Yes, can't do any harm and might solve the problem.

"where the water smelled like swimming pool" and "there have been hundreds of gallons made have all turned out excellent using the same routine". While I daily read opinions of how chorine spoiled their beer, that's something I've to experience in fifty years of brewing.

So this can be ruled out as the cause.

I'm not on a meter, so no concern for me, but after chilling yesterday's brew I'd collected 10 litres of very hot water, 10 of quite hot water and 40 litres of warm water for cleaning. Maybe 30 pence cost to metered properties, but worth it many times over for the improvement in the finished beer although it's maybe not the cause of your current problem.

I'd agree. While your current water doesn't appear to have the mineral qualities necessary to make a great stout, those properties don't cause the troubles you have. I'm wondering if the lesser level of chlorination has exposed a weakness in your sanitation procedure?
Without patience, life becomes difficult and the sooner it's finished, the better.
