Our Ultrastore has the standard yellow valve but also a push in button at the side which needs to be engaged at the same time. This stops the incoming water from draining out. Had me foxed at first 🤔.
The truma hot water service should really be renamed to The Trauma hot water disservice. I wasted money on one in 2015 then replaced the tank that split then replaced the whole hot water service thinking I may have just got a dud then I discovered after replacing two more tanks that they are completely fucked with a lifespan of one to two years and they will not honour their shit dysfunctional rubbish...
