My bath/shower handle (SYMMONS Model A) knocks loudly when I turn it
off with the diverter set to the bath. If I leave the diverter set to
shower, it does not knock when I turn it off. My questions are:
· Is there some part speccifically that probably needs to be
replaced, or should the whole handle be replaced?
· I do not have access to the plumbing in the wall. Can the issue
be repaired through the handle?
· I have a shower hose and spray attachment installed. The SYMMONS
web site states it should not be installed due to back pressure
issues. Could this be a reason for my problem?
Any help will be appreciated.

It sounds like water hammer or a loose pipe. Hold the bath spigot when
you turn the water off and see if it moves. If it does something is
loose and is banging against something else.
Another suggestion would be remove the shower hose and spray
attachment to see if that's the problem. The manufacturer said don't
use it...you're having a problem...so let's take the first logical
step and see if removing it helps.
Of course, even easier than that might be to call SYMMONS and ask them
what the specific problems could occur if a shower hose and spray
attachment were used. Don't accept "back pressure issues" as the
answer - find someone who will tell you exactly what the "back
pressure issues" will do to the system.
Finally (or first) you could try this:
Close the main water shutoff.
Open all the faucets you can and flush the toilets to drain the entire
Open the main shutoff.
Close the faucets, starting at the farthest/highest one and working
your way down and towards the main shutoff.
If you have any water hammer buffers built into your system, this
might refill them with air and eliminate the problem.
I held the bath spigot and it did not even vibrate when the knock
I removed the spray attachment and the knock still occurs with the
diverter set to bath only.
I actually had a water hammer installed originally when I bought the
home 8 months ago. Then I realized the knocking only came from the
tub (while the diverter is set to tub - not shower). No other item in
the home creates even a small knock.
I'll call SYMMONS on Monday.
Thanks for your suggestions.
