More than your hot water tank can put out.
Home Depot also sell's it with an elbow

Actually I had to cut off about five inches of mine to make it fit. But if you need to extend, I would ask at Home Depot if there is a tubing the same size and an inline couplet, and use PVC two part glue to affix. One could also get a piece of automotive water pump hose, (which is rated for high temp liquids, re; hot antifreeze), and use a radiator hose clamp. Just lightly rough the end of the tube with fine sand paper to give a grip surface, and make sure the clamp is well tightened.
yes, no problem,
Thank you for asking. Please contact the governing authority in New York City to determine if this is within code.
no... this is for connecting to the relief valve on the outside of the water heater.
I used a pair of channel locks.
