Taco 007 Flow

DaveGateway Member Posts: 568
Taco 007 pumping to 4X Honeywell 3.5Cv zone valves.

8" past each zone valve is a pair of 3/4" closely spaced t's supplying each zones 006 pump, very little resistance back to 007.

If only 1 zone valve is open, will the pump have enough head to lift any of the others?

    add a pressure bypass valve in your loop to prevent dead heading the pump or wear on the zone valves

    I don't know exactly what dead heading is, I think it means: pump on & nowhere for the flow to go through.
    All 4 of the zone valve end sw. will go to a Taco SR501, that turns on the 007. How could it dead head?

    Good Afternoon
    Thank you, for using Taco, products. The CV will provide the pressure drop required to calculate the system resistance. Additionally, we need to know the flow rate required, to determine what the net flow rate will be, using the CV, total length of pipe, and diameter. Please advise, if you require additional assistance.
