Now in my own defense some of the time was due to unpackaging; realigning the plastic waste pipes; splicing the wiring.
However, I do get the knucklehead award for: installing the unit BEFORE I attached the electrical (result: uninstall 1); wrapping the spray head flexible hose around the main waste pipe (result: uninstall 2); and during first test I discovered water pouring out from the main gasket because I didn’t align the unit perfectly (result: uninstall 3).
But, now it works without a drip in sight!!!!!!!
I got tools.
