7 Tips for Plumbing Sewer Lines

Installing sewer lines is a laborious job that requires a lot of work and plenty of time to do it. However, if you are building a home, then the sewer lines are an integral part of the waste water system. It does not matter if you have a septic tank, or your waste water goes into the city sewage system, you will need to install some sewer lines. Here are some tips to help you be a better plumber when installing new sewer lines.

1. Check Local Utility Company

Before you put a shovel into the ground it is important to contact the local utility company to check your property for under ground hazards. Even if you are replacing an old system, you should still have this done in order to know where things are located.

2. Map Sewer Line Route

Once you know where the under ground hazards are located you should map out the route of the sewer lines. This will help you to not only see where it will go, but also plan for materials you will need. You may need to have some elbows or T sections in your sewage system depending on the route of the pipes.

3. Lay Out Pipes

Lay out the pipes you are using according to your plan before you make any permanent connections. Once everything fits in place, then you can cement the pipes together.

4. Keep Proper Grade

Gravity is the best friend of a septic system. When the grade of the ground is sloping downward you do not need to have any type of extra help for the sewage to flow to the tank. If the land is level, then dig your trench for the sewer lines at a gradual slope so the waste will naturally travel in the direction towards the tank and not sit still in the pipes.

5. Install Plenty of Traps

Traps in a sewage line are important to being able to make repairs or remove clogs. These traps are small pieces of pipe that have a screw on top. Set these at various places along the sewer line so that you, or a plumber, can access the pipes to run a snake through them or flush them out.

6. Run Lines in Unused Areas

A sewage line that goes through an area in your landscape that is heavily trafficked can mean problems down the road. While a straight line is shorter, it may be necessary to install some elbows to get the pipes to circumnavigate a patio, play area, or garden. This is important if the pipes rupture, or crack. The sewage will seep up to the top soil and make for a messy play area.

7. Insulate Pipes with Rock

If you live in the colder climates of the country then you want to protect your sewer lines from freezing as much as possible. One way is to make sure that they pipes are placed under the frost line in your area. Another way is to insulate the pipes with crushed rock. Instead of placing the sewer lines on the bare ground place it on a layer of rock. Then fill in around the pipe with the rock.
