my truma on off pull switch wont stay up and closed, so water would drain out all the time? any clues???

 

[Robert Clark]

Is there a blue button at the bottom
Press it

 

[Mikeco]

If it’s the automatic one then it might be too cold, always had a peg holding mine open in a previous van.

no just been out no blue switch......

 

[Figaro]

Yes, probably too cold for the frost protection valve to stay closed at the moment
Try running the boiler for 20 mins, assuming you can run your model dry, you can most of them

 

[Sue coulson]

yes its definately cold maybe i should wait till weather warms up a bit??

Does it rely on 12v to hold open? If so has it got power?

 

[Sue coulson]

right okay will wait until the weather warms up and hopefully it will work. thank you everyone. much appreciated

Put a clothes peg round the red button in the up position and then run up the heating, once hot it should stay up. If not it is faulty.

[Sue coulson]

[David and Sally]

At the bottom of the reply box is a button called attach files. Hit that and then locate the photo on your computer.

As said,put a clothes peg on it.

 

[Sue coulson]

Done it

 

[David and Sally]

Somebody will recognise it.

It looks electrically operated so may not have 12v to it. Fuse?

If not, my guess is that it’s too cold to stay set so maybe give it a blast with a hairdryer and try again?

As I said earlier, that is a 12v electric valve so you need to check it is getting power ie broken connections, flat battery or blown fuse,

 

[Tombola]

if its getting power, the stick a hairdryer on it then put your heater on low warm

That drain valve is also an automatic frost protection valve, that is there to prevent expensive frost damage to the water heater. So be very careful if you use a clothes peg to keep it closed. It dumps the water at about 4 degrees, so there is quite a safety margin, but best not to leave the peg on if the weather turns really frosty.

It needs a 12V supply to stay closed. It automatically opens if the 12V supply fails. Typically it's wired on the same circuit as the electric step, so if the step is not working that's a clue to possible power failure.

If you do have peg keeping the dump valve closed then keep the heating at a low setting if need be if there is any risk of the temperature dropping down to 4 or less. Better to use a bit of extra gas than risk permanent damage to the heater
