hi,

I'm baffled with solenoid valves and hoping someone can help. I'm on my third type, all purchased from Bunnings, and all have the same problem. I'm using the 25mm 24VAC non-latching type, tried Holman, K-Rain and now Pope and they all have the same problem – when de-powered they won't block water flow.

Am I doing something wrong? These things are pretty simple – apply 24VAC to open, power off to close. I connected them to my water pipe: power off, turn on the water and no water flow – great, as expected. Power up... water flow, great, as expected again. Power off again and still water flow! The Pope is the worst, you wouldnt even know its off, K-Rain was better it blocked maybe 90% of water, Holman in between.

I tried reducing the water pressure at the tap as well, no change.

Before I resort to the latching type I'm hoping someone can tell me I'm doing something wrong. Is there an extra step I'm missing?

Thanks for any advice,

Will.
