Tea has been building continuously since the early 2000s, which means the town divides neatly into houses with passive piping and houses without. Knowing which one you own is worth about a thousand dollars, and it takes one look in the mechanical room.

What we see in Tea

Homes in the newer Heritage Parkway and Sundowner Avenue subdivisions usually have the stack. Older Tea nearer Main Avenue and the interstate typically does not. On walkout lots, the riser sometimes terminates in the garage attic rather than the house attic, which is a better arrangement and worth knowing before anybody goes looking in the wrong ceiling.

Practical notes for Tea homeowners

A passive stack is not a mitigated house. It means the house is ready. The only thing that tells you whether it needs a fan is a test after you have been living in it.

New Construction & Passive Systems in Tea: the technical part

Sloped lots complicate the loop layout. On a Tea walkout the slab often steps, and a loop laid at the deep end does not communicate with aggregate at the daylight end if a thickened footing runs between them. Either the loop crosses that footing through a sleeve set before the pour, or each section needs its own riser. Both are trivial before the concrete and impossible afterward.

What the job looks like in Tea

We look at the foundation plan rather than the floor plan, because the footings are what matter. Where the slab steps, either a sleeve gets set through the footing or a second riser goes in. Both risers can join above the ceiling later and share one fan, so a two-riser rough-in does not mean two fans.

One thing worth knowing about Tea

A high share of Tea homes already have most of a radon system in the walls. Finishing one costs a fraction of installing one.

Tea radon questions

Our lot slopes. Does that change the rough-in?

It usually means either a sleeve through the internal footing or a second riser. Both are cheap now and expensive to solve after the slab is poured.

Where should the riser terminate?

Garage attic if the layout allows. Quieter for bedrooms, keeps the pipe above freezing, and easier to service in ten years when the fan needs replacing.
