Installation
(Continued)
Be careful not to strip or cross thread
plastic fittings or check valves. Flex
hose is not recommended. Rigid PVC or
metal pipe is required for a permanent
installation.
5. Place the pump with the 4 foot
section of PVC pipe on a solid, level
surface in the sump pit on an
elevated surface.
6. Attach a rubber check valve (sold
separately) to the top of the
discharge pipe. This will allow the
pump or check valve to be removed
easily for servicing.
NOTE: Check valves can be placed
directly in the pump discharge if
desired. However, for ease of
disassembly, it is recommended that
check valves be placed above the sump
as shown in Figure 1.
The remainder of the discharge pipe
installation will vary depending on
individual circumstances. Using sound
plumbing practices, route the discharge
pipe to an exterior wall by the shortest
path. Keep turns to a minimum
because they reduce flow output of the
pump. The pipe that exits the building
structure should be sloped downward
so that water will not freeze in the
pipe.
When installing the separate discharge
pipe, drill through the outside wall
with appropriate drilling equipment.
Seal the hole to prevent water from
entering.
Method 2
If a separate, dedicated discharge is not
possible as in Method 1, the BSP25
pump can be tied in to the AC-
operated pump's discharge pipe by
installing a "Y" connector. Two check
valves will be required.
1. Locate the BSP25 on a solid, level
surface in the sump pit. Do not
place the pump on a loose or sandy
surface. Small stones or sand may
damage the pump resulting in
potential pump failure.

discharge. If a 1

pipe is desired, an adapter (not
included) will be necessary. Smaller
diameter piping will reduce pump
flow, rate and performance.
3. A check valve will be required in the
discharge line of BOTH the Main AC
pump and the BSP25 pump to
prevent recirculation of water into
the sump pit. System will not
function without two check valves.
4. Cut a 4 foot section of 1-1/4 inch or
1-1/2 inch diameter rigid PVC pipe.
Cement
1-1/2 inch pipe to a threaded
fitting. Cement 1-1/4 inch pipe into
pipe coupling. Attach 1-1/4 inch
pipe section to the BSP25 discharge
adapter.
5. Screw on to pump discharge.
Be careful not to strip or cross thread
plastic fittings or check valves. Flex
hose is not recommended. Rigid PVC or
metal pipe is required for a permanent
installation.
6. Place the pump with the 4 foot
section of PVC pipe on the sump
floor or on an elevated surface if
required.

discharge pipe. This will allow the

easily for servicing.
8. Duplicate the discharge piping
arrangement for the primary AC
pump if the existing discharge line
has to be adjusted to accommodate
a second pump.
9. Glue a 45º elbow to the short pipe
on the BSP25 pump. Glue a "Y"
adapter to the short pipe on the
existing pump, as shown in
illustration for Method 2.
10. Glue a short piece of PVC pipe
between the 45º elbow and the
"Y".
NOTE: Check valves can be placed
directly in the pump discharge if
desired. However, for ease of
disassembly, it is recommended that
check valves be placed above the sump
as shown in Figure 2.
The remainder of the discharge pipe
installation will vary depending on
individual circumstances. Using sound
plumbing practices, route the discharge
pipe to an exterior wall by the shortest
distance.
