Step 3c:
To bond the riser to the riser tank adapter, you can use
either ADH100 or methacrylate adhesive alone. However, because
ADH100 does not provide a structural joint for approximately 24
hours, we recommend the use of both adhesives. If you use both,
apply methacrylate adhesive to the outside surface of the riser
tank adapter for a quick (usually an hour or less) structural joint.
Step 3d:
Carefully slide the riser onto the adapter. Correctly ori-
ent the riser before the adhesive starts to set.
Step 3e:
Apply a bead of adhesive to the inside of the adapter
and riser joint; then use a putty knife or similar tool to form a con-
tinuous fillet between the tank adapter and the inside of the riser.
Step 3f:
After the adhesives have hardened, fill the tank with
clean water to a level 2 in. (50 mm) above the adhesive joint in
the riser, to test the watertightness of the tank and the riser joint.
Do not allow the water level to rise more than 3 in. (76 mm)
into the riser because structural damage to the tank may occur.
The inlet and outlet pipe into the tank needs to be turned up or
plugged to allow the tank to be filled.
CAUTION:
Check the tank manufacturer’s guidelines before
water testing the tank. Some tank manufacturers require a partial
or complete backfill before a tank is water tested.
Step 3g:
When the tank proves watertight, drain the excess water
to the tank manufacturer’s recommended level.
Step 4: Install Effluent Filter
Install the
effluent filter after the tank has been water tested.
Step 4a:
Test-fit the effluent filter on the septic tank’s outlet pipe
without gluing. Make sure it fits plumb. Make sure the filter will
fit as snug to the tank wall as possible while ensuring sufficient
clearance for removing the filter cartridge.
Step 4b:
Secure the filter to the outlet pipe. Two attachment
methods can be used:
• You can glue the filter onto the tank outlet pipe using appro-
priate primer and glue.
• You can use a stainless steel set screw to secure the filter.
Step 4c:
For easier access when servicing, you can extend the
cartridge handle with a longer length of ¾-in. Sch 40 PVC pipe.
Carefully slide the riser onto the adapter.
