Straight seed consists of only one type of grass and is suited to situations where you want to achieve a certain look or effect. Blends (several varieties of one type) and mixtures (combination of different types) offer better disease resistance and a uniform lawn.lended Seed Mixtures: Blended seed mixtures combine several different kinds of the same grass species to capitalize on the strengths of each type. By using the same species, you can ensure a more consistent appearance to your lawn.
In new construction, the plumber will install a separate vent for any plumbing fixture that does not use the vanity vent. If a fixture has its own vent line, the line will run vertically to the attic and tie into the vent-and-soil stack if possible. If not, a separate roof exit is necessary. Alternately, the vent pipe can exit the home through an exterior wall, with the opening covered by a vent plate.
A direct vent system is a very efficient alternative to a traditional gas fireplace. Direct Vent Fireplaces are factory built and their venting can be routed directly through a wall to the outside, using rigid or flexible venting. Direct vent systems are either co-axial (as stated above) or co-linear; Co-linear Direct Vent Fireplaces are used to vent through an existing wood burning chimney.
