I just ordered in the new Taco 007 ECM pump (mostly for the cool LED), but in reviewing the installation instructions, I came across this:
CAUTION: Installations at elevations over 5000 feet must have higher fill pressure of 20 psi minimum to prevent pump cavitation and flashing. Premature failure may result. Adjust expansion tank pressure to equal fill pressure. A larger size expansion tank may be required.
We're at 7,100'. I've been using a regular 007 for years with no apparent problems. Boiler pressure has always been set about 12 psi.
Am I understanding this correctly? Do I need to boost the pressure to 20 psi?
Tnx.
