Question:

Pipe Static Pressure question?

So I have two pipes, each 50' each, 6 in diameter, with 6 elbows. What is the static pressure (resistance) in inches of the pipe?Thanks

Answer:

Check for any imperfections on the part you are connecting to like old sealant or pin points on the metal
Did you put the ferrels on the pipe 1st. If your talking pressure fittings, what I do is after putting the ferrels on the pipes and putting the pipe into connector is wrap one turn of teflon around the ferrel and threads.
You are sitting behind the rear wheel, where the vehicle is most stable. By going over the speed bumps, the suspension tries to keep the tires on the ground and makes the bus bounce.
That's taking the tin foil hat to a whole new level.
I'd do better if I knew what kind of pipe and what kind of connections, but I'll assume the pipe is metal. For copper, compression fittings are sometimes used by DIY's instead of soldering, but can leak fairly often on initial use. For steel, if used for the complete install, sometimes a few in-store cut lengths have to be made, then threaded, and then it's the skill of the machine operator, who may have overcut threads. Finally, reuse of older fittings can be problematic, as can old male threads on steel pipe. For either type, your use of pipe thread compound /or TFE tape was completely appropriate. Might be some question as to whether your tight fittings are tight enough. With either type of pipe, it is actually surprising how much sheer force is required. At this point, I'd really crank them down very strongly and see if that stops the leak(s). If you find that you can get another half-turn with the wrench, it wasn't tight enough. If using compression fittings, if you take one apart and find that the ring on the copper still slides off, it wasn't tight enough. I'd also tend to replace any old fittings, and then any new ones that continue to leak.
