Of course that is why any legitimate master plumber will install a vent pitching upwards from the fixtures it is serving so the condensation will flow back to the drain or in severe cases a drip leg is installed
The Fresh Air Inlet (FAI) is where the venting system starts as it draws the colder air into the system and allows it to vent through the vent terminal
no, for health reasions,
Please re post your question. What air pipe,are you talking about the breather vent inside the wall. If you are talking about the breather vent,it is not getting sucked up it is from water being backed up in your drain,and the water can not drain quickly enough, the drain needs to be cleaned.
The minimum components are, the fixture being installed, cold and/or hot feed water, drainage or waste piping, and vent piping or air inlet for the drainage system.
By removing foul sewer fumes and venting them to the outside air nomally through the vent terminal knowing warm air rises
Without the help of plumbing vents, water and waste would not move properly through the pipes in your home. They introduce air into the plumbing system so there is no vacuum, and they carry out sewer gases which could potentially make you sick.
WHICH VENT If you're talking plumbing roof vents or soffit or ridge attic air vents; absolutely not!! I can't thing of a single vent that would be opened and closed at will.
The A/C extracts water from the air.
A vent for the drain system may be blocked. A home or building plumbing system must be "free flowing" with a vent to the outside atmosphere - usually through the roof. When water is forced down the drain and the vent for that drain is blocked, air will be pulled from inside the building through another plumbing fixture causing the gurgling sound. The main drain line may also be partially blocked whereas when water is forced down the drain the air in the drain line may be forced back into the building through another plumbing fixture causing the gurgling sound.
Provide air flow to or from drainage system and to protect trap seals from siphonage and backpressure.
The highest 4 inch pipe should have a vent on it, or directly above a toilet junction Above the flood level rim of the fixture it is servicing IT does not mean the toilet
If you are asking about flood water, yes. All transmissions have a vent to release excessive air pressure that occurs from normal heat build up. If the water reaches the level of the vent, usually at the top most of the transmission, then water can enter the transmission.
