Here's an unfortunate problem! I've been wondering why water consumption has been so high. I noticed that the geyser overflow pipe was draining directly into the gutter, pretty well continuously - it must have been doing this for some time.
When I turn off the supply to the geyser it stops. I thought it might be some sort of siphon effect, so I tried leaving the hot tap on to clear the pipe, but, when I turn the geyser tap on, out comes the water again.
It looks as if the emergency overflow valve is stuck in the 'open' position. How does this happen? How do these things work? Is there a way of closing it or do I have to get a new one?
If I have to get a new one, how difficult are they to fit? It's an awkward space, I can see that, but, if it was just a matter of a spanner in the right place it might not be too bad.
Any advice gratefully received.
