It doesn't really matter. I usually put the female half, the side with the nut on first so I don't forget to put the nut on the pipe before I put that half on the pipe.
The pipe installed for the purpose of ventilation is known as a vent pipe while a pipe which is installed in a house drainage to preserve the water seal of trap is an anti-siphonage pipe.

Drip cup should be 2 and 1/2 times the pipe being served. Check local Gas Code bylaws for proper information.
You carefully cut the pipe, then if you can push it apart enough to fit one nut and one'olive on each end of the pipe. Now seat both ends in the union. At this point you hold the centre of the union with a wrench and tighten each end nut while pushing the pipe in towards the union. When both ends feel tight, hold each end nut with a wrench and give one final 1/4 turn. That was with a standard brass union, now you can also fit a 'sharkbite' with no wrench, just firmly pushing each end in. With 'sharkbite', however you MUST make sure the pipe ends are smooth and have no sharp edges.
You should use black pipe -- Galv. pipe will flake off inside of pipe

Yes. Allsorts of debris, nests, critters, etc., can accumulate in a pipe before it is installed. If the pipe is to carry potable water, it should be a free as possible of that stuff before being installed.
Nope, should be 4" to prevent hoarfrost
There should be no more than six inches between CPVC pipe and the exhaust flue on a water heater. If the CPVC pipe is installed too close it can be a safety issue.

The meter has to be installed on the exterior using black steel pipe in the home.
Start with one of the pipes you are connecting together. I usually start with the female half of the union. The half that has the nut on it. Slide the nut over the pipe first so you don't forget it. Use pipe dope or teflon tape on the threads of the pipe. Screw on the female half of the union and tighten it with two pipe wrenches, holding the pipe with one of them. Put the other half of the union on the second piece of pipe you are connecting and tighten it. Now bring the two halves of the union together and screw on the union nut. Do not put any pipe dope or tape on the union itself. It is a dry fit. Tighten the nut while holding the male half of the union. The second half of the union. -- I always put pipe dope on the union, it helps the union tighten more and it helps keep the threads from corroding together over time, making taking it appart easier.

A stink pipe, or vent pipe, should be installed vertically and extend above the roofline of the building to effectively vent sewer gases outside. It is typically placed near the main waste stack, ideally within 3-5 feet of the fixture it serves. Ensure it is installed in a location that avoids obstruction and is easily accessible for maintenance. Local building codes should also be followed for proper installation and placement.
No. Some old-school plumbers and pipefitters believe that unions should be installed in one specific direction, and some apprentice training books even say so, but this is only a bit of folklore that has no basis in fact. Anvil International, the maker of most steel pipe fittings, has an illustration http://www.anvilintl.com/ProductSearch/ProductInfo.aspx?ProductId=9960 of an assembled union which shows no internal impediment to flow. Nowhere in any of Anvil's product literature is there any installation instruction regarding flow direction. Control valves and check valves, which do have directional requirements, have flow arrows stamped onto them, but unions do not. Additionally, the circuit setter valves (such as those made by Bell & Gossett) with union ends are installed with the union end facing opposite directions relative to flow (i.e., male end upstream on the return valve and male end downstream on the supply valve).
The sump pump discharge pipe should be directed away from the home's foundation and towards a safe drainage area, such as a storm drain or a sloped area that leads away from the house.
