The Basement Watchdog SP-33T and SP-50T come equipped with a built-in air
relief valve located near the bottom of the pump, next to the outlet. While the
pump is active, some water may come out of the valve. This is normal. The
valve is needed to prevent an air lock within the pump. DO NOT obstruct the
air relief valve or an air lock may prevent the pump from activating. When a
check valve is used, a 1/8” (3.2mm) air bleed hole must be drilled in the PVC
pipe above the pump. Drill the hole at a 45º angle toward the bottom of the
sump to avoid splashing water outside the sump pit. Make sure the hole is
above the water line, and below the check valve. If a hole is not drilled above
the pump, an air lock may prevent the pump from operating.
• The control unit must receive 115V AC +/- 5% and 60 Hz from the AC outlet.
• Primary pumps will not provide protection during a power outage. With the risk of
property damage from high water levels, the addition of a Basement Watchdog
battery backup sump pump system is highly recommended.
• After the initial installation, be sure to check the operation by filling the sump
with water and observing the pump operation through several full cycles.
• In instances where the discharge line is exposed to freezing temperatures, the pipe
must be sloped downward so any remaining water will drain out. Failure to do so
will prevent water from exiting the sump and damage the pump if the line freezes.
Installation Instructions
Prior to Installation
1. Visually inspect your pump. Products may be damaged during shipping. If the
product has been damaged, contact your place of purchase or Glentronics, Inc.
before installation.
2. Thoroughly read the instructions provided to learn specific details regarding
installation and use. This manual should be retained for future reference.
1. Use a pit that conforms to all local codes
and is large enough to accommodate the
pump and float switch. The minimum
requirements are 18
⬙
in diameter and 22
⬙
deep. However, larger sump pits are
preferred, since they will extend the
discharge cycle and reduce the number of
times the pump turns on.
2. Clean the pit of all debris. The pump’s
inlet must be kept clear.
3. The pump should not be set directly
onto a clay, earthen, or sand base. You
should install bricks or blocks under the
pump to provide a solid base.
4. The pump should be level.
5. Install discharge plumbing according to
local, regional and state codes. Rigid
PVC pipe is recommended.
6. An in-line check valve is recommended
to prevent back-flow. This check valve
is mandatory when sharing a discharge
line with another pump (i.e. a back-up
pump or a second primary pump).
(a) When a check valve is used, a
1/8” (3.2mm) air bleed hole must be drilled in the PVC pipe above the pump.
Drill the hole at a 45º angle toward the bottom of the sump to avoid splashing
water outside the sump pit. Make sure the hole is above the water line, and
below the check valve. If a hole is not drilled above the pump, an air lock may
prevent the pump from operating.
7. Install a gate valve or ball valve if required by any codes.
8. In instances where the discharge line is exposed to freezing temperatures, the pipe
must be positioned in a downward slope so any remaining water will drain away.
Failure to do this will prevent water from exiting the pit and damage the pump if
the line freezes.
9. If you are replacing an old sump pump:
(a) Unplug the pump from the outlet.
(b) Loosen the check valve or rubber union by unscrewing the bottom hose clamp.
(If the existing
system is installed
without a check
valve or rubber
union, saw the
pipe apart above
the sump pit.)
(c) Remove the old
pump and unscrew
the pipe and adapter.
(d) If the adapter fits into the new pump,
screw the pipe into the pump. If not,
cut a piece of rigid PVC pipe and
connect it to a 1-1/2” PVC adapter by
cementing the two pieces together.
(Follow the instructions on the PVC
cleaner and cement.) Then screw the
new piece into the pump.
(e) Lower the pump into the sump by the
handle.
(f) To avoid debris pouring onto the float,
it should be positioned on the side of
the discharge pipe opposite the drain
tile. (See diagram).
The tethered float
switch must be moving freely at all
times. Make sure the float switch
does not come into contact with other pumps, wires, pipe or any other object
that may be in the sump pit. The float switch must not come into contact
with the sump pit floor or wall. If the float switch does not move freely the
pump will not activate.
Connecting the Pump
Plug the pump directly into a properly grounded, 3-prong receptacle. For a neater
installation, secure the power cord to the discharge pipe with wire ties or hose
clamps. Keep any cords separated from each other on opposite sides of the pipe.
Completing the Installation
1. After the initial installation, be sure to check the pump operation by filling the sump
with water and observing the pump through several full cycles.
The tethered float
switch must be moving freely at all times. If the float switch does not move
freely the pump will not activate
. Be sure to check the pump is turning on and off
at the intended levels.
Note: The pump should have a “normal pumping” sound. Any
abnormal sound, vibration, or lack of output from the discharge pipe is the signal of a
problem. Stop the pump and refer to the troubleshooting guide.
2. Replace the pit cover making sure not to pinch or crimp the pump wire with the
cover. The pit cover either has a ‘hole punch’ that will allow the cord to be passed
through or one can be drilled.
Product Operation
Tether Float Switch
The tether float switch contains a single large
float. Water will lift the float switch to activate
the pump. As the pump evacuates the water from
the pit the float switch will drop and turn off the
pump. To adjust the float switch, loosen the
screw on the “P” type clamp holding the float
switch wire. Adjust the wire to the desired
length and then tighten the screw.
DO NOT
shorten the tether length to less than 4”.
After any adjustment of the float switch be
sure to check the pump operation by filling
the sump with water and observing the pump
through several full cycles. The tethered float switch must be moving freely at all
times. If the float switch does not move freely the pump will not activate.
