain backflow preventer setups, it works in bathrooms, kitchens, and utility rooms. It also replaces traditional shower drain plug designs, combining odor prevention, backflow protection, and water-stopping functions in one simple tool.
