Universal rough-in valve

1. A universal rough-in valve comprising:

a valve chamber;

a first valve inlet configured to provide a pathway for fluid from a first supply line to the valve chamber;

a second valve inlet configured to provide a pathway for fluid from a second supply line to the valve chamber;

a first valve outlet configured to provide a pathway for fluid from the valve chamber to a first outlet line; and

a valve manifold removably positioned in the valve chamber and configured to receive a fluid mixing valve,

wherein

the valve manifold includes a first manifold inlet, a second manifold inlet, a first manifold outlet, and a second manifold outlet, and

the valve manifold includes an outlet passageway comprising the first manifold outlet and the second manifold outlet, the outlet passageway including a central portion having a smaller cross-sectional diameter than at least one of the first manifold outlet and the second manifold outlet.

2. The universal rough-in valve of claim 1 , further comprising a fluid mixing valve, wherein the fluid mixing valve comprises a pressure balance valve or a thermostatic valve.

3. The universal rough-in valve of claim 1 , wherein the valve manifold includes a venturi positioned in the outlet passageway.

4. The universal rough-in valve of claim 1 , wherein the first manifold inlet is co-axial with the first valve inlet, and the second manifold inlet is co-axial with the second valve inlet.

5. The universal rough-in valve of claim 1 , wherein the first manifold outlet is co-axial with the first valve outlet.

6. The universal rough-in valve of claim 1 , wherein the valve manifold includes a groove configured to receive a gasket, the gasket configured to form a seal with an internal wall of the valve chamber.

7. The universal rough-in valve of claim 2 , wherein the valve manifold is positioned at least partially between the fluid mixing valve and the valve chamber.

8. The universal rough-in valve of claim 1 , wherein the valve manifold includes a cavity configured to receive the fluid mixing valve, a first transition fluidly connecting the cavity and the first manifold inlet, and a second transition fluidly connecting the cavity and the second manifold inlet.

9. The universal rough-in valve of claim 8 , wherein the first transition is transverse to the first manifold inlet, and the second transition is transverse to the second manifold inlet.

10. The universal rough-in valve of claim 8 , wherein the valve manifold includes a first channel fluidly connecting the cavity and the first manifold outlet, and wherein the first transition is positioned closer to a center of the valve manifold than the first channel.

11. The universal rough-in valve of claim 1 , wherein the valve manifold includes a sidewall defining a cavity configured to receive the fluid mixing valve, a first transition fluidly connecting the cavity and the first manifold inlet, and a second transition fluidly connecting the cavity and the second manifold inlet.

12. The universal rough-in valve of claim 11 , wherein the first transition and the second transition are at least partially formed within the sidewall.

13. The universal rough-in valve of claim 11 , wherein the first transition is fluidly connected to the cavity at a first entry, the second transition is fluidly connected to the cavity at a second entry, and the first entry is positioned below the second entry.

14. The universal rough-in valve of claim 11 , wherein the first transition extends through an exterior of the sidewall such that a portion of the first transition is defined by the sidewall and the valve chamber.

15. The universal rough-in valve of claim 11 , wherein the valve manifold includes a first channel fluidly connecting the cavity and the first manifold outlet.

16. The universal rough-in valve of claim 15 , wherein the first channel is positioned closer to a center of the valve manifold than the first transition.

17. The universal rough-in valve of claim 2 , wherein the valve manifold includes a notch configured to receive a protrusion on the fluid mixing valve to couple the valve manifold to the fluid mixing valve.

18. The universal rough-in valve of claim 1 , further comprising a guide and a fastener configured to at least temporarily couple the rough-in valve within a wall opening, the fastener including a body and a head, at least one of the body and the head defining a tool engagement feature such that the fastener may be moved relative to the guide by a tool.

19. The universal rough-in valve of claim 18 , wherein the head is configured to engage a sidewall of the wall opening at an engagement point and the head includes a cam surface such that rotation of the fastener about a fastener axis changes the distance between the fastener axis and the engagement point.
