I posted a similar msg about a month ago, but got no replies..thought I
would try again.
The following problem has been going on since a Delta 2 handle, shower only,
faucet (and new shower) were installed 5 years ago. It's driving me nuts,
and nobody seems to have any idea what I should do. I would be greatly
appreciative if someone could give me a suggestion.
A few months after this was installed about 5 years ago, the water pressure
gradually reduced to a very poor level. (about 1.4 gal/minute) I tried the
usual things: of course took the shower head off; also removed the valves
and purged into the shower from the source -- tons of pressure, no help.
Then, assuming that the clog was between the faucets and the head, I removed
the valves, attached a garden hose to the head pipe, and flushed out from
the head out into the shower thru the valves. THIS WORKED (2.5
gallons/minute), BUT ONLY TEMPORARILY. Within a week or two the pressure
began to decrease again. I have done the above 3 times now. Each time it
fixes the problem for a while, and then reverts back to poor pressure.
My only conclusion is that there is some stuff lodged north of the valves
and with time, it moves to a place where it can constrict the flow. I have
tried snaking some wire from the head down..but could only reach about 3/4
down towards the faucets. OR something is wrong with the valves, but I can't
imagine what. The pipes from the source are copper..the pipe going up to
the head is older (galvanized?)
Do you have any thoughts? I'm about ready to bust up the wall and replace
everything from the faucets on up (I really don't want to do that)
Thanks very much
