Hi,
Further to simpics thread (//www.diynot.com/forums/plumbing/water-butt-filling-question.361735/), I have been trying to come up with a cost effective way to have my water butt filled up by the mains as a backup to maintain a minimum water level.
My proposed solution involves a float which is buoyant enough to suspend a weight, and the weight needs to be heavy enough to open a valve when hanging freely.
On the attachment:
1. Water butt is full to the point of the overflow. Slack on chain connecting float to valve means valve remains closed in this state as weight is prevented from pulling on valve by float.
2. A few dry days and the water level decreases to a level where the float is suspended out of the water and no longer prevents the weight pulling on the valve, which it does, opening it and mains water begins to flow into the water butt.
3. The water level reaches the minimum level where float is now suspended and again creates slack on the chain as the weight is prevented from acting on the valve and the valve closes stopping the water flow.
So my question is, does such a valve exist? Could it stand the force of the mains pressure? And how cheap can I pick one up?
