Decommission old water tap - seal pipe

Hello everyone,

I am currently not building a house, but ours has already been standing for about 200 years. However, one is always tinkering, and so am I.

In our garden, there are water taps that have so far been connected to the house water, but have been shut off for a few years by a ball valve. We now want to operate these with the garden pump.

The path is not yet opened, as I want to gather some information first before the Knochensteinweg lies open for days until I have the information. So everything is a bit vague. Sorry for that!

I assume the worst, that I will not encounter any thread or that I cannot reuse it. I assume the pipe is steel or copper. So I thought about sealing the pipe with a clamp fitting - the pipe to the house water is secured by the ball valve and a non-return valve (was certainly professionally installed). It is only about making it tight enough in case I want to use it again.

Can you tell me if I can simply close the pipe with this and do I need to solder or weld it additionally to make it tight, or is it enough to just slide it over the pipe and screw it tight? That’s how I know it from PE pipes, which I use for my garden irrigation and also want to use for this.

Do I need to pay attention to anything special or do you have any other tips?

Many thanks and best regards

Felix

The water pipe is best shut off at the point where it branches off from the used pipe. Otherwise, germs may form. Screw in a threaded plug at this point. Using any kind of clamp plug could cause problems with the insurance in case of damage.

Thank you very much for the response. That is a good idea. Then I would do it that way. The valves are embedded in a box in the floor of the barn. Then I would simply cut off the pipe and unscrew the loose part from the valve, and, as you suggested, put the plug on it. Opening the entire cobblestone floor up to the stable... would be too much work for me, especially since I don't know exactly how it runs.

Thank you very much and best regards

Felix
