Greetings,
Since I'm now planning to
use two evap cores (ordered them today) in the cheeks, and both DC EWP's, I'm
trying to figure out the best way to plumb them. First, this does mean
that I'll get rid of the mechanical pump, and probably the pump housing as
well. In fact, I ordered one of the Meziere adapters for the block to make
the plumbing easier.
The adapter block has one
large threaded hole for water out to the radiators, and two smaller threaded
holes for water in. I don't really know the size of the threaded holes
yet, but I'm hoping they're 3/4" NPT for the smaller ones, and 1" NPT for the
larger. I'm planning to order two one way valves from McMaster Carr,
as soon as I verify the size of the holes.
Here's the current (never
final) plan. The large outlet from the Meziere adapter will go to a Y,
then to the top of each core. The bottom of the cores (other tank of
course) will go to the pumps. The outlet of the pumps will go back to the
one way valves, which will be screwed into the two inlet holes in the
Meziere adapter.
Here's the question of the
day. I could either run each evap core to a single pump, then to the
engine, or I could combine the outlets of the cores, and run them to both
pumps. One way, a single pump will only flow through one core,
where the other way, a single pump will flow through both. The second pump
either adds a core to the circuit, or doubles the flow to both cores.
One core, at RV cruise speed is probably all I need, and it may be all I
ever need in the winter. Does anyone have a feel for which would be
the better plumbing choice?
Thanks,
Rusty (hoping to "bring
good things to light" in the near
future)
