Yes, and while you are chaning it out, you should install that missing















shut-off valve.

I have never seen a well pump with a valve (other than a check valve) on its















outlet to the pressure tank.































And I've never seen one without it. Every appliance using/supplying water should have one for just such a reason. It recently cost me $120 to have a shut-off installed on the well line entering the house where I forgot to specify it when the well was drilled. That was an unusual situation though. I had a leak and needed to shut that line off to isolate it.

You're confusing a shutoff valve for the water supply *to the house*, with







a shutoff valve between the well and tank. Of course there should always







be a shutoff between the tank and the house. But I've never seen one







between the well and tank. What purpose exactly does it serve? Assuming







it's a submersible, all it does is block the flow of water into the tank







which you could just as easily do by shutting off the breaker.







If the tank has 60 gallons of water, that water will still be available







to run into the house, unless there is a valve between the house and tank.







Here is why it would be useful to have a shutoff valve between tank and well.

The valve he shuts off is *not* between the tank and the well. The

valve is between the tank and the house water lines. I don't understand

all the confusion here. To drain any sediment, all you really need to do

is:

You are right. My bad. That is a shutoff valve to the house.
