Ask This Old House Season 10 Episode 8 Sink Drain, Floor Fix

In Ask This Old House season 10 episode 8, titled Sink Drain, Floor Fix, the team tackles two different projects in two different homes. First up, host Kevin O'Connor heads to Boston to help a homeowner unclog a sink drain.

The homeowner explains that the sink in her second-floor bathroom has been slow to drain, and she's tried everything from plunging to using chemical drain cleaners with no luck. Kevin starts by removing the P-trap underneath the sink and finding that it's full of hair, soap scum, and other debris. He shows the homeowner how to clean the trap and reassemble it, but the sink still doesn't drain smoothly.

Next, Kevin uses a small video camera to inspect the drain line further down and discovers that there's a clog in the horizontal run of the drain. He uses a power auger to clear the clog and then tests the sink, which now drains perfectly. With the job complete, the homeowner expresses her gratitude and relief.

Meanwhile, in Connecticut, plumber Richard Trethewey is helping a homeowner fix a sagging floor in his dining room. The homeowner explains that he's noticed the floor is uneven, and Richard quickly realizes that there's a problem with the floor joists underneath.

He works with the homeowner to remove some of the finished ceiling below and access the joists, then uses a laser level to determine the sagging sections. Richard explains that the problem is caused by undersized joists and that he'll need to sister new joists alongside the existing ones to provide more support.

He shows the homeowner how to cut and install the new joists, then uses screws to attach them to the old ones. After a bit of shimming and adjusting, Richard and the homeowner successfully level out the floor and reattach the ceiling below.

Back in Boston, Kevin heads to the home of a different homeowner to offer advice on how to deal with a common household problem: mold. He explains that mold grows in damp environments and suggests using a dehumidifier to remove excess moisture from the air.

He also shows the homeowner how to clean existing mold with a solution of bleach and water, but cautions that it's important to identify and fix the source of the moisture to prevent mold from coming back.

Finally, at the end of the episode, the team answers a viewer question about whether it's possible to install a tankless hot water heater in a home with a gas furnace. Richard explains that it's definitely possible, as long as the home's gas line and overall gas supply can handle the increased demand.

Overall, Ask This Old House season 10 episode 8 offers a diverse range of home improvement topics, from plumbing to flooring to mold remediation. The team's practical advice and clear explanations make even complex projects seem doable, and viewers are sure to pick up plenty of tips and tricks for their own homes.
