Water Pumps & Holding Tanks

[Kurt Horvath]

Leroy

I have re-plumbed the Air Purge system with 1/4 air lines and routed
them through to the water pump bay, put a Schraeder valve on the
water filter side and closed the regulator in case the air purge
switch gets turned on accidentally. Now it can be purge it from a
clean air source. More importantly there is no chance of water
getting into the air systems.
Just about have the water pump bay finished. It is re-plumbed and the
new accumulator tank is in and charged to 25 psi. Just have to put
the pumps in and hook them up. I mounted them to a separate sheet of
3/4 plywood so they could be easily remove to be serviced. I used
reinforced vinyl tubing 210 psi to hook the pumps up to the rest of
the system using Sea-Tech also known as Watts WaterPEX quick connect
fittings. They can be used with PEX, CPVC, Copper and the dreaded
Polybutalyne, you'll need the plastic insert with the Poly. Man are
these puppies neat they just slip together and they will rotate so if
your like me and once you've glued together the pipes and you miss
calculated an angle, there is no problem. They come apart easily and
will facilitate any future repairs.
The drain pipe for the washer is on the curb side above the rear tank
and crosses over to the front tank, into the top of the tank, but
there is a second drain pipe next to it descending to the top of the
Black tank. I'll have to do some investigating. It would be easier to
put a T in the pipe and plumb from there instead of trying to go
through the top of tank..
