New construction

Plumbing for new construction is a specialty. Drain cleaning, and repair plumbing does not always require that you bring your existing plumbing up to and in compliance will current code requirements. If you are doing a remodeling project or building a new house, you will be required to meet all of the new code requirements.
Before you start a new construction or remodeling project it is recommended that you call a licensed plumber to give you advice on how to pick the best parts, materials, and how to lay out the plumbing that meets your needs, and meets the requirements.
Builders and general contractors usually use minimal quality parts and design consideration that will cost them less while at the same time meeting minimal code requirements. Have a local plumber or plumbing supplier give you independent usrmation on parts and floor design. It is recommended that you visit plumbing showrooms, read books, visit homes, and over all educate yourself about what is out there.
