The Ultimate Guide to Plumbing Codes

When it comes to plumbing, it is one of the most complicated tangents of any bathroom revamping. One mistake and it can lead to a disaster! Hence, while you opt for any plumbing related work, there are some codes (source) you should conform to for safety reasons.

Following the national plumbing codes that apply to the whole country is a must. But, while on a plumbing spree, you should also follow the local codes, as they are more strict and precise. Always get your plans approved by the registered authority and commence it only under the guidance of the respective inspector. This helps in building protective measures and precaution against any mishap.

Today, we shall be covering some basic common plumbing codes, let’s begin –

  • Make sure that the fixtures are not placed closely. This is a major situation in any bathroom, where spacing is necessary.
  • Before starting with the plumbing procedure, always determine the accurate sizes of the pipes for supply lines, vents, and drains.
  • Make sure of the pipe material you are using. Mostly, copper pipe is preferred for supply lines whereas PVC (info) is preferred for drains.
  • Another important thing to remember is that the home structure should not be weakened in this entire process.  Make sure to support the joists which were initially cut to fit in the pipes.
  • Always use fire caulking around pipes, this will help prevent the fire from getting through the cracks of buildings.
  • Place protective plates, commonly known as a stud guard (source) around the pipes.

Other Major codes to be kept in mind –

  • Determining the correct slope of the drain pipe is very important especially when the room where the drainpipe is running from does not have a basement. The slope depends on the plumbing code of the area.
  • While using PVC pipes, try using purple primer instead of glue. This not only helps the inspector judge how firmly the pipes are joined but also prevents leakages.
  • Always install cleanouts for an easy cleaning mechanism when the drains are clogged. In the absence of a cleanout, it becomes very difficult to get rid of the clogged drain. In worst cases, severe blockage might lead to a completely new plumbing system. If there is a drain cleanout nearby, this step can be skipped.
  • Consider checking for leaks once you are done with installing the pipes. Generally, the inspector checks leaks by casually pouring water down the pipes. Make sure the pipes are intact and no chances for a leakage are left behind.
  • In most cases, the valves, cleanouts, fixture controls, etc. are covered behind a wall or under the floor surface. This need not be done if you want to access the system in the future. For this, install an access panel somewhere, where it is not permanently covered, most likely behind the tub.
  • Using approved clamps/straps is mandatory. According to most codes (source), PVC pipes should be supported every 4 feet, iron pipes every 5 feet, copper pipes every 6 feet, and black steel pipes every 12 feet. These codes can differ according to the area and type of the pipe’s material.

These were only some commonly followed plumbing codes that everyone should keep in mind while the process. However, there are more codes which you should consider according to the place where you reside in for better functioning.
