|In response to Re: maximum drain slope|
: i recently replaced most of the plumbing in my kitchen. when i did, the "T" in my kitchen drain had to be replaced at a slope greater than 1/4" per foot due to other obstacles. it now has a slope of appoximately 4" per foot. it used to connect to the vent pipe about a foot or so higher than it does now. could this be a reason for a very slow-running drain? running the water for more than 1 minute forces it to back-up into the sink. i'm going to snake my vent pipe, but should i be looking at this slope as a potential problem?
