Plumbing Codes That You and Your Plumber Should Know


One of the most important issues related to plumbing codes has to do with ventilation. Proper ventilation allows your pipes to run efficiently and prevents toxic fumes from entering your home.




Fixtures are another important issue related to plumbing codes. Plumbing fixture should not be placed too close together. This is especially important to remember in smaller rooms in your home such as bathrooms where space is limited.




Another important consideration when it comes to plumbing codes is the size.  Plumbing codes determine the right size for vents, drains, and supply lines.  In plumbing, size does matter; it can effect many things like water pressure and noise, among others.


Proper Materials

Another key element of plumbing codes has to do with using the proper materials when performing plumbing services or repairs. Most plumbing codes will require plumbers to use copper piping for supply lines and PVC piping for drains.  Pex, when used correctly, is often allowed nowadays, as well.


Water Pressure


The water pressure in your home is also very important. If pressure isn’t just right it could cause problems in your home. If the pressure is too low you may need to invest in a pump to boost the pressure. And if the pressure is too high, your plumbing professional might need to install a pressure reduction valve.


Structure of Home


Plumbing services or repairs must not compromise the structural integrity of your home. Sometimes plumbing codes require you or your professional plumber to reinforce joists or to install protective plates over pipes.


Drain Pipe Slope


Plumbing codes require that drainpipes must slope at one quarter inch per running foot. Code also mandates that vent pipes slope at one eighth inch per running foot of pipe.  These stipulations keep everything flowing correctly, and help reduce back-ups.


Priming of Pipes


Plumbing codes also require all pipes to be primed. A certified licensed plumbing professional will use purple primer to do this so that it easy to see that pipes have been primed and are in compliance with codes.

These are just a few of the considerations related to plumbing codes that are crucial when your plumbing professional is performing plumbing services or making plumbing repairs in your home.
