Equa-Flow

Principles

The principle of Equa-Flow

bank is the same as any other. To achieve this, the following is necessary:

1. The cold water manifold (cold header assembly) must be designed to balance the flow to each

storage tank i.e. each branch line must be the same diameter and length and be fitted with

identical ball or gate valves (refer to diagram below).

2. The heating water manifold (primary return header assembly) must be designed to balance the

flow from each water heater and/or storage tank i.e. each branch line must be the same diameter

and length and be fitted with identical ball or gate valves (refer to diagram below). Water must exit

from the opposite end to which it enters the manifold.
