How to redistribute bathroom plumbing

The great thing about remodeling bathrooms is that often results in an increase in the value of your home that is higher than the actual costs of remodeling. If you want more space or want a new pattern of traffic in the bathroom, one thing is inevitable, the need to relocate the pipes. Before you start buying accessories, make sure your new plan is viable.


  1. Determine the configuration of the new bathroom to suit your existing drainage system. While it is possible to move almost any large appliance under the bathroom floor joists that are supported should not be cut in order to install new drains. Design your new settings for new drains running parallel to the joists and between them.
  2. Determine setbacks accessories. Refer to the first local building code, if necessary get a permit to remodel the bathroom, you’ll probably have to stick to the adjustment measures. This only means allowing enough space on all sides of the main apparatus. Follow the standard code if the local code is not available.
  3. Provide future access panels. Although the plumbing is generally accessible for sink in the cabinet under the plumbing and bathroom requires only lift the toilet floor flange, it is a different story for pipes for shower. There could be a problem with your bath or shower pipe; the only feasible access is often from the next room, hopefully in a closet or discreet place. If there is a side wall in the bathroom, the access panel plans there.
  4. Close the water supply before you begin, it is usually located in a utility room. Some older homes have only a meter outer closure. Remove accessories and off the water feed and drain. Cover and seal all power of ancient water. You can press the copper tubing or buy special plugs PVC pipes.
  5. Install your new water sources, bringing the hot and cold water directly from the bottom, between the uprights. Prevent feeders run horizontally or drilled through the posts. Tie the old system if you have sources of copper or PEX piping runs if you have a port new compression system, as MANABLOC.
  6. Allow proper slope in the sewer system. The minimum slope for drainage of waste is a fall of ¼ inch (0.64 cm) for every 4 feet (1.22 m) of linear drainage tube. In a sink drain, you need at least one tube of 2 inches (5.08 cm), a shower also requires a pipe of 2 inches (5.08 cm), but the bathroom needs a larger 3-inch pipe (7.62 cm) to 4 inches (10.16 cm). Avoid using a slope greater than recommended for a bath, to prevent liquid run out of the solid waste in the pipeline.
  7. Your feeders need to be pressurized with water before placing new accessories. To crown it all the ends of the pipes of cold and hot water and cover the drain. Turn the water source and allow the tubes to be filled with pressurized water. Leave pressurized pipes for a few hours and check for leaks before placing the accessories and hardware installation.
  8. Place the new devices and connect the feed water and drains. Make sure the hot and cold sources are correct when installing the taps. Check for leaks around faucets and reset if necessary.
