Hi All,
I was wondering about consequences of eliminating drain in floor of bathroom. Usually this is used as a checkpoint in case of blocked pipes and also to prevent return smell to bathroom.
In your opinion what do you think about that ?? should it be there or you would take it out of the system??

and in fact I would not use it for cleaning ever.
and if I have a blocked pipe I could use that machine that would work from the sink drill into the pipes to solve the problem, do you think it would work?

thanks in advance!

Floor drain in Guatemala

I've seen those in some countries while traveling, like Guatemala.
My sisters condo had that in Lebanon too.

Most homes don't have floor drains in the bathroom, it may be part of your local code, or maybe it's just an added feature, like having a seperater bidet in the room for cleaning.

If you remove it from the plumbing, you can always cable from the lav drain, or the toilet drain.
It sounds like a lot of work to remove it though.

Thanks Terry for your answer.

In fact i'm in design process and I can change it if I like, my plumper is not recommending it for those reasons:
1- the water stays in prevent sewer smells from getting back to the sinks.
2- if something blocked the pipes, they used it to fix the problem.However, I heard that we can use the machine from the sinks drain.

I would like to remove it and connect the shower drain pipe with the sink pipe then outside to the main water drain pipe of the building. What do you think ?
 
As long at the drain has a p-trap, and the p-trap is vented to prevent siphoning, it won't smell.
What country is this being plumbed for?
 
The only problem with a floor drain that is properly vented and has a P-trap, is the age old problem, that if it's not used the water will evaporate and sewer smell will come up. That can be taken care of with a cup of water added ever week or so.

Thanks for your reply!

I missed in explanations; the plumber is recommending the floor drain for the previously mentioned reasons, while I don't want to install it.

What will be your recommendation for this issue??
( this is in Egypt ).

I don't know how your plumbers plans to configure the pipes, so it's hard to say what it will do, or how well it will work when complete.
It seems to be the custom there, where floors are made of concrete and tile, and the tile is washed down often. The floor drains are helpful for that.
My sister did mention that sometimes, (She noticed it in the airports) there are no P-Traps under things like shower pans, and it can smell pretty bad.
In the USA, any floor drain would have a p-trap, that would hold water in the lower part to prevent the air from entering the room from the piping system.
 
you are right Terry, it is the custom here. we don't use the p-trap under the shower cabinet drainage, so the floor drain could help to prevent the coming back smell from going in. However, don't you think that installing one gully-trap on the main sewage pipe outside the building downstairs would prevent the smell from coming back from the main sewage manhole?
 
Here we used to use a house trap and many areas still require them...

Then people figured out their own poop smelled and put traps on all fixtures. The water in the trap holds back sewer gas and odors.

One would think that with traps on all fixtures that you would not need a house trap.

However...

My neighbor was having trouble with sewer backups at his house and dug down to find an old house trap that had corroded badly. It was flowing slowly so he removed it. Everything flows great now, but now when the wind blows right you get a nice whiff of sewer from the vent stack. Blech!
