Hose bibs and most products are excluded from the requirements of being "lead free"Arrowhead has residential, retail and commercial productsValves are not intended to be used for potable (drinking) water applicationsMeasure the thin copper tube only and make sure to subtract 2" from your measurement and that is the length you need.The 2" discrepancy is because in the plumbing industry we measure from the wall back and 2" of that thin copper tube falls within the body of the valve.
Thanks for the reply.
Sorry, but I'm not really following what you're saying. The faucet drips when I have the outside spigot closed, and the water valve on the inside of the house is open. Is the spring less check valve the valve seat for the end of the stem?
Regarding the filing, when I screwed the stem into the spigot, it didn't go in all the way and it felt like it didn't fit. I got the idea from other reviews on amazon where I ordered the valve stem. Not sure if I can link to amazon, but the reviews are here - https://www.amazon.com/Arrowhead-PK8004-Replacement-4-Inch-Hydrants/dp/B000PS8OE6/ref=cm_cr_arp_d_product_sims?ie=UTF8
I basically used a dremel and ground down the back edges of the square part of the stem bit by bit until it eventually screwed in. When I compared the new stem to the old stem, the old stem had a much smaller square.
