Drain Pipe Installation questions, answered by experts

If a toilet is not properly vented, you could experience issues like poor drainage, slow flushing, frequent clogs, malfunctioning traps, gurgling noises, and the release of sewer gasses. If left untreated, all of these issues could lead to longer term structural damage or (in the case of sewer gasses) harmful health side effects.

A gurgling toilet usually doesn’t mean that your septic tank is full. If waste can’t drain into a full septic tank, you’ll see water and sewage backing up into your fixtures, but the air that causes gurgling is a result of poor venting. You are more likely to have a clog in your vent stack or a damaged air admittance valve.

While some building codes allow galvanized pipe for natural gas, it shouldn’t be used for propane. Propane can cause the pipe to wear down, leading to dangerous leaks. Instead of galvanized piping for propane, you should consider coated copper, black iron, or corrugated stainless steel tubing (CSST). For underground propane line installation, you can use polyethylene (PE).

Plumbing installation in a remodel involves planning the system layout, obtaining permits, running supply and drain lines, installing fixtures, and testing for leaks.

Repiping your plumbing is when you remove the old plumbing system and replace it with newer, more modern plumbing and drainage pipes. Typically, older homes are repiped to upgrade the plumbing system. If you have frequent issues with your home’s plumbing system or live in an older home with outdated pipes, consult a professional plumber about the best course of action for repiping your plumbing.
