Congratulations on purchasing a
Nova-Flo flood prevention device.
®
Fitted correctly, Nova-Flo will provide peace of mind to homeowners,
®
landlords, hotels and care providers by protecting against overflowing
baths that would otherwise result in costly flood damage and lost rental
income. Since activation substantially shuts off tap supplies Nova-Flo
will also prevent water wastage and reduce energy consumption.
In some instances, Nova-Flo can be installed to kitchen sinks and basins.

Recommendation
Installing Nova-Flo to a bath or sink requires an understanding of the
®
individual plumbing arrangements. Installers must ensure water supplies
can be isolated.
We recommend using a qualified professional who is familiar with work
of this nature. Nova-Flo must not be installed under any tension
®
and is designed to be used with hand tightened connections.

Do not use soldered or compression fittings or solder flux in direct
contact with the unit. Care must be taken to avoid any heat transfer
to the unit if soldering fittings in close proximity.
Positioning
The unit must be located between the overflow outlet (See Fig. 3) and
the waste trap, as close to the overflow outlet as possible. If required,
fixings such as cable ties or flexible wire can be used through the ears
(Fig.1, D) to support the unit in the preferred position. This will allow any
excess water flowing from the overflow outlet of the bath to pass through
the unit causing activation of the valves to shut off the supply water.
The positioning of the unit is the same for all types of installations.
The location of taps will have no effect on how the Nova-Flo
making it suitable for virtually any tap style or location.
Connection to overflow pipe
Nova-Flo will fit the majority of flexible overflow pipes found on common
®
bath overflows. The existing overflow pipe will need to be cut to leave two
lengths. Take care measuring to ensure that there is an adequate length
of pipe leading to and from the barb connectors.
The barb connector (Fig.1,A) is attached
to the Nova-Flo body by insertion and
®
rotation of 45 degrees clockwise (Fig.2).
The four points on the barb connector must
line up with the point indicators on the body
and cap when fully secure.
The barb is set at an angle to aid off-centre
installations. There are four positions which
it can be set to.
There are two sizes of overflow barb
connectors supplied with Nova-Flo
to fit the majority of flexible overflow pipes available. The overflow pipe
should be pushed onto the barb connector firmly, creating a watertight fit.
For a tight fitting pipe, submerge the overflow pipe in boiling water
to soften it enough to push over the barb connector. Take care not to
scald yourself.
For a loose fitting pipe, use the supplied rubber sleeve to enlarge the
barb connector. A small smear of silicone sealant on the outside of the
sleeve will aid insertion into the pipe.
Please ensure all fittings are watertight by looking for leaks during
testing once the installation is complete.
