We had an S-trap in our kitchen and bathroom since the plumbing went straight down through the floor. We did a DIY bathroom remodel years ago and moved the plumbing into the wall and installed a P-trap mainly because we installed a pedestal sink and removed the cabinet. We haven't gotten to the kitchen yet, but we haven't had any issues as of yet. The house was built in 1961 and we've been here 20 years.

I am an old man and I have never had any issues with a "S" trap in my life time. As for the evaporation that would only be an issue with any drain that is not used for a long amount of time. The majority of kitchen sinks are the most heavily used drains in a house. So this is not a very common problem.

[@myopinion69420]

yeah, this is just fear mongering, trying to get people to get plumbers out to change out something that is perfectly fine in an older house. yes, if you are building a house or doing a reno, you need to put the new plumbing in to 'code', but if its already there and working, just use it unless its a problem. in some rare cases where the geometry of the S trap is just right (or wrong I guess), it can have a siphoning effect like in the images, but this is fairly rare and only tends to happen if the if the pipe heading down through the floor has quite a long drop before changing direction, general under sink to under floor joist won't be an issue. places where it can be an issue is with drains for washing machines, where they are sometimes up above countertop level, but even that is pretty rare. it is not illegal to have s-traps, or even install a new one in an existing house, eg to repair a leak or change out a sink etc. what is "illegal" (and this depends where you live) is installing one in a new build/extension, as (depending on where you live) it wont pass 'code' same way as having a house without insulation is not illegal, but you wont be able to illegally move into a new house that does not have any.

[@throttlebottle5906]

the main problem is they "can/may" syphon out, especially from a large outflow like a filled sink being drained or washing machine into laundry tub with s trap. it's not much an issue with just faucets flowing, even with GPM restrictors removed and chooching high volumes. that's my personal observation and finding over the last 30+ years. if I'm just repairing just under sink tubing, I'll leave/replace s-traps, but if replacing the whole run, I'll relocate and go with p-traps.

We put in s traps all the time in australia, amd we run single vent sewers most of the time. Not the fully vented systems ive seen in american homes. Never had a problem with am s trap siphoning unless the drain has a partial choke that effects the venting. Or improperly installed drains that are not to code. And in those situations the p traps we throw in on wall hung vanities will also siphon As will floor waste gullys or shower gullys

Probably cuz we in NZ and Australia run our residential drainage into 100mm mainline while the yanks run it all into 80mm. No need for wasting time with vents on every fixture. High rise is another story though.

In the UK we have - and I regularly use S traps, but the ones we have are deeper, and they would normally be connected into a 4" pipe. Also, all houses have a 4" stack vent (pipe) going up from the main drain to above roof level.

My home is 1927 vintage. I have an "S" trap in my basement bathroom sink. WAY too involved to retrofit it to a proper setup, so I just make a point of running the faucet slowly (maybe a 3/8" diameter stream) for 4 or 5 seconds after I use the sink to be sure the trap is totally filled. The main floor bathroom has a tub that's WAY too small for me to use (p-trap), so whenever I get up in the middle of the night for a "pit stop", I fill a drinking cup at the sink and dump it in the tub.

S traps are not the only illegal type of plumbing traps. Another type of trap that is problematic and often found in homes built before 1950, is the drum trap, commonly found in bathrooms especially with claw foot tubs. Many times they are easily identified by the clean out plug near the tub, sometimes the sink also drained into it. Sometimes the clean out is on the bottom. For one, they tend to clog frequently because they are not self scouring. Many times they are unvented. It can be difficult to get a drain auger through. And finally they tend to be made from lead which is often very brittle and prone to fracture if forced is needed to remove the clean out, it's often corroded in place.

Recently bought an older house. I was running a dehumidifier in the basement kitchen area and when it's full I dump it in the sink. A couple of times we went down there and the whole room smelled terrible ... Long story short, I finally figured out that I have an S trap under that sink with no vent so when I dumped a full gallon of water in the sink it would siphon right through the trap and let sewer gas come in the room. I now pore most of the gallon and save about a half cup to pore slowly and it's fine.

I got a question directly pertaining to this. I installed a new vanity for a customer last week, and the guy refused to let me trim inside to let a p trap fit, or to open the drywall and move the drain. The shelf inside was directly under the drain so no room to have a trap that goes lower than the tailpipe. What he did instead is he used two J bends and formed a 360° loop, and then had the tail piece that goes into the wall facing up into that loop. Hopefully I'm explaining it right. Now if you just rotated your S trap in it would look the same except that this goes into the wall instead of the floor. I wonder if this is still ok. His other bathroom downstairs had the exact same thing. I had never seen this before. I have pictures if you'd like I don't know if I can link it. After watching your video I'm semi-convinced they are just functionally S traps. Customer said it's worked perfectly fine for years.

Dear Roger, I am in an apartment built in 1954 and it seems like every time I take a shower I would smell something awful so not being a plumber myself I resorted to using chlorox bleach by first turning on the shower water then pouring half a jug of chlorox bleach into the drain then waiting five minutes before jumping into the shower. I calculate I am paying $90.00 per month in bleach just so I won’t smell the awful gases from the street as I don’t want to get sick from that. I can’t see the traps for the shower as I am in a second floor apartment and it’s in the walls so it’s all a mystery to me the plumbing. Should I call LA county inspectors to fix the problem and I have talked to other neighbors in the apartment complex and they smell the awful gases too. Could it be that the building is too old and probably the pipes along the way have corroded deep along the pathway to the street therefore making it prohibitive expensive to repair for the current owners or should I move altogether where I can live normally. I probably got a hypothyroid issue because of those gases from the past. Anyone help me please.😩

For starters, I would not pour bleach down the drain, it can react with a bunch of different chemicals and substances in your drain and cause major problems. I would call the apartment building owners and have them send someone out to inspect the pipes.

We need a “Why Heel in-let quarter bends are illegal when serving a water closet!”

[@jamesallen3739]

This is straight from the 2015 ipc study companion Lowheelinletsonaquarterbendcanbecomefloodedandthereforeshouldnotbeutilizedas wet-ventedconnectionstothedrainagesystem.Becausesideinletquarterbendsnormallydo notbecomefloodedonbrancheswithoutwaterclosetstheycanbeutilizedasawetvented connection.

Let's try that again... Low heel inlets on a quarterbend can become flooded and therefore should not be utilized as wet-vented connections to the drainage system. Because side inlet quarterbends normally do not become flooded on branches without water closets they can be utilized as a wet vented connection.

I have a trap in a utility sink in laundry room, no issues other than small leak but that’s most likely cause I installed wrong and haven’t fixed it lol

[@Clark-Mills]

The reasons the trap didn't empty might be because... * The vertical drop was too short to generate the required suction. * The volume of water "flushed" was too small. * The diameter of your trap was too large. Good work though, thanks!

Good stuff!

Glad you enjoyed it

7:00 And let's not forget, on your example S-Trap, the greater the drop, the greater the Siphon Power. And if it was made as an S-Trap, there WILL be drop, _and NO VENT!_

Also if you have a drain that isn't used you can pour mineral oil into a it won't evaporate very quickly

6:45: Wrong camera angle --- not perfectly perpendicular to the side of the trap where it would give a better view.

My bathroom is from the 80s and has a s-trap on the sink that goes through the floor and my county has no permit office so no building/plumbing/electrical permits are required.

[@RogerWakefield]

Where are you located?
