Hello all. I need some assistance. Last week we had a water softener
and RO installed. Our water is very hard, so our pipes are not in the
best shape. When the plumber put the well pump back on after about 6
hours, water started coming up in the yard about three inches above the
ground like a little fountain. We had five inches of rain the week
before. Also, the pipe to the pressure tank broke. The plumber ended
up replacing the pressure tank, valves and fixed the under the house
issues. My friend cam over and dug up the yard to find the leak in the
yard. We dug down into gravel, which was surprising, but never found
the pipe and the leak appeared to have stopped. Left the hole to watch
the water to see if it continued to fill the hole. It didn't. Then
last night my husband left the outside faucet on and the hose sprayer
closed. Upon waking, I turned it off and went outside and the hole is
full of water. So, I guess my question is: Is there a leak in my pipe
that only responds to the water pressure, or is there a pressure valve
built into the pipe from my well pump to the house that drains in the
yard when the pressure gets too high?
Any help would be appreciated. Happy 4th of July!
The plumber was here when all this happened, but at 10P when there was
no leak visible he went home. At that point everything appeared fine.
Any ideas on why there would be gravel in the area of the pipe? My
friend is a builder and was puzzled.
Answer to the first question actually asked is "almost certainly". If
it is the supply line to the pressure tank and if there is a check
valve upstream of the leak it would be isolated from pressure when the
well pump isn't running. Having seen a geyser when the pump was
running initially surely would indicate a sizable leak from somewhere.
While I guess there is some outside possibllity the heavy rains could
have some bearing on the problem/symptom, I suspect it is a red
The comment regarding possible inleakage is real and potentially quite
important. If the system were as I postulated above, not only would it
be possible to get inleakage, it would be almost guaranteed as there
would be some drawdown into the well when the pump shut off lowering
As for the gravel, it isn't unheard of to backfill a trench,
particularly if they ran the power in the same trench. I think you
need to find the pipe, and kick the pump on and see the leak. The
other comment regarding calling the plumber back is also not a bad idea
even though it sounds as this is probably not actually directly related
to what he did, if the system was so corroded it's quite possible there
were pinhole leaks before that allowed pressure relief and w/ new tank
and tight system it has now failed at the next weakest spot. If that's
the case, it may be the only real solution will be to run a new line in
Agree. In the condition the pipes are in, I wouldn't even be looking
for the leak, just cut off on both ends and lay new pipe. Maybe even
new wiring so you don't have to worry about cutting the old when
trenching for the new pipe. There is nothing to be gained by patching
a run of old pipe - leaked once, it will leak again somewhere else.
