This is the wrong way to install a vent the vent should terminate 13 inches above the flood level of the sink.This information is from a master plumber
When was the original installed??.. if before no S traps allowed -it is legal. No code ever says to go back and update any system installed under a prior code or no code. You only have to meet the current code on anything installed at that time.
The problems I've had with S-traps were not caused by lack of an air vent. Instead they are caused by the S-trap requiring drain water to go too high back up before turning back down. This means if the lower trap clogs, removing the trap will release quite a lot of water more than what is in the trap. Plumbing can be quite unpleasant to deal with.
Good info. Thanks! One question... you, and others, say these AAVs wear out and may need to be replaced from time to time. How would one know if their AAV is not functioning properly, or is worn out?
Don’t take the distance-above the Tee as being gospel. Check your local codes to ensure that distance above is above-flood or above-tee. You will fail inspection and could have problems filing insurance damage claims for overflow flooding if not done properly.
If the vent pipe doesn’t have an AAV on the end of it then you’re supposed to have it vent above the roof so any sewer gases are not going into your home.
Wait a minute? You're advocating this is a fix? Looks like you're doing a pretty extensive rehab. You have the walls open seems you're in the basement as the pipe terminates to concrete so you have access to this vent, but failed to connect to it through any and all means. You're leaving the ferco tee which appears to be inside of wall. where is this 4 inches that you mentioned coming from at least 4 inches? you need to be 12 inches above the rim of the flood zone? Which in your case is top of your washing machine trap arm which absolutely needs to be 2 inch in size you will not like the results of leaving that vent in that location where you're clearly draining the washing machine above the point of vent… your washing machine is going to discharging! Out of your vent!!!!….. DoDYI

Those vent valves dont need to be above the flood level at least in my area, most manufacturers just say a minimum of 5 inches above the tee.
@@jacksplumbingvideos7147 my code says 4" above the tee.
Not a lot of space above the vent to unscrew if you ever needed to replace the unit from what I could see in the video.

Not always true… if just replacing the trap, maybe. If remodeling - must meet code!!!
My house has several grandfathered s traps and no issues

If you start smelling sewer gases, then it means it aav isn’t blocking them anymore and you should replace it

It can every where else in the world America must have different water to rest of us
Very helpful thanks. If one instead used an open external vent pipe, what's the minimum height it needs to run to please?

When you say "illegal", do you mean illegal in CA?
An s-trap is no longer legal in the USA
@@legolwa"legal" lmfao

It's not illegal.... The vent must be 6" above sink!!
