Installers Notes

See GALLERY/Installations for pix


(Note: Below is a description of the STANDARD configuration. Some tanks may vary from this due to customer requirements. Photos are from a dual installation)

At one end of the tank, there are 2 SERVICE fittings.

One is a 40mm male connection which is both the inlet and outlet for the GREY water storage.

Adjacent to this, on the same end is a standard 1 inch male fitting which is both the inlet and outlet for the FRESH water.

At the other end of the tank are 2 female 1 inch fittings which serve as breathers. The one on the same side of the tank as the 40mm is for the GREY water, the other is for the FRESH water.



The tank should be fitted with the SERVICE fittings toward the OFF SIDE. That is, the side furthest from the kerb.

IMPORTANT: There must be a 30mm spacer fitted to the lid of the tank at the service end to provide optimum use of the tank. Fixing to the chassis should be with the use of a MINIMUM of 2 stainless steel straps, at least 50mm wide and capable of holding 150 kg per fitting point. The strap should also be fitted with a suitable rubber cushioning. Likewise, compression points to the steel chassis should be fitted with rubber strips. This also helps prevent electrolysis between the 2 dis-similar metals

Replacing existing tanks

It is common to replace an existing fresh water tank with the SAFETANK. This serves a couple of purposes.

1.    It negates the need for an extra tank.

2.    Keeps the weight where it should be.

3.    Provides a new “clean” fresh water tank

As the SAFETANK approximates the size of common 84lt plastic tanks, it is usually a simple procedure to swap over the tanks, using the existing mountings and fittings (if suitable).






It is important to note that the water connections are both entry and exit.

Grey water

The grey water is fed the 40mm fitting.

The ball valve outlet and should be before and slightly below the 40mm entry to the tank to provide a solids and sand trap for the grey water tank. This also allows for the tank to be bypassed when connected to a sullage hose.

This can be achieved by the use of a “T” piece and a slightly downward angled connection through the right angle into the tank.

Fresh water

The fresh water should be connected via the 1 inch coupling to a gravity field inlet located to the side of the van and adjacent to the tank.

The tank can also be filled via a hose coupling via a “T” connector, but this hose coupling MUST be fitted with a pressure reduction valve otherwise over pressuring of the bladder can occur causing the tank to burst.
