Original Air Date: Week of October 20, 2005

Plumbing and heating expert Richard Trethewey helps a homeowner improve the quality of her drinking water by installing an under-sink filter. After that, Richard and host Kevin O'Connor are joined in the loft by water-filtration expert Bill McTighe who explains several other types of residential water filters. Then, landscaping contractor Roger Cook helps a homeowner select a drought-resistant tree and plant it properly in her sloped front yard.

Installing an under-sink water filter
Richard replaces a homeowner's faucet-mounted water filter with one that mounts underneath her kitchen sink. He first breaks the connection between the cold supply pipe and the sink's faucet and connects the new filter using plastic tubing and a "T" fitting. Richard then removes a soap dispenser from the top of the sink and installs a separate faucet for the filtered water. Back in the loft, filtration-systems expert Bill McTighe shows some other options for filtering water at home.

Where To Find It
Richard installed a granulated activated carbon filter that mounts underneath a kitchen sink. It is an Ametek/US Filter BFS-201 system with CC-10 and CBR2-10 filters.

In the loft, Richard, Kevin, and Bill discussed several different types of filtration systems, including:
Brita Water Filtration Pitchers

Hydrotech 123 Series Reverse Osmosis System

Genesis Model 3000 Table Top Distiller

Sterilight Ultraviolet Water Sterilizer by R-Can

Planting a Drought-Resistant Tree
Landscaping contractor Roger Cook helps a homeowner select and plant a new tree for her front yard. They start by visiting a local nursery where they look at a Japanese Lilac, a Hornbeam, and a Honey Locust. They select the Honey Locust, take it back to the homeowner's house and dig a hole four times larger than the diameter of the pot. The homeowner's existing soil was not ideal, so Roger replaced the backfill with a mixture of loam and compost. After planting the tree, Roger installed stakes and hose-covered steel wire to guide the tree so that it will grow straight during the first year in its new environment. Finally, Roger covers the base of the tree with bark mulch and uses an irrigation bag that will water the tree for several days without a garden hose.

Where To Find It

Roger planted a Sunburst Honey Locust (Gleditsia triancanthos 'Suncole') provided by:
Mahoney's Garden Center

He then used an irrigation bag to keep the tree watered properly:
