Common Plumbing Code Violations
Plumbing Codes can be pretty complex which is why it’s a good reason to go with a professional plumber for any kind of plumbing work, but if you must install plumbing systems yourself, you have to make sure you’re up to code. Here are a couple of common plumbing code violations
Improper pitch can allow for leaks and/or a slow draining of a sink or bathtub. Drain pipes need gravity to properly empty water towards the sewer. Standard practice calls for drain pipes to have 1/4 inch per foot pitch. 1/3 inch per foot is allowed if the drain pipe is 3 inches in diameter or bigger.
Not Enough Toilet Space
There needs to be at least 15 inches of space between a finished wall and a toilet. To measure this you go from the toilet centerline not from the outside edge.
The number of clean-outs needed depends on the size of the system. According to the IPC, building sewers shall be provided with cleanouts located not more than 100 feet apart, measured from the upstream and trends of the clean-out. Clean-outs also need to be installed at each change of direction greater than 45 degrees in the building sewer, building drain and horizontal waste or soil lines.
Clean-Outs in Wrong Places
Should be placed in a way that they won't be covered by casements, cabinets or machinery. cleanout should avoid places that have food, computers for critical areas, like an electrical junction.
Installing Improper Fitting for Changes in Direction
Change of direction in pipes must be done with fittings that will not cause any obstruction in flow.
Remember plumbing codes are complex, the best option is to get a professional plumber, but if you're going to do it yourself be careful and take all the right steps to make sure you do everything properly.
