Travel Quiz, Why Keep Hotel Restroom Door Closed? Why Balloon? #hotels
To block the sewer gas. They do not use P traps to stop the gas from venting into the room.
Lawrence is correct 90 percent, there is no P-Trap - In the USA, a house over 70 years old can be the same. When a person does his or her own plumbing, it can be the same. Yet, I think this Hotel has P traps, but we can blame it on P-traps, but this one I think is a problem of no proper venting. When the water goes done, the air must go up, or somewhere, I think the 2-3 floors below may create air pressure, and the air is somehow being released into my shower room. I can look under my sink, and see the P-trap, the owner owns a hardware also, but that does not mean they are willing to pay for the proper size stack, and have a way of running them properly from room to room, to roof. Generally, the knowledge of the 200-225 normal countries does not include the math. If you allow normal average people in the USA to do plumbing, they do the same. There is a really great reason for building permits, and inspectors, and when a contractor refuses to pull permit, well, he or she can avoid doing things more expensive, and correct.. https://en.wikipedia.org/wiki/Trap_(plumbing) https://en.wikipedia.org/wiki/Drain-waste-vent_system The question that was not answered is the balloon, I am using water balloons for fun to block the smells, but it does not work, so I shut the door, and the smells go out the window. I carry a small rubber plug, but sometime there are 2-3 drains. Floor drain, shower drains, toilets are designed to stop, and I can see the sinks. I often think that a good education in construction, plumbing, and electricity is what is needed to give Hotel reviews. I would love if more people paid attention to the neighborhoods, noise, theft, and distance to fun, and less about the colors of the rooms.
The 25 top developed countries do not share knowledge, they only sell products. Eventually, some building strategies become standard. Do they understand all the science, and technology behind it? No, but most people in the USA do not understand. One building can be built better than the USA, the plumbing better, yet, generally money rules, what we see is good, what we do not see is bad. I look on my roof, there is no roof stack maybe called roof vent, there is no 4-5 inch plastic PVC vent, maybe the vent it other, but there is no obvious vent. So, do they have a roof stack, yes, and no, depend on the Hotel. My guess is 50-80 percent of travelers never know why the toilet smells, so do not plug the drains, or shut the door. They are still using 2 inch pipes for toilet, seldom use a wax ring. The USA, Europe only sell when it is easy, and the aid organization seldom know diddle about this stuff. One aid org here is selling water purifying 5 gallon bucket things, and they sell 4 different types in the hardware. Business is 10 times more efficient than aid, but raising money for pure water is easy, so go figure...
