Water leaking just bhind pump

[kevrandle]

Hi,

Just preparing my Lunar 525 for a trip. When pump is running nothing to tap but water running from undeneath caravan just behind where the pump attaches. Could it be some frost damage to piping? any suggestions very welcome.

Kev.

Have you left the drain open for the water heater?

 

[kevrandle]

No, unles it is open 'by default'. Can you tell me where to look?

Thanks.

If you have a Truma Ultrastore water heater, the drain valve is located on the floor near it. It is a grey unit with a yellow flip over tap on the top, which when in the upright position is OPEN.
Laying down either way is CLOSED.

The other possibility is a under van drain bung is missing.
