IMPORTANT: Please read all instructions before commencing installation.
1. Excavate hole for tank. Excavation should be 100mm deeper than tank.
Approximate excavation hole size to allow:-
FASTFLO MINI 950mm deep x 1.0m diameter
FASTFLO 1000 1.8m deep x 1.5m diameter
FASTFLO 1500 2.2m deep x 1.5m diameter
FASTFLO 2000 2.7m deep x 1.5m diameter
2. Lay 100mm of sand, pea or drainage metal in base of excavation, in order for tank to be bedded on a flat base,
and also shaped to suit tappered base of tank.
3. Lower pump station into excavated hole and check for level. Pump station lid should be flush with finished
ground level.
4. Tank should be backfilled as soon as possible, as follows:
For low water table areas:-
Partially backfill with a cohesive backfill and compact in 300mm layers around tank (up to sewer inlet level
only) using a mechanical plate compactor or vibrator. Ensure that tank is filled with water and kept same
level while backfilling tank.
For high water table areas:-
If bottom of tank is below maximum ground water level, then tank should be bedded down in concrete
whilst still fresh, and concrete continued up side of tank to just above second rib, or more for high water
table areas. Ensure that the tank is filled with water ahead of pouring concrete balanced and kept at the
same level while backfilling tank.
If the tank is in a trafficable area, then an additional concrete cover slab should be poured with heavy duty
lid option. (See Note 16)
Alternatively, continue concrete up sides of tank to the underside of the cover slab (inlet and electrical
outlet pipes to be done first – Refer No’s 5 – 11).
5. Cut sewer inlet hole with hole saw, in the desired position (usually between 1st and 2nd rib from top) and
insert large rubber inlet uniseal in hole from outside.
Hole sizes are as follows:- (Refer to seperate instruction page)
For 110mm uPVC = 127mm hole saw size
For 160mm uPVC = 170mm hole saw size
Lubricate inlet uniseal with o’ring lubricant or similar, and insert PVC inlet pipe (gravity drain) into tank.
