Of the different kinds of metal pipes; copper, brass, or iron, which is the best to use for drainage?

The pipes are for use in a kitchen sink. I had a new sink installed, and the pipes the plumber installed keep leaking. They look like they may be copper. I want to know if he used a durable pipe material, and not a cheap kind.

If he used chrome plated brass parts under the sink the way to tell the quality of the material is to look where the manufacturers logo on the fittings are. You should see a number followed by the letters GA. This stands for gauge. In the tubular brass world, the lower the number the thicker the material. 17 GA is the best readily available, 20 GA is eh o.k., 22 GA is Home Cheapo grade and if there is no number on it it is probably 22 GA. Tubular brass installed correctly will last 20+ years. It is recyclable. PVC plastic will last long enough, but is going to eventually end up in a landfill. If PVC ever catches fire, it will release dioxin. That's why hi rise buildings use no-hub cast iron pipe for drainage.

any more, it seems like all the drain pipe I see is PVC plastic, and it seems to last forever. Historically, brass was the metal of choice. Copper and brass do split if the pipe freezes, but hold up to drain cleaner fairly well.

Pine Sap . wash and allow to soak in very hot water. Latex, Will come out with soap and water (cold water) , try pre washing first before the wash, should come out. Oil based paint is permanent - Sorry. The first two . after washing, look for the stained area, if it's still there, wash again, because as soon as you toss it in the dryer you have successfully helped the stain become permanent. Good Luck

Pine sap comes out great in any type of grease. You can buy Goop, or if you're cheap just slather on a pat of butter and rub in. Then wash normally. I've used butter quite often with great success. Paint that is dried on doesn't come out of clothing well without solvents that destroy the clothing (and you don't want the residue in your washer/dryer or on your clothes when you're done.)

If the work was just done, call the plumber and say fix this at no charge. If you intend to do the work yourself, the fastest, and cheapest material is PVC plastic pipe. You just cut to size and glue together. Any big box store has all you need and they should teach you how to do it in a few minutes. Ask for help when you purchase the material. They sell adapters to ALL existing pipes. By the way, did you find the exact source of the leak. Could it be at the connection at the bottom of the sink and drain? You may just need to tighten the connection. If the leak is small and you do not want to get too involved you can by a stop leak putty that hardens like rock and really does stop leaks. Good luck and remember you CAN fix this yourself.
