The Problem:
Waiting for Hot Water
It’s a common problem: turn on the faucet or shower for hot
water, then wait for it to arrive. In fact, the wait can be up to
two minutes in larger homes with multiple bathrooms and
long runs of pipe between the plumbing fixtures and the water
heater! With a Taco Domestic Hot Water Recirculation
System in place, there’s no more wait. Instant hot water!
Waiting Means Wasting
Waiting for hot water sends millions of gallons of cooled
water down the drain each year. In fact, an average family
of four wastes up to 14,000 gallons of water each year waiting
for hot water.* Water conservation is so important that
many US states and municipalities routinely impose water-
ing bans and offer rebate incentives to help conserve this
natural resource. *Source: Dept. of Energy study.
Estimated Annual Water Savings
Energy Down The Drain
Of course, all that “waiting water” contains some heat energy
(BTU’s), even if it’s only room temperature. Wasting those
Domestic Hot Water Recirculation
BTU’s and starting over with fresh, cold water to heat up
requires even more heat energy. So in addition to wasting
water, millions of BTU’s and energy dollars are wasted, too.
The Solution:
Install a Domestic Hot Water Recirculation System
The Taco Plumb n’ Plug® Recirculation System is specifically
designed for:
• Instant hot water comfort
• Water savings
• Energy savings
How a Domestic Hot Water Recirculation System Works
A standard DHW system requires a dedicated return line
from the furthest fixture back to the water heater. The re-
turn line is connected to a tee at the tank drain valve or to
the tank’s cold water supply line. A Taco Plumb n’ Plug® re-
circulation pump with an optional Integral Flow Check (IFC®)
is installed on the return line and controlled by a timer or
temperature Aquastat. The spring-loaded IFC® prevents
gravity circulation during off-cycles. The timer turns on the
pump at preset intervals, usually during peak use periods in
the early morning and late afternoon. An optional Aquastat
operates the pump to keep hot water in the line within a
set range (95°F–115°F). All supply and return lines should
be insulated for maximum energy savings.
Required Components
• Taco Plumb n’ Plug® Circulator with optional IFC®
• Isolation valves - to isolate the pump for future service
• Flow check valve - to prevent gravity flow
• Purge Valve - to remove air from system piping
• Timer control - 24-hour analog or 7-day digital timer
• Aquastat - to control temp between 95°F-115°F (opt.)
• Pipe insulation - to maximize energy savings

"On-Demand" Systems
for New or Retrofit Installations
Using the existing cold water line as the return line,
the D’MAND® System is ideal for both new and retrofit
installations. Typically installed at the furthest fixture from
the water heater, D’MAND® fits out of the way, under any
bathroom vanity. Connections are made from the hot and
cold lines to the suction and discharge side of the pump
using adapter tees and stainless flex lines provided. When
hot water is needed, the pump is activated by pressing a
starter button, runs only long enough to supply hot water
to the fixture and then automatically stops. This prevents
hot water from entering the cold line. A spring-loaded
Integral Flow-Check valve (IFC®) prevents cold water from
entering the hot line. Optional wireless RF or motion
sensor starters are also available.
