i walked into the plumbing supplies outlet and was greated very shortly by a young guy named john. i told him i needed to gut out the one shower wall and replace all the pipes behind the wall down to the basement , do to old faulty leaky pipes. he directed me over to what cvc pipes ,and sauder etc i would need. he reminded me that i would need to probably want to also put up fresh drywall to prevent mold. he was very helpful and my project went smoothly with having all the items i needed.
