RECOMMENDED TOOLS: Screwdriver, level, 12" adjustable wrench, 10" pipe wrench,
5/16", 3/4", 9/16", 1/2" and 7/16" open end wrenches.
LOCATION OF UNIT: Installed indoors only on the inside wall, and where the temperature
does not go below 50°F. Used with single bubbler wall mounted fountains only. The waste
and supply heights should be taken from the installation instruction sheet of the fountain.
SUPPLY LINE: The minimum recommended line size is 1/2" IPS with 30-90 psi (2-6 ATM).
Where sediment or mineral content in water is a problem, an inlet filter is recommended.
PLUMBING CONNECTIONS: Inlet valve is 1/2 IPS (F). Waste trap outlet is female 1-1/4"
IPS.
INSTALLATION PROCEDURE
GENERAL NOTES:
1. For all plastic push-in type fitting connections, only connect NSF-61 copper or
plastic tubing. Stainless steel or glass tubing is not recommended. The
following assembly instructions must be followed to ensure a watertight
connection:
a. Cut tubing square and clean.
b. Mark from end of tube the length of insertion (See table below).
c. Push tube into the fitting until it bottoms out.
d. To remove, depress collet and pull tubing out.

1/4” ±.005” 11/16”
3/8” ±.005” 3/4”
1/2” ±.005” 7/8”
Refer to Installation Drawing for installation. Use pipe joint sealant on all water connections.
STEP 1: Locate and mount the fountain on wall in desired location per Installation Drawing
shipped with fountain. Attach waste bend to underside of fountain and mark center
of tube on wall, drill 2-1/2" hole through wall at mark. Then locate and drill 1/2"
diameter hole and 1- 3/8" diameter hole through the wall (as shown on Installation
Drawing).
STEP 2: Mount freeze-proof cabinet on backside of wall so that waste, supply and operating
holes in cabinet line up with holes drilled through wall. Then cut and thread 1-1/4"
nipple long enough to allow the waste bend to enter the nipple and the 1-1/4" slipjoint nut and washer to be tightened fully on the fountain side. The nipple must be
long enough to be threaded into the 1-1/4" IPS elbow in cabinet (see view A on
Installation Drawing).

INSTALLATION PROCEDURE
STEP 3: Snap in 1/8" bushing (provided) before feeding the 1/8" tubing through the 1/8" IPS
pipe sleeve (not provided) (see view C on Installation Drawing) then attach to the
push button and secure with the compression nut hand tight only. Bend the 3/8"
copper tubing (provided) into appropriate hole and insert through the 1" IPS pipe
sleeve (not provided) from the cabinet side (see view B on Installation Drawing).
Connect tubing to drain valve fitting in cabinet and measure, cut and connect tubing
to bubbler. Be sure the tubing has a uniform slope downward from the bubbler to the
fitting on top of the drain valve. Avoid low spots, which might collect water causing
ice plugs in freezing weather.
STEP 4: Flush the incoming water supply line before hook-up and install a shut-off valve (not

TROUBLESHOOTING
PROBLEM
REPAIR CHECKLIST
1. Bubbler Flow Control. 1. Adjust pressure regulator:
a. Loosen the locknut.
b. Rotate the knob clockwise to increase flow or
counterclockwise to reduce flow.
c. Tighten the locknut.
d. Repeat the above steps until the bubbler flow is correct.
e. Replace pressure regulator if necessary.
2. Insufficient bubbler flow 2. a. Check that the shut-off valve (not supplied) is wide open.
b. Verify minimum 30 psi supply pressure.
c. Clean inlet strainer screen located in the valve body.
d. Adjust Pressure Regulator (Refer to Step 1).
3. No flow 3. a. Check for leaks in the air tubing going from the push button
to the valve.
b. Make sure the air tubing compression nuts are hand tight.
c. Disconnect air tube from push button assembly. Blow into
tube to verify valve function. Replace valve if necessary
(Model 5881).
d. Disconnect air tube from push button. Place finger over air
outlet. Push button to test diaphragm. Tighten diaphragm
cap screws. Replace diaphragm assembly if necessary
(Model VRK2AV).
4. Continued insufficient or varied

height of bubbler flow.
b. Replace pressure regulator if necessary.
5. Continuous bubbler flow. 5. a. Insure that push button is not obstructed and springs back to
normal position.
b. Remove four screws which secure plastic diaphragm block
to brass valve body. Pull plastic and rubber diaphragm
assembly out of valve body. Locate tiny hole in rubber
diaphragm just under lip of plastic part. Clean debris from
this hole. Inspect valve seat for grooves. If seat is worn,
replace with stainless steel seat (newer models) or replace
valve (older models, integral brass seat).
c. If valve seat was OK and diaphragm holes were free from
debris, inspect rubber button located at center of floating
steel disc in valve diaphragm block assembly. If button is
worn, turn disc over or replace disk (Model VRK2AV).
d. If diaphragm and seats are in good condition, stretch spring
slightly. Spring is located behind floating stainless steel
plate.
e. Insure that air bleed port on valve plastic block assembly is
not plugged.
6. Water leaking from valve box in

wall.
b. The drain-back freeze protection feature drains through a 1”
air gap surrounded by plastic funnel (splash-guard). If drain
is plugged, water will spill out of funnel. Unplug drain.
7. Fountain line from valve box to
bubbler blocked with ice.
7. a. Check slope of tubing to bubbler, must slope downward from
bubbler to drain valve.
b. Clean or replace drain-back valve threaded into tee strapped
to plastic funnel (Model 6518FRDV).
General Notes: Before tightening nut and ferrule assembly, push tubing into fitting until it bottoms out to
ensure correct engagement with O-Ring.
