I am installing a new bathroom in my basement, I need to cut up concrete and install new waist line for toilet and shower. What is the best way do do this? Will I need a new vent line? The toilet will be within 8 ft. from the main waist line, the shower is about 1 ft. Thanks for your help, Dave

Why are you having to do the toilet too? It is usually pretty rare for there to be problems with the large 3" line.

Hi Dave,

Since you failed to give us many details to go on I'm going to assume that you will have a toilet, a lavatory and a shower in your basement bathroom.
Let me give you a typical bathroom rough in.
Most bathroom groups are roughed in like this.
Toilet connects to sewer main or the stack vent. Lavatory connects to toilet drain and runs a vent off the top the stubout tee out the roof or revents back into a dry vent in the attic.. The toilet wet vents through the lavatory vent and the tub/shower connects to the lavatory drain and is wet vented by it. This is a normal rough in and is acceptable both by local and state codes and also The Standard Plumbing Code Book in 90 percent of the country. Check your local codes.to make sure you're not in the excluded 10 percent.. More questions? I'm as close as a click. Tom
