A.Y. McDonald 74758-22-1-1/2 – Frequently Asked Questions

1) Is the A.Y. McDonald 74758-22-1-1/2 the same part as AYM 5141-170?
Same part, two numbers. A.Y. McDonald catalogs this 1-1/2 inch waterworks valve as 74758-22-1-1/2 and cross-references it as 5141-170, so ordering by either number gets you the identical component. If your engineering drawing or existing plumbing spec lists 5141-170, that is what this is.
2) Is this A.Y. McDonald valve meant for a finished, visible installation or underground?
Rough-in only. The 74758-22-1-1/2 is built to go behind the wall, underground, or at the service connection point, not as a finish-grade fixture someone sees. If you need a chrome or decorative stop at a fixture, look at a finish supply stop instead.
3) Does A.Y. McDonald 74758-22-1-1/2 come in more than one size or configuration?
One configuration is offered under this model: 74758-22-1-1/2, the 1-1/2 inch version. The size is baked into the model number, so other trade sizes carry their own A.Y. McDonald part numbers.
