The 7yo Delta had stopped rotating and the based cracked and leaking. Garbage.
The new is taller for comparison.
Need at the very least 15" plus 6+" height for about all of them.
*Spray function is good for washing food in a strainer. Must be sure the pull hose is clear of all pipes underneath and lines straight.
*Only one center nut. This one was lacking screw-in plates for the other two holes and will flex with my cheap sink basin. I shimmed up a board underneath under the back shelf as a brace.
*Also used silicone sealant around the base and was careful to make sure the very thin base washer (which wanted to pop out) was kept in place. Had to pull on the hose to make sure everything stayed seated while tightening the nut from underneath. The nut was small and oblong to slip over the hose fittings and didn't wand to thread easily.
*The red hose was hooked to the hot water pipe but the function was still reversed from the dots on the handle. Oh well.
