Unless your bathroom renovation is purely cosmetic in nature, bathroom plumbing may very well be part of your project requirements. Depending upon the age of your home, you will be working with one of the following type pipes: plastic PVC (ABS or CPVC), copper, galvanized iron, or cast iron.
If plumbing will be part of your bathroom renovation design, this would be the perfect time to replace old plumbing with new. This would avoid the possible inconvenience and costs incurred by a bathroom plumbing problem at a later time.
Bathroom renovation cost, tools, materials, time involvement, and project complexity will be determined not only by the extent of your bathroom renovation, but also by the type pipe used in plumbing.
Lightweight, inexpensive, and easy to use, plastic pipe is popular for residential plumbing purposes. Available in PVC, ABS, PE, and CPVC forms. There is also PB, but its use is prohibited in many local codes.
Available as rigid and flexible plastic pipe. PVC pipe resists chemical damage and heat better than ABS, and meets all plumbing code requirements for above ground use. CPVC withstands the high temperatures and pressure of water supply systems.
Use plastic pipe for the following purposes:
Pipe type and grade ratings are stamped on each pipe for easy identification. Please note: ABS use is restricted in some local plumbing codes.
Check with a licensed plumbing contractor, certified building inspector, or local residential plumbing code guidelines before beginning any renovation project that includes plumbing.
The best material available for water supply pipes. Available as rigid and flexible pipe; chromed copper is also available and a popular choice for exposed areas. Copper pipe resists corrosion; sweat-soldered joints are durable.
Rigid copper pipe is approved for home water supply systems by all local codes and is available in 3 wall thicknesses:
Flexible copper pipe comes in 2 wall thickness grades; types L and K. Although approved for most home water supply systems, type L is used primarily for gas service lines
DWV copper pipe is for drain systems, but is seldom used because most codes allow low-cost plastic DWV pipe.
Often the type water supply and small drain line pipe found in older homes; identified by a zinc coating and iron pipe thread fittings.
Iron pipe is strong, but difficult to cut; it corrodes with age and eventually needs replacement. Low water pressure is often a sign that rust has built up inside the pipe.
Old galvanized iron pipe systems can be difficult to work with; they are not recommended for new bathroom renovation purposes. These type bathroom plumbing repair and alterations are best left to a plumbing contractor.
Rarely used in new bathroom plumbing, cast iron pipe can be identified by its dark color and rough surface. It is strong, but difficult to cut and fit pieces together. Hubbed fittings can develop leaks, and pipes can rust through.
When the plumbing code book allows, plastic pipe replacements should be made. Use a special fitting called a banded coupling to connect new plastic pipe to existing cast iron. Cast iron pipe repair is another bathroom renovation project best left in the hands of a reliable bathroom remodel contractor.
