Tempress Pressure Balancing Valve
Valve Body No. 1-594
as used with Shower Fittings
Description
This valve is precision engineered to provide satisfactory performance provided it is installed and operated in
accordance with our recommendations contained in these instructions. In order to fully enjoy the comfort,
safety and the reliability of this valve, be certain to familiarize yourself with these instructions.
Operation
The pressure balancing cartridge contained in this valve compensates for pressure fluctuations in the water
supply system through a diaphragm-connected pressure balancing mechanism. The outlet temperature will
change by no more than a mere ±2°F (1°C) with a 50% drop in either the hot or cold water pressure.
Even if the coldwater pressure fails completely, the anti-scald design will reduce the flow rate to a safe level
ensuring reliable protection against scalding. The built-in check valves prevent cross flow between the hot and
cold supplies.

Standard Installation
Back-to-Back Installation
In back-to-back installations, one cartridge
must be rotated 180 degrees to ensure
proper valve operation.
Before you begin
Make sure valve is securely fastened to studs. Be sure to remove trim items, handles, escutcheons and plates before
installation. Wrap carefully and store until finished wall is completed.
Install the valve by positioning the 1/2” shower outlet in the up position. Finished wall must be within dimensions
shown on the chart below.
On tiled wall surfaces, grouting must be either flush or raised for proper sealing of the cover plate.
IMPORTANT: It is not necessary to remove the cartridge from the valve during NORMAL soldering operations using
propane-butane gas. DO NOT USE OXYGEN-ACETYLENE. When soldering CxC connections, do not solder within
4” of valve port. Open the stop valves when soldering inlets.
To test pipe joints, pressurize both hot and cold inlets.
Installing Trim
Place cover plate on valve stem and slide into position. Install escutcheon/bonnet trim and mark the all-thread nipple,
(Item 1) were excess needs to be trimmed.
Remove escutcheon/bonnet trim and cut all-thread nipple 1/16” less than indicated mark to prevent exposure of nipple
threads. NOTE: Do not cut stem, (Item 6), or all-thread nipple until finished wall is complete and a dimension check of
handle and escutcheons/bonnet trim is done. (Stem is grooved at ½” intervals) Cut stem at least ½” past the end of
the cut all-thread nipple. Final stem length may vary based on individual handle base insertion. Reinstall escutcheon/bonnet trim and handle. Secure handle into place by tightening the handle setscrew. (Ref. Illustrations 2 & 3) Turn on water
supply to check for leaks.

Ensure that the stop ring (3) is
correctly installed as follows:
­ Rotate the cartridge stem (13)
fully clockwise.
­ Position the stop ring on the
stem such that it rests against
the stop post (14).
The stop ring must be correctly
installed prior to finish trim
installation.

Setting the Temperature Limit Stop
This valve has an upper temperature limit stop , which can allow desired and
safe hot water temperature (recommended maximum is 110°F). This stop
may be adjusted once the valve is installed. Before making this adjustment,
run the water with the valve turned to the hot setting. If the water temperature is too high in this position, then perform the following adjustments:
· Remove the trim (handle, escutcheon and cover).
· Remove the all-thread nipple, retaining screws and retaining plate.
· Remove the broach and the limit stop. Do not remove the mechanical
stop.
If for any reason the mechanical stop or the cartridge is removed, the following steps must be performed:
1.Close the valve by turning the cartridge stem clockwise
until it stops, (Do not forcefully rotate).
2. Position the mechanical stop on the cartridge against
the stop block as shown in Illustration 5 and continue with the following
steps.
· From the CLOSED position, rotate the cartridge stem counter-clockwise
until the desired temperature is achieved.
· Place the limit stop on the cartridge stem against the stop block as shown
in Illustration 7. Rotate several times to make sure the stop is at the desired
temperature setting.
· Replace the full extension broach, retaining plate and screws, all-thread, nipple and locking nut. (NOTE: For stem to be fully seated into cartridge, allthread nipple and locking nut must be tightly secured against retaining
plate.)

O­ring seal on the inlet of the cartridge is
faulty or seat assembly is damaged.
Check the O­ring & seat for cuts or over­
heating damage during installation.
Replace if necessary.
Water insufficiently hot.
Adjustable handle position stop incorrectly Refer to the instruction on “Setting

Remove the cartridge (See Page 3). If
debris is lodged in the inlet of the cartridge
or check the valve located in the cast valve
body. The debris can be removed with a
straightened paper clip or fine wire. Gently
insert the wire and move it in a circular
motion to dislodge any debris.
