Faucet - single handle with sprayer wand by Grohe.
I'm trying to replace the cartridge inside to stop the whistling
noise. (This was done ~1 yr ago for the same problem. The initial
whistle started ~5 yrs after the house was built.) The problem is
that I cannot shut off the hot water using the shut-off value under
the sink. Even after tight closing, there is good amount of flow to
make a real good mess. I am able to shut off the cold water using the
other value, by the way.
I saw in another thread that the value needs to be replaced. Is this
an easy job? What tools do I need? A valve failure 6 yrs after
construction - is this normal?
Also, is it normal to have the new cartridge make the whistling noise
in 1 year? I may be able to replace just the washer, but since the
original noise was followed by complete failure of the cartridge (a
part broke), I think I'll just change the whole darn cartridge. Or,
is there an easier/cheaper way to fix this noise?
Thanks a bunch.
