Water going straight to overflow when tap opened

[El Morris]

Hi all.

So everything was working fine until last evening when we found the leisure battery was empty. It had emptied during the day even no one was in the van.

So we plugged into 220v and when we turned the tap on no water was coming through the tap but straight out of the overflow? The water tank was 75%full

Maybe these two changes are coincidental?

Does anyone have an idea why the water would go to the overflow?

Thanks
Elli

Sounds like your draindown valve is open. Is it electrically controlled?

Check the frost valve next to your water tank has not opened because the temperature has dropped.

OK. I'm not sure the van is new to us. Do you know if there is normally an electrical switch for this or is it a tap near the tank?

OK, thank you. We are in Spain so temperature are still above 17 by night. I will try and see if I can see that valve

It is simple to reset, check your handbook as to where it is and how to reset it. I have been there and done that.

Is your waste water tank full and overflowing? Or the valve open on the waste tank? The know that may be a bit ‘Janet & John’ but….

Good to know. Our van is 28years old and the handbook is in German. What is the name of the part/switch and maybe I can see if its online?

Waste tank I can say is definitely not full. It was emptied last 2 days ago. I will look on by the waste valve too, thanks

If the van is 28 years old I would think it was an earlier type of valve with the pull up knob, not the one shown.

could be like this next to the boiler.

 

[TheTwoOfUs]

It could be similar to this.

Thinking about this, if the automatic drain is open then when you turn the tap on it will allow air into the system and help the water out, can you hear the water pump start up or not?

 

[El Morris]

When the tap is opened the pump starts everything. This is a photo of what is next to the boiler. On off switch works but no moment from yellow button

Can't see one of these but posted a photo above of something maybe it but nothing changing

Also, we have detached the 220v and tested the habitation battery. Only reading 11.5v. Looks a bit old so we'll replace that. So, we will be on hook up until battery is changed
