I have this Caleffi valve http://www.supplyhouse.com/Caleffi-280166A-1-Male-NPT-ThermoMix-Thermostatic-Mixing-Valve-140F
All the plumbing diagrams I can find show the water being "pulled" through the valve. I'm wondering if it's OK to "push" the water through the valve? Why couldn't it be done? Am I missing something in the valve's constriction that doesn't allow this?
