Pressure Testing
Perform a Hydrostatic pressure test by filling each line and the 6-Port valve with water.
Isolate the plumbing so that the filter, pump, and heater are not subjected to the pressure
test. Ensure cassette assembly is removed. Install the o-ring, lid and band clamp and torque
clamp to approx. 95 inch-pounds.
Pressure-test the system at a minimum of 35 psi for 24-48
hours or as local code requires. Keep the water valve secure and under pressure throughout
the construction process. When all connections are complete and it is clear that the system is
holding pressure, backfill, tamp and level all trenches.
When performing hydrostatic pressure tests or when testing for external leaks of the
completed filtration and plumbing system, ensure that the maximum pressure the system
is subjected to does not exceed the maximum working pressure of any of the components
within the system.
Preparing the System
Cut Stub-ups
1. Verify that the system is holding pressure (minimum
of 35 psi), then relieve system pressure.
2. Verify all stub-ups are above the pool shell.
3. Cut each stub-up
• For 2" collars: Cut ½" (1.3 cm) above the
cement.
• For 2-1/2" collars: Cut flush with the cement Tip: Use the UltraFlex
®
Collar
Template (part #1-17-7) (see Figure 8).
4. Use a sander/grinder to sand each stub-up smooth and level with the shell finish to
ensure proper glue adhesion with collar setting. Insert test plug in each stub-up.
5. Use a blower assembly unit (blower, check valve, air/water supply, and connectors) to
blow out debris that can gather in the plumbing during the construction process. For
technical assistance, contact Caretaker for assembly instructions. Turn on blower and
water supply and direct the flow to one zone at a time.
6. Starting at the cleaning head farthest from the valve, remove test plug and flush the pipe,
blocking and releasing pressure several times to ensure a clear line. Replace test plug
and repeat for each riser.

For Vinyl Liner Pools:
Set collar fittings before clearing lines.
1. Cut pipe stub-up flush with the pool floor. Then use an inside pipe cutter to cut it
again 1 ⅞ in. (4.8 cm) lower than the floor level.
2. Use ABS to PVC glue to secure the collar fitting. (Primer can be used on the pipe
but not the fitting. Use glue on both.) Insert collar to a full stop to ensure proper height.
3. Excavate an area (12 in. (30.5 cm) around head and 8 in. (20.3 cm) below excavated
floor) and fill with concrete to form a “thrust block” to eliminate movement of the
cleaning head.
4. Clear lines and insert test plugs limiting water use as there is no solid pool bottom.
WARNING
When pressure testing a system with water, air is often trapped in the system during the
lling process. Should the system fail, this trapped air can propel debris at a high speed
and cause injury. Every e󰀨ort to remove trapped air must be taken.Pressure testing
applies only to the plumbing and not to the pool equipment such as the lters, pumps,
and heaters. To minimize risk of severe injury or death the lters, pumps, and heaters
should not be subjected to the piping pressurization test. Refer to the manufacturer’s
instructions for the pumps, lters, and heaters for instructions regarding the maximum
pressures the pool equipment can be subjected to.
