AI Video Summary: Bathroom Sink, Concrete Wall | Season 9, Episode 14 (2011)
Channel: This Old House
TL;DR
This episode of Ask This Old House features three distinct segments: plumbing expert Richard Trethewey installs a second sink into an existing bathroom vanity, landscape contractor Roger Cook demonstrates a viewer tip for easier leaf collection, and general contractor Tom Silva repairs a large crack in a concrete-block foundation using expanding foam and mortar.
Key Points
- — Homeowners request a second sink in a bathroom vanity with wasted counter space, prompting an assessment of the existing cabinet layout.
- — To accommodate new plumbing pipes, the existing full-dimension drawers are cut back to create necessary void space within the vanity cabinet.
- — The new sink opening is cut using a manufacturer-provided template to ensure a precise fit, followed by drilling a pilot hole for the jigsaw.
- — The drain system is modified by cutting a Y-fitting into the existing PVC pipe to connect the new sink's trap to the main drain line.
- — Copper T-fittings are soldered onto the existing hot and cold water lines to provide individual shutoff valves for both sinks.
- — The new faucet is installed with plumber's putty, supply lines are connected using braided stainless steel hoses, and the pop-up drain assembly is adjusted.
- — Roger Cook demonstrates a viewer tip for yard cleanup: using a cut-off wastebasket inside a paper bag to keep it rigid while collecting leaves.
- — Tom Silva addresses a foundation crack by filling the void inside the concrete block with triple-expanding foam to provide backing for the repair.
- — The crack is widened and squared off with a cold chisel to ensure the new mortar has a solid surface to bond to, preventing it from falling out.
- — Mortar is mixed with an acrylic bonding agent and applied to the crack, then textured with a sponge to match the existing wall finish.
Detailed Summary
The episode begins with a homeowner requesting the installation of a second sink in a bathroom vanity that currently has one sink and five feet of unused countertop. Plumbing expert Richard Trethewey assesses the situation and identifies that the existing full-dimension drawers block the space needed for new plumbing lines. To solve this, the drawers are cut back to create a void for the pipes. The process involves measuring the countertop to position the new sink, using a manufacturer's template to cut the precise opening, and drilling a pilot hole for the jigsaw. Once the sink fits, the focus shifts to the plumbing underneath. Since the original installation did not anticipate a second sink, the team modifies the existing drain by cutting a Y-fitting into the PVC pipe to connect the new trap. They also install copper T-fittings on the hot and cold water lines to provide individual shutoff valves for each sink, soldering them in place with care to protect the vanity. Finally, the new faucet is installed, supply lines are connected, and the pop-up drain mechanism is adjusted before the countertop is sealed with silicone caulk. Following the plumbing segment, landscape contractor Roger Cook shares a quick tip for yard cleanup. He explains that while composting leaves is ideal, many homeowners bag them for disposal. Using paper bags is better for composting than plastic, but paper bags are difficult to keep upright. A viewer tip is demonstrated where an old wastebasket with the bottom cut off is placed inside the paper bag. This rigid frame allows the bag to stand on its own, making it much easier to scoop leaves into the bag without assistance. The final segment features general contractor Tom Silva helping a homeowner repair a large crack in a concrete-block foundation wall. The homeowner discovered the crack after moving stored items, and it was letting in cold air. Tom explains that the crack is due to foundation settlement and mortar separation. The repair process begins by filling the void inside the hollow concrete block with triple-expanding foam to create a solid backing. Once the foam expands and dries, the excess is chiseled away. The surface crack is then widened and squared off using a cold chisel to ensure the new mortar will adhere properly. Tom mixes mortar with an acrylic bonding agent to enhance adhesion. Before application, the area is wetted to prevent the dry masonry from sucking moisture out of the fresh mortar. The mortar is applied, smoothed, and then textured with a damp sponge to match the existing wall's finish. Tom concludes by explaining that hydraulic cement is reserved for active water leaks, whereas standard mortar is sufficient for structural cracks like this one.
