I have a one-year old Moen Extensa faucet in my kitchen, which, when new,
would always start in "stream" mode when the water was turned on. If you
wanted it to go into "spray" mode you had to switch it to spray while the
water was running. It would always revert back to stream when the water
stopped. In the last couple of months it's gradually changed its behaviour
to that whatever mode (stream or spray) was last used is the mode which it
now starts in. Was it broken to begin with or is it broken now is my
question??!! Is this common. Has anyone got a solution? Maybe there's
something that needs cleaning. I don't have a hard water problem so I don't
think it's calcium buildup, but even if it were I'm now sure how I'd get
into the "head" of the thing. Thx.
