[Shop-talk] Fw: an new one on me... plumbing

[john niolon]

We have a standard three br/2 bath house with 4" pvc sewer plumbing... no 
problems in 15 years... septic tank has been cleaned out three times in that 
time (health dept rules for a bakery business in the house)

I'm redoing a bathroom (had to remove toilet) it's across the wall from the 
laundry room.  I noticed while working in the bathroom that when  the washer 
drained ...the suds from the washer came back up through the toilet 
piping...cleaned up the mess and thought it was just cause the pipe was 
open.

later after reinstalling the toilet...when the washer drains I get heavy 
bubbling in both toilets now... never seen that before...  both toilets seem 
to flush well and no other problems with sinks in kitchen, baths or 
bakery...

I'm brainstorming here (not a lot of thunder and lightening in that storm) 
and wonder if it might be a vent problem ???  or an obstruction in drain 
pipe ???   washer never overflows or caused any problem before...

watyallthink ???

thanks
John
