Tide Mill Engineers at work

I’m sure we’ve all had trouble with our penstock from time-to-time? Sometimes also called a gate valve, the Tide Mill’s penstock controls if, when and how much water leaves the mill pond and flows under the mill wheel to turn it. It is held in place by guides that make sure the gate is well seated (doesn’t leak) on the flange behind it. The guides have angled shims that push the gate backwards against the flange as it closes to improve the seal.

Our trusty team (the chap down the hole is Shaun, the one standing is Joe and Chief Engineer Rick Chapman is kneeling) were replacing the guides to ensure the Mill continues to function.
