    I did address it personally. Redoing straps, adding straps, isolators, thrust blocks, foam .... to be honest I don't know where this knocking could be taking place.

    Not likely. It is all new(ish) SCH80 PVC personally installed by me.

    Backflow is not part of the house system. It is isolated before a whole house water filter, and there is no irrigation on the lot.

    Copper, type L throughout the house. 1" cold water main, to 3/4" laterals, to 1/2" at the outlets. The amount of 1/2" on the toilets is about less than 1 foot before it hits 3/4" and about 9 feet before it hits the 1" main. On this particular toilet, it is just the stub out length that is done in 1/2". There might still be some debris in the lines that aren't in service yet. They have been "flushed", but not really flushed well IMO.

    I have done none of these, but the beer sounds like a good idea. Got other fish to fry right now. I do have gauges before and after my water filter so I can track filter performance. I did have some air in the lines that was causing my water heater to kick on momentarily when the toilet valve closed, but I got that air out. I have seen some pretty wild fluctuations in city pressure, but it doesn't make it through the filter.

    The wall that holds the toilet plumbing. First pic is how the plumber left it, 2nd pic is how I fixed it.

    but what makes an ESP-SMT send current to at least one or more of the zone valves, even in the OFF position (yet not the MV)

    further, a flow control bonnet MV: in the completely open postiton (concerning flow control), would be similar to a non-FC bonnet, correct?

    or in other words, if FC all the way open, with main and laterals empty, velocity could be potential quite high if i understand correctly?

    The answer to your dilemma may be the answer to this question "why does a whale, the largest animal on the face of the earth, only have a throat the size of a dinner plate?"
