One down, one to go. The slow drain is working like a champ now. I took the drain apart, snaked it out. Put back together, ran vinegar, baking soda and boiling water down it. Glug, glug, glug......better than ever!!! Going to tackle the downstairs sink in a bit. I know it will be more problematic, I shut off the water to the sink (its in a rarely used bathroom) before we left this last time around, found it was leaking pretty badly. Cleaned it all out and now to tackle the leak!! I will ascertain where its leaking first and foremost. (thank goodness for shutoff valves)
