|In response to Re: opening constricted galvanized pipe|
: : This old house has a 10ft piece of 1 1/2" galvanized buried in the cieling and just short of tearing out the drywall is there anything I can try pouring down the drain to open it up.If not is it safe to run a cutting blade thru it and if so what size is best..thanks
: If this is a drainage line, have it snaked with a power auger. Do NOT use chemicals like Drano. They do not work, they are dangerous to all living things and can cause damage to snaking equipment.
Thanks For the record this is the upstairs bath sink that had 2 sinks and one was taken out and a washer was installedI know its supposto be a 2 " line but not untill the job was all done.Now Im trying to avoid replacing the 1 1/2 " line.This old house also is wet venting..is that right?one vent for the whole house and it comes off the upstairs sink drainage out to the roof
