Underground plumbing - DIY Series

Remember, once all the walls are up and the foundation is finished, it is difficult to go back and add plumbing elements later; be sure to take your time during the planning phase; otherwise, you will experience a lot of headaches later. If, for example, you want a pool a few years down the line, accommodate for that plumbing now.


Once a list all the necessities and extras is made , you will go through the bidding process for a contractor similarly to the other contractors you have needed along the way. When the selection portion of the process is complete, it is best to meet with your contractor face to face to discuss the project in detail and firm up completion dates as best as possible.

The plumber you contract will need to install the underground plumbing once the foundation walls are up. These installations must follow strict local and national codes and guidelines, so prepare for this during the inspection process. The scrutiny of such installations is in place to ensure the occupant’s  and the environment’s safety.

Water wells are used when there is no access to a town or city water supply. There are stringent Environmental Protection Agency (EPA) rules governing the distance and location of wells and septic systems from each other. Be sure the contractors chosen to dig the well and run the transport pipe protects them from freezing by placing it all below the frost line.

When researching contractors, be sure they are members of the National Ground Water Association (NGWA); this shows their dedication and professionalism. Other designations include Certified Well Driller (CWD), Master Ground Water Contractor (MGWC), and Certified Pump Installer (CPI). These certifications will prove consequential when it comes time for the inspection.

It is a good idea to install water filtration for well water and a municipal supply on the main waterline as it enters the house. Water filters have been proved to remove sediment, lead, dust, sand, silt, sulphur, dirt, excess chlorine, and other contaminates. Filters also reduce the water’s odor and can improve and can improve the taste. Installation during construction protects pipelines, equipment, and appliances from harmful elements the water may contain. This measure is optional, unless a water treatment tests prove otherwise, so do not worry if you do not have enough room in your budget for this installation. Water filters can be safely and successfully installed later.

When the inspector comes to ensure that all the work meets code, they will also check to be sure all the waste lines are properly sealed. The septic system is usually inspected the same time as the rest of the underground plumbing. If you have a private septic system, it is absolutely essential to hire a reputable contractor to install the waste system so all the codes for your municipality and the EPA are met. Once all the areas of inspection have passed, you or the contractor can fill in all the trenches.

Remember, plumbing is an important part of the planning process. It is crucial to know what you want and where you want it to be. It is extremely tough and expensive to go back and move lines around or add things in if it is not done right the first time. Be sure to take your time, discuss these plans with others, and ask questions of yourself as well as any other occupants of your house.
