Whale Point Installation

Nice project this one if you’ve had enough of lugging water bottles in and out of your Eriba. In this example Richard installed a Whalemaster water socket into a 1997/1998 Triton 430 GT. This model has a washroom, and so he had two bottles to keep full of water.

Tools required

  • Screwdriver (Phillips type)

  • Hacksaw blade (fine tooth)

  • Electric drill

  • 5mm drill bit

  • 18mm drill bit

  • 12mm drill bit

  • Measuring Tape

  • Pliers for stripping and cutting wire

  • Multimeter

  • Strong Magnet

  • Masking tape and pen

  • Coarse file

 

Parts required

  • 1 Whalemaster socket

  • 1 Whale Pump (model 881)

  • 3 metres of 32/02 cable in blue

  • 10 metres or so of 8mm ID (internal diameter) tubing

  • Y-connector for tubing

  • Cable ties

  • 2 x 3/16 spade connectors

  • In line cable connector (butt type)

  • Terminal block (often called ‘chocolate block’)

  • Butyl mastic sealant

Step 1

This is the most critical part of the install, as getting it wrong will mean you have hole in the side of your Eriba that is in the wrong place! So remember, check, double check and check again that you have the right location.

As I have mentioned I have a washroom in my Triton and so because I have taps both sides of the caravan it makes no difference which side I mounted it. Obviously I chose the side opposite to the door as this keeps the bottle out of my awning.

I used the window as my datum edges, as they are the only edges that I can see from inside and out. I firstly worked out how far horizontally from the window I wanted it to be on the inside. I have a small cupboard under my washroom sink, in this cupboard is a removable base that reveals a very small space that the back of the socket could be. I carefully calculated where I needed it to be then worked out how far across from one of the window edges that would be, then transferred these dimensions to the outside where I marked it up.

NOTE - For marking up, it’s a good idea to cover the rough location of where the socket will be with masking tape, you can then use a biro to mark your measurements, and the tape can then easily be removed once the hole is cut.

For the height, I checked and double checked that I could have this socket at the same height as the other two. I must have got lucky because it seemed fine.

OK, so you’ve marked it up and you’re ready to drill……..hang on a second, BEFORE you do, make one final check.

**WARNING - MAKE SURE YOU AREN’T GOING TO HAVE TO CUT THROUGH THE STEEL FRAME**

Take the magnet and check where you will be cutting out the main hole, if the magnet sticks to the side of the caravan right in the middle of your proposed hole, change your plans and relocate the hole.

I got really lucky, I had a section of steel frame running down right at the edge of the hole which meant I was able to secure the socket into the frame. Of course it would have been fine had there not have been any steel, but having it gives much more support to the constant plugging and unplugging that this socket will have to endure.

Ready to cut the hole out? OK, my template that came with the socket tells you which size hole to drill where, but I have one piece of advice, drill an extra hole……..why? Get your 5mm drill and drill right in the middle of where the large cutout is going to be. Once you are through, check inside the caravan and see how good you measuring is. The good thing about doing it this way is that if you are 10-20mm out, you can still move across and the hole you just drilled will still be removed by the large cutout, so no-one will ever know!

Once all four corners are drilled at 18mm, use the hacksaw blade to complete the large cutout.

NOTE – I removed the blade from its handle and used more masking tape on the end so that I could hold it safely.

Now clean the large hole up with a coarse file until the socket fits nice and snuggly.

 

Step 2

Drilling the mounting holes is a cinch now that the socket fits into its hole. Just push the socket into it’s hole (you can remove the flap on the socket, and drill about 10mm deep using the 5mm drill in each corner (see note below). Once you have done this, remove the socket from the side and complete the holes to suit the screw length.

NOTE – If you did get lucky and also have a section of steel frame that you can screw into, instead of the 5mm drill, use a suitable self tapping drill and screws of your own. Self tappers will hold very securely into the steel frame

Once all four corners are drilled, insert the supplied flat nuts that came with your socket behind each hole. The insulation will keep these in place and they are there to give the screw something to screw into.

Using the screws provided (or self-tappers where necessary) fit the socket, use a sealant as described by the socket instructions to prevent water ingress.

That’s it! Worst bit over, you now have a Whalemaster water socket - that does nothing!

Step 3

Let me deal next with the wiring. At this stage, I am not going to explain exactly which wires I moved to where, but just give a diagram to explain what needs doing.

 

 

 

This is how to change the wiring to suit your new socket and pump. The upper diagram on the left shows how the existing circuit works.

If you only have one tap in your Eriba then you will probably have a circuit more like this one.

 

 

 

The lower diagram is how I have re-wired it. Each switch can turn the pump on. Obviously the pump will only generate a fixed flow of water, so having both taps turned on will halve the water flow to each tap. However, for the ammount the taps are used this does not cause any noticable problems.

 

These changes can be achieved by adding only one wire from the electrical box to the new socket, so there is no need to lay new wires to the taps, just use the existing wires. If you need more detail, let me know and I’ll do my best to explain.

 

Step 4

Now the wiring is done, and the socket fitted, you are ready to run some tubes from the back of the new socket to each of the taps.

I chose to drill almost directly below the new socket using a 12mm drill bit. This allowed me to run a pipe out through the bottom of the caravan. I then drilled a similar hole on the other side of the caravan for this tube to go up and supply the other tap.

When running the tube across, ensure it takes a route which will keep it from hanging down. I ran my tube near to the underside wiring so that I have several places to secure it to.

At the socket you need to run a small length of tube from the back of the socket to a Y-connector, then connect one side of the ‘Y’ to one and the other side of the ‘Y’ to the other tap, using the same tubing.

NOTE – When connecting the tube to the Y- connector it is a good idea to use some kind of sealant to make the joint leak proof. I used a silicon based sealant and then secured each tube to the ‘Y’ using 2 cable ties

Step 5

Now it’s time to test it all. Connect your leisure battery or car leads, plug in the new pump, and get yourself a bucket of water.

Switch on a tap and check for leaks, and if all looks good, secure any pipes and wires that look untidy, and refit any panles or caravan parts you removed.

You need to seal the points at which the tubes go under the caravan. Obviously there will be a small gap around the tubes and so potentially water could penetrate. I suggest you use the silicon sealant to make a seal around them, then once it is dry, over paint this area with an underbody type paint that is durable to stones etc.
