Understanding and Installing Galvanized Pipes Remove the old leaking joint. Cut the pipe with a hacksaw near the joint. Using pipe wrenches, work back to the next nearest joint, working in both directions. Check the galvanized to see if it is badly clogged with mineral buildup. If so, keep working backward until you find pipe that is not clogged.

- Spring is here and summer is going to follow quickly. That means warm air and the need to cool your home. If you have ceiling fans, they can help you maximize your air conditioning by lowering the temperature. However, that will only work if you have the fan going in the right direction. In the summer, you want the fan to go in a counterclockwise direction, also known as the forward direction. This helps drive air down toward the room's occupants. As the moving air hits the skin, it causes it to feel cooler than it really is.

Fitting Types AC fittings use a 30° flare angle, and they are most readily recognizable by a very short or non-existent straight section between the top of the thread (on the male fitting) and the major diameter of the flare. Most flare fittings of the other types have a non-threaded section at the base of the flare. NST.

Business Articles - Specialty and Trade First, although the perforated drain tile around the foundation itself may be level, solid pipe running from the foundation to daylight should slope at the rate of 1/16- to 1/8-inch per foot. Second, the open end of the discharge line should prevent entry by rodents, frogs, snakes, and reptiles.

- Click to view Vent Hole Plug Catalog Whenever fabricated steel has to be galvanized vent holes should be present to allow liquid zinc and pressure to flow freely throughout the confined spaces. If the fabricator is required to close these vent holes after galvanizing these tapered plugs are the best way to do it.

Install Your Air Filter In the Right Direction To Avoid Airflow Issues If you install your filter in the wrong direction, air will have a hard time flowing through the filter’s material and your air handler will have to work overtime to make up for the loss of airflow. This is not only a waste of energy, but it can also possibly damage your air conditioner.

Plumbing Galvanized steel potable water supply and distribution pipes are commonly found with nominal pipe sizes from 3⁄8 inch (9.5 mm) to 2 inches (51 mm). It is rarely used today for new construction residential plumbing.oday, most plumbing supply pipe is made out of steel, copper, and plastic; most waste (also known as soil) out of steel, copper, plastic, and cast iron. The straight sections of plumbing systems are called pipes or tubes. A pipe is typically formed via casting or welding, whereas a tube is made through extrusion.

Which way does a central air conditioner filter go in? Central-air-conditioner & forced-air-furnace filters are marked with air-flow-direction-arrow(s). USUALLY: Place the filter in the air-handler-unit/main-air-return-duct with arrow(s) pointing toward the fan, heat exchanger, and/or air-supply-ducts.n the filter itself, there are arrows that show the direction of the airflow. You want to install the filter so that the direction of the air, i. e. the outside air coming into the unit, is flowing in the same direction in which the arrows are indicating. add a comment.

- An air admittance valve, or AAV, is a device used in plumbing. Not every home plumbing system has an AAV, but having......he AAV is a cylindrical-shaped object with a noticeable lip made from PVC or polyvinyl chloride fitted with rubber valves. The valve is one-way, meaning that it only allows water to flow out and not back in.

Which Way Do Furnace Filters Go? When installing a new filter in your heating or air conditioning system it is important to know which way it is supposed to go. The reason this is so important is because most air filters are designed to work best when air flow is in a specific direction.nstall the furnace filter so the arrow is pointing toward the evaporator coil, blower motor and fan, which are located inside of the air handler. If the filter is being installed in a return air grill then the arrow will point toward the air handler.

Ducting / Sheet Metal Supply Air Plenums. 1  These supply air plenums are sheet metal boxes that attach to the outlet of a furnace or air handler and are used as a central manifold for other ductwork to connect to. 2  As the air blows from the furnace or air handler, it flows through the supply plenum and any ductwork attached to it. These sheet metal take-offs are designed to attach to a flat duct to allow you to connect round ducting to it. 2  They are used to attach your ducting to a supply or return air plenum. 3  Choose the size that matches the diameter of the ducting you will be using.
