a. I have an old gate valve (not a ball valve) outside the house that turns
off water to the house (its right at the house, not at/near the meter at the street)
the pipes from meter to house are galvanized; its an older house from the 50s.
c. I've turned off that valve a few times in recent years, for some work to be done,
and there were no leaks at it when turning it back on. But its been about 6 years
since it was turned off and on at all.
d. a few weeks ago I turned it off to look at something, and when turned it on,
a very small drip happened - about 8 ounces a day.
e. more recently had some minor work done and when turning it on,
this time its a bad drip of about a drop per second or two.
f. I've read about tightening the packing nut as a first step
to possibly solve the drip
BUT am concerned that in doing that, I might upset some other parts
of the connection of it to both the pipe coming up under the ground
from the meter, as well as the part that connects to where the pipe
goes into the house, and since its galvanized, I realize this could be a big problem
and expensive one to say the least.
or perhaps in trying to tighten packing nut the entire valve could crumble or collapse,
and there is no other main shutoff valve for the house.
=======> Are the above concerns/risks valid if will just be trying to tighten the packing nut ?
=======> If its ok to try this, does the valve need to be shut down (water turned off
at this valve) to do it, or is it ok to do it with the valve in the open position ?
=======> I am not able to any more steps like changing the packing or washers,
not to mention replacing the valve, though I guess the same concerns
with upsetting the galvanized pipe and related connections might
be valid if that work was to be done too ?
