Hi All, Thanks to the "Fixed it Club", Wizard, and 6 months of winter slogging we have had our second successful trip in our now very dry!!!! caravan.
While we were on site we saw people using pumps attached to their water hogs via a whale socket. (I have a whale socket!!!).
I was using our woefully inadequate 9 litre on board tank which I had to fill several times a day by switching the water switch on the power panel to external and using a pump in an outside plug. I then had to switch the plug to internal so the taps would work.
I subsequently purchased a premium pump for my whale socket. You all know whats coming.......it does not work.
All my taps are microswitched so I thought, fill the hog, switch tap on.
Should it work with my other water system or independently? I have tested the pump with a 12 volt supply and it works so could it be the 12 volt from the van?
My power panel only has a switch for the onboard tank. So I guess there should be a way to turn the whale on and off. I have traced the live wire (yellow/with brown stripe) back to a connecter on my power panel but it then goes inside and the unit is riveted together.
Should the live and the tap microswitches link up somewhere?
I think on the newer Compass they also have a external whale socket and internal pump. I think the whale water master should work with your internal tank. Do you have a water level indicator anywhere for the internal tank?
My outfit is a 1998 Compass Pentara 500/4 but to answer your question it has a dual purpose rocker switch on the control panel where you can check battery status and internal water tank level. I have not heard back from Whale yet but will post as soon as they answer.
Cheers.
Problem solved thanks to the clues from Rob Dashwood. I thought forward from his comments and connected the Whale Watermaster. I then set my on board system to external and turned on the tap.
Result!!! Water flowed beautifully from the taps in conjunction with the working Whale Watermaster.
I guess that the on board external pump circuit and the Whale external pump circuit must be linked. I don't yet know if using the Whale pump externally will fill my on board tank but it does fill the water heater so all is well.
Thanks for all the help and all kudos for Rob for pointing me in the right direction.
