A water meter fiddle?
I was doing a routine check for water leaks at home today, I just observe
the little 'spinning' wheel on the water meter with everything turned off to make sure it's not moving - it wasn't. Then I started thinking. The meter works by way of a little turbine wheel that spins in proportion to water flow and is geared to the counter unit. I wondered if the turbine needs a certain minimum flow of water to overcome the meter's internal friction. So, by opening a cold tap just a tiny amount (just little more than a constant stream of drips) I observed that the meter wasn't rotating at all. My theory would appear correct. So, what if I fitted two ball cocks to the DHW header tank? One half way down the tank to work normally and one at the top with a stop valve upstream throttled to allow a drip feed only. With this working 24/7 I should get 'free' water maybe? I'm not from Yorkshire BTW, I just like the idea of getting something for nothing! Julian. |
