INSTRUCTIONS FOR CLEANING THE DRINKING WATER FILLER PIPE IN MOTORHOMES
By zappysblog.co.uk
The filler pipe can be cleaned in two ways:
Method 1
Using a 12v pump to dose the liquid through the jetting device to clean the inside of the filler pipe. I use the
EASY 14 14l per min (£11 from EBay) to transfer fresh water from my Fiamma Roll Tank but any water carrier will
suffice.
Method 2
If you don’t have a 12v pump (see page 4) the disinfection can be achieved with the use of a watering can to
dispense the tablet solution into the filler pipe whilst using the Zappyjet at mains pressure.
Method 1: Cleaning the Filler Pipe with the Use of a 12v Electric Pump.
1. First you will need to purchase a
length of 1/2 inch clear plastic tube
(although any standard 1/2 inch hose
will fit) of a length equal to the
length of the filler pipe usually 1M is
about right. Connect the tube to the
device and fix with a jubilee screw
clip. (It will be easier if you warm the
end of the hose in hot water)
2. Start with steps 1 and 2 of the Tablet
instructions (making sure the hot system
is full) and add the correct amount of
tablets for the size of your tank (from the
table with the tablet instructions) to the
container and fill with water. The
solution will be stronger but that’s OK as
it will be diluted to the correct strength
later and it will help to eliminate the bio
film on the inside of the filler pipe.

3. Join the pipe from the pump to the
Zappyjet and fasten with a Jubilee clip. I
use 3/8” clear plastic hose which slips
inside the 1/2” clear plastic hose available
from aquatic or caravan centres.

4. Insert the 12v electric pump into
the container.
5. Insert Zappyjet into filler pipe.
Make sure that this is done
before switching on pump or
chorine solution will be sprayed
from the jets. Observe the safety
guidelines with the tablets, and
wear eye protection as a
precaution.
6. Switch on the pump
and work the jet slowly up
and down in the filler pipe
until all the liquid in the
container is gone.
Insert Zappyjet before
switching pump on.

Here you can see how even at 45 deg. to the
vertical in a 11/2 inch diameter tube, the
Zappyjet keeps a head of liquid behind the
jets allowing the solution to clean and
disinfect the pipe

7. When all the disinfection solution has
been used disconnect the pump and
connect the Zappyjet to the to the mains
water supply hose via a standard 1/2 inch
hosepipe. For this I use a standard 3/4
inch hose coupler, but any of the Hozelok
fittings range will fit. Alternatively
connect the Zappyjet directly to the hose
pipe using hose clip provided.
8. Insert the Zappyjet into the filler pipe
and turn on the mains water. Work the
jets up and down the filler pipe to wash
away the slime, algae etc.

water on, slowly

9. Continue until the filler pipe is clean or
until the tank is full and continue from
step 3 to 7 of the cleaning instructions
for the tablets.

Method 2: Cleaning the Filler Pipe without the Use of a 12v Electric Pump.
Many people use a watering can to keep the fresh water topped up when on site. You can use the watering can
to dispense the tablet solution whilst cleaning the filler pipe with the Zappyjet connected to a mains water hose
pipe.
1 Start with steps 1 and 2 of the Tablet
instructions making sure the system is
full and add the correct amount of
tablets for the size of your tank (from the
table with the tablet instructions) to the
container and fill with water. The
solution will be stronger but that’s OK as
it will be diluted to the correct strength
later and it will help to eliminate the bio
film on the inside of the filler pipe.
2. Connect the Zappyjet to the to the
mains water supply hose via a standard
1
/2 inch hosepipe. For this I use a
standard 3/4 inch hose coupler, but any
of the Hozelok fittings range will fit.
Alternatively connect the Zappyjet
directly to the hose pipe using hose clip
provided.
3. Get someone to slowly dispense the
tablet solution into the filler pipe. Turn
on the mains water whilst pouring in the
solution and working the Zappyjet up
and down the pipe. Keep adding the
solution until it has all gone.
(Adhere to safety instructions as above)

until the tank is full then continue from
