Truma frost valve

[Stubear]

My valve is weeping - works fine to fully dump water but when closed there is a steady drip - I know I can buy a new one for £150 but wondered if anyone out there had repaired rubber seal and it looks adjustable

Worth taking it off and soaking in a dilution of citric acid or white wine vinegar as it may be a calcium build up that's causing the promlem.

try opening and closing a few times that might fix it.

DITTO... Small bits of debris can get into the valve and cause dripping. Had it on a past van.. Flushed the tank and problem cured.
