Probably not a DIY project but a quick question about sewer lines
 

That toilet problem I had posted about a week or so ago has turned into a full blown sewer line replacement. Found a family friend who is a master plumber who gave me a nice price.

Today I came home to find that the mark ups had been done. The gas line mark up is 6 inches to the left of the sewer line mark up.

I am screwed cost wise, aren't I?

I don't understand your comment. Are you assuming that one or the other will need to be re-located? I don't know where your located, but that would not present a problem here in philadelphia on a replacement. new construction with new utilities is a diffrent story, They would need to be seperate trenches.

I am in Cherry Hill, NJ.

How do you dig a trench with a back hoe with a gas line in the way or near the sewer line? Am I required to re-route one or the other?

No, that is why they mark. your plumber will most likley locate gas service by hand untill he knows exact location and then have backhoe digg the rest. let's face its only sand where your at.

The plumber is coming out tonight to check it out.

Maybe I am worrying for nothing? I just read horror stories on the internet of people having their cost go up extensively because the sewer and gas lines were too close to each other. It's possible in those cases they were required to reroute one or the other.

If I don't have to reroute, then I guess it shouldn't be a problem.

Since they are going to dig a trench anyways, and you are dealing with a master plumber he will have the experience and knowledge to decide if you have to move the sewer over it is still just one trench. Unless you want to replace the gas line also why should it cost more to dig a trench two feet over?

I just assumed that your master has experience in residential service, some only do commercial or new construction.

you are required to hand dig until the pipes are located incase that 6" is not exact

Plumber came. The PSE&G line is 4 feet deep, the sewer line is 7 feet deep at the sewer outlet near the curb. The gas line is right above the sewer pipe. So it's going to be tough to dig the trench around the gas line.

Gonna call PSE&G and see what they have to say.

Is it not possible to cut the sewer line up near the home, 45 over and 45 back, then install new sewer in new trench several feet over and parallel to gas? You'll obviously need to "45" over and back to the old sewr near the connection to the public sewer.

Some places in the US allow all Utilities to be in the same trench with conditions.

Sewer line the lowest.

Water line above the Sewer.

Electric line on top of the water line.

You can tell why.

NOTE : same trench but staggered.

around here the locators are allowed 18" to either side of line plus half the utility,our locators really suck to put it mildly.
im guessing the digger will dig well off to the side of the side of the locate area then hand dig over to find it.
