HI all,

I took delivery (picked up) a fresh van on Friday, an ABI Award Nightstar so on Saturday I set out my stall to run and check all systems.... all seems fine on initial checks apart from the cold water flow.

When i turn on the hot water tap at the sink the flow is fine but when I turn on the cold it is little more than a trickle ? I have just fitted a new whale pump as the seller told me the old one had burned out (it was old when I went to remove it).

Any ideas why this should be ??

I should mention that my leisure battery is due for replacement but the charge showed just under the green and seemed to pump the hot system ok but why so slow on the cold, is low charge the reason perhaps?

Oh and when the caravan is plugged into the mains should this automatically charge the battery ??

Hope you can shead some light for me

Cheers

A couple of things could be wrong.

1 The tap needs cleaned,take of nozzel at the end if its got one and clean out.

2.Pressure switch needs altered.

3 The battery should charge itself unless you have an off/on switch.


I would go with cleaning out the tap first..

as above but possibly a faulty tap.turn on cold tap then turn on hot tap,if cold runs then you could have a faulty micro switch on the cold tap if you have micro switches that is.(hot tap making the pump run).

Hey all

Thanks for all the replies, I will pop out tomorrow and try and see if it is the microswitch and replace as necessary.... sounds the most likely culprit.

I assume replacing the switch is straight forward?

Will pop over to flea bay and have a look see how much they are..

Thanks again.

Oh ok, I took a look at the link Michael posted above and it seems that on the Whale tap the microswitch is underneath so just a case of taking off the old and installing a new one ? The access underneath is good as I can just take out the drawers.....perhaps my big sausage fingers may be my worst problem !!

Took a look at e-bay and it seems to list loads of whale microswitches at not took much dollar, will take off the old and see which before i order as I assume their are different types?

Will let you know the outcome

Cheers

if same this may help,just a thought,if the micro switch does not do the job.it could be the knob on the tap as these suffer from broken shafts and worn knob insides.this gives an indication you are turning on the tap when in fact the inside workings of the tap is not moved.to remove the micro switch,remove the oblong collar (10) this will release the micro switch.
