Sometimes the sink in the garage has a sewage smell coming up out of it, I though a P trap was supposed to stop that from happening but I am kind of ignorant, is there something really fucked up with this setup that you can see just from this?
>>3007461That's an S trap. Fine 99% of the time for over 100 years, but occasionally can get sucked dry if you have shit venting on the rest of the system.
>>3007463So somewhere down the line in the connections there is either poor or not venting and that is causing water from this trap to just get sucked down instead of sitting still?is there a simple way to diagnose such a thing? There is a really poorly DIY bathroom setup in this garage on a platform with the sink, toilet, shower, and washer all within 10ft of each other and the water heater
>>3007465>>3007461I'd say it's scum collecting in those accordion traps. You can just put a flashlight to it and see if there are clogs visible. Although I have no idea on pipe venting.
>>3007466If it was a mild little stink it would be one thing but it's sewage smell, the same smell you might whiff at the street sometimes, and when it comes through the stink hits the whole garage it is very easy to tell when it is or isn't happening rather than just something collecting
>>3007461>>3007463first post is probably right.it needs a vent.you can cut that 90 off put a tee and stick an auto vent on a bit of pipe coming out the top of the tee to raise it up a bit
>>3007474When you say cut the 90 etc do you you mean replace this part so it looks has a port pointing upwards like a sideways T and install that on top?
>>300747845 seconds in drawing app on my phone.Does it make sense?
>>3007480I realizes I drew it as a P trap instead of an S trap like you have, but don't worry about that.
>>3007478>>3007480heres how i would do it
>>3007482forgot pic
>>3007483u know this is probably why anon should have just asked AI desu
>>3007480>>3007478>>3007481>>3007482Yeah that is what I figured you meant, but since I am super ignorant when it comes to plumbing etc, is that autovent just goint to vent farts into the garage in the same way, just potentially less often or?
>>3007486na they are spring loaded with a seal, the point is that they will let the system vent without sucking the trap dry and also not letting shit stink through it cause that would defeat the purpose.they can go to shit over time but its better than no vent or having to run a vent somewhere else.
>>3007463S traps don't work, period. Some retarded boomer came up with this shit and other dumb boomers copied it.
>>3007483seconding this, so many less seals that could go wrong
>>3007535Nice facts to back up your assertions there fella
>>3007483That doesn't really look up to code
>>3007463Either this, or the water is evaporating. How often do you use that sink and how hot does it get in your garage?
>>3007535>periodMuch confidence. So wrong.
>>3007535You ok dude?
you should also replace the accordion drain with straight pipe, its known to trap all sorts of shit
>>3007465>is there a simple way to diagnose such a thing?when you smell it unscrew a side of the s trap and see if the water level is low>now you know.how to fix it?replace the 90 going to the p trap with a sant and top with an air admittance valvethose dude wipes are gonna clog your shitty diy drains too. >>3007483>>3007621the only problem with this is the t fitting is incorrectyou want a sanitary t for drainage
>>3007480Wait, wouldn't you need the vent after the S trap, not before it? With this drawing you'd just have two air inlets on one side of the S trap to just siphon the water faster, right?
>>3007663yes his drawing is retarded, do the ai anons thing here >>3007483but with these t's >>3007650make sure you put it the right direction.you need a 1 1/2" trap kit, a san t, a coupling, like 3ft of 1.5" abs, and an auto vent.
>>3007461that u trap is in the wrong place, no wonder your sink smells
>>3007461Wtf is that? Landlord special?
>>3007461Check if your cleanout (the place where all the pipes lead, I dunno if I called it correctly) doesn't have another hole at the bottom that lowers the water level and let the air enter. I'm having this shit rn but I'm a rentcuck so nothing I can(and will) do.
