NUEVO FRESH WATER TANK

I appear to have a leak in my 2005 Nuevo fresh water tank.  I cannot quite see where it is coming from as I cant get fully under the vehicle.  can these things be repaired if its a leak in the actual tank or is it a new one?  If so any idea of prices?

Are you sure that th etank is leaking? There are many possibilities, including the drain tap connection and even the fact that there is an overflow hole at the top which lets excess water out if you overfill.

I have a similar problem in a 2010 Nuevo, but not a straight leak. In my case, twice - without warning - the pump started and after a minute or so water started to run out from under the motor home. I had not been using the water at the time. Is this some overflow system which is faulty? As a new member (and a recent owner of my first motorhome) I would be grateful for any advice as I cannot see any info on this in the owner's manual.

Thanks

How cold was it when this happened? If the temperature inside the van falls to 3C then the frost protection valve will open letting water out of the water heater. That would drain off all your water but you would have needed to reset the valve.

Thanks Ron
That is very helpful; it was quite cold, although I didn't think it was down to 3 degrees. However, your description sounds like exactly what happened, so do I need to reset the frost protection valve? Where is that situated?

Have you checked the inspection screw on cap? These need to be sealed if not they'll leak, had a leak on our Nuevo's tank and Auto Sleepers removed the cap and resealed it, they have to be left for 24hrs before you can refil with water to give the sealant time to cure

Our recently departed Nuevo, registered on 1st January 2010, still had the little yellow, manually operated lever. Don't know if the auto version was fitted later in the year?

(The new one may have the same after its first winter. We shall have to see if the auto dump valve is a pain in the rear. As I understand it, not all of them are a pest, but some appear to be a constant nuisance when it gets a bit chilly.)

Hi Peter
We have a blown air heating system. The handbook refers to a safety/drain valve in the cold water intake to the water heater, but my van doesn't have the same fitting as shown in the handbook - on mine there is no lever to open/close the valve. Is this significant?
Thanks
Barry

Thanks for your help Peter
I will have a go at filling the system again and see if the problem repeats itself.

All the best

Hi Peter
I have found where the valve is - in the offside under-bed storage (different place from the illustration in one section of the owners manual, but referred to elsewhere in the manual!). I hope I can now resolve the problem. Thanks once again for your help.

If the valve looks like this (only the top few photos - ignore the rest):

then you need to push in the button (not shown in the pictures) and turn the knob on top through a right angle to reset it.

Hope that helps.

PS  There is an excellent picture of the valve plus resetting instructions on p 9-12 of my manual.

Thanks Ron
Mine is the one with the blue pipe fittings and the yellow toggle lever on top. Is there any action I need to take other than put the yellow lever in the horizontal position to turn the valve off?

Best wishes

Hi Barry

Vertical is open. Horizontal is closed. That's almost all there is to it.

It is just possible that a bit of plastic swarf has got trapped in the tap, so a few wiggles of the yellow lever might be a good precaution. Do this with the hot tank full so you are letting out some water. This should flush out any trapped dross. It's a rare occurrence, but I had it once with a new van, and thought I had a leak.

You should see and feel the little plunger moving up and down as you operate the yellow lever, which is just a cam to raise and lower it.

Hope this helps

Dave

Mine in our 2012 Nuevo has a button that needs to be pressed in when you set the lever horizontal to reset it    hope it is of some help!    Regards  Paul

Thanks to everybody who replied. I am much better informed now so next time I have a problem (if I do) I am more confident I can deal with it.

All the best
