The sink drains down into a P-Trap and then enters a 1 1/2 inch PVC horizontal drain line that runs into the wall. Due to some blockage issues in the immediate area under the sink I'd like to run that horizontal drain line 3 feet before turning downward. Would this be workable?
Also, if this is workable, does the 3 foot horizontal run remain level or should it be biased before turning downward?
Thanks.
