Drain teardown simulator
Four layers, in the order you meet them. Drag to rotate, explode to separate, click a layer to read what it does and how it comes out. Everything is generated in the browser — no models are downloaded.

This is an educational simulation of a typical floor drain, not a survey of yours. Actual fittings vary — follow the manufacturer's instructions and local plumbing rules.
2D exploded diagram
01 · Cover Plate
Holds your weight and keeps large debris out of the pipe. It is also the only layer you touch on a normal day.
Remove: Lift it straight up. Most are loose in the recess — no screws, no tools.
02 · Hair Filter
Traps hair and lint before they reach the seal. This is where 90% of slow drains start.
Remove: Twist counter-clockwise, then lift. Some push-fit models just pull out.
03 · Odor Seal
A silicone or rubber membrane that opens for water and closes against air. When it perishes, the room smells even though the drain runs perfectly.
Remove: Pull the insert out of the bore by its rim. Note which way the flap faces.
04 · P-Trap / Water Seal
A permanent water barrier between the room and the soil pipe. Water sits in the dip and blocks gas. If it dries out, gas walks straight up.
Remove: Not normally removable. Access is through the trap plug or by cutting the arm.

The teardown simulator pulls a floor drain apart, layer by layer, so you know exactly what you are reaching for before you reach for it.
