I need to remove the shower head on a delta monitor. I have never done this
before. Do I need to turn off the water supply? I'm assuming that the
shower head just unscrews. Will I need to put some teflon tape over the
threads before I screw it back on? I can see that there is some on the
threads now. The problem is there is reduced pressure to the showerhead
for a while and then after a couple of months, the pressure is good for a
while then back down again. I'm assuming there is some debris in there that
moves around. Main thing I need to know is whether to turn the water supply
off first. The showerhead is 7 years old and worked great until the last
You have the water shut off with the shower control valve (like you do when
you're finished with your shower), and of course no water is coming out of
the shower head.
Removing the shower head at this point shouldn't require any additional
shutting of valves.
Maybe I'm missing something or I didn't understand the question.
One danger is that in trying to unscrew the shower head itself, there
is some chance of unscrewing where, inside the wall, the other end of
the (usually a short section of chromed pipe etc) screws into a
fitting. And then later, and being hidden that may leak (inside the
wall)? So two wrenches may be needed; one to hold that pipe so it does
NOT turn (and take the strain, as t were) and something else to turn
(unscrew) the shower head.
However before assuming it IS the shower head! Another cause could be
that a washer or something else inside the mixer valve that supplies
the not-cold water mix has become defective. There may be debris
inside the shower head or pipe or maybe not.
It is for that reason we have never installed a shower mixer control
on our bath tubs; preferring the much simpler approach of separate hot
and cold valves. Others say mixer valves work well for many years so
in this case it may be nothing to do with the shower mixer temperature
control valve. But might be best to check first.
Just the part outside that controls it. May drip a little on you from the
trapped water but nothing more.
Proabably wont need new tape.
Juat be careful to hold the arm piece that goes into the wall well so you
dont accidently unscrew it any. If you do, you'll probably need help
getting that fixed and have a leak inside the wall until then.
Could be you just have a degrading washer in there so you'll be able to see
that, lift it out, and get a matching one at a local store.
You might try this first:
1. Take a 2-quart (or so) plastic (ziploc) bag and fill it with vinegar.
2. Use duct tape to immerse the shower head in the bag (or bucket) of
3. Let the thing percolate for a few hours.
4. Remove bag.
The weak acid vinegar will dissolve a lot of the crud in the shower head. It
may even dissolve enough so that everything returns to normal.
I nominate HeyBub's reply for "Best in Thread". Addresses the problem
and proposes a good solution.
And by the way, as someone else noted above, no need to shut off
anything except the shower valve: then no water will come out of the
shower head, right?
