Hello,
Glad to be a new member. TerryLove.com is my go-to for initial plumbing searches. When I google an issue I always start with "terrylove.com" then my search terms.
I have a lav/bath sink drain that's begun to give me some trouble with being slow to drain, plus a gurgle. It's been in service in its current configuration for about 5 years. 1 1/2" PVC, a p-trap, 3 90s(hindsight tells me I should've put a cleanout at the 3rd one for the long run), a santee(perhaps a mistake on its back), to a 2" drain that's shared with the shower. The prior configuration was ABS with both feeding into a barrel trap. I'd like to think that I've cleaned it up for the (somewhat) better? However, the performance now isn't what the performance was in the first few years.
The shower does seem to drain as it should, and fast. The toilet, too. The sink is my concern. Keeping in mind that it is inherently flawed since it's based on an 80 year old plumbing setup. So perfection isn't my goal, for now.
[I meant, the thought of tying the sink drain into the main vent by opening up the wall and running up to it, cutting out a section of cast iron 4" pipe, etc and so forth OMG that's just nuts to consider. At that point, we'd do well to handle the tenant's bathroom above as well, since both baths were drained and configured in the same manner.(the same barrel trap setup is still up there)]
Thus far I've pulled the stopper(no clog), opened up the sink p-trap(no clog), snaked the shower p-trap through to the main drain(no clog, but that should've been obvious, but snaking in the basement standing up seemed to be more attractive activity than crouched under a sink cabinet), then (literally right in the middle of writing this) I went back to the sink p-trap, pulled it off again, and this time snaked as far as I could. When it came back it had pulled back a tiny puff of hair. I finally resorted to the plunger ... followed by a loud sucking sound! Whoa? Who knew? Ok. The drain seems to be cleared, for now.
What are some suggested options to consider for a reconfiguration that might lessen my chances of a repeat of this recent situation?
Perhaps a shorter more direct, more vertical, run into the secondary stack(pvc)? *It's 2" and services 2 sinks, a clothes washer, and 2 dishwashers. Or would the risk be too high for siphoning of the p-trap?
Simply swap out the stopper for a hair basket?
Thoughts are welcome and appreciated.
Here's what I am(and was) working with...
Old configuration showing barrel trap in ABS servicing sink and shower.
Main 4" Stack (2 Toilets, 2 Sinks, 2 Showers/Baths) and Secondary 3" Stack(Toilet, Washer, 2 sinks, shower. *Plus the 2" drain as listed above)
Newer Configuration now with separate traps for sink and shower, instead of shared barrel trap (also, the sink and toilet swapped places)
Close-up detail of santee union from 1 1/2" to 2"shower drain(probably should be a wye/long sweep?)
Detail of sink drain to shower drain shared 2" with santee on it's back(opposite view)
