I have two 1.5" PVC lines I need to connect with a Wye connector. To
ease any future servicing of the check valves in the system (for my
sump pump & battery backup pump) I would like to have a union just
upstream of the wye connector (rather than a hard joint).
To reduce the number of joints I have I would like to connect a
standard union to a street wye OR a street union ( if it exists) to a
My problem is, I can't find any place that has street unions online.
Do they even exist?
Also, is there any issue with connecting a standard union directly to
a street wye (or vice-versa)? Does there need to be a length of
straight pipe between the union and the wye?
Or should I just use a street wye with a rubber coupler?
