Q:1/8 the trachea needs an outside diameter of the trachea
1/8 for 3.2 mm OD, you choose the trachea, then should look at the trachea is the diameter, not the outer diameter, generally as long as less than 3.2 millimeters in diameter, the tube OK. But don't be too small to avoid getting in.
Q:What decides if a fire is 1 or 5 alarm?
I know what your seeking but recently here in NZ its been banned because of the fittings blowing off the crimping isn't sufficient, co's over time it corrodes away, allowing the pipe to blow off! It's a bugger if it's in an interior wall. Here there's another brand and it has a stainless steel bush pushed up inside each connection before the fitting is pushed on. These fittings are able to be undone if needed they come in all sorts of sized configurations (it used to be called Acorn fittings but it could have since changed) The only thing is I wouldn't expect this plastic piping to carry hot water. The blockage might be something simple you will just have to try and eliminate possible causes by checking everything. The problem could quite easily be the pressure reducing valve as they often gum up with crap besides they have a tiny jet within them that blocks if the diapham is perished then you will get very little flow if anything!! I'd be seeking out the fault first, co's you might go replace all the piping using all the existing fittings only to find the problem is still there you have achieved nothing!! Other than spent lots of money time for nothing!! It's better cheaper to remedy the problem first if you find the pipework needs replacing then by all means do it - Do it once do it well is my work ethic's Cheers!!
Q:Do buildings always require both types of fire extinguishers i.e. H2S (Tyep A) & CO2 (Type BC) to be available?
exactly you need a need slip joint washer depends on whether your in a mobile home or a house usually the washers are 11/8 or 11/4. That'll take care of the slipage take a look at the nut as well the threads could me stripped or it could be cracked. Don't flip the washer the tapered end needs to insert into the female/tapered end of the p-trap. as you tighten the nut it will expand and hold the joint tight as well as seal the joint. if all else fails they sell a package with a p-trap and all the washers you will need to reassemble it properly at your local hardware store. dont use teflon tape on slip joints its a temporary fix and should be used on threaded pipe fittings only, it will limit the tightening of the slip joint.
Q:Will that be all right? Then there's the PPR pipe joint on the right. Is that ok?
If you don't feel comfortable, you can ask the master to change it for a whole 2 meter tube.
Q:what is the disadvantages of the nitrile rubber?
Is this a commercial extinguisher or a small residential model. It is not recommended to refill the home ones. You should discard it a buy a new one to ensure reliability. They are quite cheap..
Q:Which running back should I go with in week 15?
If you'd ever read any of the visions of St. Catherine of Siena, you wouldn't be asking this question. The visions she had of abortionists and women who had abortions who didn't repent just BURNING are FRIGHTENING. Not to mention that Christ called it eternal hellfire. Christ used parables when He was teaching, but not when referencing Hell or the Eucharist. He was VERY literal on both counts.
Q:Can i use the ground wire to interconnect to kiddie fire alarms.. So that both announce on alarm?
In a house - can be air in the pipes or a loose hanger that allow a pipe to hit a rafter or wall board. In a car - generally a loose hanger or missing. Sometime a bolt missing on the joining pipe fittings. Your personal pipes - bad digestion, eating spicy foods, too much beer.

10 、 flared type combined bend three way pipe joint (GB/T 5634-2008)11, adjustable sleeve to end bending through the three way pipe joint (GB/T 3743-2008)12, sleeve type taper thread bending three way pipe joint (GB/T 3744-2008)13, card sleeve type three way pipe joint (GB/T 3745-2008)14, card sleeve type four way pipe joint (GB/T 3746-2008)15, clamp type welding pipe joint (GB/T 3747-2008)
Q:can you get on a airplane with a safety pin in your arm?
That isn't a safe measure to be taking. What happens when she figures out the safety pin or it comes open by itself? She could easily stick it in her mouth or just prick her fingers on it. You need to be consistent with her in telling her she cannot take her clothing off. Keep her busy with activities or with the other children. Just find ways of keeping her mind off of her clothes.
