Home Inspector Atlanta GA Reveals Another Plumbing Vent Gone Bad

[shauntampa]

hello, another hack job.

[plumber8484]

a studor vent would not work on that pump because a studor only lets air in. when the water starts to fill in the pump the air has to go some were and with the check valve with all that water weight on it it would not push through the check vale the vent would need to be terminated to the outside like it should be. a studor WOULD NOT WORK. trust me ive seen it before it does not work with a studor vent

[zihcm]

the check valve will keep gas out

[albert9251]

Any Plumbers here put a studor vent on a ejector? Man OOhh Man

[xxx777aaa]

@albert9251 it may work but NOT THAT CLOSE TO THE DRAIN! I WOULD HAVE A MINIMUM AT LEAST! DEFINITELY NOT BELOW THE DRAIN PIPE ITSELF..THAT WOULD REALLY TEST THE CHEATER VENT AND YOU MAY GET A GUSHER!

"Studor" vents are illegal on pump receptacles.

The are air admittance valves used to prevent siphonage that breaks the trap water seal. Air must exit the tank, and studors will not allow it. No easy fix here, as vent should tie into vent system, or outside.

Good call

I don't think air needs to "exit" the tank, air needs to "enter" the tank to prevent collapsing of it but more importantly it needs to draw in air to save the trap seal. The pump will create a negative pressure that will siphone the trap with it but if you introduce atmoshperic pressure(fresh air) it will prevent the siphone. The Studor diaphram will open when the pump runs but yeah, no easy fix. Tie it in or go outside with it.

Air must exit the tank thru a vent- when a toilet is flushed, or a sink is drained- the tank pressurizes and prevents water from flowing into it. The only other tank outlet is the pump pressure pipe, which while at "rest" has a check valve with a column of water above it.

@Splungers your are exactly right. im glad someone has there head on straight

[plumber8484]

@PLUMBdogg air must exit the tank when the water enters the tank it doesnt start pumping right away it must fill to a certain point b4 the pump turns on. so ther must be some displacement of the air in the pump
