Mercyhealth Hospital and Medical Center – Crystal Lake


The $105 million facility will be home to a hospital with private inpatient and intensive care suites, surgery suites,
emergency care and diagnostic services, as well primary and specialty care physician offices.

KEMPER FLOW SPLITTERS BEING INSTALLED

The new Mercyhealth facility currently under construction will have 70 of the Kemper Flow Splitters installed in the potable
hot water distribution piping to help in recirculation, flow and distribution close to the outlets within the rooms. Installed
sizes will range from ½” to 2”.

Benefits of the Flow-Splitter in a hot water installation:
• less hot water return pipework
• reduces energy consumption
• reduces installation and operating costs
• increases user comfort
• maintains targeted hot water temperatures throughout the installation
• Lead and dezincification-free brass alloy material in compliance with the Uniform Plumbing Code (UPC) and National
Plumbing Code of Canada
The Kemper Flow Splitter is a lifetime building product that does not require maintance or servicing. It is like any other
circuit setter or check valve that is installed in the building.


People need to understand that the Kemper Flow-Splitter is a non-serviceable valve and does not need to be
maintained. As simple as that. They can believe what they want but our experience and scientific data prove
otherwise.

The service life through 15 years of installations (well over ½ million valves currently in use) and relentless cycle
testing has been estimated to be 50 years (see previously attached quality document).
It is often confused with but is not a check valve, and the quality document provided alludes to this and to the
fact that the Flow-Splitter insert cartridge does not include the same stress points of a check valve where
sealing against flow direction is critical. Although the cartridge is manufactured from similar materials, it does not
experience the continuous stress forces that a check valve does. This makes the cartridge even more robust
within its specific application and function. As a result, there are no identified critical stresses, no reported
deterioration and no loss of function resulting from normal use. For this reason, we have determined that the
Flow-Splitter will not require maintenance, service, or replacement.



STATE OF ILLINOIS PLUMBING CODE
The Kemper Flow Splitter is approved for use in the State of Illinois.
Below we have the approval letter from Brian Cox.


KEMPER FLOW SPLITTER IDPH APPROVAL LETTTER
In addition, we have approvals from Illinois Code bodies to support the installation of Flow Spitters without unions as
it considered the same as a circuit setter, etc…

APRIL 2022 1

CODE EXPLANATION BELOW

Illinois Code Section 890.350



Unions may be used in the drainage and venting system when accessibly located above ground. Unions
shall be installed in a water supply system within 5 feet of regulating equipment, water heaters, water
conditioning tanks, water conditioning equipment, pumps, and similar equipment which may require service
by removal or replacement. Where small equipment may be unscrewed, only one union shall be required.
I would not consider this a regulating piece of equipment, no different than a circuit setter. Hence, unions are
not required.

I. DESCRIPTION AND OPERATION


The Reduced Pressure Principle (RP) device consists of two independently-ac�ng, spring-loaded check
valves, together with a hydraulically dependent, mechanically independent pressure differen�al relief
valve, located in the zone between the check valves. Two resilient seated shut-off valves and four test
cocks complete the assembly. The first check is designed to maintain a minimum of 5 psi across the
check valve. The second check is designed to maintain a minimum of 1 psi across the check valve during
normal opera�on. The relief valve operates on a differen�al pressure. Supply pressure on the upstream
side of the first check valve acts against the diaphragm to close the relief valve during normal opera�on.
In the event of back-pressure, the relief valve will open to maintain the pressure in the “zone” at least 2
psi less than the inlet pressure. The flowing and no flow condi�ons are illustrated in Figures 1 and 2. A
minimum supply pressure of 20 psig is normally required to fully shut the relief valve and open both
checks.

II. INSTALLATION

A. The RP must be installed in an accessible loca�on to facilitate periodic field tes�ng and maintenance.

B. The loca�on selected should have adequate drainage for relief valve discharge. The device should
never be placed where it may be submerged in standing water.

C. Flush all upstream piping thoroughly to remove foreign ma�er prior to installing the device.
D. The device must be installed in the horizontal posi�on. A clearance between the lower most por�on
of the device and flood grade or floor should be provided for ease of maintenance.


APRIL 2022 4

E. When shut-off valves are provided separately, they should be installed with a test cock on the
upstream side of the inlet shut-off valve.
F. A�er installing the assembly and with downstream or #2 shut-off valve closed, pressurize the device
and bleed ALL air through test cock #4. Then open #2 shut-off valve.
