Frost control drain valve.

The sun is out so lets get moving, but, can anyone tell me how to fill my water tank via the dreaded whale system when the temp. is still cold enough to open the frost control valve. I have tried to push the button in but it keeps opening to drain.

What year is your Nuevo as mine is a 2011 model but it does not as far as I am aware have a frost control valve. In fact the other week we were on the top of Dartmoor and it was -3C and had no problem with the waste apart from the morning we left I could not fully open the pull out waste drain valve at the rear as it was frozen! It had thawed out by the time we returned home. Was the valve fitted as an extra?

Hi Moggy, The valve was standard on my 2012 Nuevo. It opens the drain at I think 3C. It has been OK this afternoon and I managed to close it as the weather has been good today, but I dont know how I would go on if the temp. dropped when on site.

Hi JHT I assume the valve is electrically operated so wonder if you could simply disconnect the power lead to it? I do not know why they need to fit this as you could be on site as you say and the whole freshwater tank could drain out unbeknown to you and then if hot water is drawn off the hot tank is not going to refill.

If you turn on the heating and take the chill off the van it will operate. You can also use a hairdryer to warm it up.

There are two types used electrical and mechanical. The electrical version needs power and if you disconnect it then it will dump the water. The mechanical versions need the temperature to be above 3c.

It is an important safety feature to protect your boiler.

Thanks for the replies. I wont forget to pack the hair drier !

Hairdryer even,

I queried this with Marquis the other day, the dump valves are very sensitive but if you keep the water warm they will not dump water. It is possible to have a manual valve fitted ( about an hours work) if you find it that much of a problem

Thanks for that groundhog, we are off to Hawes on Monday for a few days so looking forward to our first outing this year.
