You may or may not need a plumber to tighten the drain pipe to stop this particular leak, but what if that drip were behind the wall in your kitchen or bathroom, or behind a refrigerator or washing machine, where you may never see it until the water damage is so great it begins to grow mildew inside the walls causing a distinct odor in your room or entire house.
One who fixes or repairs pipes. Plumber has a "b" in it because pipes were originally made of lead, (lead seemed a logical choice at the time, because of its resiliancy against rust... then people discovered what lead poisening was, and rust no longer seemed so bad!) and lead's abbreviation on the periodic table is pb (derived from its latin name).
I was disappointed with the pressure of a tub and shower that were plumbed with 1/2 supply lines (2nd floor). Could be low pressure from the street, but I want to replace with 5/8. Plus, I'd like to have 2 back to back showers, one inside and one outside. So, I had intended to bring a 1 supply to both, then branch up to valves and shower head with 5/8. Finally, I thought pressure from the street was typically 55 to 70 psi and I am concerned if pvc can take that.Any thoughts?
