Q:What's the word help please?
Sure, and if it ain't broke, don't fix it. Actually, I'm kinda surprised that your original build was CPVC, as copper would be much more common. As Tony suggests, PEX is where you go, over time. Relax.
Q:Winter Tires????? XI2 or Gererals?
The best parental control is to have a non-deletable history. That would be the best way to go. One that saves to a spot on your hard drive somewhere not accessable by the user. Let the child go where they need to on the internet, and you can see what they're doing. It would be a better indication to what the child is interested in and where they go. It would be more useful than completely denying them from places. This way you don't control where the person goes at that moment, because lets face it, if you give a person a gun and say, don't kill with itthey're going to kill. If you say don't go across the street at this time, they're going across the street. Anything you produce can and will be broken. So if you just have a program of some kind that keeps a history somewhere un-detected that the user is unaware, you'll have a top selling product.
Q:HELP!!!! ME PLEASE!!!?
I think you would be better off using PVC pipe. Its very sturdy, chlorine resistant, lasts for years when burried and comes in many diameters and pressure ratings. Fittings are easily installed and you can get it anywhere. For a fountain 15mm or 20mm pipe in class 9 should be adequate but you can go up in diameter if you need too. Its really cheap stuff and when primed/glued properly will never leak. If you use any fitting with threaded joiners use plenty of teflon tape.
Q:A fire hose held near the ground shoots water at a speed of 6.7 m/s.?
The 2015 Darwin Award goes to . (insert your name)
Q:Fire alarm during heart surgery?
The Salvation Army provides blanket and sometimes first aid has them
Q:Fixing 98 honda civic lx exhaust pipe?
They're both correct. According to relativity theory, gravity is a curvature in space-time caused by mass that results in the attraction force between objects.
Q:what safety things do i need for a motorcycle?
The squeak when hitting bumps can be a couple of things. If small bumps cause a squeak replace the stabilizer bar bushings and check the links. If the car pulls left or right when hitting grooves in the road jack it up and check the ball joints. If the steering wheel shakes slowly while making a slow turn I'd inspect the tires, it would be bad belts and/or worn tread. The bottom line is you need a good alignment shop to shake down the suspension and quote you for needed repairs and then do a 4 wheel alignment. It might be a good time to think about a different vehicle before you start pumping money into that POS.
Q:how to disconnect car alarm?
better call a plumber
Q:Hydraulic pipe quick coupling principle of hydraulic pipe joint
JB/T6381 ~ 6385-1992 burking hose connector has the advantages of convenient installation, but added a tightening process. After the hose is damaged, the joint coat can not be reused, and it is made up of a steel wire braided hose. The utility model can be connected with a welding pipe joint sealed with a O ring. Pipeline system suitable for oil, water and gas as medium. Medium temperature: Oil: -30 ~ 80 degrees Celsius; air, -30 ~ 50 degrees Celsius; water, 80 degrees below JB/ZQ4427 ~ 4428-1986, three valve type hose joint assembly, do not need to remove the rubber tube of the outer layer. A slightly different diameter of hose hose, hose on the joint coat of pre compression to compensate. Hose pre compression in 31% ~ 50% range to ensure no leakage under the pressure of work, will not pull glue, cover does not break. With the welded pipe joint, quick joint, sleeve type pipe joint used for oil, water and gas pipeline system for medium, working pressure, medium temperature by connecting hose limited JB/ZQ4429 ~ 4431-1986 quick change connector (both open and closed) tube apart and self sealing pipe. In the liquid will not be lost, so it is suitable for frequent disassembly occasions. The structure is complex, and the local resistance loss is greater. Suitable for oil and gas pipeline system for medium, the working pressure is lower than 31.5MPa, the medium temperature of -20 to 80 DEG JB/ZQ4434-1986 quick change connector (both ends open) for oil and gas pipeline system for medium, the working pressure of medium temperature according to connecting hose limited JB/ZQ4435-1986
Q:Problem with a smoke detector that goes off from steam from a shower?
Mr. Nero, You don't know me yet, but I come from the future to advise you against bringing extinct species to your timeline. The problem is that your current timeline is too warm for the animals you wish to bring. Because this is my second travel to your timeline, I double warn you! You heeded the advice I gave you above but you brought the animals anyway! And grew them somewhere in Siberia. You died happy and stomped by a mammoth! Years later, your expedition was found, attracting the attention of the United States of Eurasia. When the military started to ask questions about a certain fire hydrant, the world was shaped into something you don't want to know. Everything you do, is like causing ripples in a pond, if you're time travelling, you're multiplying those ripples. Does Nature care? No. But with that kind of power you have to be responsible. (this is important part to your question).
