    Q:

    I have replaced several power heads on this valve, and was wondering what type of pressure this stem should require to activate the valve? With the power head removed, it takes significant down force to open the valve (IMHO)and I want to make sure this is correct. Thank you.

      A:

      The pressure required to open the valve or compress the spring to full open position is 36 psi. If the power heads are failing prematurely, we recommend opening the valve to clean out the seat assembly and checking for any other blockages at the spring.

      A:

      This taco valve needs the valve & seat assembly (SKU: 5101-002RP) as well. This will prevent the leaking into the electrical head that you have been having a problem with.
