Now there is a floor drain on the market that does not rely on water seals, nor does it rely on springs and magnets, which is very effective in preventing odors, preventing backwater and drainage. It relies entirely on the gravity of water to do this, has no odor, does not return water, and drains quickly – very wicked and odor-proof floor drains.

His washing machine has a discharging capacity, and his unique design makes the drain pipe of the washing machine floor drain closely combined with the floor drain core, and the washing machine drain will never return water

That's because your toilet and floor drain share a drain, and there is a blockage downstream of the intersection of the two, and the water cannot drain from below when flushing the toilet, and the floor drain is lower than the toilet, so it comes out of the floor drain. Suggest a solution, unblock.

There must be a blockage in the sewage pipe, so there will be backwater, find someone to dredge it.
