The difference between a gully trap drain and a floor drain is placement. A floor drain is in a floor, a gully trap drain goes on an external wall.
Floor drain trap can dry out leaving no seal, allowing sewer gases to escape.
An S trap would go through the floor. A P trap goes through the wall. As long as the drain is below the bottom of the sink, it should drain. Distance between the bottom of the sink, the trap and the drain does not matter, it just changes how much water stay in the drain. Normally it is just in the trap, but it can be above the trap if circumstances cause the trap to be lower than usual.
If you have a floor drain, there is a trap on the bottom of that. The main line shouldn't have a trap in it. There does not need to be one on the main because each fixture should have one and that's just another place for a clog to form.
No and yes. Amendment (not from a professional plumber!): If you were simply running the sink drain into the shower drain and if there was not a reduction in pipe size, I would think you would be able to do that. I think the reason you need a trap for the sink has to do with code that requires a trap be no more than 24" from the basin to the trap arm. That being said, the pedestal sink in my house does not have a trap until after it drains below the floor.
If you can look under the sink, lavatory, or perhaps in the basement under the washing machine . . . a P trap is the drain pipe coming out of the bottom of the sink, or whatever. If that drain pipe goes down, then curves and goes up again, then goes sideways into the wall, then it is a P trap, so named because it look like the letter P if you hold your head just right and squint a lot. The other common trap is an S trap . . . it's the same as the above, except instead of the drain pipe entering the wall, it curves down, again, and goes down through the floor. Its shape is similar to the letter S, if you hold your head just right yada yada. If the drain pipe goes straight down into the floor or has an elbow, making it go through the wall, then there may be no trap at all. (Maybe: . . . the P trap for my bathtub may be found by tearing into the ceiling on the next floor down . . .)
Yes, most certainly.
Not much other than the floor slopes into a flor drain so any water or other fluid goes directly into it while a floor sink is bigger, sometimes has a strainer in it but pipes can be ended directly above floor sinks so that the fluid from the pipe flows pirectly into it
A gully trap is a way of removing waste water before it is returned to the sewer. The gully trap collects waste water from the kitchen and bathrooms.
Floor drain trap can dry out leaving no seal, allowing sewer gases to escape.
They can also require to have a self primming trap
A 3" or greater sized floor drain with p-trap doesn't need a vent providing,the fixture drain or(the pipe leading horisontally to the p-trap)is, as or longer,than 18".A p-trap lesser than 3" must be vented.
Normally a fixture trap BUT in some cases can be used as a storm or floor drain trap and it looks like the letter P
trap with a cleanout plug
An S trap would go through the floor. A P trap goes through the wall. As long as the drain is below the bottom of the sink, it should drain. Distance between the bottom of the sink, the trap and the drain does not matter, it just changes how much water stay in the drain. Normally it is just in the trap, but it can be above the trap if circumstances cause the trap to be lower than usual.
Yes... is the short answer. The toilet has a trap in itself. You would have to be able to break out the floor and put a P trap in the existing line
Wastewater from your kitchen and bathroom is piped to a gully trap before emptying into the sewer. A gully trap is a basin in the ground with a water seal to prevent foul odours of the sewer reaching the surface. Gully traps are buried in the ground with the tops or surround raised above ground level to prevent ground water entering into the sewer.
Gully Trap will prevent the back flow and stop Foul smell developed by means of all the waste point collection.
