Radon Sump
Radon sump
The use of a radon sump is presently considered one of the most efficient methods of extracting the radioactive gas laden air from the ground floor areas. The efficiency of a radon sump is so high that after its action, the level of radon drops to one tenth of the original amount; moreover, the radon sump is easy to install for both solid and suspended floors, with the only condition that there be a concrete layer covering the soil. The working principle behind the functioning of a radon sump is in fact the de-pressurization procedure on which it relies. The installation of a radon sump is not difficult, but it usually requires professional training so that the functionality is 100% appropriate.
The radon sump mainly consists of a cavity not larger than a bucket located under the floor slab, but in direct contact with the underfloor hardcore. This hole or cavity is linked to a network of pipes that lead to the exterior of the house. What the radon sump actually does is a reversing in the difference of pressure between the area under the floor and the room above it. With the help of an electric fan included in the structure of the pipeline, the random sump prevents the radon-laden air from entering the room, and evacuates it through the pipes towards the exterior.
The choice of the radon sump is very important, since it has to perfectly adjust to building size and design. Therefore, you will need an expert's advice on the matter, or you risk to cause extended damage to the overall home system structure. A careful check of the area affected by radon will enable a pro to provide pertinent information on the right radon sump size. If you order the device on the Internet, make sure to check all the information in the product review and confront it with what you've got on the label after receiving the sump.
Last but not least, the use of a radon sump will slightly increase your electricity bill, due to the fact that the fan that evacuates radon in the pipes requires 75 watts power. This is almost the same type of power specific to a regular light bulb, with the mention that the radon sump will be running all the time. The fan is designed to last for at least five years, and only then you'll need to have it replaced. New, the fan for the radon sump is around $120, to which you may add the installation costs as well.
