waterbutt gauge kit is really easy to fit. Please read the following
before starting. Each gauge contains the following:
1 x Tank Fitting, O-Ring & Nut, 1 Metre PVC
Tube, 1 x Tube Clip & Screw, 2 x White Floating Beads.
Step 1. Empty your waterbutt. Work out
the maximum height that the water will sit in the tank i.e. the
level of your overflow. The pvc tube is one metre long and will
need to be attached so that it is at least 5cm above the top of
this level. The tube can be cut to length later on if necessary.
Step 2. You will need to work out where
you want to position the tank fitting. There are various options.
Some people prefer to put the gauge to the side of the tap and some
people just above it. The fitting does however need to be at least
6cm above the bottom of the tank to avoid silt blocking it up. Important:
The fitting must be located in an area of the plastic that is as
flat as possible i.e. not textured, on an uneven curve or on a seam.
If your waterbutt is textured, you will need to find an area that
is very smooth otherwise the o-ring will not be able to seal correctly
and a small amount of water may drip out. Silicone sealant can however
used if this occurs. Later you will need to reach inside the tank
with long nosed pliers to attach the white nut, so make sure you
can reach the final position.
Step 3. When you have worked out where
the fitting will go, you will need to carefully drill a hole through
the plastic. If possible, drill a test hole through the top of the
waterbutt where it wraps back into the centre, hidden just under
the lid to see how the plastic behaves when it is drilled. Important:
The fitting is designed for a 10mm hole only. When you
are confident you can drill a clean hole, move onto drilling the
main hole. First make a small mark in the plastic where you want
to drill with a bradawl for example. Make sure the bradawl doesn't
slip. Lay the waterbutt on its side so it is horizontal and drill
the hole in two stages, first with a sharp 5mm or 6mm drill and
then with a sharp 10mm. Drill carefully (don't let the drill slip)
and you don't want any plastic burrs or to tear the plastic. By
drilling in two stages, these burrs are minimized. If any burs are
created, carefully remove them. The outside surface must be clean
and smooth. If you can, remove any burrs from the inside of the
tank, so the nut fits evenly.
Step 4. Push the fitting through the tank.
The o-ring goes between the fitting face and the outside of the
tank as supplied. The black fitting nut fits a 14mm ring spanner
and the white fitting fits a 17mm ring spanner exactly. However,
one of the best ways to attach the nut is with long nosed pliers.
The nut has been pre-fitted on the adaptor the correct way round
i.e. with the four round dots innermost. With the tank vertical,
you will need an assistant to hold the fitting and turn it clockwise
whilst you lean into the tank and hold the nut in position accurately
with the pliers, in a similar way to that which most waterbutt taps
are attached with a nut. Make sure the nut is aligned correctly,
be careful not to cross thread the plastic nut, although the fitting
is designed to help avoid this happening. Release the grip on the
nut whilst your assistant turns the fitting to check the nut is
rotating evenly once the nut has taken a few turns (a torch may
help see the nut). When you are happy the nut is aligned correctly,
gently tighten the nut. Important:
There is no need to tighten the fitting more than finger tight.
Indeed, if it is tightened more than finger tight, damage to the
fitting will occur. Also, over tightening can cause the O-ring to
push out of the central position. If this occurs slacken the nut
and re-tighten, reducing the amount of force on the nut. The final
position of the barb needs to be vertical. You may need to slacken
the nut slightly to achieve a vertical position. The nut does not
need to be very tight at all.
Step 5. Now the fitting is attached, carefully
push on the pvc tube. You can wet the end of the tube to help it
slide on if necessary. Hold it vertically and work out where the
tube clip will be located. This ideally needs to be above the maximum
waterline as a screw holds it in position. The clip can be located
on the lid or just under it. If the clip needs to be located below
the maximum waterline, and it does leak slightly, you could put
some sealant around the screw. Drill a very small hole or use a
fine bradawl to allow the screw to tighten the clip to the tank.
Push the tube into the clip. The tube length can be shortened if
required by cutting it with sharp scissors for example.
Step 6. Finally, drop the white floating
bead into the tube. As the water rises and falls, the bead will
follow the water level, clearly marking the position of the water
inside the tank. A spare bead is supplied should it be required.
No problems have been reported with the installation
of the fitting. If however the fitting should ever show signs of
very slight leaking, you may need to put some sealant around the
thread and o-ring. The easiest way to remove the fitting is to place
the ring spanner or socket over the nut and ask an assistant to
undo the fitting in an anti-clockwise direction. The gauge has been
tested in freezing conditions without issue, however it is recommended
that waterbutts are emptied before a heavy frost or during periods
of severe weather to avoid expansion damage. Service parts are available
