Keep Water Out of the Basement
Project: Basement Finishing and Family Space, Episode 2, Part 1
Bob and Larry Janesky of Basement Systems review the work being done to cut a drainage trench in the concrete around the perimeter of the basement floor. Water will be channeled through the trench to a sump – dug at the lowest spot in the basement – where it can be pumped out of the home. A triple safe power pump protects the home even if there is a loss of power. Bob reviews the work done on the existing plumbing once all the waterproofing and flood-prevention measures are put in place in the basement. Al Leone of Leone Plumbing Corp. first cut the pipes into sections for easy removal and demonstrates some of the specialized work he does to install the pipe, including using oakum, a joint runner, and poured hot lead to form a joint seal. Old brass water pipes are replaced with PEX tubing, creating more headroom in the basement and the sink and laundry lines can be easily relocated. Bob talks with Dan Driscoll of Rinnai about the new on-demand water heater being installed. The heater is a whole-house system sized for a three-bathroom household, laundry, and cleaning. An on-demand, tankless water heater saves basement space and is energy efficient because it does not store hot water. Driscoll opens up the water heater to show how the system works. Once the water is turned on, sensors detect the amount of water being used and the temperature of the incoming cold water. The on-demand system is about 40% more efficient than gas-fueled tank water heaters and 70% more efficient than electric tank water heaters.
- Part 1: Keep Water Out of the Basement
- Larry Janesky of Basement Systems reviews the work being done to cut a drainage trench in the concrete around the perimeter of the basement floor. Water will be channeled through the trench to a sump, where it can be pumped out of the home. The sump hole was dug at the lowest spot in the basement as determined by laser level. CleanSpace is being installed over the walls as a vapor barrier to drain water from the walls to the drainage system. It is possible to install CleanSpace in crawlspaces as well as in basements to prevent water buildup in underground walls and eliminate rot and mildew. Janesky recommends taking these two steps in securing the drainage of a home and to secure against all outside air leaks. The final step is to dehumidify the crawlspace. Janesky points out a corner of the basement where the Thermal Dry Wall System has been installed. This product goes behind finished walls and drains water like CleanSpace but also reflects heat generated in the basement back into the basement. Janesky then shows a portion of the floor where the Water Guard Drainage System has been installed in the drainage trench and secured with cement.
