Basic Plumbing-Basement Plumbing

The Interior Water and Drainage Installations, solve two of the basic problems of sanitation within a building. One of them comes to be, the choice of a water supply system appropriate to the characteristics and needs of each building, taking into account that its design and construction preserves water potability and guarantees its supply to consumption points in optimal conditions of quantity and pressure.

The other aspect is sewage, which is one of the main vehicles for the transmission of pathogens of epidemic-type and infectious-contagious diseases such as: poliomyelitis, hepatitis, typhoid, etc., must be evacuated. The buildings, through systems that avoid any possible risk of contamination with the environment.

The solution to the problem of water served involves the design of drainage and ventilation facilities, which must be designed in such a way that they allow a rapid drainage of the waste and avoid obstructions, prevent the passage of gases and do not allow the siphoning, escape of liquids or the formation of deposits in the interior of the pipes and finally prevent the contamination of drinking water, the diversity of problems that arise in a building and the intimate relationship that these have with health.

During the construction process of any work the sanitary installations are placed simultaneously with the other construction tasks. These facilities culminate shortly before the end of the complete work.

The following diagram is a typical Bathroom Plumbing. The drain, waste and vent system takes water away from the fixtures and out of the house.

Your bathroom vent system supplies air to the drain system to make sure waste moves out of your bathroom plumbing lines. This system typically consists of rigid plastic PVC or ABS pipes connected from your plumbing to a soil stack, which is a vertical stack of pipes that begins in the basement, where it’s connected to the outgoing sewer line.

The top end of the stack usually runs up through the roof, where it allows gases to escape outside and promotes drain flow by drawing fresh air inside. Every bathroom fixture must connect to one of your home’s main vents. It’s usually best to have a licensed professional plumber inspect, repair or install anything relating to the vent system.

Basement Basic Bathroom Plumbing

Drainage is an important consideration when planning your basement bathroom. Many basement drains don’t provide adequate fall, making natural drainage a problem. When the sewer exit point is above the level of a basement floor slab, for example, a basement bathroom will require special solutions for lift-pumping drain water to the sewer lines. Similarly, if your home uses a septic system, special solutions may be required.

Backwater Valves

In many cases, city regulations may require backwater valves on basement drain lines. These are designed to ensure that sewage flow cannot reverse direction and flow back into the home. Ask a pro if a valve is necessary with your system.

Toilets for Basement Bathrooms

Types of toilets recommended for basements

  • Pressure-assisted toilets: Sometimes even deep basement lines with good slopes aren’t enough to clear sewage in basement bathrooms. Pressure-assisted toilets use air pressure to force wastewater through the lines, which can prevent clogs.

  • Composting toilets: Composting toilets require little water and turn your sewage into compost. These designs require excellent outside ventilation but can be a good choice where it is difficult to tap into existing sewer lines.

  • Sewage-ejector toilets: Ejecting toilets temporarily store sewage and then pump it into the sewer or septic line. These designs come in both above-ground and below-ground models.

  • Up-flushing toilets: Up-flushing designs are self-contained and hook directly into existing sewer lines. These toilets are perfect for homeowners wary of breaking up a basement floor to access sewer lines. Some up-flushing models also grind waste to prevent clogs.
