A.Y. McDonald 5127-081 – Frequently Asked Questions
1) What does the A.Y. McDonald 5127-081 Y-branch connect, and what size are the ports?
The 5127-081 is a 708YSCC y-branch that splits one 1 inch flare inlet into two 3/4 inch flare outlets, so a single service line feeds two runs off one fitting. All three ends are flare, meaning it mates to flared copper tubing with flare nuts, not to compression or threaded pipe.
2) Is the A.Y. McDonald 708YSCC y-branch lead free for potable water service?
The 5127-081 carries the NL (no lead) designation in its A.Y. McDonald model description, which is how the manufacturer marks its lead free waterworks brass. That is the line water utilities and municipal inspectors expect on potable service work.
3) Can I use a flare y-branch like the 708YSCC on plastic or PE service tubing?
No. Flare ends seal against a flared copper tube face, so the 5127-081 is for copper service tubing only. If the service line is PE or PVC, you need a y-branch with compression (pack joint) ends sized to your tubing OD instead, not a flare fitting.
4) Do I need flare nuts or anything else to install the 5127-081 y-branch?
The 5127-081 is the branch body alone. You supply the flare nuts on each of the three connections and you flare the tube ends yourself with a flaring tool. Budget one 1 inch flare nut for the inlet and two 3/4 inch flare nuts for the branches.
5) When should I use a y-branch instead of running two separate service lines from the main?
A y-branch like the 708YSCC lets you serve two buildings or two meters off one corporation stop and one tap on the main, which means one tap fee and one excavation instead of two. Separate taps are the better route when the two services need to be independently valved at the main or the utility requires a dedicated tap per address.
6) Will a 1 x 3/4 y-branch handle two full 3/4 inch residential services?
Yes, that is the pairing it is built for. The 1 inch inlet on the 5127-081 feeds both 3/4 inch outlets, which is the common setup for a duplex or two adjacent homes served from a single 1 inch service line. If either side needs a 1 inch service, you want a larger y-branch rather than this one.
