It is always said that hardware is particularly important, but many people tend to overlook their significance and just buy them casually to make do with. It doesn't matter at the moment. Over time, the power of these little gadgets will show.

Take floor drains for example. How many people have encountered this situation in their homes?

I scrubbed it inside and out three times, but the toilet still smelled terrible

The floor drain in the bathroom seems to be blocked. As soon as I take a bath, water overflows like a mountain

The floor was covered with soap bubbles left over from yesterday's bath

The old stench lingers on....
