Label says to finger tighten, no tools needed
I used a pair of channel locks.
Home Depot also sell's it with an elbow
It met the 2012 Uniform Plumbing Code, but the 2015 Uniform Plumbing code requires the discharge pipe be rated for the temperature requirements of the system. A water heater relief valve is rated at 212 degrees and polypropylene is rated for a maximum temperature of 180 degrees.
Is the actual tube 3/4 inch too? I need to buy an elbow and need to know what size to get. Thank you.
no... this is for connecting to the relief valve on the outside of the water heater.
The tube is 63" in length, not 0.63" in diameter
I couldn't find any, I jerry rigged it by using a dremel tool and removing the threads from a 1/2 inch female threaded elbow til it fit and then was able to use standard 1/2 inch plastic pipe from there.
More than your hot water tank can put out.
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.
