COMPATIBILITY
The EcodrainTM V1000 is compatible with all water
heating technologies as well as with all types of
plumbing (copper, pex, pvc, other) and drainage
systems (ABS, PVC, Copper, Cast Iron)
DRAIN PIPE SUPPORT
If installing an EcodrainTM V1000 into a cast iron
or copper drain pipe system, install structural
supports for the drainpipe above where the ecodrain
is to be installed, and below if necessary. Cutting
an unsupported cast iron or copper drain pipe may
damage the drain system. It is recommended that
all drain pipe types be supported near the ceiling
level of the room in which the EcodrainTM is to be
installed.
INSULATION
Insulation will not have any meaningful impact on
heat transfer. Insulation may be used to limit the
impact of condensation on the surface of the cold
water pipes. If installed behind a wall, insulation
is recommended.
HEAT EXCHANGER SUPPORT
The EcodrainTM must be supported either by the
piping system or external supports. The flexible
couplings used to connect the heat exchanger to the
drain line are not adequate supports and must not
be used as such.
WATER SOFTENER
If the home has a water softener, install the unit
downstream (after) the water softener.
Parts (optional)
3/4 Cold water fittings

Wall Clearance Rerouted Drain Line
CLEARANCE REQUIREMENT
An ecodrain V1000 requires a clearance between
any adjacent structure or wall. The minimum
clearance is 3/4”, greater clearance is preferred as
this allows for easier alignment. If the clearance is
less than 3/4”, the ecodrain V1000 may not fit and
rerouting the drain pipe may be necessary. When re-
routing the drain line, it is recommended that space
is available for at least 12” of straight vertical pipe
after the pipe bends to ensure that a falling film is
properly established. This may require a smaller
heat exchanger.
At least 3” of pipe is required below the heat
exchanger to ensure adequate space to install the
mechanical coupling.
The clearance for the heat exchanger between the
top pipe and bottom pipe should be approximately
½” longer than the total heat exchanger length.

COLD WATER CONNECTIONS
The EcodrainTM manifolds have ¾” female connec-
tors designed for sweat fitting either a copper pipe
or a male PEX fitting. The lead free brass material
C83470 is 96% copper and solders like pure copper.
It is recommended to follow standard soldering
procedure. It is important to do a leak test after
soldering the sweat fittings. Do not exceed the
maximum operating pressure of 100 psi.
DRAIN WATER CONNECTIONS
The EcodrainTM must have the same nominal
diameter as the drain stack to which it is being
connected. For example, if the drain stack is 3”,
the EcodrainTM must also be a 3” model.

VERTICAL ORIENTATION
The EcodrainTM V1000 must be installed in a vertical orientation only.
Installing on a slope, even moderate, will reduce the performance
significantly. For horizontal or sloped applications, contact EcodrainTM
for products specifically designed for these applications.
Check with your local building or energy codes for the maximum
allowable deviation from vertical. Use a level in at least 3 positions
along the circumference to ensure that the unit is level.
THE HEAT EXCHANGER IS SYMMETRICAL
It is recommended to have a section of pipe of at least 12” above the
EcodrainTM to ensure that a proper falling film we be established at
the beginning of the heat exchanger at that drain water will be evenly
spread across the inner surface of the heat exchanger.

CONFIGURATION 1
Split the preheated outlet to both the water heater
inlet and the cold side of the shower fixture.
CONFIGURATION 2
Connect the preheated outlet of the EcodrainTM
to the inlet of the water heater.
PLUMBING OPTIONS
The EcodrainTM should be installed downstream
(after) a water softener or filtration equipment.
Installation must always follow the rules of the
plumbing code. When in doubt, check with your
plumbing inspector. The Ecodrain VT1000 is
certified lead free according to NSF 372. It must
only be connected on the cold water line leading
to the water heater and/or the cold side of the
shower fixtures. Configuration 1, in which water
is preheated to both the water heater and the cold
side of the shower fixture(s) is called equal flow and
provides the greatest savings. Configuration 2 and
Configuration 3 are options when Configuration 1
is not possible.
CONFIGURATIONS
When installing in a home with two showers
connected to separate drain stacks:
When two or more showers use two separate drain
stacks, then an EcodrainTM can be installed on each
drain stack (See configuration 4,5,6). On the cold
water side, the two EcodrainTM units can be
connected in parallel such that the preheated
outlet of the one unit is connected to the inlet of
the second unit and the outlet of the second unit is
connected to the water heater.
If the layout of the home makes this difficult,
one or both of the cold water outlets can be
connected to the cold side of the nearest shower
mixing valve as in configuration 2 above.
9
CONFIGURATION 3
Connect the preheated outlet of the EcodrainTM to the cold side of the shower mixing valve. Note that in
this configuration, as the water to the cold side of the shower is preheated, the overall temperature of the
shower will rise and the mixing valve will need to be set at a lower temperature. Caution must be taken to
avoid scalding.

CONFIGURATION 4
Two showers with cold water connected in series.
