Water not shutting off at the street.

[elocs1747]

This is in a mobile home. The water has been shut off at the street using the key yet water still flows in a trickle from out of the pipe at the pit. The valve at the pit will not shut off the water completely, but turning it off outside the mobile home at the street should.

Any ideas what is happening here?
TIA

Unfortunately, this is a common problem. Try reinserting the key and moving it left or right a few degrees to see if the flow of water slows or stops. What was the reason for shutting off the water in the first place? Many home repairs can still be accomplished by opening your exterior faucets during the repairs.

Also, in my vacation mobile home, I installed my own shut off downstream of the main water shut off, so I my plumbing shut off is not dependent on the parks worn or bad shut off valves.

Try exercising the valve, turn it off then on several times. You will likely never get it to shut off completely once they are bad. Usually time to replace. Ball valves seem to work and last the longest.

This mobile home was empty during this past horribly cold Wisconsin winter.
The heat tape worked fine under the trailer, but the compression fitting where the pipe goes into the house failed and water was leaking from it. So the park manager shut off the water from the street. Unfortunately that still allowed some water to flow through the pipe, but not enough pressure to go through the faucets. The long and short of it was that water froze going to a sink at the opposite end of the mobile home.

Fixing that leak under the sink should be fairly straightforward, but I wanted to replace the compression fitting on the pit end and where it goes into the house because I have had horrible luck with compression fittings and they seem to fail no matter what I do. I want to solder the pipe at each end, but that's a problem with water coming out of the pipe at the pit end.

That key only turns about 90 degrees from full on to full off, so backing it off a little from full off might work? (There are no exterior faucets, but there is one just above the shut off valve at the pit under the trailer, so might opening that pull the water away from where it exits to allow soldering?)

Turning the valve on and off a few times with water flowing through it sometimes helps, as the sediment will tend to break loose and be flushed out of the valve.

If the faucet you are talking about is between the defective valve and your repair point, and is lower than your repair point, then it very well might keep the water from getting to the repair point.

I tried the faucet first and it worked like a charm. There wasn't enough water pressure to push it past that point. That faucet never got used because its handle is right on the waste pipe coming from the far end so it is a real pain to turn, but it worked.

Thanks for the tip.
