Why do some washers have water restriction on the outlet of the water valve (like GE Filer Flo) while others have one each of the hot and cold inlets like direct drives? I've never been able to figure out the reason despite the obvious differences.
Water Valve Outlet Restrictor

It can be helpful to have separate restrictors for hot and cold - for example where you have a high mains water pressure (cold water) but have a low pressure hot water system - gravity feed hot water tank, or an instantaneous hot water heater. In that case you can remove the flow restrictor on the hot side and leave the cold one in place.
True. Typically, the restrictors, at least in older valves, were simply various sized holes in the plastic. They could not be removed as with say a rubber washer or doughnut. They could de drilled larger though. On the other hand, the restrictor on the outlet could be removed as it was just a rubber doughnut and another rubber piece would keep it pushed down while sealing the cavity.
I'm trying to see which valve is best.
Right now my washer has a 358277 valve which for me is ideal. Nothing is restricted on the valve itself. The only limitation if the plumbing and lever valve in the wall.
