Looks great that👌, my Mk8 has a small delay with the washer jets too, I presume it’s normal, but annoying none the less, I actually bought some in line non return valves to add to the washer tubing, but decided against adding them, as I’ve been told that in this case, the water being allowed to drain back is by design, and a preventative measure to reduce the chance of freezing during cold weather, I’ve no idea if that is correct or not, but they have never frozen up, mine has heated washer jets, but so did my Mk7 and that would freeze in the tubing if cold enough. 🤷♂️
